Answer:

Segment A

Step-by-step explanation:

If you compare the speed to the distance using the graph, you can tell:

A) As the person travels, their speed increases

B) As the person travels, their speed does not change

C) As the person travels, the their speed decreases

Therefore, for the person's speed is increasing over segment A.

From an angle of depression of 61 degrees, John

meriva

Answer:

10.53

Step-by-step explanation:

Given :

Height of building = 17m

John's eye level = 2 m

Total height (including eye level) = 17+2 = 19m

Angle of depression, θ = 61°

Let distance between John's friend and building = d

Using trigonometry :

Tan θ = opposite / Adjacent

Tan 61° = 19 / d

1.8040477 = 19 / d

d = 19 / 1.8040477

d = 10.53

Suppose television networks raise the fees that cable television systems must pay to show their programs.

alina1380 [7]

Answer:

There might be less programs on there because it is more expensive to pay for. So maybe draw a graph with less programs than before.

Step-by-step explanation: This one was harder so it took me longer to think about it. I hope it's right

PLEASE HELP AS SOON AS POSSIBLE!!!!WILL GIVE BRAINLY TO CORRECT ANSWER!!!!

Mice21 [21]

Answer:

The correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.

Step-by-step explanation:

The circumference of table top = 24 $\pi$ inches

We need to find area of table top

The formula used to find area is: $Area = \pi r^2$

We need to find radius of tabletop.

The formula used to find circumference is: $Circumference = 2\pi r$

Putting value of circumference we can find radius

$Circumference = 2\pi r\\24\pi =2\pi r\\r=\frac{24\pi}{2\pi}\\r=12$

So, radius of table top = 12

Now, finding the area:

$Area = \pi r^2\\Area=\pi(12)^2\\Area=3.14(144)\\Area=452.16\:inches^2$

So, the correct option which best describes this method is:

Find half of 24 to calculate the radius. Then square the radius and multiply the result by $\pi$

Option D is correct option.
