First u do a squared +b squared =c squared aka pythagorean theorem then so u already have c squared so you would do 5x5=25 and 13x13=169 so then the equation would be 25+?=169 then do 169-25 which equals 144 and then do the square root of that which is 12 THE ANSWER IS 12

Answer:

c. 1 $\frac{3}{8}$ inches

Step-by-step explanation:

Since the paper clip is past the 1, the answer will be 1 and ___.

the mark in the middle of the 1 and 2 is one half (1/2)

the mark in between the 1 and 1/2 is 1/4

the mark between 1/4 and 1/2 is 1/8

there are three (3) 1/8 marks where the paperclip is

3 * 1/8 = 3/8

so your answer is 1 3/8

hope this helps:)

If c(x) = 4x – 2 and d(x) = x2 + 5x, what is (cd)(x)?

ludmilkaskok [199]

Answer: cd(x) = 4x³ — 2x² + 8x — 4

Step-by-step explanation:

c(x) = 4x - 2

d(x) = x² + 2

Therefore, cd(x) = c(x) × d(x)

cd(x) = (4x - 2)(x² + 2)

= (4x × x²) + (4x × 2) + (-2 × x²) + (-2 × 2)

= 4x³ + 8x -2x² - 4

cd(x) = 4x³ — 2x² + 8x — 4

Hope this helps?

Answer:

The table shows a proportional relationship: YES

The constant of proportionality is k=7

y = 7x

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y = kx

Where k is the constant of proportionality. It can be calculated by solving the equation for k:

$\displaystyle k=\frac{y}{x}$

We are given a table with 4 pairs of values. If the relationship between the variables is proportional, then the ratio y/x should be constant.

Let's verify some points:

$\displaystyle k=\frac{63}{9}=7$

$\displaystyle k=\frac{28}{4}=7$

$\displaystyle k=\frac{14}{2}=7$

$\displaystyle k=\frac{77}{11}=7$

Since all the ratios are equal,

The table shows a proportional relationship: YES

The constant of proportionality is k=7

The equation for the relationship is

y = 7x
