Question A model rocket is launched at time t = 0 from the top of a hill with a height of 60 feet. The formula h(t) = -3t^2+12t+

60 gives the rocket's height after t seconds.
Write an equivalent form of the equation to revel the maximum height of the rocket.

Requirements You must use both a graph and an algebraic method in your solution Somewhere in your explanation, you need to "complete the square" to create your equivalent method and find the height of the rocket.

What other angle between O and 360 degrees has the same TAN value as 71
atroni [7]

Answer:

<u>-289 degrees</u>

Step-by-step explanation:

You are looking for what is called  <u>Coterminal Angles</u>.

To find a coterminal angle between 0 and 360 you <u>add or subtract</u> 360.

  1. In this case, we subtracted 360 from 71
  2. 71 - 360 = -289
  3. tan(-289) = 2.90
  4. If  TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.

Hope this helps!! Please mark Brainliest!!!

What is the equation of exponential regression equation? Round all numbers you your answer to three decimal places
ExtremeBDS [4]

Given:

The given values are:

a=0.2094539899

b=2.507467975

r^2=0.9435996398

r=0.9713905701

To find:

The exponential regression equation for the given values (Rounded to three decimal places).

Solution:

The general form of exponential regression equation is:

y=a\cdot b^x          ...(i)

Where, a is the initial value and b is the growth/decay factor.

We have,

a=0.2094539899

b=2.507467975

Round these numbers to three decimal places.

a\approx 0.209

b\approx 2.507

Substitute a=0.209, b=2.507 in (i) to find the exponential regression equation.

\hat{y}=0.209\cdot 2.507^x

Therefore, the correct option is C.
