-78 since they are both negative you just add them
5 h
_ = _
10 28
You would cross multiply and get 140=10h and you divide both sides by 10 and get 14=h. So the flagpole is 14 feet tall.
Answer:
If you have choices it is either -5 or 5.
Step-by-step explanation:
First, you find two points, which mine were (0,2) and (-1,7). The slope formula is y2 - y1 divided by x2 - x1. So, im going to subtract 7 - 2, which is your y2 - y1, to get 5. Then, i'm going to subtract -1 - 0, which is your x2 - x1, to get -1. Then, you divide 5 by -1 to get -5. I Hope This Helps :)
<span>2In4x= 2In8
ln(16x^2) = ln64
Multiply e by both sides.
16x^2 = 64
Divide both sides by 16
x^2 = 4
Take the square root of both sides.
x = 2</span>
Answer:
1,620 square inches
Step-by-step explanation:
The area of one triangle can be computed using the formula ...
A = 1/2bh . . . . where b represents the base length, h represents height
A = 1/2(18 in)(36 in) = 324 in²
Then the area of 5 flags will be 5 times that much:
fabric needed = 5 × (324 in²) = 1,620 in²
Brian will need 1,620 square inches of fabric for his 5 triangular flags.
