Answer:

7=x/5; she has earned 35 points

Step-by-step explanation:

(5)7=x/5(5)

so, you multiply each side by five, since the inverse operation of division is multiplication, then solve.

7(5)=35

x/5(5)=x

so x (the number of points she earned) is equal to 35.

Which of the following trigonometric ratios has a value that is undefined?

34kurt

Answer:

csc π.

Step-by-step explanation:

csc π because csc = hypotenuse / opposite side and the opposite side = 0. Anything divided by zero is undefined.

Another way to the same conclusion is: we know that sin π = 0 and csc π = 1 / sin π = 1 / 0 which is indeterminate.
