10 is 8% of a, and 5 is 4% of b. c equals b/a. What is the value of c?? step by step explanation pls...

c = 1

Step-by-step explanation:

"10 is 8% of a":     0.08a = 10, or a = (10/0.08)

"5 is 4% of b":      0.04b =  5, or b = (5/0.04)

"c equals b/a":       c = (b/a)

What is the value of c?

c = (b/a)

c = ((5/0.04)/(10/0.08))

c = (5/0.04)*(0.08/10)

c = (5/10)*(0.08/0.04)

c = (1/2)*(2)

c = 1

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

depends what are you allowed to do ?
