The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2
A. 14.43
13.36x0.08 = 1.068
13.36+1.068 = 14.428 (round up) 14.43
The resistance is proportional to the length.
You know that 45/9=5
So the ratio (proportionality) is 5.
So, for a 75 ft wire, the resistance is 75/5 = 15 ohms
The function is open up for both since the stretch value is positive. When opening you we don’t have a maximum value only a minimum value. So already we know B and d are wrong. When looking at minimums and maximums we look at the y or q value. In this case for f(x) it is 4 and for g(x) it is 5. So we know g(x) have a greater minimum value, so the answer is c
