Answer:
The time it takes them to grade the essays if they work together is 1.857 hours
Step-by-step explanation:
- Let t1 is time taken by Professor J = 3 hours
- Let t2 is time taken by the assistant = 5 hours
- Let tb is the time taken by both

Answer: linear
Step-by-step explanation:
V=(pi)r 2 h. ( volume is equal to pi times radius squared times height). V= pi 2^2 x8
Pi times 4times8= pi times 32. Put in a calculator pi times 32 and you get 100.5 cubic inches ( I haven’t done this in awhile but I think this is correct)
1)
Cosine = base / hypotenuse
Secant = hypotenuse / base = 1/Cosine
Sec = 1/(5/6) = 6/5
2)
Sine = perpendicular / hypotenuse = 5/6
hypotenuse² = base² + perpendicular²
base = √(6² - 5²)
base = √11
Cotangent = base / perpendicular
= √11/5
