1. The answer would be about 20.72, or 20.7142 if you don’t want the rounded version
2. The answer is -12.8
The value of W when V = 9 is 405
<h3>How to solve for W?</h3>
The variation is a direct variation from W to V^2.
This means that:
W = kV^2
Where k is the constant of variation.
W = 320 when V = 8 means that:
320 = k * 8^2
Evaluate
320 = 64k
Divide both sides by 64
k = 5
Substitute k = 5 in W = kV^2
W = 5V^2
When V = 9, we have:
W = 5 * 9^2
Evaluate
W = 405
Hence, the value of W when V = 9 is 405

Answer:
-3 ≤ f(x) ≤ 6
Step-by-step explanation:
The minimum value of the function on that range is -3; the maximum value is 6.
The range of f(x) on the given domain is [-3, 6].
Answer:
Step-by-step explanation:
I do not understand 0:2 in this formule: (x) = 3x^2- 0:2x^5+ 7x?
Does that mean 0:2=0??
