Assuming this is a multiple choice question where the layout got lost:
√-72 = i√2*36 = 6i√2
This is the last answer in the list of options
Answer: 5%
Step-by-step explanation:
if it was 2.90 yesterday and 2.85 today there is a 5 cent decrease. to find the percent you convert .05 to a percent which is 5%
F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8
f^-1(4) = 2(4) - 8
f^-1(4) = 0
Answer:
g(a+b) = 3a² + 3b² - 6ab - 2a - 2b - 1
Step-by-step explanation:
<u>Given, function:</u>
<u>For the domain x= (a+b), the g(x) is:</u>
- g(a+b) = 3*(a+b)² - 2(a+b) - 1 = 3a² + 3b² - 6ab - 2a - 2b - 1
- g(a+b) = 3a² + 3b² - 6ab - 2a - 2b - 1
