HELP HELP HELP Find X for the log function!<br><br> Please include the steps
Keith_Richards [23]

Answer: yield x

Step-by-step explanation: Definition. The logarithm is denoted "logb x" (pronounced as "the logarithm of x to base b" or "the base-b logarithm of x" or (most commonly) "the log, base b, of x"). In the equation y = logb x, the value y is the answer to the question "To what power must b be raised, in order to yield x?".

Answer:

m=2

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

<u>Alg I</u>

  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (0, 7)

Point (4, 15)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{15-7}{4-0}
  2. Subtract:                       m=\frac{8}{4}
  3. Divide:                           m=2

A fence is to be built to enclose a rectangular area of 210 square feet. The fence along three sides is to be made of material t
Serhud [2]

Answer with explanation:

Let the length of rectangular fence = x meters

Let the width of the rectangular fence = y meters

Thus

Area=x\times y=210ft^{2}...........(i)

Now Let the total cost to construct the fence be 'C' can be obtained if we construct the shorter side with material with cost $12 per foot

\therefore C=5\times (2y+x)+12\times x\\\\C=10y+17x...............(ii)

Using value of x from the equation i into equation ii we get

C=10y+17\times \frac{210}{y}

hence to minimize the cost we differentiate both sides with respect to 'y' and equate the result to zero thus we get

C=10y+17\times \frac{210}{y}\\\\\frac{dC}{dy}=\frac{d}{dy}(10y+\frac{3570}{y})\\\\0=10-\frac{3570}{y^{2}}\\\\\therefore y=\sqrt{\frac{3570}{10}}=18.894feet

Thus x=\frac{210}{18.894}=11.11feet

Thus value of length = 11.114 feet and value of width = 18.894 feet.

Uniforms are sold into packages of 8. The store's 127 employees will be given 3 uniforms. How many packages will the store need
dsp73

Answer:

48 packages

Step-by-step explanation:

Hello There!

The first step is to find out how many uniforms they need to do so we multiply 127 and 3

3x127=381

Then we divide it by 8 ( because that's how many uniforms are sold in one package.)

381/8=47.625

you cannot have a 6th of a package so we just round to the nearest whole

so we can conclude that they will need 48 packages
