Answer:
ft^2
Step-by-step explanation:
Here in this question, we have a farmer who wants to purchase the correct amount of paint, but needs to know the surface area of the barn. We now need to select the correct unit in which the farmer would have his surface area.
In other words, what the question is simply asking us is to select which of the given units would serve as the appropriate unit for the surface area of the barn.
Mathematically, when we talk about area, we are simply talking about multiplying the length of a side with the length of another side.
We know the barn is not a single shape but shaped in terms of different segments which have different area and can be added together to give the total surface area of the barn.
Now, like we said above, we are multiplying a length by the length of another side, no matter the type of shape we are considering.
What this means is that our power( index) won’t be more than 2 since we can only multiply two sides of a particular length at a time.
So the option that would give the correct answer would be the option which has its power raised to the power of two.
The only option that fits the criterion is the last option which is the ft^2 and this in fact is the correct answer
Answer:
In order of increasing slope:
B: y = 0
A: y = 2x-3
C: y = 3x+1
Step-by-step explanation:
(3,3), (5,7), and (6,9) are points on line A.
Use the coordinates of two of the points to find the slope of A.
Δy =7-9 = -2
Δx =5-6 = -1
Slope = Δy/Δx = 2
Equation for line of slope 2 that passes through (3,3):
y-3 = 2(x-3)
y = 2x-3
(3,0) and (5,0) are points on line B. They are horizontally aligned, so the equation for line B is y=0. Slope = 0.
You were given the equation for C: y = 3x+1. Slope = 3
In order of increasing slope:
B: y = 0
A: y = 2x-3
C: y = 3x+1
Uh, about 50m high, because the pole's height is half that of the shadow, and there is no further info provided, so it is logical to conclude that the same can work for the building as well.
