write a slope intercept equation for a line passing through the point (2,-2) that is parallel and perpendicular to the line x=-1
vekshin1

You would need two different lines to complete this as lines cannot be both parallel and perpendicular (these are opposites). The answers would be:

Parallel: x = 2

Perpendicular: y = -2

In order to find these, we first need to see that the original line of x = -1 is a horizontal line. Therefore, any line that is parallel should be horizontal as well. To get a horizontal line through the point (2, -2), the only option is x = 2.

Similarly, with the perpendicular line, if the original line is horizontal, the new line must be vertical. The only vertical line that goes through (2, -2) is y = -2.

the diameter of a cone-shaped container is 4 inches, and its height is 6 inches .How much grater is the volume of a cylinder-sha
sveticcg [70]
The radius r used in below equations would equal 2in because it is half the given diameter of 4in.
The volume of the cone would be 
V = \frac{1}{3}  \pi r^2h \\ \\ V = \frac{1}{3} \pi (2in)^2(6in) = 8 \pi\ in^3

The volume of a cylinder with the same dimensions would be
V =  \pi r^2h \\ &#10;V =  \pi (2in)^2(6in) =  24 \pi in^3

The cylinder is 24 - 8 = 16 cubic inches greater.

Someone please answer and explain!!!
emmainna [20.7K]
Hi there! The answer is B. $ 11,323.38

To find our answer we need to fill in the formula with the given data:

t = 5
P (the initial value) = $9000
I = 4.7% / 100 = 0.047 (since we have to change the percentage into a multiplier).

Now just fill in:
a(5) = 9000 \times (1.047 ){}^{5}  = 11323.375...
Rounded, our answer is B. $11,323.38
