Answer 1

The vertical distance the Mars Rover Curiosity has traveled is approximately 84.954 meters.

What will be the absolute value equations in the form |x-b|=c for x ≤ -14 and x ≥ -1.3?

An absolute value equation is an equation that contains an absolute value expression, which is defined as the distance of a number from zero on the number line. The equation |x-b|=c represents the distance between x and b is c units. To write the absolute value equations in the form |x-b|=c, we need to determine the values of b and c based on the given solution sets.

For the solution set "All numbers such that x ≤ -14", we know that the distance between x and -14 is always a non-negative value. Therefore, the absolute value of (x-(-14)) or (x+14) is equal to the distance between x and -14. Since we want x to be less than or equal to -14, we can set the absolute value expression to be equal to -c, where c is a positive number. Hence, the absolute value equation is |x+14|=-c.

Similarly, for the solution set "All numbers such that x ≥ -1.3", the distance between x and -1.3 is always a non-negative value. Therefore, the absolute value of (x-(-1.3)) or (x+1.3) is equal to the distance between x and -1.3. Since we want x to be greater than or equal to -1.3, we can set the absolute value expression to be equal to c, where c is a positive number. Hence, the absolute value equation is |x+1.3|=c.

Answers

When all 967 tickets are purchased, the probability of not winning is 0 (or 0%).

What is probability?

The probability of an event occurring is defined by probability. There are numerous real-life scenarios in which we must forecast the outcome of an occurrence.

To find the probability of not winning the TV with a given number of tickets, we need to calculate the ratio of the number of losing tickets to the total number of tickets. The completed table is as follows:

Answers

Antonio's weight after 5 weeks was 202.34 pounds, and it took him 19 weeks to weigh in at 161.05 pounds.

To find Antonio's weight after 5 weeks, we can simply substitute t = 5 into the given exponential function:

W(5) = 235(0.985)⁵

W(5) ≈ 209.88 pounds

So his weight after 5 weeks was approximately 209.88 pounds. To find how long it took him to weigh in at 161.05 pounds, we can set the function equal to 161.05 and solve for t:

161.05 = 235(0.985)ᵗ

Answer:

Step-by-step explanation:

Let's call the total volume of the container "V".

We know that the container was originally 15% full, so the amount of water in the container was 0.15V.

When 48 litres of water was added, the new volume of water in the container became 0.15V + 48.

We also know that the container is now 75% full, so the new volume of water in the container must be 0.75V.

We can set up an equation to solve for V:

0.15V + 48 = 0.75V

Subtracting 0.15V from both sides:

48 = 0.6V

Dividing both sides by 0.6:

V = 80

So the container can hold 80 litres of water when it is full.

Answers

The best estimate for the elk population is b) 1,250.

To estimate the elk population, you can use the mark and recapture method. The proportion of marked elk to the total marked population should be equal to the proportion of marked elk observed in the sample to the total observed population.

So, (marked elk / total marked population) = (marked elk observed / total observed population)

In this case: (75 / total population) = (15 / 250)

Now, solve for the total population:

75 / total population = 15 / 250

Cross-multiply:

15 * total population = 75 * 250

total population = (75 * 250) / 15

total population = 18,750 / 15

total population = 1,250

The faces of a rectangular prism have areas of 9, 9, 25, 25, 49, and 49 square meters. Find the volume of the rectangular prism, in cubic meters

Answers

The volume of the rectangular prism is 105 cubic meters.

To find the volume of the rectangular prism, we can use the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

Since there are three pairs of congruent faces, we can deduce that the areas of the three pairs of faces represent the three dimensions of the rectangular prism. The areas are 9, 25, and 49 square meters, which are the squares of the sides' lengths.

Take the square root of each area to find the corresponding side lengths:

√9 = 3 meters
√25 = 5 meters
√49 = 7 meters

Now, apply the formula to find the volume:

V = lwh = 3 × 5 × 7 = 105 cubic meters.

A person stands on level ground 60 m from the nearest point of a cylindrical tank of radius length 20 m. Calculate:


a- the circumference of the tank


b the percentage of the circumference that is visible to the person

Answers

The circumference of the tank is is 125.66m and the percentage of the circumference that is visible to the person is 10.24%.

a) To calculate the circumference of the cylindrical tank, using the formula C = 2πr, where C is the circumference and r is the radius of the tank. In this case, r = 20 m, so:

C = 2π(20 m) ≈ 125.66 m

b) To determine the percentage of the circumference visible to the person, we first need to calculate the angle (in degrees) that subtends the visible arc. This can be done using the inverse tangent function:

angle = atan(opposite/adjacent) = atan(20 m/60 m)

angle ≈ 18.43°

Since the visible arc is symmetrical on both sides, the total angle of the visible arc is twice the calculated angle:

total angle ≈ 36.86°

Now, calculate the percentage of the circumference that is visible by dividing the total angle by 360° and multiplying by 100%:

percentage = (36.86°/360°) × 100% ≈ 10.24%

So, the visible percentage of the circumference to the person is approximately 10.24%.

