<h2>Answer:</h2>

The reference angle for an angle whose measure is -440 is 80.

<h2>Step-by-step explanation:</h2>

Reference angle--

It is the angle which is made from the terminal side of the given angle and it is always made by taking x-axis as a reference.

Here we are given a angle whose measure is:

-440.

This means that the angle covers more than one rotation and ends in the fourth quadrant.

Hence, the reference angle is:

-440+360=80

Write an equation in point slope form for the line that passes through one of the following pairs of points. You may choose the

wolverine [178]

(5,1)(-3,4)
slope = (4 - 1) / (-3 - 5) = -3/8

y - y1 = m(x - x1)
slope(m) = -3/8
(5,1)...x1 = 5 and y1 = 1
now we sub
y - 1 = -3/8(x - 5) <=== point slope form

y - 1 = -3/8(x - 5)
y - 1 = -3/8x + 15/8
y = -3/8x + 15/8 + 1
y = -3/8x + 15/8 + 8/8
y = -3/8x + 23/8 <=== slope intercept form

y = -3/8x + 23/8
3/8x + y = 23/8 ...multiply everything by 8
3x + 8y = 23 <==== standard form

Find the inverse, picture below!

Setler79 [48]

Answer:

$f^{-1}(x) = (x+7)^2$

Step-by-step explanation:

$y=f(x) = \sqrt x - 7 \\\\\text{Replace x with y and then solve for y:}\\\\~~~~~~~~x= \sqrt y -7\\\\\implies \sqrt y = x+7\\\\\implies y = (x+7)^2\\\\\implies f^{-1}(x) = (x+7)^2$
