First do the the parenthesis: (6-3) = 3

Now you have [-4 + 3 * 8] -10

Next do multiplication: 3 *8 = 24

Now you have [-4 + 24]-10

Now do what is in brackets: -4 + 24 = 20

Now you have 20-10

Subtract 20-10 = 10

A prism is created using 2 regular pentagons as bases. The apothem of each pentagon is 2.8 centimeters. Which expression represe
mash [69]
Recall that the volume of a regular prism is given by the area of the base times the height.

Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.

Recall that the are of a triangle is given by 1/2 base times height.

Thus the area of of the pentagon base of the prism is given by
Area= \frac{5}{2} x\times2.8=7x

Therefore, the volume of the prism is given by
Volume=7x(2x+1)=14x^2+7x

Suppose the wholesale price of a certain brand of medium-sized eggs p (in dollars/carton) is related to the weekly supply x (in
Mrrafil [7]

Answer:

1300

Step-by-step explanation:

We are given

x = 35

\frac{dp}{dt}=-0.05  [rate of change of price with time]

We want to find \frac{dx}{dt}, which is the rate at which supply is changing.

First, we need to implicitly differentiate the equation given:

625p^2-x^2=100\\1250p\frac{dp}{dt}-2x\frac{dx}{dt}=0

Here, we have what we need except for p. We find p when x = 35:

625p^2 - x^2 =100\\625p^2 - (35)^2 =100\\625p^2=1325\\p=1.46

Now, find dx/dt:

1250(1.46)(-0.05)-2(35)\frac{dx}{dt}=0\\-91.25-70\frac{dx}{dt}=0\\\frac{dx}{dt}=-1.30

In thousands, 1.30 * 1000 = 1300 cartons per week decrease
