Answer:
B: Each runner varies with respect to multiple variables. Each runner should use both models to account for their individual differences. This will provide an accurate comparison for the difference in wear between the models.
Step-by-step explanation:
Since the shoe company wants to test the wear of the shoes after two months, it means that option B will be the most accurate.
This because everybody has peculiarities in the bodies and also running patterns. These could have an effect on either of their legs. Thus, having to wear a new one on one leg and the original one on another leg for a month and then replacing with the second leg of both for the other month would be the best way to know the true effect of wear on the shoes because they have both been subject to same conditions within exactly the same timeframe.
Answer:
4) 33.51 cu.in
5) 84.82 cu.m
7) 2.09 cu.ft
8) 1047.197 cu.cm (CC)
11) 163.62 cu.in
Step-by-step explanation:
Volume is h/3x πr^3
4) 4/3 x π x 2^3 = 33.51
5) 3/3 x π x 3^3 = 84.82
7) 2/3 x π x 1^3 = 2.09
8) 8/3 x π x 5^3 = 1047.197
11) 10/3 x π x 2.5^3 = 163.62
Answer:
225 m²
Step-by-step explanation:
If W is the width of the rectangle, and L is the length, then:
60 = 2W + 2L
A = WL
Use the first equation to solve for one of the variables:
30 = W + L
L = 30 − W
Substitute into the second equation:
A = W (30 − W)
A = 30W − W²
This is a parabola, so we can find the vertex using the formula x = -b/(2a).
W = -30 / (2 × -1)
W = 15
Or, we can use calculus:
dA/dW = 30 − 2W
0 = 30 − 2W
W = 15
Solving for L:
L = 30 − W
L = 15
So the maximum area is:
A = WL
A = (15)(15)
A = 225
As far as I can see, it should be 5/10 is parrots which is simplified into 1/2 .
Hope this helps!
