A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by th
Anni [7]

Answer: The rocket will reach its max after 4 seconds

Step-by-step explanation:

Hi, to find the maximum height, we have to set the first derivative of the equation equal to zero.

y=-16x^2+128x+136

0 = (2)-16x +128  

0= -32x+128

Solving for x:

32x = 128

x = 128/32

x = 4 seconds

The rocket will reach its max after 4 seconds

Feel free to ask for more if needed or if you did not understand something.

Solve the equation for x.
liq [111]

Answer:

x=55

Step-by-step explanation:

The given equation is \sqrt{x-6}+3=10

Group similar terms to get:

\sqrt{x-6}=10-3

\sqrt{x-6}=7

Square both sides to obtain:

x-6=7^2

x-6=49

Add 6 to both sides

x=49+6

Simplify the right hand side to obtain;

x=55
