Answer:
The value of f(g(-2)) is 12.
Step-by-step explanation:
We'll start by solving g(-2):
Now we can take that value and plug it into function f:
Alternatively, you can work out a new single function that in itself describes f(g())
and try plugging -2 into the new function
Answer:
The answers are A, B, D, and F
Step-by-step explanation:
Correct on edge 2021!
Answer:
y² - (K- 2)y + 2k +1 = 0
equal roots means D=0
D= b^2 - 4ac
a=1, b= (k-2), c= 2k+1
so,
(k-2)^2 - 4(1)(2k+1) = 0
=> k^2 +4 - 8k -4 = 0
=> k^2 -8k = 0
=> k^2 = 8k
=> k= 8k/k
=> k = 8
Therefore the answer is k= 8

Answer:
176
Step-by-step explanation:
In order to find these kinds of problems, you need to divide the given number by the percentage in its decimal form.
25% = 0.25
