Answer:
d. y+8=2(x-4)
Step-by-step explanation:
There are 2 important parts to this question. First, understanding which slopes are perpendicular. The negative reciprocal of a number will be perpendicular to it. So, since the original slope is -1/2 the new slope should be 2.
Then, remember what the point-slope formula is. The point-slope formula is: 
. So if you plug in the point and slope the new equation looks like, 
. Then, simplify for the final answer of 
.

<span>2. A pool company is trying out several new drains. Drain A empties a pool at a rate of 2 gal/min. Drain B empties a pool at a rate of 5 gal/min. One pool has 108 gal of water in it. Write an equation for each drain that shows the amount of time it takes to empty the pool. Then solve each equation showing your work.</span>
Drain A: rate is 2 gal/min. We do not know which pool has 108 gallons of water in it. If it's Pool A, then the time required to empty Pool A is
108 gallons
------------------- = 54 minutes
2 gallons/min
If it's Pool B, then we can represent the amount of water in Pool B by b. Then the time required to empty Pool B is
b (gallons)
------------------ = (b/5) minutes
5 gallons/min
48,100,000,000,000 in scientific notation is 4.81E+13.
tan 52 = 180/a; a = 180/tan 52
tan 43 = 180/b; b = 180/tan 43
you need to calculate, a-b = 180/tan 52 - 180/tan 43
substitute the value of tan thetas, and calculate it simply...
