Answer:
3.8s
Step-by-step explanation:
Solve for h=0, you will get t=3.75
If
, then
and
because
lies in the fourth quadrant.
By DeMoivre's theorem,

so the answer is B.
There are two ways to approach this.
Option #1:
Use the slope formula
.

That value is undefined, so the slope is undefined.
Option #2:
Because the two points have the same x-value, they will be vertically above/below one another. This means your line is a vertical line and the slope of a vertical line is undefined.
Either way, your slope is undefined.
4 legged tables : x
3 legged stools : y
x + y = 20 y= 20 - x
4x + 3y = 68
Replace y by 20 - x so we only have one letter
4x + 3(20 - x) =68
4x + 60 - 3x =68
x + 60 = 68
x = 8
To find y replace x by 8
y = 20 - 8
y = 12
So you have 8 four legged chairs and 12 three legged stools.

Answer:
55 1/8 in. squared
Step-by-step explanation:
Area = L*W
3 1/2 * 1 3/4 = 6 1/8
because there are 9 planters we multiply 6 1/8 by 9 and you would get 55 1/8 in. squared
in. is for inches
