We have the following functions:

f (x) = -3x ^ 4 - 14

g (x) = -x ^ 3 + 2f

Deriving both functions we have:

f '(x) = -12x ^ 3

g '(x) = -3x ^ 2

We equal zero and clear x:

f '(x) = -12x ^ 3 = 0 ----> x = 0

g '(x) = -3x ^ 2 = 0 -----> x = 0

Substituting x = 0 in the given equations:

f (0) = -3 (0) ^ 4 - 14 = -14

g (0) = - (0) ^ 3 + 2 = 2

Question

The surface area for a rectangular prism with a square base is SA=2s2+4sh. What is the surface area if s=2 and h=4?

Solution 1

We know that

[surface area for a rectangular prism with a square base ]=2*s²+4*s*h

2*s²----> Is the surface area of the bases

4*s*h---> is the lateral area

s=2 units

h=4 units

[surface area for a rectangular prism with a square base ]=2*2²+4*2*4

surface area=8+32----> 40 units²

**the answer is**

**40 units²**

[surface area for a rectangular prism with a square base ]=2*s²+4*s*h

2*s²----> Is the surface area of the bases

4*s*h---> is the lateral area

s=2 units

h=4 units

[surface area for a rectangular prism with a square base ]=2*2²+4*2*4

surface area=8+32----> 40 units²

Question

A camera manufacturer spends $2,100 each day for overhead expenses plus $9 per camera for labor and materials. The cameras sell for $14 each. a. How many cameras must the company sell in one day to equal its daily costs? b. If the manufacturer can increase production by 50 cameras per day, what would their daily profit be?

Solution 1

A. The company must sell 420 cameras, to make it equal to daily costs.

B. For making 50 more cameras each day, they'd make $250 dollars more per 50 cameras.

A. To find this, you can simply multiply 420 by $14. This will give you how much they make from selling that many cameras ($5,880). Next you need to multiply 420 by 9 (labor an material cost per camera), then add $2,100 (expenses). This will give you the same cost ($5,880), thus making them equal, and proving 420 is the answer.

B. To find this, you do the same steps as above, by replacing 420 with 470, (470*$14 = $6,580) and (470*9 + $2,100 = $6,330). Then you subtract $6,330 from $6,580. Thus getting $250.

I hope this helps!

Solution 2

A. The profit for each camera itself is $5 a camera. So, to make $2,100 dollars they would have to sell 420 cameras (2,100 / 5 = 420).

B. If they sold an extra 50 cameras a day, since they make $5 a camera, that would give them an extra profit of $250 a day.

B. If they sold an extra 50 cameras a day, since they make $5 a camera, that would give them an extra profit of $250 a day.

Question

The current size of an image on Samuel's computer is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 8 inches and the width is labeled as width equal to 10 inches. What are the dimensions of the image at fraction 1 over 2 times its current size

Solution 1

**Answer:**

**The length and the width of image is 4 inches and 5 inches respectively**

**Step-by-step explanation:**

**Given : **Length of rectangle is 8 inches

Width of rectangle is 10 inches

**To Find: **What are the dimensions of the image at fraction times its current size

**Solution:**

Length of rectangle is 8 inches

Since we are given that the dimensions of the image at fraction times its current size

So, Length of image =

**Thus the length of image is 4 inches.**

Width of rectangle is 10 inches

Since we are given that the dimensions of the image at fraction times its current size

So, width of image =

**Thus the width of image is 5 inches.**

**Hence the length and the width of image is 4 inches and 5 inches respectively.**

Solution 2

Length is equal to 4 and width is equal to 5.

You can just divide each by 2.

You can just divide each by 2.

Question

*Please help, will mark correct answer as brainliest* What is the formula for finding a break-even point?

Solution 1

The break-even point formula is calculated by dividing the total fixed costs of production by the price per unit less the variable costs to produce the product.

Break-even point in units =

Fixed costs/( Sales price per unit - Variable cost per unit )

Break-even point in Dollars = Break-even point in units * Sales price per unit

Break-even point in units =

Fixed costs/( Sales price per unit - Variable cost per unit )

Break-even point in Dollars = Break-even point in units * Sales price per unit

Solution 2

Answer:

break even point=(0.01)(# of points)(P)/monthly savings

Question

What is the surface area of the cylinder in terms of Pi? radius is 14in and height is 18 in A. 896 pi in^2 B. 504 pi in^2 C. 392 pi in^2 D. 350 pi in^2

Solution 1

**Answer:**

The answer is 896pi in.^2

**Step-by-step explanation:**

It may seem confusing as you get an answer in the thousands by plugging in the formula, but remember they are asking you to find the answer in "terms of pi". This means you have to divide the answer by 3.14.

2814/3.14 = 896pi in^2

Hope this helped!

Solution 2

The formula is A=2πrh+2πr2 thats the formula
