Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

1 answer:

4 0

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

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