A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t) = 52t - 16t^2 . What i
Nata [24]

Answer: 42.25 feet

Step-by-step explanation:

We know that after "t" seconds, its height "h" in feet is given by this function:

h(t) = 52t -16t^2

The maximum height is the y-coordinate of the vertex of the parabola. Then, we can use the following formula to find the corresponding value of "t" (which is the x-coordinate of the vertex):

x=t=\frac{-b}{2a}

In this case:

a=-16\\b=52

Substituting values, we get :

t=\frac{-52}{2(-16)}\\\\t=1.625

Substituting this value into the function to find the maximum height the ball will reach, we get:

h(1.625) = 52(1.625) -16(1.625)^2\\\\h(1.625) =42.25\ ft

What is the power of 10 when 75,200 is written in scientific notation?
andreyandreev [35.5K]
<u>The correct answer</u> is:
4.

Explanation:
In scientific notation, we place the decimal behind the first non-zero digit in the number.  For 75,200, this is 7.  

We then count the number of places we must move the decimal to place it here.  In this problem, we move the decimal 4 places.  This is the exponent for 10.
