A golf ball is manufactured so that if it is dropped from A feet above the ground onto a hard surface, the maximum height of eac

Lunna [17]

Step-by-step explanation:

a.) To model this scenario

Let the height of ball = y

The height of 1st= 0.5y

2nd =0.5(0.5y)

3rd = 0.5*(0.5(0.5y))

Hence the height of nth bounce can be modeled as

Height of nth bounce =(0.5ⁿ-1)*y

The exponential equation is

hn= (0.5ⁿ-1)*y

b.) if the ball is dropped from 9ft above the ground

y= 9ft

On the 4th bounce

n=4

Substituting in the exponential equation we have

h4=(0.5^4-1)*9

h4=0.5³*9

h4= 0.125*9

h4= 1.125ft

On the 4th bounce, the ball will reach a height of 1.125ft

A farmer plants corn in 1/4 of his field. He plants white corn in 3/5 of the corn

bija089 [108]

Answer:

$\frac{3}{20}$

Step-by-step explanation:

Fraction of the total that is for corn (TC - Total corn):

$TC=\frac{1}{4}$

fraction of the corn section that is for white corn (WC - white corn in the corn seccion):

$WC=\frac{3}{5}$

we need to find the fraction of the whole field that is for the white corn.

For this we need to find how much is $\frac{3}{5}$ out of the $\frac{1}{4}$ destinated to corn, and this will be the fraction of the total that is for white corn. We find this fraction by multiplying the fraction of corn ( $\frac{1}{4}$ ) by the fraction of white corn in the corn section ( $\frac{3}{5}$ ).
