Answer: Find the area of the base A = πr² Then multiply by height to get the volume.

Then divide the volume ___ft³ by the rate given.

Step-by-step explanation: Since this is an "Initial Knowledge Check" you are not expected to know everything. ALEKS will give you instruction and practice on the topics where you need to learn more. It's OK to get some of these wrong now so you'll have a chance to demonstrate how much more you have learned in a few weeks.

Flura [38]

Answer:

B The cost, in dollars, for each additional gigabyte used.

Step-by-step explanation:

C = 59 + 15(g − 5)

when g=5, C=59 where it is the monthly cost

when g=6, c=59 +15, interpret that each additional gigabyte used will increase the cost for 15

write the slope intercept form of an equation of the line that passes through (4,3) that is perpendicular to the line Y=-3x-15

cricket20 [7]

If two lines are perpendicular, then their slopes have a product of -1 or you could say they are opposite signed reciprocals of each other.
The given equation has a slope of -3. We know this because it is in slope-intercept form y = mx + b ...y = (slope)x + (y-intercept).

so taking the slope -3...the opposite signed reciprocal would be + $\frac{1}{3}$

Now we have a slope and a point... we can use them to find the b (y-intercept)
x = 4, y = 3, and m = $\frac{1}{3}$
$3= \frac{1}{3} (4)+b$
$3= \frac{4}{3} +b$
Using the common denominator fraction for 3, we subtract 4/3 from both sides
$3= \frac{9}{3}$
$\frac{5}{3} =b$
plug the values for m and b into the slope intercept form
$y= \frac{1}{3} x+ \frac{5}{3}$
