cosR =
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR = = =

Answer:
y=4x-8. y=4x−8 y = 4 x -
Step-by-step explanation:
I think is it
The correct answer is is D) If the group sells 15 prints they will loose $85.
To figure out which statement is true, we have to evaluate the function ,
for all the values given in options (A)-(D). A negative output represents a loss and a positive output will represent a profit.
In A so . In this case we gather that if they sell 12 prints, they will make a loss of $136. This tells us that option A is wrong.
In B, so . In this case we gather that if they sell 28 prints, they make a profit of $136. This tells us that option B is wrong.
In C, so . In this case we gather that if they sell 35 prints, they make a profit of $225. This tells us that option C is wrong.
Lastly, so . In this case we gather that if they sell 28 prints, they make a loss of 85 dollars. From this we gather that D is the correct option.
