I have a question about this please see attachment

Answer:

I think it is 4275cm square.

Answer:

Area= 4275cm

Step-by-step explanation:

The area formula for a rectangle is length x width so if we plug in the numbers and multiply we get 4275 as our product.

Answer:

I think you are intended to pick A as your answer. But D is a thorn. The question especially D is not worded accurately.

Step-by-step explanation:

Remark

I take it that you are asked what the relationship between a and b is. What you can say is that a and b are a linear pair if a and be have 1 leg on a ray. I will treat it that way, but you should always question whether that is true or not.

Solution

Adjacent Math meaning: Each angle has a common side and a common point where they meet. A and B are adjacent: True.

Linear Pair. True A and B are adjacent angles and they are also supplementary. So C and E are both true.

That makes D incorrect.

Answer:

[tex]\huge\purple{ x^2 +(y+2)^2 = 4}[/tex]

Step-by-step explanation:

Circle is centred at (0, -2)

-> h = 0 & k = - 2

radius of the circle (r) = y-coordinate of the center = - 2

Equation of circle in standard form is given as:

[tex](x-h)^2 +(y-k)^2 = r^2[/tex]

Plugging the values of h, k and r in the above equation, we find:

[tex](x-0)^2 +[y-(-2)]^2 = (-2)^2[/tex]

[tex]\implies\huge\orange{ x^2 +(y+2)^2 = 4}[/tex]

This is the required equation of circle.

Answer:

56 minute 40 seconds

Explanation:

unit rate: 6 meters per minute

The elevator starts from 20 m below ground level.

So, in total have to cover distance = 20 + 320 = 340 meter

Time taken = distance/speed

                   = 340/6

                   = 56.67 minute

                   ≈ 56 minute 40 seconds

Answer:

5.88*10^12

Step-by-step explanation:

You have to move the decimal place over 12 times and to the left, so it's positive.

It's not clear what is under the square root. Is it solely the x only?

In other words, is the equation this: [tex]y = \sqrt{x}+5[/tex] ?

If so, then the range is y≥5 because y = 5 is the smallest possible output. In other words, we can have y = 5 or y > 5. I recommend using a tool like Desmos to graph and verify.

-----

OR is the +5 also under the square root?

Is the equation this? [tex]y = \sqrt{x+5}[/tex]

If so, then the range would be y≥0

The smallest output possible of a square root function is 0. We cannot get negative outputs. This explains how y = 0 is the smallest output. So y = 0 or y > 0, or in short, y≥0

The solution is, the range of the function y=√x+5 is y∈(∞,∞) is Range, from the given options y≥0.

The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

here, we have,

we know that,

Range of a function is defined as those values of y, for which x is Defined.

The given function is

y=√x+5

Squaring both sides

we get,

y² = x+5

or, x = y²- 5

x is defined for ,all Real values of y.

For any real y,we get defined value of x.

That is , y ∈ R

→→y∈(-∞,∞)⇒Range

Hence, The solution is, the range of the function y=√x+5 is y∈(∞,∞) is Range, from the given options y≥0.

The experimental (aka empirical) probability for your friend is 1/500 = 0.002 since she hit the bulls eye once out of 500 tries. This is a 0.2% chance.

To calculate the theoretical probability, we have to determine the area of each circle:

A = smaller circle area = pi*r^2 = pi*(0.25)^2 = 0.0625pi

B = larger circle area = pi*r^2 = pi*6^2 = 36pi

Divide A and B to get the theoretical probability

A/B = (0.0625pi)/(36pi) = 1/576 = 0.0017 approximately

This is fairly close to the 1/500 = 0.002 your friend got, which in my opinion means that her result is expected. She does seem a bit more skilled than expected since she managed to hit the bulls eye in 76 fewer tries (576-500 = 76). However, I would stick to the "result is expected" answer, since problems like this tend to have variability.

The sum of -4 + 3i and -2 - i implies that we plot -6 on the real side, and 2i on the imaginary side of the complex plane

The complex numbers are given as:

-4 + 3i and -2 - i

The sum of these numbers is represented as:

Sum = -4 + 3i -2 - i

Collect the like terms

Sum = -4  -2 + 3i - i

Evaluate the like terms

Sum = -6 + 2i

The above means that we plot -6 on the real side, and 2i on the imaginary side of the complex plane

If both printers work together. Then the number of the pamphlets will be 20x in four hours.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

A local print shop has a big order of pamphlets to print, so they decide to use two of their printers for the one job.

The newest printer can print the pamphlets four times as fast as the old printer Working together the printers can complete the job in 4 hours.

Let x be the number of the pamphlets are printed by the old printer in one hour.

Then the number of the pamphlets are printed by the new printer in one hour will be 4x.

Then if they work together, then the  number of the pamphlets in one hour will be 5x.

Then the number of the pamphlets in 4 hour will be

→ 5x × 4

→ 20x

Step-by-step explanation:

Discussion

The first thing you have to do is convert km to miles

Formula

1 mile = 1.6 km

x mile = 40000 km              Cross Multiply

Solution

1.6*x = 1 * 40000                  Divide by 1.6

x = 40000/1.6

x = 25000 miles

Answer Part 1

The distance covered is 25000 miles

Discussion Part 2

That's the distance covered in a day. Now we need to convert that to speed. The time (in hours) for 1 day is 24 hours.

Givens

d = 25000 miles

t = 24 hours

s = ?

Solution

s = d/t

s = 25000 / 24

s = 1041.66 miles per hour

Answer:

D. quadrant III

Step-by-step explanation:

Given that the particle is in equilibrium, the value of p = 2.5 and the value of q = -1.5

To answer the question, we need to know what force are

A force that thing which cause a change in motion of an object

Since there are three forces (15i + j) N, (5qi – pj) N and (-3pi - qj) N, where p and q are constants, act on a particle. Given that the particle is in equilibrium, the resultant force on the particle is zero.

A resultant force is a vector sum of two or more forces

So,  (15i + j) N + (5qi – pj) N + (-3pi - qj) N = 0i + 0j

15i + 5qi - 3pi + j - pj - qj = 0i + 0j

(15 + 5q - 3p)i + (1 - p - q)j = 0i + 0j

Equating components, we have

15 + 5q - 3p = 0 and 1 - p - q = 0

5q - 3p = -15 (1) and - p - q = -1

5q - 3p = -15 (1) and p + q = 1 (2)

From equation (2), p = 1 - q (3).

Substituting p into (1), we have

5q - 3p = -15 (1)

5q - 3(1 - q) = -15

5q - 3 + 3q = -15

5q + 3q = -15 + 3

8q = -12

q = -12/8

q = -3/2

q = - 1.5

Substituing q into (3), we have

p = 1 - q

p = 1 - (-3/2)

p = 1 + 3/2

p = (2 + 3)/2

p = 5/2

p = 2.5

So, the value of p = 2.5 and the value of q = -1.5

Answer: [tex]x < 8\\[/tex]

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Interval Notation: (-∞, 8)

The equivalent inequality to 5(2x-6)+6(3-x)<2x+4 is x < 8.

Let's simplify the given inequality step by step:

Original inequality: 5(2x - 6) + 6(3 - x) < 2x + 4

Distribute the constants inside the parentheses:

10x - 30 + 18 - 6x < 2x + 4

Combine like terms on the left side:

(10x - 6x) - 30 + 18 < 2x + 4

4x - 12 < 2x + 4

Subtract 2x from both sides to isolate the x terms on the left side:

4x - 2x - 12 < 4

Simplify:

2x - 12 < 4

Now, add 12 to both sides:

2x - 12 + 12 < 4 + 12

2x < 16

Finally, divide both sides by 2:

2x / 2 < 16 / 2

x < 8
