A bouncing ball reaches a height of 54 inches at its first peak, 36 inches at its second peak, and 24 inches at its third peak.

sesenic [268]

Answer:

f(x) = 54(two-thirds) Superscript x minus 1

Step-by-step explanation:

Given that:

First peak : 36 / 54=2/3

Second peak : 24 / 36 = 2/3

The common ratio here is 2/3 ; which mean each bounce height is 2/3 of previous height

Modeling this using geometric progression :

An=a1r^(n-1)

An = nth term of a geometric progression

a1=first term

r=common ratio = 2/3

n = nth term

a1=54

Substituting into the above formular :

An=54(2/3)^(n-1)

What is the area of a trapezoid that has the bases of 1 1/4ft and 14 inches and a height of 3 inches.

Rom4ik [11]

The area of the trapezoid is 43.5 inches²

Step-by-step explanation:

The formula of the area of a trapezoid is $A=\frac{1}{2}(b_{1}+b_{2})h$ , where:

$b_{1}$ and $b_{2}$ are the two parallel bases
h is its height

∵ $b_{1}$ = $1\frac{1}{4}$ feet

∵ $b_{2}$ = 14 inches

∵ h = 3 inches

- Change the length of $b_{1}$ from feet to inches

∵ 1 foot = 12 inches

∴ $1\frac{1}{4}$ feet = $1\frac{1}{4}$ × 12 = 15 inches

∴ $b_{1}$ = 15 inches

Substitute the values of $b_{1}$ , $b_{2}$ and h in the

formula of the area

∴ $A=\frac{1}{2}(15+14)(3)$

∴ A = 43.5 inches²

The area of the trapezoid is 43.5 inches²
