<u>Answer</u>
18.5 m²
<u>Explanation</u>
The figure is a sector of angle 85° and of radius 5 m.
The area = θ/360 × π × r²
= 85/360 × 3.14 × 5²
= 18.5347
The answer to one decimal place is 18.5 m²
X^2-18 = 3x
x^2 - 3x - 18 = 0
(x-6)(x+3) = 0
x = {-3,6}
So -3 is the answer
Answer:
(-3,-6) and (-3,2)
Step-by-step explanation:
A line with an undefined slope is vertical. In this case it must have x coordinates equal to -3
Answer:
74
Step-by-step explanation:
You subtract 43 from 12 you get 31 then you add 43 and 31 you get 74 bye
Parallel: the lines have = slopes. We thus need 5/6 to equal 2/p. then 5p must equal 12, and p = 12/5. (answer)
Check: Is 5/6 = 2 / (12/5)? YES
Perp.: The lines have slopes that are negative reciprocals of one another.
Then -6/5 = 2/p, or
-6 2
---- = ----
5 p Thus, -6p = 10, and p = -5/3 (answer)
