Answer:

C)√ 72

Step-by-step explanation:

We will Simplify the radical by breaking the radicand up into a product of known factors.

When we do this, we figure out that...

A.√ 49 = 7

B.√ 64 = 8

D.√ 121 = 11

BUT C) is different.

√ 72 can not be divided into any whole number an exact amount of times.

So instead, this can be solved by writing it as shown:

Exact Form:

6 √ 2

Decimal Form:

8.48528137

Given:

Cost of 1 digital song = $1.05

Cost of 2 digital song = $2.10

Cost of 5 digital song = $5.25

To find:

The equation and the cost of 25 downloaded digital songs.

Solution:

Let us take two points (1, 1.05) and (2, 2.10).

Here $x_1=1, y_1=1.05, x_2=2, y_2=2.10$

Slope:

$$m=\frac{y_2-y_1}{x_2-x_1}$

$$m=\frac{2.10-1.05}{2-1}$

m = 1.05

Using point-slope formula:

$y-y_1=m(x-x_1)$

$y-1.05=1.05(x-1)$

$y-1.05=1.05x-1.05$

Add 1.05 on both sides, we get

$y=1.05x$

Here x is the independent variable and c is the dependent variable.

So that substitute x = n and y = c.

$c=1.05n$

The equation is c = 1.05 n.

Substitute n = 25 in the equation.

$c=1.05(25)$

$c=26.25$

The cost of 25 songs is $26.25.

A certain brand of coffee comes in two sizes. An 11.3-ounce package costs $2.54. A 27.8 ounce costs $6.78. Find the unit price f

Sauron [17]

Step-by-step explanation:

for the 11.3 ounce one:

1 ounce is $0.2247787611=$0.22

for the 27.8 ounce one:

1 ounce is $0.2438848921=$0.24

the 11.3 ounce one is a better buy as 1 ounce of it cost lesser than the 1 ounce of 27.8 ounce package.

Which equation represents the line that passes through (0,8)and(2,0)

Lelu [443]

The answer is C.

y= -4x + 8
You can plug in your coordinates.

For (0,8), plug in the x and y values.
8 = -4(0) +8
8 = 0+8
8=8 so, this works

For (2,0) plug in your coordinates.
y = -4x + 8
0 = -4(2) + 8
0 = -8 + 8
0=0

If both coordinates work for the equation, then they pass through that line.
