Answer:

E. Graph E

Step-by-step explanation:

1: Find critical points of inequality.

  • One critical point is 0; we have to solve for the other.
  • \sqrt{x} = 2

Step 1: Square both sides.

  • x = 2^2
  • x = 4

Step 2: Check if solution is correct.

  • \sqrt{4} = 2
  • 2 = 2

2. Check the intervals between critical points.

  • x ≤ 0: doesn't work  
  • 0 ≤ x ≤ 4: does work
  • x ≥ 4: doesn't work

3. Now that we know the interval is 0 ≤ x ≤ 4, we look for the graph that matches this inequality.

  • Note: This inequality means that the values include 0, 4, and the values in between them
  • Given the information above, the correct answer is E because it includes 0, 4, and the numbers between.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

A, d and e

Step-by-step explanation:

So take the numbers a multiply them by nine. if they are more than 117, then they are correct, but with D 9x13 is equal to 117 so it is part of the solution set.

Aubrey is making cone-shaped hats for a birthday party. She mistakenly thinks that she will need about 104 square inches of pape
Mashutka [201]

Answer:

Option C. is the correct option.

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Aubrey is making cone-shaped hats for a birthday party. She mistakenly thinks that she will need about 104 square inches of paper for each hat.

Cone with diameter six inches and slant height eight inches.

What is the correct amount of paper Aubrey will need per hat? Explain Aubrey’s mistake. Use 3.14 for π and round to the nearest inch.

A.  About 70 in2; Aubrey found the surface area of the cone, but did not include the base.

B.  About 70 in2; Aubrey used the diameter instead of the radius to find the surface area of a cone.

C.  About 75 in2; Aubrey found the surface area of the cone and included the base.

D.  About 75 in2; Aubrey found the volume of the cone instead of the surface area.

Lateral surface area of a cone = Paper required to for each hat

Lateral surface area = πrl

Here r = radius of the cone

l = lateral height of the cone

Lateral surface area = π(3)(8)

                                 = 75.36 square inches

                                 ≈ 75 square inches

Therefore, total paper required for each cap is about 75 square inches.

Total surface area of the cone (Lateral area + Area of the base)

= πr(r + l)

= 3.14(3)(3 + 8)

= 103.62

≈ 104 square inches.

Aubrey did a mistake by finding the total surface area (including base area) of the cone instead of lateral surface area.

Therefore, option C. is the correct option.
