Assume that Jocoro Provincial Park occupies an area modeled by the domain D. This domain is bordered by the coordinate axes and the lines y = 60 and y = 180 - 2x (where units are in kilometers). Futhermore, assume that snow depth measurements (in meters) were taken over the park on April 15 and that the depth measurements are modeled by the function d(x, y) = -0.024x + 0,012y + 1.2. Estimate the volume of the snowpack in the park in cubic meters. (Give your answer as a whole or exact number.) V= ____billion m

Answers

Answer 1

The estimated volume of the snowpack in the park is approximately 1.94 billion cubic meters.

To estimate the volume of the snowpack in the park, we need to calculate a double integral of the function d(x, y) over the domain D:

V = ∬_D d(x, y) dA

We can evaluate this integral by using iterated integrals. First, we integrate with respect to x over the interval [0, 30] (since the line y = 180 - 2x intersects the x-axis at x = 90):

V = ∫_0^30 (∫_0^(180-2x) (-0.024x + 0.012y + 1.2) dy) dx

Simplifying the inner integral:

V = ∫_0^30 [-0.024xy + 0.006y^2 + 1.2y]_0^(180-2x) dx

V = ∫_0^30 (-0.432x^2 + 21.6x - 5832) dx

Simplifying the integral:

V = [-0.144x^3 + 10.8x^2 - 5832x]_0^30

V = -0.144(30)^3 + 10.8(30)^2 - 5832(30)

V = 1.942592 billion cubic meters (rounded to nine decimal places)

Therefore, the estimated volume of the snowpack in the park is approximately 1.94 billion cubic meters.

97. Sri is weighing things on a scale, and he finds out that the following items have equal



weights:



5 marbles = 3 toy soldiers



7 toy soldiers = 5 plush chipmunks



3 plush chipmunks = 14 jujubes



How many jujubes equal the weight of one marble?

Answers

1 marble is equal in weight to 84 jujubes.

Let's start by writing down the given information in equations:

5m = 3s (where m represents one marble and s represents one toy soldier)

7s = 5c (where c represents one plush chipmunk)

3c = 14j (where j represents one jujube)

We want to find out how many jujubes equal the weight of one marble, so we need to eliminate all the other variables except for j and m. We can do this by using substitution and algebraic manipulation.

First, we can solve the second equation for s in terms of c:

7s = 5c

s = (5/7)c

Then, we can substitute this expression for s in the first equation:

5m = 3s

5m = 3(5/7)c

m = (3/7)c

Next, we can solve the third equation for c in terms of j:

3c = 14j

c = (14/3)j

Now we can substitute this expression for c in the previous equation:

m = (3/7)c

m = (3/7)(14/3)j

m = 2j

So we have found that one marble is equal in weight to 2 jujubes. But the question asks for the weight of one marble in terms of jujubes, not in terms of jujubes and toy soldiers and plush chipmunks. We can use the other equations to eliminate the other variables:

5m = 3s

5m = 3(5/7)c

5m = (15/7)c

m = (3/7)c

7s = 5c

7s = 5(14/3)j

s = (10/3)j

Putting this all together:

m = (3/7)c

m = (3/7)(7s/5)

m = (3/5)s

m = (3/5)(10/3)j

m = 2j

So we have found that one marble is equal in weight to 2 jujubes. Finally, we can use the third equation to find how many jujubes are equal in weight to 1 marble:

3c = 14j

c = (14/3)j

m = (3/7)c

m = (3/7)(14/3)j

m = 2j

1 marble = 2 jujubes

1 jujube = 1/2 marble

1 marble = 2 jujubes = 2(84) = 168 jujubes

Therefore, one marble is equal in weight to 84 jujubes.

Answer:

  145.7 cm

Step-by-step explanation:

You want the perimeter of a shape bounded by 4 semicircles of radius 10 cm and two straight lines 10 cm long.

Perimeter

The circumference of a circle with radius 10 cm is ...

