Answer:

B

Step-by-step explanation:

the arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{90}{360}

     = 2π × 16 × \frac{1}{4}

     = 32π × \frac{1}{4}

     = \frac{32\pi }{4}

     = 8π ft

If a rectangle has a length of 5in, a width of 4in, and a height of 8in.Evaluate the volume using the formula: V=LWH 20 inches c
ozzi

Substitute the numbers in the equation:

V=LWH

Since L=5in, W=4in and H=8in:

\begin{gathered} V=(5in)(4in)(8in) \\ =160in^3 \end{gathered}

Therefore, the volume is equal to 160 inches cubed.

Answer:

slope = \frac{5}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 4) ← 2 points on the line

m = \frac{4+1}{2-0} = \frac{5}{2}

An Impressionist painting increases in value
jok3333 [9.3K]

Answer:

A = $8406.6

Step-by-step explanation:

Given:

Average rate r=9\%

Initial cost of painting a = \$1500

Time t = 20\ years

We need to find the final amount of painting at the end of a 20-year.

Solution:

Using Exponential Growth rate formula as:

A = a(1+r)^t  ----------(1)

Where:

A = Final amount

a = Initial amount.

r = Rate as a decimal.

t = Time.

Now, we substitute all given values in equation 1.

A = 1500(1+0.09)^{20}

A = 1500(1.09)^{20}

Substitute 1.09^{20} = 5.60 in above equation.

A = 1500\times 5.60

A = $8406.62

Therefore, value of the  painting at the end of  a 20-year A = $8406.6
