Step-by-step explanation:
A rectangle rotated about an axis creates a cylinder
Answer:
29.05 ft
Step-by-step explanation:
Using the concept of pythagoras theorem, here we have the base and hypotenuse given hence we need to find the third dimension, assuming the wall is perfectly straight and forms a right angle with the bsse of the ladder. Here,
and making a the subject of the formula then
and substituting 30 ft for c and 0.25*30=7.5 ft for b then
Answer:
F(2)=2x+1=2*2+1=5
Step-by-step explanation:
Answer: 352 
Step-by-step explanation:
To find the Lateral area of a square pyramid , we will follow the three steps below:
1. Find the perimeter of the base
2. Multiply the perimeter by the slant height
3. Divide the result above by 2
That is :
The lateral surface area of a regular pyramid is lateral area = perimeter of base x slant height of pyramid) ÷ 2.
Applying the formula above:
1. The base is a square , therefore the perimeter of a square is 4L , That is
Perimeter = 4(8)
Perimeter = 32m
2. Perimeter x slant height , that is
32 x 22 = 704m
3. Dividing the result by 2 , we have :
704/2 = 352
Therefore , the Lateral area of the pyramid is 352 
Answer:
A. C(x) = 30.000 + 2500x
B. R(x) = 3125x
C. 48 items break even point
Step-by-step explanation:
A. The cost function C(x) is fixed cost plus variable cost.
In this case overhead works as fixed cost, we can write:
C(x) = 30.000 + 2500x
B. Revenue R(x) would be the price multiplied by quantity of items (x).
R(x) = 3125x
C. Break even point
To get the break even point we set R(x) = C(x) and find the value of x.
R(x) = C(x)
3125x = 30.000 + 2500x
3125x-2500x=30.000
625x=30.000
x=30.000/625
x=48
It means when you sell 48 items the costs will even revenue. So if you sell more than 48, then it's going to be profitable. If you sell less than 48, you will be losing money.
