Answer:
Slope is positive.
Every additional hat produced results in a cost increase of $0.60
Before producing any hats the cost is about $100
Step-by-step explanation:
Calculate the slope or rate of change using two data points from the table.
This means that the cost rises by $6 for every 10 hats or 0.60 per 1 hat. The slope is positive and increasing.
This also means that for 0 hats the cost is 105-6 = 99 or about $100.

Answer:
64.62°
Step-by-step explanation:
Use good 'ol SOHCAHTOA. Since we know the hypotenuse and the adjacent values, we use cosine.
Therefore:
Take the inverse cosine of each side:
Inverse cosine of cosine cancel each other out:
Use a calculator:
Therefore the angle is 64.62°
To find the inverse we have to first change the function notation to 'y'
So
f(x) = -x becomes y = -x
Next, we have to switch the x and y values
So, y = -x becomes x = -y
Now, we have to solve for y.
y = -x
So the inverse of f(x) = -x is:
So
f(x) = -x becomes y = -x
Next, we have to switch the x and y values
So, y = -x becomes x = -y
Now, we have to solve for y.
y = -x
So the inverse of f(x) = -x is:
