Answer:
108 cubic feet
Step-by-step explanation:
Multipy Base, height, and width.=
4 3/5 ≈ 5
1 1/5 ≈ 1
(4 3/5) +(1 1/5)
≈ 5 +1
≈ 6 . . . . . . . . . . . the estimated sum rounded to whole numbers
_____
Additional information:
As a refinement to your estimate, you can estimate the error. The first number is 2/5 less than 5. The second number is 1/5 more than 1, so the errors add up to
.. (2/5) +(-1/5) = 1/5
That is, your "estimate" of 6 is actually too high by 1/5. You can refine that estimated value by subtracting 1/5. 5 4/5 would be a closer "estimate."
The
<u>correct answer</u> is:
The relationship is linear, and the equation is
y-5 = 2(x+7).
Explanation:
To determine if the relationship is linear, we find the slope between each pair of points. Slope is given by the formula:
The slope between the <u>first two points</u> is given by:
The slope between the <u>second pair of points</u> is given by:
The slope between the <u>third pair of points</u> is given by:
Since the <u>slope is the same</u> throughout the data, the <u>relationship is linear</u> and the slope is 2.
To write the equation, we use point-slope form, which is:
y-y₁ = m(x-x₁)
Using the first point, we have:
y-5 = 2(x--7)
y-5 = 2(x+7)
Total up the number calls that each point suggests(y coordinates).
0+2+5+9+4+3+9+6+2+0 = 40 calls
I think there is a rule based in there, so Like:
T^1 : (x , y) ------> (x+3 , y+1)
T^2: (x, y ) -------> (x +3 +3 , y+1+1) = (x+6, y+2)
So I think T^3 should be:
T^3: (x, y) -------> ( x+3+3+3 , y+1+1+1) = (x+9, y+3)
So the answer should be the 2nd.
