Answer:
The equation is true
Step-by-step explanation:
First, input -4 instead of m in the equation:
5(-4 - 1) = -25
Then, distribute:
-20 - 5 = -25
Finally, simplify:
-25 = -25
This equation is true, and that's how you prove it.
Hope this helps!
Answer:
Compound interest the interest changes annually and with simple interest the interest is the same annually
tangent(angle) = Opposite Leg ( Height) / Adjacent Leg ( base)
Tangent(56.3) = Opposite Leg / 48 feet
Opposite Leg = 48 x tangent(56.3) = 71.97
Height = 72 feet ( rounded to the nearest foot).
Step One
Find the area of the base
A = s * s
s = 755.5 feet
Area = 755.5^2
Area = 570780.25 square feet.
Step two
Multiply the volume by 3
V = 1/3 B * h
3*V = B * h
V = 85600000
85600000 * 3 = B * h
256800000 = B * h
Step Three
Divide by B
B = 570780.25
256800000 = 570780.25 * h
256800000 / 570780.25 = h
449.91 feet = h
To find slope, we must find the change in y values divided by the change in x values, also called the rise/run. This is modeled below:
Slope = m = (y1 - y2)/(x1-x2) = (6-(-3))/(1 - (-6)) = (6+3)/(1+6) = 9/7
We can check that this answer is correct by consulting the graph. The graph shows a positive correlation (means that the slope should be positive), and if you count the graph unit squares, you get that the graph moves up 9 squares and over 7 squares between the two points shown, letting us know we got the right answer.
Hope this helps!
