60% of 90

= (60/100) x 90

= 6/10 x 90 = 54.

Half of 100 =  (1/2) x 100 = 50.

Therefore 60% of 90 is greater.

(90/100) x 60 = 54
60% of 90 = 54. 
(100/100) x 50 = 50
50% of 100 = 50

<em>60% of 90 is bigger than 50% (half) of 100. </em>

Find the area of a circle with a diameter of 19 inches
8_murik_8 [283]

to find the area you have to do:

Area = π( D/2)^2 and in this case D = 19 so..

    π(19/2)^2

            =90.25π

            =283.52873698648

Answer: 283.53

At the indicated point find (a) the slope of the curve and (b) an equation of the tangent line.
Marianna [84]

Answer:

Slope of the Curve: f'(x)=\frac{-6}{x^2}

Equation of Tangent Line: y + 3 = -3/2(x + 2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

<u>Calculus</u>

The definition of a derivative is the slope of the tangent line.

Basic Power Rule:

  • f(x) = cxⁿ
  • f’(x) = c·nxⁿ⁻¹

Quotient Rule: \frac{d}{dx} [\frac{f(x)}{g(x)} ]=\frac{g(x)f'(x)-g'(x)f(x)}{g^2(x)}

Step-by-step explanation:

<u>Step 1: Define</u>

<u />f(x)=\frac{6}{x}<u />

<u />

<u>Step 2: Take Derivative</u>

  1. Quotient Rule:                    f'(x)=\frac{0(x)-6(1)}{x^2}
  2. Multiply:                              f'(x)=\frac{0-6}{x^2}
  3. Subtract:                             f'(x)=\frac{-6}{x^2}

<u>Step 3: Find Instantaneous Derivative</u>

  1. Substitute in <em>x</em>:                     f'(x)=\frac{-6}{(-2)^2}
  2. Exponents:                           f'(x)=\frac{-6}{4}
  3. Simplify:                               f'(x)=\frac{-3}{2}

This value shows the slope of the tangent line at the exact value of x = 2.

  1. Substitute:                    y + 3 = -3/2(x + 2)
