You can just insert 1, 4, and 10 for n.

A(1) = -2 + (1 - 1) * (-2.2) = -2
A(4) = -2 + (4 - 1) * (-2.2) = -8.6
A(10) = -2 + (10 - 1) * (-2.2) = -21.8

How to solve???????????
Soloha48 [4]

Answer:

$70.88

Step-by-step explanation:

To find sales tax, multiply the price by the percentage as a decimal.

$67.50                         67.50(0.05) = $3.38

Since sales tax is 5%, its decimal equivalent is 0.05 and for the price of $67.50 you pay $3.38.

The total amount paid is the price added to the sales tax.

$67.50 + 3.38 = $70.88

Repeat these steps for each price in the sales amount column.

You have a wire that is 38 cm long. You wish to cut it into two pieces. One piece will be bent into the shape of a square. The o
Drupady [299]

Answer:16.71 cm

Step-by-step explanation:

Given

Length of wire L=38 cm

One piece is bent in the form of square and another in the form of circle

let x be the length of circle

therefore length of square side \frac{38-x}{4}

A=total area of square and circle

radius of circle r=\frac{x}{2\pi }

area of circle A_c=\pi r^2=\pi \times (\frac{x}{2\pi })^2

Area of square A_s=(\frac{38-x}{4})^2

A=\pi \times (\frac{x}{2\pi })^2+(\frac{38-x}{4})^2

To get the minimum value of A we get

\frac{\mathrm{d} A}{\mathrm{d} x}=\frac{2x}{4\pi }-\frac{2(38-x)}{16}

\frac{\mathrm{d} A}{\mathrm{d} x}=0

\frac{x}{4\pi }=\frac{38-x}{16}

x=\frac{38\pi }{4+\pi }

Therefore circumference of circle

x=\frac{38\pi }{4+\pi }=\frac{119.396}{7.142}=16.717 cm
