Seyla raced her horse 3 times around a circular track with a radius of 180 yards. How many yards did they travel?

The answer would be 3392.92006588 yards. The formula for circumference of a circle is C=2πr so it would be 180 x 2 which is 360 then multiply that by pi which is 1130.97335529 and then you would multiply that by 3 to find the total which is 3392.92006588

Use circumference formula which is c=2 times pi times radius

c=2 times pi times radius

radius=180
c=2 times 180 times pi
c=360 times pi
pi is aprox 3.14 so
c=360 times 3.14=1130.4 yards
that's one lap so multiply by 3
360π times 3=1080π
1130.4 times 3=3391.2
the answer is 1080π yards or 3391.2 yards

Answer:

after 21 seconds

Step-by-step explanation:

Given

h = - 16t² + 272t + 1344

When the ball strikes the ground then h = 0, that is

- 16t² + 272t + 1344 = 0 ( divide through by - 16 )

t² - 17t - 84 = 0 ← in standard form

(t - 21)(t + 4) = 0 ← in factored form

Equate each factor to zero and solve for t

t - 21 = 0 ⇒ t = 21

t + 4 = 0 ⇒ t = - 4

However t > 0 thus t = 21

The ball strikes the ground after 21 seconds.

Graph the funtion f(x) = <img src="https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%20-%202%7D" id="TexFormula1" title="\sqrt[3]{x - 2

This process is very simple. All you are doing is creating a table of values somewhere to help you graph this function. As you can see, the coordinates of $\displaystyle [-6, -2], [1, -1], [2, 0], [3, 1],$ and $[10, 2]$ are all touched on this graph, letting you know that this information is accurate.