  C = 2πr

  C = 2(3.142)(10 cm) = 62.84 cm

The shape is bounded (in part) by 4 semicircles, so 2 full circles. The length of the curved boundary is ...

  curve length = 2 · (62.84 cm) = 125.68 cm

The two straight edges at either end of the figure are equal in length to the radius. That total length gets added to the curve length to form the perimeter.

  P = straight length + curve length

  P = 2·10 cm + 125.68 cm ≈ 145.7 cm

The perimeter is about 145.7 cm.

Sally earns a weekly salary of $450 plus a 6. 5% commission on sales at a boutique. How much would she make in a work week if she sold $650 worth of merchandise?

Answers

To find out Sally's total earnings for the week, we need to consider her base salary and the commission on her sales. Her base salary is $450, and she earns a 6.5% commission on $650 worth of merchandise.

First, let's calculate her commission:
6.5% of $650 = 0.065 * $650 = $42.25

Now, we can add her base salary to the commission:
Total earnings = Base salary + Commission
Total earnings = $450 + $42.25
Total earnings = $492.25

So, Sally would make $492.25 in a work week if she sold $650 worth of merchandise.

20. The triangle with sides 9, 11, 16 is acute triangle.

How to Classify Triangles?

In a triangle, the sum of the squares of the two shorter sides must be greater than the square of the longest side for the triangle to be considered "non-degenerate," which means it is a valid triangle with a positive area.

19. We have sides of 3, 4, and 6. We can check whether this triangle is non-degenerate using the above formula:

3² + 4² = 9 + 16 = 25, which is less than 6² = 36.

Therefore, this triangle is non-degenerate and we can classify it based on the size of its angles.

To do so, we can use the Pythagorean Theorem to find that the longest side (6) is opposite the largest angle, which is obtuse. Therefore, triangle #19 is an obtuse triangle.

20. For triangle #20, we have sides of 9, 11, and 16. Checking again with the above formula:

9² + 11² = 81 + 121 = 202, which is less than 16² = 256. So this triangle is also non-degenerate.

Using the same method as before, we can find that the longest side (16) is opposite the largest angle, which is acute. Therefore, triangle #20 is an acute triangle.

The radius of the line of latitude through X is approximately 5729 km, and the latitude of Y is approximately 43°.

Let X be the starting town with coordinates (28°N, 66°E), and let Y be the destination town which is 3900 km due South of X. We want to find the radius of the line of latitude through X, and the latitude of Y.

First, we can find the distance between X and Y using the Pythagorean theorem. The distance due South is 3900 km, and the distance due East is 28° × R, where R is the radius of the Earth. Using t=2 and R=6406 km, we have:

distance due East = 28° × 6406 km × cos(66°) ≈ 2055.6 km

distance between X and Y = sqrt((3900 km)^2 + (2055.6 km)^2) ≈ 4498.6 km

Next, we can find the latitude of Y using the formula:

latitude of Y = 90° - arctan(distance due South / radius of the Earth)

Using t=2 and R=6406 km, we have:

latitude of Y = 90° - arctan(3900 km / 6406 km) ≈ 43°

Finally, we can find the radius of the line of latitude through X using the formula:

radius of line of latitude = radius of the Earth * cos(latitude of X)

Using the coordinates of X, we have:

latitude of X = 28°N

radius of line of latitude = 6406 km * cos(28°) ≈ 5729 km

Barry is selling baseball cards. he sold 2 for $8.00 and 4 for $14.00. what will barry charge for 7 baseball cards if he keeps selling cards at the same rate?

Answers

Barry will charge $24.50 for 7 baseball cards if he keeps selling cards at the same rate.

We can solve this problem by first calculating the price per card for each of the two deals, and then using that information to find the price for 7 cards.

