A manufacturer wants to make a box with a volume of 24 cubic feet.a. Sketch two possible designs for the box.

b. If the box is to be made out of wood that costs $4 per square foot, which of your designs would be less expensive to produce? Explain.

Answers

First: You should know the formulas for volume and surface area of a rectangular prism.
V=whl
SA=2wl+2wh+2hl

Now, if our volume is 24 ft³, then the 3 dimensions of the box must multiply to make 24. We want to make two designs, so let's think of some possible dimensions.
Let's say...2 × 2 × 6 and 2 × 3 × 4.
You should be able to sketch boxes and label the sides. Just draw two rectangles and draw lines between all of the points. (see attached for reference)

Now all we have to do is find the surface area. Plug in our width, length, and height and solve.
First box
SA = 2wl + 2wh + 2hl
SA = 2×2×2 + 2×2×6 + 2×2×6
SA = 8 + 24 + 24
SA = 56
Second box
SA = 2wl + 2wh + 2hl
SA = 2×2×3 + 2×2×4 + 2×3×4
SA = 12 + 16 + 24
SA = 52

At $4 / ft²...
56 ft² = $224
52 ft² = $208

The second box is less expensive to produce because it has less surface area and therefore less wood needed to build the sides of the box.

Which three ordered pairs complete the table to give solutions of the equation y = x – 5?A.
(–3, –2), (0, –5), and (3, 2)

B.
(–3, –2), (0, –5), and (3, –2)

C.
(–3, –8), (0, –5), and (3, 2)

D.
(–3, –8), (0, –5), and (3, –2)

Answers

D. because  if you plug the X and Y coordinates into the equation. the equation will always be true
A
-2 = -3 - 5, -2 = -8 is wrong which means A is not the answer

B
-2 = -3 -5, -2 = -8 is wrong which means B is not the answer

C
-8 = -3 - 5, -8 = -8
-5 = 0 - 5, -5 = -5
2 = 3 - 5, 2 = -2 is wrong so C is not the answer

D
-8 = -3 -5, -8 = -8
-5 = 0 - 5, -5 = -5
-2 = 3 - 5, -2 = -2 
All are correct so D is the answer

Prove the identity cos(x-y)-cos(x+y)=2sinx siny

Answers

Answer:

see explanation

Step-by-step explanation:

Using the Addition/ Subtraction formulae for cosine

Consider the left side

cos(x - y) - cos(x + y)

= cosxcosy + sinxsiny - (cosxcosy - sinxsiny) ← distribute

= cosxcosy + sinxsiny - cosxcosy + sinxsiny ← collect like terms

= 2sinxsiny = right side ⇒ proven

-2(1+5a)= -6(a+3) what does a equal?

Answers

This is just a step by step thing if u need: −2(1+5a)=−6(a+3)Simplify both sides of the equation.−2(1+5a)=−6(a+3)Simplify−10a−2=−6a−18Add 6a to both sides.−10a−2+6a=−6a−18+6a−4a−2=−18Add 2 to both sides.−4a−2+2=−18+2−4a=−16Divide both sides by -4.−4a−4=−16−4Your Answer would be: A=4