Alec bought a house. By the end of the first year, the value of Alec's house had increased by 1%. By the end of the second year, its value had decreased by 10% of its value at the end of the first year. Use multipliers to work out the overall percentage decrease in the value of Alec's house for this two-year period

Answers

The overall percentage decrease in the value of Alec's house for the two-year period is 9.9%.

Let's assume the original value of Alec's house as $100. After the first year, the value of the house increased by 1%, which means the new value of the house is $101.

Now, in the second year, the value of the house decreased by 10% of its value at the end of the first year. Therefore, the new value of the house at the end of the second year can be calculated as $101 - (10/100)*$101 = $90.90.

To find the overall percentage decrease in the value of Alec's house for the two-year period, we can use the formula:

Overall percentage decrease = [(Original value - Final value)/Original value] * 100%

Substituting the values, we get,

Overall percentage decrease = [($100 - $90.90)/$100] * 100% = 9.9%

Therefore, the overall percentage decrease in the value of Alec's house for the two-year period is 9.9%.

please help me because i really need with this question <3

Answers

The pool has approximately 258.2 square feet of plastic material. Rounded to the nearest tenth, the answer is 258.2 square feet.+

To calculate the surface area of the pool that is lined with plastic material, we need to find the area of the curved part and the area of the top and bottom circles.

First, let's find the radius of the pool, which is half of the diameter:

radius = 11 feet / 2 = 5.5 feet

The curved part of the pool is a cylinder with a height of 2 feet and a circumference of [tex]2 * π *radius:[/tex]

curved area = height * circumference

[tex]curved area = 2 feet * 2 * 3.14 * 5.5 feet[/tex]

[tex]curved area = 68.2 square feet[/tex]

The top and bottom of the pool are two circles with a radius of 5.5 feet:

circle area = π * radius²

[tex]circle area = 3.14 * 5.5 square feet[/tex]

[tex]circle area = 95.0 square feet[/tex]

To find the total surface area of the pool that is lined with plastic material, we add the area of the curved part and the area of the top and bottom circles:

Total area = curved area + 2 * circle area

Total area = 68.2 square feet + 2 * 95.0 square feet

Total area = 258.2 square feet

Answers

The volume of the large box is 200 cubic inches. The volume of the small box is 150 cubic inches. The difference in the volumes of the two boxes is 50 cubic inches. The units that should be used for each of these answers is cubic inches.

To find the volume of each box, we'll use the formula for the volume of a rectangular prism: Volume = Length × Width × Height.

For the larger box, the dimensions are:
Length = 8 inches
Width = 2.5 inches
Height = 10 inches

Volume of large box = 8 × 2.5 × 10 = 200 cubic inches

For the smaller box, its length is 75% of the larger box's length:
Length = 0.75 × 8 = 6 inches

The width and height remain the same, so the dimensions are:
Length = 6 inches
Width = 2.5 inches
Height = 10 inches

Volume of small box = 6 × 2.5 × 10 = 150 cubic inches

The difference in the volumes of the two boxes is:
200 cubic inches - 150 cubic inches = 50 cubic inches

Hence,

a⁻¹³ will become 1/a¹ and a⁻⁶ will become 1/a⁶

Hence the numerator and denominator will interchange to get

Now, we know that when a number is broght from denominator to the numerator, there is a minus sign added to the power. Hence we will get

a⁶ X a⁻¹³

Since the two numbers have the same base- a, we can add the powers up as there is multiplication sign in between to get

Answers

The area of the shaded region is 422.8 m², rounded to the nearest tenth.

To find the area of the shaded region, we first need to determine the areas of the two shapes that make up the region. The first shape is a rectangle with dimensions of 18.6 m by 30 m, which has an area of:

Area of rectangle = length x width = 18.6 m x 30 m = 558 m²

The second shape is a semi-circle with a diameter of 18.6 m, which has a radius of 9.3 m. The area of a semi-circle is half the area of a full circle, so we can use the formula for the area of a circle to find the area of the semi-circle:

Area of semi-circle = (1/2) x π x r² = (1/2) x π x 9.3² = 135.2 m²

To find the area of the shaded region, we need to subtract the area of the semi-circle from the area of the rectangle:

Area of shaded region = Area of rectangle - Area of semi-circle
Area of shaded region = 558 m² - 135.2 m²

B. Collect and store digital information about a location?


C. Track the location of moving objects on Earth?


D. Organize and represent data for a location?

Answers

Answer:

Step-by-step explanation:

Geographers use satellites primarily to capture detailed images of a location from space (option A). These images can provide valuable information about the landscape, climate, and natural resources of an area, among other things. Additionally, satellites can be used in combination with other technologies to collect and store digital information about a location (option B), such as mapping the distribution of vegetation or tracking changes in land use over time. While satellites can be used to track the location of moving objects on Earth (option C), this is not typically their primary function. Finally, organizing and representing data for a location (option D) is more closely associated with Geographic Information Systems (GIS) than with satellite technology specifically.

