8 pens are red because you have to subtract 23 from 15
Answer: 4
===================================
Rule: The geometric mean of two numbers x and y is sqrt(x*y)
In this case, x = 2 and y = 8
So we have the geometric mean equal to sqrt(2*8) = sqrt(16) = 4
If you wanted to find the geometric mean of three values, then you'll multiply the numbers and take a cube root. If you had four values, then you multiply and apply a fourth root. And so on.
the answer that is equal to 1/4 is 2/8 3/12 and 4/16
Answer:
1/2
Step-by-step explanation:
Answer:
f (g(2)) − g(f (−1)) = -5
Step-by-step explanation:
Find the value for each term:
1. f (g(2)): g(2) is 4, so we get f(4), which is = -3
2. g(f (−1)): f(-1) is -1, so we get g(-1), which is = -2
Now we can write:
f (g(2)) − g(f (−1))
-3 -2
= - 5
