Answer:
18 feet long.
Step-by-step explanation:
Let the bottom section be x feet long, then:
x/6 + x/2 + x = 180
Multiply through by 6:
x + 3x + 6x = 1080
10x = 1080
x = 108 feet,
So the top section = 108/6
= 18 feet long.
Answer:
Step-by-step explanation:
Your equation makes no sense.
I will ASSUME you mean
y = -x² - 2x + 3
which can be factored
y = (x + 3)(-x + 1)
x intercepts occur when y = 0
0 = (x + 3)(-x + 1)
which means either
x + 3 = 0
x = -3
or
-x + 1 = 0
x = 1
x intercepts are (-3, 0) and (1, 0)
The vertex will occur halfway between these point
x = (-3 + 1) / 2 = -1
so vertex = y = -(-1)² - 2(-1) + 3 = 4
(-1, 4)
Answer:
Goal = x
45000 = 9/10 * x
x = 45000 * 10/9 = 50000
Step-by-step explanation:
You may find something useful on my you tube channel "Sciency Sergei". You may also suggest a topic to discuss or problems to solve.
The y intercept is 3 because that is where the point aligns to the axis