Answer:

A. Capture detailed images of a location from space.

How can the magnitude of an earthquake be calculated when its intensity is 10,000 times that of the reference earthquake?

The correct equation that calculates the magnitude, M, of an earthquake with an intensity 10,000 times that of the reference earthquake is option B: M = log(10,000/Io).

In the given equation M = log(I/IO), I represents the intensity of the earthquake being measured, and IO represents the intensity of the reference earthquake. Since the intensity of the earthquake in question is 10,000 times that of the reference earthquake, we substitute I with 10,000 times IO.

Therefore, the equation becomes M = log(10,000/Io), which is option B. This equation allows us to calculate the magnitude of the earthquake based on the relative intensity compared to the reference earthquake.

a = 0b = 1c = 1f(y) = yg(y) = 2 - yh(y) = 0k(y) = y

Given Integral:

[tex]\int\limits^1_0 \int\limits^{2-x}_x {F(x,y)} \, dydx = \int\limits^b_a \int\limits^{g(y)}_{f(y)} {F(x,y)} \ dxdy + \int\limits^c_b \int\limits^{h(y)}_{k(y)} {F(x,y)} \ dxdy \\[/tex]

To write the equivalent integral with the order of integration reversed, express the limits of integration and functions appropriately.

Reversed integral:

[tex]\int\limits^b_a \int\limits^{g(y)}_{f(y)} {F(x,y)} \ dxdy + \int\limits^c_b \int\limits^{h(y)}_{k(y)} {F(x,y)} \ dxdy \\[/tex]

Now, let's determine the values of the variables:

a = 0: The lower limit of the outer integral remains the same as the original integral.

b = 1: The upper limit of the outer integral also remains the same as the original integral.

c = 1: The upper limit of the second inner integral is determined by the limits of integration of the original integral, which is 1.

f(y) = y: The lower limit of the first inner integral is the same as the original integral, which is y = x.

g(y) = 2 - y: The upper limit of the first inner integral is determined by the limits of integration of the original integral, which is 2 - x.

h(y) = 0: The lower limit of the second inner integral remains the same as the original integral.

k(y) = y: The upper limit of the second inner integral remains the same as the original integral.

Square $ABCD$ has side length 7. What is the length of the diagonal $AC?$ (its a square also)

Answers

The length of the diagonal AC in square ABCD is approximately 9.899 units.

To find the length of the diagonal AC, we can use the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In our case, since ABCD is a square, angle ABC is a right angle. Therefore, triangle ABC is a right-angled triangle with sides AB and BC both equal to 7 units. We can apply the Pythagorean theorem to find the length of diagonal AC (the hypotenuse):

AC² = AB² + BC²

Plugging in the side lengths:

AC² = 7² + 7² = 49 + 49 = 98

Now, we take the square root of both sides to find the length of AC:

AC = √98 ≈ 9.899

So, the length of the diagonal AC in square ABCD is approximately 9.899 units.

What is the Fundamental Counting Theorem?

The Fundamental Counting Theorem states that if there are m ways to do one thing and n ways to do another, then there are m x n ways to do both.

This can be extended to more than two events, where the number of ways to do all the events is the product of the number of ways to do each individual event, according to the equation presented as follows:

A rectangle is changing in such a manner that its length is increasing 5 ft/sec and its width is decreasing 2 ft/sec. at what rate is the area changing at the instant when the length equals 10 feet and the width equals 8 feet

Answers

The area of the rectangle is changing at a rate of 20 ft²/sec when the length equals 10 feet and the width equals 8 feet.

How to find the  length and width?

Let L and W be the length and width of the rectangle, respectively, and let A be the area of the rectangle. Then we have:

L = 10 ft (given)W = 8 ft (given)dL/dt = 5 ft/sec (length is increasing)dW/dt = -2 ft/sec (width is decreasing)

We want to find dA/dt, the rate of change of the area A with respect to time t, when L = 10 ft and W = 8 ft.

We know that:

A = L*W

Taking the derivative of both sides with respect to time t, we get:

dA/dt = d/dt (L*W)

Using the product rule of differentiation, we get:

dA/dt = dL/dt * W + L * dW/dt

Substituting the given values, we get:

dA/dt = 5 ft/sec * 8 ft + 10 ft * (-2 ft/sec)

Simplifying, we get:

dA/dt = 40 - 20 = 20 ft²/sec

Therefore, the area of the rectangle is changing at a rate of 20 ft^2/sec when the length equals 10 feet and the width equals 8 feet.

Josh wants to simplify the expression (-8)(10+(-5)+(-8))

Answers

Therefore, the simplified expression is 24.

To simplify the expression (-8)(10+(-5)+(-8)), you first need to solve the parentheses, following the order of operations, which requires solving the addition and subtraction within the parentheses before multiplying.

So, you have (-8)(10-5-8), which becomes (-8)(-3) after solving the parentheses. Finally, you can solve the multiplication by multiplying -8 by -3, resulting in 24.

It's important to remember the order of operations when simplifying expressions, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