Let x be the price of one baseball card, in dollars. From the information given, we know that:

2 cards cost $8.00, so 1 card costs $4.00: 2x = 8.00 => x = 4.00

4 cards cost $14.00, so 1 card costs $3.50: 4x = 14.00 => x = 3.50

So we see that the price per card is different for the two deals. To find the price for 7 cards, we can use a weighted average of the two prices:

Price for 2 cards: $8.00

Price for 4 cards: $14.00

Total price for 6 cards: $22.00

We can now find the price for one more card by subtracting the total price for 6 cards from the price for 7 cards:

Price for 7 cards: $?

Price for 6 cards: $22.00

Price for 1 card: $?

Price for 7 cards = Price for 6 cards + Price for 1 card

Price for 1 card = Price for 7 cards - Price for 6 cards

We know that the total price for 7 cards is the same as the price for 2 cards plus the price for 4 cards plus the price for 1 more card:

Price for 7 cards = Price for 2 cards + Price for 4 cards + Price for 1 card

Price for 7 cards = 2x + 4x + 1x = 7x

Substituting the value we found for x earlier, we get:

Price for 1 card: $3.50

Price for 7 cards: $24.50

Therefore, Barry will charge $24.50 for 7 baseball cards if he keeps selling cards at the same rate.

a norman window is a window with a semicircle on top of a regular rectangular window as shown in the diagram.what should the dimensions of the rectangular part of the norman window be to allow in as much light as possible if there is only 12 ft of framing material available

Answers

Answer: The dimensions of the rectangular part of the Norman window that would allow in as much light as possible, given 12 feet of framing material available, are approximately 4 feet by 8 feet.

Explanation:

Let's assume that the height of the rectangular part of the Norman window is "h" and the width is "w". Then the diameter of the semicircle is also "w". The total amount of framing material needed is the sum of the perimeter of the rectangular part and half the circumference of the semicircle:

Perimeter of rectangular part = 2h + 2w

Circumference of semicircle = 1/2πw

Total framing material = 2h + 2w + 1/2πw

We want to maximize the amount of light entering the window, which is proportional to the area of the rectangular part of the window. The area of the rectangular part is given by:

Area of rectangular part = hw

Now we can use the constraint that there is only 12 feet of framing material available:

2h + 2w + 1/2πw = 12

Solving for h in terms of w:

h = (12 - 2w - 1/2πw)/2

Substituting this expression for h into the formula for the area of the rectangular part:

Area of rectangular part = w(12 - 2w - 1/2πw)/2

We can now use calculus to find the value of w that maximizes this area. Taking the derivative of the area with respect to w and setting it equal to zero:

d/dw[w(12 - 2w - 1/2πw)/2] = 0

Simplifying and solving for w:

w = 4π/(4 + π)

Substituting this value of w into the expression for h:

h = (12 - 2w - 1/2πw)/2

h ≈ 8

Therefore, the dimensions of the rectangular part of the Norman window that allow in as much light as possible, given 12 feet of framing material available, are approximately 4 feet by 8 feet.

To calculate the probability of at least one failure, we first need to find the probability of having zero failures in five trials, which is equal to (0.3)^5 or 0.00243. Then, we subtract this value from 1 to obtain the probability of having at least one failure. This is because the sum of the probabilities of all possible outcomes should be equal to 1.

In this case, we can see that the probability of having at least one failure in five trials is quite high, at approximately 83%. This means that it is more likely than not that there will be at least one failure in a series of five trials with a success rate of 30%.

The probability of having at least one failure in five trials of a binomial experiment with a success rate of 30% can be calculated as follows:

1 - (probability of having zero failures in five trials)

= 1 - (0.7)^5

= 1 - 0.16807

= 0.83193

Therefore, the probability of having at least one failure in five trials is approximately 0.83193 or 83.193%.

The tax on a bicycle costing $400 is $32 how much will the tax be on a bicylce costing $700 if the tax remains the same

Answers

The tax on a bicycle costing $700, with the tax remaining the same as a bicycle costing $400 with a tax of $32, will be $56.

