Answer:
She earned 11 after completing 5 chores
Step-by-step explanation:
<em>We are shown a scatter plot and the equation of best fit line. The eqaution explains the general trend of the scatterplot. Using the equation we can find the money earned for 5 chores</em>
Amount of money earned, y = 2x + 1 ---(1)
Chores Completed, x = 5
put x = 5 in eq(1)
y = 2(5) + 1
y = 11
The value of the cosine of angle 
is 1.
Given a point 
that is a terminal arm of an angle in standard position, by trigonometric relations we have the following expression for the cosine:
(1)
Where:
- - Angle measure, in sexagesimal degrees.
- Horizontal position of the point of the terminal arm, no unit.
- Vertical position of the point of the terminal arm, no unit.
If we know that 
and 
, then the cosine of the angle is:
The value of the cosine of angle is 1.

Answer:
The inverse is 1/2x +2
Step-by-step explanation:
f(x) = 2x-4
y= 2x-4
To find the inverse
Exchange x and y
x = 2y-4
Solve for y
Add 4 to each side
x+4 = 2y
Divide by 2
x/2 + 4/2 = 2y/2
1/2x +2 = y
The inverse is 1/2x +2
