Answer:
![f(3) = 16](https://tex.z-dn.net/?f=f%283%29%20%3D%2016)
Step-by-step explanation:
<u>Step 1: Set x to 3
</u>
<u />![f(x) = x^2+7](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%2B7)
![f(3) = (3)^2 + 7](https://tex.z-dn.net/?f=f%283%29%20%3D%20%283%29%5E2%20%2B%207)
![f(3) = (9) + 7](https://tex.z-dn.net/?f=f%283%29%20%3D%20%289%29%20%2B%207)
![f(3) = 16](https://tex.z-dn.net/?f=f%283%29%20%3D%2016)
Answer: ![f(3) = 16](https://tex.z-dn.net/?f=f%283%29%20%3D%2016)
The equation for percent error is:
![|\frac{Experimental - Accepted}{Accepted}| * 100](https://tex.z-dn.net/?f=%7C%5Cfrac%7BExperimental%20-%20Accepted%7D%7BAccepted%7D%7C%20%2A%20100)
60 lb is the experimental and 68 lb is the accepted.
Plug in you values...
![| \frac{60-68}{68}| * 100](https://tex.z-dn.net/?f=%7C%20%5Cfrac%7B60-68%7D%7B68%7D%7C%20%2A%20100%20)
≈ 11.76 %
Answer:
<u>y = 3/2x + 6</u>
Step-by-step explanation:
<u>Equation of the given line</u>
- slope = rise/run = -2/3
- y-intercept = (0, -2)
- Equation is y = -2/3x - 2
<u>Perpendicular</u>
- Slope is the negative reciprocal
- m ⇒ -(1/[-2/3]) = 3/2
- Intersection point is (-2, 3)
<u>Using Point-slope equation</u>
- y - 3 = 3/2 (x + 2)
- y - 3 = 3/2x + 3
- <u>y = 3/2x + 6</u>
