The answer is cot² ∅ - csc² ∅ = -1

Referring to Pythagorean identities: 
sin² ∅ + cos² ∅ = 1
1+cot² ∅ = csc² ∅
tan² ∅ + 1 = sec² ∅

1+cot² ∅ = csc² ∅  
⇒ transposing 1 and csc² ∅ we will have now
cot² ∅ - csc² ∅ = -1

Answer:

C) The cost increases $2.50 for every additional pair of shoes rented.

Step-by-step explanation:

Notice a pattern. When you buy a new pair of shoes, the total gets increased by $2.50 depending on how many pairs of shoes you buy. For example, starting with 1 pair of shoes, it costs $2.50, but when you buy another pair, the cost is $2.50+$2.50=2*$2.50=$5.00, and so on...

Therefore, the correct choice is C

It takes Emma 3/4 minutes to ride her bike a distance of 1/8 miles. What is Emma's average speed in miles per minute?
sp2606 [1]

Answer:

The answer is 1/6

Step-by-step explanation:

1/8 miles in 3/4 minutes

then, that means in 1 minute ( 1 min = 3/4 * 4/3) Emma will ride a distance of (1/8)*(4/3)= (1*4)/(8*3)= 1/6.

The answer is 1/6 (in 1 min she will ride 1/6 miles).

Hope that useful for you.
