The equation h = -16t 2+ 53x + 8 gives the height h, in feet, of a football as a function of time t, in seconds, after it is kic
Elanso [62]

Answer: The maximum height the football reaches = 51.89 feet.

Step-by-step explanation:

Given: The equation h = -16t^2+ 53t + 8 gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked.

Differentiate the given equation, we get

h'=-(2)16t+53=-32t+53   (i)

Put h'=0

\Rightarrow\ -32t+53=0\\\\\Rightarrow\ t=\dfrac{53}{32}\approx1.65625

Differentiate (i) w.r.t. t, we get

h''=-32 < 0  i.e. h is maximum at t= 1.65625

The value of h at t= 1.65625 will be -16(1.65625)^2+53(1.65625)+8=51.890625\approx51.89\text{ feet}

Hence, the maximum height the football reaches = 51.89 feet.

What’s the answer and can somebody explain how to solve it
inessss [21]

The area of a trapezoid is calculated using the formula: 1/2(a + b)h. The diagram shows that base number one (a) is 8.5 dm and base number two (b) is 26.5 dm. The height is 9 dm. Substitute these values into the formula.

1/2(8.5 + 26.5) * 9, add 8.5 and 26.5 inside the parentheses.

1/2(35) * 9, you can now solve from left to right. Multiply 1/2 and 35.

17.5 * 9, multiply to get your final answer. The area of the trapezoid is C. 157.5 dm^2.