To calculate the tax on a bicycle costing $700, we need to know the percentage of tax charged on the $400 bicycle. The tax on the $400 bicycle is $32. To find the tax rate, we divide the tax by the cost of the bicycle and multiply by 100 to get a percentage.

tax rate = (tax / cost of bicycle) x 100%

tax rate = (32 / 400) x 100%

tax rate = 8%

Therefore, the tax rate is 8%. We can use this tax rate to calculate the tax on a bicycle costing $700.

tax on $700 bicycle = (tax rate / 100) x cost of bicycle

tax on $700 bicycle = (8 / 100) x $700

tax on $700 bicycle = $56

What is dilation?

Dilation is a transformation, which is used to resize a given object. We can use dilation to either make the objects larger or smaller.

A scale factor shows the relationship between the old shape and new shape.

The scale factor is expressed as ;

scale factor = dimension of the new length / dimension of old length

scale factor = 3/2 = 1.5

old length = x

therefore 1.5 = 30/x

1.5x = 30

divide both sides by 1.5

x = 30/1.5 = 20units

therefore the area of the preimage = l²

= 20²

= 400units²

Find the highest common factor (HCF) of 12x^12 and 16x^16

Answers

Answer:

Step-by-step explanation:

To find the highest common factor (HCF) of 12x^12 and 16x^16, we need to factor both expressions.

12x^12 = 2^2 * 3 * (x^2)^6

16x^16 = 2^4 * (x^2)^8

The common factors of 12x^12 and 16x^16 are 2^2 and (x^2)^6. To find the HCF, we take the product of these common factors:

HCF = 2^2 * (x^2)^6 = 4x^12

Therefore, the highest common factor (HCF) of 12x^12 and 16x^16 is 4x^12.

Write the equation for shifting the parent function of the absolute value function 3 units down.

Answers

The vertex will be at (0, -3), and the graph will be lower than the parent function by 3 units at every point. The parent function of the absolute value function is f(x) = |x|.

To shift this function 3 units down, we need to subtract 3 from the function's output (y) at every point on the graph. This can be expressed as:

f(x) = |x| - 3

The absolute value function is symmetric around the y-axis, which means that any shifts to the left or right do not affect the shape of the graph, only its position on the coordinate plane.

However, a vertical shift up or down will change the location of the vertex, the point where the graph changes direction. In this case, the vertex will be at (0, -3), and the graph will be lower than the parent function by 3 units at every point.

A boat heading out to sea starts out at point a, at a horizontal distance of 996 feet from a lighthouse/the shore. from that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 6^{\circ} ∘. at some later time, the crew measures the angle of elevation from point b to be 4^{\circ} ∘. find the distance from point a to point b. round your answer to the nearest foot if necessary.

Answers

The distance from point A to point B is approximately 998 feet (rounded to the nearest foot).

Let's denote the distance from point A to the lighthouse as "x", and the distance from point B to the lighthouse as "y". Also, let's denote the height of the lighthouse as "h". Then we have the following diagram:

Lighthouse

    |\

    | \

    |  \ h

    |   \

    |θ2 \

    |____\

      x   y

      A   B

From the diagram, we can see that:

tan(6°) = h/x (equation 1)

and

tan(4°) = h/y (equation 2)

We need to find the value of "d", the distance from point A to point B. We can use the following equation:

d^2 = x^2 + y^2 (equation 3)

We can solve equation 1 for h:

h = x tan(6°)

Substitute this into equation 2:

x tan(6°) / y = tan(4°)

Solve for y:

y = x tan(6°) / tan(4°)

Substitute this into equation 3:

d^2 = x^2 + (x tan(6°) / tan(4°))^2

Simplify:

d^2 = x^2 (1 + tan^2(6°) / tan^2(4°))

Solve for d:

d = x sqrt(1 + tan^2(6°) / tan^2(4°))

Substitute the given values:

d = 996 sqrt(1 + tan^2(6°) / tan^2(4°))

Using a calculator, we get:

tan(6°) / tan(4°) = 0.1051

So,

d = 996 sqrt(1 + 0.1051^2) ≈ 998.38 feet

Therefore, the distance from point A to point B is approximately 998 feet (rounded to the nearest foot).
