timofeeve [1]

Answer:

<u>Height of the cylinder = 15</u>

98 pts to correct answer! CALCULUS BC Trig Substitution (SEE Attached)
storchak [24]

Answer:

A

Step-by-step explanation:

Let x = Tan(\theta)

dx = sec²(\theta)d(\theta)

sqrt(1 + Tan^2(\theta) ) = sec(\theta)

So I = Tan(theta) * sec(theta)

but Tan(theta) = sin(theta) / cos(theta) = sin(theta)*sec(theta)

So I = integral sin(theta)*sec^2(theta) d theta

Answer A

For every car you sell, you get a 6% commission. IF your total sales for the month is $125,650, what is your commission?
Lera25 [3.4K]
Let
x= total cost of cars
y= total commission paid out for all cars sold

6%= 6/100 = .06

Set up an equation:
y= .06(x)

Given: x= $125,650

substitute into the y= .06(x)

multiply $125,650 by .06.

The answers would be: 7539
