Answer:

g(h(-8)) = 119

Step-by-step explanation:

Given

  • g(x)=2x-5
  • h(x)=x²-2

To determine

  • g(h(-8)) = ?

In order to determine g(h(-8)), we need to determine h(-8) first

substituting x = -8 in h(x)=x²-2

h(-8) = (-8)² - 2

h(-8) = 64 - 2

h(-8) = 62

so

g(h(-8)) = g(62)

now substituting x = 62 in g(x)=2x-5

g(62)=2(62)-5

g(62) = 124 - 5

g(62) = 119

so

g(h(-8)) = g(62) = 119

Therefore,

  • g(h(-8)) = 119

3/4 of 80 is 60.
so we know that out of 100, 60 have long brown hair. 
in simplest fraction form, 60/100= 3/5

KengaRu [80]

Answer:

\frac{1}{25}

Step-by-step explanation:

Using the rule of exponents

a^{-m} = \frac{1}{a^{m} }, hence

f(- 2) = 5^{-2} = \frac{1}{5^{2} } = \frac{1}{25}
