Perimeter = 2L + 2W →  240 = 2L + 2W  →  120 = L + W  → 120-L = W
Area = L x W  → Area = L(120-L)  →  Area = 120L - L²
Find the derivative:
dA/dL = 120 -2L → 0 = 120 - 2L → L = 60

Area = 120L - L² = 120(60) - (60)²  = 7200 - 3600 = 3600

The maximum area is 3600 yds²

Mia is calculating the volume of the cylinder below using the following work. A cylinder with height of 47 meters and diameter o
inn [45]

Mia’s first error was " she forgot to multiply π by (17.5)²(47) "

Step-by-step explanation:

The formula of the volume of a cylinder is V = π r² h, where

  • r is the radius of the base of the cylinder
  • h is the height of the cylinder

∵ The diameter of the base of the cylinder is 35 meters

∵ The radius = \frac{1}{2} × diameter

∴ The radius = \frac{1}{2} × 35 = 17.5 meters

∴ r = 17.5

∵ The height of the cylinder = 47 meters

∴ h = 47

- Substitute r and h in the formula of the volume

∴ V = π (17.5)²(47)

∵ Mai's first step is V = (17.5)²(47)

- She forgot to put π

∴ Her first error is she forgot to multiply π by (17.5)²(47)

Mia’s first error was " she forgot to multiply π by (17.5)²(47) "

Answer:

\sf \bold{ 1 * (-3)^{n-1}}

Explanation:

first term, a₁ = 1

difference between the terms: -3

  • used geometric formula : \bold{\sf  a_1 * (r)^{n-1}}

<u>where "a₁ is first term" and "r refers to common difference"</u>

  • formula for this nth term: \sf \bold{ 1 * (-3)^{n-1}}

HELP!! 4 questions !!! easy points!! 25 points!! please answer quick!
Afina-wow [57]

Step-by-step explanation:

(i) From the graph value of x varies -3 to 3 i.e.

-3\leq x\leq 3

and domain in the input values which function can take

So, option (d) is correct.

(ii) option (d) is correct as it represent the function y=x. While all the other function does not satisfy the given conditions.

(iii) (-14,-15), (-9,-10) are the parts of solution pair.

(iv) Option (c) and (d) represents the function as each element of the first set has a unique image in the second set.
