a rectangular pool has an area of 640 square feet. the is 12 feet shorter than the width. the length of the pool is feet and the
Ray Of Light [21]

Given:

Area of rectangular pool = 640 square feet

The length is 12 feet shorter than the width.

To find:

The length and width of the pool.

Solution:

Let width of the pool = x feet

Then, Length of the pool = (x-12) feet

Area of a rectangle is

Area=length\times width

Area=(x-12)\times x

Area of pool is 640 square feet. So,

(x-12)x=640

x^2-12x-640=0

Splitting the middle term, we get

x^2-32x+20x-640=0

x(x-32)+20(x-32)=0

(x+20)(x-32)=0

Using zero product property, we get

x=-20,32

Dimensions cannot be negative. So, x=32.

Now,

Width of the pool = 32 feet

Length of the pool = 32-12 = 20 feet

Therefore, the length of the pool is 20 feet and width is 32 feet.

A golf ball is hit with an initial velocity of 64 Ft/s. The function h(t) = -16t^2 + 64t models the height h (in feet) of the go
Arlecino [84]

Answer:

  • Yes, the ball reaches the height of 64 ft

Step-by-step explanation:

<u>Given function</u>

  • h(t) = -16t^2 + 64t

<u>The maximum value is at vertex and the x-value of the vertex is:</u>

  • t = -64/2(-16) = 2

<u>Finding the maximum height the ball can reach:</u>

  • h(2) = -16(2²) + 64(2) = -64 + 128 = 64

The answer is yes
