Find the length of the arc<br> A.8 pie ft<br> B.32 pie ft<br> C.64 pie ft<br> D. 361 pie/ 12 ft
ExtremeBDS [4]
<h3>Answer: Choice A. 8pi  feet</h3>

======================================================

Explanation:

The perimeter around the circle is known as the circumference

The full circumference of a circle with radius r is

C = 2*pi*r

In this case, r = 16 is the radius, so,

C = 2*pi*r

C = 2*pi*16

C = 2*16*pi

C = 32pi

is the full distance around the circle. But we only want 90/360 = 1/4 of that total distance. So take 1/4 of 32pi to get

(1/4)*32pi = (1/4*32)pi = 8pi

The arc length is exactly 8pi feet long

Approximately this is about 25.13274 feet

Select the correct answer. Evaluate the following expression when x = -4 and y = 4. A. B. C. D.
andriy [413]

The value of given expression when x=-4 and y=4 is 1250.

The expression is missing in the question which is \dfrac{x^6-x}{4y}.

We have to solve it for x= -4 and y = 4.

Now putting the value of x and y we get,

\dfrac{x^6-x}{4y}=\dfrac{(-4)^6-(-4)}{4}

\dfrac{x^6-x}{4y}=\dfrac{4096+4}{4}

\dfrac{x^6-x}{4y}=1250

Hence the value of given expression when x=-4 and y=4 is 1250.

Stephen and Diana are traveling towards each other from points that are 276 miles apart. If Diana is traveling 4 mph faster than
Allisa [31]

Answer:

Step-by-step explanation:

let speed of Stephen=x mph

speed of Diana=x+4

then

6x+6(x+4)=276

divide by 6

x+x+4=276/6=46

2x=46-4=42

x=42/2=21

Stephen is traveling at  21 mph.

Diana is traveling at 21+4=25 mph.
