Answer:
y = -1/4x - 10
Step-by-step explanation:
<em>Hey there!</em>
<em />
Well to the slopes of 2 perpendicular lines are reciprocals of each other meaning if the line has a slope of 4 then it’s perpendicular line has a slope of -1/4.
Now to find the y intercept we need to graph,
y = -1/4x and point (4, -11)
Look at the image below.
By looking at the image below we can tell that in order for the perpendicular line to go through point (4,-11) it would be -10.
The equation is y = -1/4x - 10

Answer: 16 square inches</h3>
Explanation:
Apply the cube root to 64 to get ![\sqrt[3]{64} = 64^{1/3} = 4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%20%3D%2064%5E%7B1%2F3%7D%20%3D%204)
The exponent 1/3 is handy if your calculator doesn't have a cube root button.
This wooden cube has side lengths of 4 inches each.
Each square face will have an area of 4^2 = 4*4 = 16 square inches.

i.e 3.017watts
Answer:
8n³ + 10n² - 13n - 15
Step-by-step explanation:
Distribute the factors by multiplying each term in the first factor by each term in the second factor, that is
4n(2n² + 5n + 3) - 5(2n² + 5n + 3) ← distribute both parenthesis
= 8n³ + 20n² + 12n - 10n² - 25n - 15 ← collect like terms
= 8n³ + 10n² - 13n - 15
