You can see that every time you increase x by 2, the correspondent y value is increased by 7.

This is the behavior of linear function: the ratio between changes in x and y values, the so-called "rise over run" ratio, is constant.

Hope this helps?

Please help me... Question is in the picture

Butoxors [25]

Ok so as it says, the equation for the circumference (C) is C=2(pi)r.
Pi is about 3.14, so all you have to do is multiply those three values together for the circumference.
C=2•3.14•4
C= 25.12

So the answer would be D, 25.12.

(03.03 MC) The table below represents a linear function f(x) and the equation represents a function g(x): x f(x) −1 −6 0 −3 1 0

kaheart [24]

The function g(x) has a greater slope and the function f(x) has a greater y-intercept

<h3>How to compare the slopes?</h3>

The function is given as:

Function f(x)

x f(x)

-1 -6

0 -3

1 0

g(x) = 4x - 5

The slope of f(x) is calculated using:

$m = \frac{f(1) - f(0)}{1 -0}$

This gives

$m = \frac{0 + 3}{1 -0}$

Evaluate

m = 3

By the general format of a linear equation, the slope of the function g(x) is:

m = 4

4 is greater than 3

Hence, the function g(x) has a greater slope

<h3>How to compare the y-intercepts?</h3>

This is when x = 0

For the function f(x), we have:

f(0) = -3

For the function g(x), we have:

g(0) = 5-

-3 is greater than -5

Hence, the function f(x) has a greater y-intercept

Need help! Law of cosines...find b round to the nearest tenth please

dusya [7]

ANSWER

$B = 27.8 \degree$

EXPLANATION

The law of cosine is given by the formula:

${b}^{2} = {a}^{2} + {c}^{2} - 2bc \cos(B)$

From the diagram,

a=17, b=8, c=16

We substitute the given values into the formula to obtain:

${8}^{2} = {17}^{2} + {16}^{2} - 2(17)(16)\cos(B)$

$64 = 289+ 256- 544\cos(B)$

$64 = 545- 544\cos(B)$

$64 - 545 = - 544\cos(B)$

$- 481 = - 544\cos(B)$

$\frac{ - 481}{ - 544} = \cos(B)$

$cos(B) = 0.88419$

$B = \cos ^{ - 1} (0.88419)$

$B = 27.8 \degree$
