Answer:

Step-by-step explanation:

Let the original number = x

x+\frac{8.2}{100}*x=106\\\\x+0.082x=106\\\\1.082x=106\\\\x=\frac{106}{1.082}\\\\x=\frac{106*1000}{1.082*1000}\\\\x=\frac{106000}{1082}\\\\x=97.96\\\\

x=98.0

x=98

Vikki [24]

Answer:

The number of employees in 8 years  is  442

Step-by-step explanation:

Given:

Decreasing rate = 7%

Current number of employees = 790

To Find:

The number of employees after 8 years is this same rate continues =?

Solution:

Let the number of employees after 8 years be x

The current number of employees is:

790(1-0.07)^0=790---------------------------------(1)

since the decrase rate is 7% we use 0.07

So after 8 years , eq (1) can be rewritten as

790(1-0.07)^8= x

790(0.93)^8= x

790 \times 0.5595= x

x= 442.005

x= 442 (approx)

Use the definition f ′(x) = h0f(x + h) - f(x)h to find the derivative. f(x)=x+2
NNADVOKAT [17]

Answer:

f'(x) = 1

General Formulas and Concepts:

<u>Calculus</u>

  • Limit Properties: \lim_{n \to a} c = c
  • Definition of a Derivative: f'(x)= \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = x + 2

<u>Step 2: Find derivative</u>

  1. Substitute:                         f'(x)= \lim_{h \to 0} \frac{((x + h) + 2)-(x+2)}{h}
  2. Distribute:                          f'(x)= \lim_{h \to 0} \frac{x + h + 2-x-2}{h}
  3. Combine like terms:         f'(x)= \lim_{h \to 0} \frac{h}{h}
  4. Divide:                               f'(x)= \lim_{h \to 0} 1
  5. Evaluate:                           f'(x)= 1

azamat

Answer:

2

Step-by-step explanation:

<em>Add 1.5 to both sides:</em>

5/2x-1.5+1.5=3.5+1.5

5/2x=5

<em>Multiply both sides by 2/5</em>

(2/5)*(5/2x)=(2/5)*(5)
