Answer:
y = - 5/6 x + 1
Step-by-step explanation:
y = mx + b m: slope b: y intercept
point (6 , -4) x = 6 y = -4
b = y - mx = -4 - ((-5/6) x 6) = - 4 + 5 = 1
equation: y = - 5/6 x + 1
Given:
The local rate for electrical service is 6 cents per kilowatt-hour.
We need to know how much money would be saved in a year by using a dishwasher 4times per week rather than 6 times per week
From the table:
The cost of using a dishwasher 4 times per week = $29
The cost of using a dishwasher 6 times per week = $44
So, the saving will be = 44 - 29 = 15
So, the answer will be $15
F(x) = -x² + 4
f(3) = -3² + 4
f(3) = -9 +4
f(3) = -5
Answer:
Step-by-step explanation:
From the given right angle triangle,
The unknown side represents the hypotenuse of the right angle triangle.
With m∠40 as the reference angle,
x represents the adjacent side of the right angle triangle.
4 represents the opposite side of the right angle triangle.
To determine x, we would apply
the Tangent trigonometric ratio.
Sin θ = opposite side/hypotenuse. Therefore,
Tan 40 = 4/x
x = 4/Tan 40 = 4/0.839
x = 4.8
Answer:
$55.13
Step-by-step explanation:
50 * 1.05 = 52.5
<em>We do this step twice because the interest is for </em><em>2 years.</em>
52.5 * 1.05 = 55.125
<em>This rounds up to 55.13, your final answer!</em>
