Answer:
it's the 3rd option
Step-by-step explanation:
f(x) 0 over the intervals (–∞ –3)
Hope it's right
f(5) = <span> -2(5)^2 + 2(5) -3
f(5) = -50 + 10 - 3
f(5) = -43

15 to 2 is a 7.5 ratio so 3 to 22.5 is a 7.5 ratio so the mural would be 22.5 feet long.
Hope that helps.
Answer:
a = 54
Step-by-step explanation:
In geometry, the angles in a triangle add up to 180.
The unmarked angle at the top of the triangle = 180 - (a+10+44)
Or you could say that same angle = 180 - 2a because it is supplementary to the exterior angle... so
2a = a + 10 + 44
2a-a = 54
a = 54
Answer:
a) 9 ways.
b) 6 ways.
Step-by-step explanation:
We know that there are three different routes connecting city A to city B.
We calclulate how many ways can a round trip be made from A to B and back. We conclude that the exists 3·3 = 9 ways.
We calclulate how many ways can a trip be made from A to B if it is desired to take a different route on the way back. We conclude that the exists
3·2 = 6 ways.
