Answer:
The answer to your question is y - 0 = 40(x - 15)
Step-by-step explanation:
y = 40x + 600
Convert to y - y₁ = m(x - x₁)
Process
1.- Factor 40 in the right side of the equation
y = 40(x - 15)
2.- Give the form of the point slope form
y - 0 = 40(x - 15)
where
y₁ = 0
m = 40
x₁ = 15
Answer:
21 kWh
Step-by-step explanation:
1. Subtract 25% from the original amount.
25% of 28 kWh is ...
0.25 × 28 kWh = 7.00 kWh
Subtracting this from 28 kWh, we find the usage after reduction to be ...
28 kWh - 7 kWh = 21 kWh
__
2. We know that if we reduce 100% of a quantity by 25%, then the resulting amount is (100 -25)% = 75% of the original. As a fraction, this is 75/100 = 3/4 of the original amount. Then the reduced usage is ...
(3/4) × (28 kWh) = 3·(7·4)/4 kWh = 3·7 kWh = 21 kWh
__
Mario must reduce his usage to 21 kWh or less.
Angle of depression = 12.52°
The right angle triangle formed has a height of 200 ft and a base of 900 ft.
The opposite side of the triangle is 200 ft while the adjacent side of the triangle is 900 ft.
Using tangential ratio we can find the angle of depression. Therefore,
Let
x = angle of depression
tan x = opposite/adjacent
opposite = 200 ft
adjacent = 900 ft
tan x = 200/900
tan x = 2/9
x = tan⁻¹ 2/9
x = tan⁻¹ 0.222
x = 12.5166739144
x = 12.52°

Answer:
Multiply 60 by .40
60 * .40 = 24
Answer is B
Step-by-step explanation:
Answer is: "A"
Formula used:
V = 4/3πr^3
we already know r so
V = 4/3(π)13^3
