Answer: jacob is right
Step-by-step explanation:
each face in a cube is equal, and we know that there are six sides on a cube
this means that we need to find the surface area of one side and multiply it by six to see if jacob is correct
to find the area of one side you would do
a = Lw
a = 10 * 10
a = 100
so one face equals 100 cm^2 so 100 * 6 = 600
600 is less than 1000 so jacob is correct
The number of pretzels that must be sold to maximize the profit is 400.
<h3>What is the number of pretzels to be sold in the quadratic equation?</h3>
The number of pretzels to be sold can be determined by taking the derivative of the quadratic equation.
Given that:
P(x) = -4x^2+3200x-100
P'(x) = -8x + 3200
P''(x) = -8
At the critical point;
P'(x) = 0
Thus;
8x = 3200
x = 3200/8
x = 400
P''(400) = -8
P'' (400) < 0
Therefore, at x = 400, P(x) will be maximum.

Answer:
Annual sales of a particular electronic item in 2006 was 54.5 million.
Step-by-step explanation:
We have been given that s is the annual sales (in millions) for a particular electronic item. The value of s is 54.5 for 2006. We are asked to find the meaning.
Since s represent the annual sales (in millions) for a particular electronic item, therefore, means that annual sales of a particular electronic item in 2006 was 54.5 millions.
