Answer:
2A /h -b =p
If you need it with a common denominator
(2A -bh)/h = p
Step-by-step explanation:
A = 1/2 ( p+b)h
Multiply each side by 2
2A = ( p+b)h
Divide by h
2A/h = ( p+b)h/h
2A/h = ( p+b)
Subtract b
2A/h -b = p+b -b
2A /h -b =p
If you need it with a common denominator
(2A -bh)/h = p
Answer:
A) 24 ways
B) 4 ways
Step-by-step explanation:
a) permutation occurrs when order of choices matters.
N = 4P3 = 4!/(4-3)! = 4!/1!
N = 24 ways
b) combination occurs when order of choices doesn't matter.
N = 4C3 = 4!/3!(4-3)! = 4!/3!(1!)
N = 4 ways
Assuming that b(x) = sqrt(x-4), then (b o a)(x) = sqrt [ (3x+1) - 4 ]
3x+1-4, the input to function b(x), MUST be ≥ 0. Therefore, 3x - 3 ≥ 0, or
3(x-1) ≥ 0, or x ≥ 1 (answer)
