Suppose that 5 people sitting in a enclosed room are each generating about 500 BTUs of body heat per hour. If the room is 10 ft x 15 ft x 10 ft, how many BTUs per cubic foot do they produce in 3 hours?
A) 5 BTUs/t3
B) 8 BTUs/ft3 C) 11 BTUs/ft3
D) 14 BTUs/ft3

How do you find principle and simple interest

Find the zeros of each function. f(x) = x^2 + 5x - 6

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection
