If you would like to know who is the tallest, you can calculate this using the following steps:
Jackie ... j
Samuel: 5/8 inch + j = 5/8 + j = 0.625 + j
Shelly: 0.7 inch + j = 0.7 + j
Craig: 1/2 inch + j = 1/2 + j = 0.5 + j
The correct result would be: Shelly is the tallest.
Answer:
cross multiply and they should equal the same
Step-by-step explanation:
Answer:
Because theres nothing to solve for x is all real numbers
Step-by-step explanation:
There is no way to solve it as theres nothing to solve for. You just plug in the x's with any number you want and it still will be there
Answer:
t-shirts: 2790
profit: $12209
Step-by-step explanation:
Given the function:
p(x) = -x³ + 4x² + x
we want to maximize it.
The following criteria must be satisfied at the maximum:
dp/dx = 0
d²p/dx² < 0
dp/dx = -3x² + 8x + 1 = 0
Using quadratic formula:







d²p/dx² = -6x + 8
d²p/dx² at x = -0.12: -6(-0.12) + 8 = 8.72 > 0
d²p/dx² at x = 2.79: -6(2.79) + 8 = -8.74 < 0
Then, he should prints 2.79 thousands, that is, 2790 t-shirts to make maximum profits.
Replacing into profit equation:
p(x) = -(2.79)³ + 4(2.79)² + 2.79 = 12.209
that is, $12209
