Answer:

Rounds to about 135% increase.

Step-by-step explanation:

Increase/original number x 100

324 / 239 × 100. This rounds to about a 135% increase.

I'm not sure about the answer, just saying. So you might want to double-check the formula for percent change. Thank You.

Answer:

 F = 0.792

Step-by-step explanation:

Given:

- The function C_o :

                               C_o (t) = 90*(e^-0.3t - e^-2.5t)

- The function C_i :

                               C_i (t) = 100*e^-0.3t

The function:

                               F = UAC_o / UAC_i = \frac{\int\limits^n_0 {C_o} \, dt }{\int\limits^n_0 {C_i} \, dt }

Find:

- The factor F.

Solution:

- Determine UAC_o from the function given:

                       UAC_o = integral ( 90*(e^-0.3t - e^-2.5t) ) dt

                       UAC_o = -300*e^(-0.3t) + 36*e^(-2.5t)

Evaluate integral from infinity to zero:

                      | UAC_o | = 300 - 36 = 264

- Determine UAC_i from the function given:

                       UAC_i = integral ( 100e-0.3t ) dt

                       UAC_i = -333.333*e^(-0.3t)

Evaluate integral from infinity to zero:

                      | UAC_i | =  0 + 333.333 = 333.3333

- Evaluate factor F:

                          F =  | UAC_o | / | UAC_i |

                          F = 264 / 333.3333

                         F = 0.792

Rewrite the equation by completing the square. f (x) = x^2 + 20x - 86
9966 [12]

Answer:

f(x) = (x+10)^2 - 86

Step-by-step explanation:

  1. f(x) = x^2 + 20x - 86
  2. f(x) = x^2 + 20x + 100 - 86 (because (20/2)^2 = 100)
  3. f(x) = (x+10)^2 - 86

Completing the square means you do (b/2)^2 where b is: a^2x + bx + c.

Option A: 40 trash bags for $6.29 Option B: 24 trash bags for $3.89
mr Goodwill [35]
Option B is a better option.

Step by step:

I divided 40/6.29 and got about 6.3.

I divided 24/3.89 and got about 6.1.

Which is less, 6.3 or 6.1?
If you said 6.1 you are correct, so option B has a less cost, making it a better option.
