Answer:

<h2>282.857 in²</h2>

Step-by-step explanation:

The formula of a surface area of a cylinder:

S.A.=2\pi r^2+2\pi rH

r - radius

H - height

We have:

r = 5 in

H = 4 in

Substitute:

S.A.=2\pi(5^2)+2\pi(5)(4)=2\pi(25)+2\pi(20)\\\\=50\pi+40\pi=90\pi\ in^2

\pi\approx\dfrac{22}{7}

Substitute:

S.A.\approx90\cdot\dfrac{22}{7}=\dfrac{1980}{7}\approx282.857\ in^2

Write an equation for a rational function with: Vertical asymptotes at x = -1 and x = 3 x intercepts at x = -2 and x = -6 Horizo
dlinn [17]

Answer:

\frac{7(x+2)(x+6)}{(x+1)(x-3)}

Step-by-step explanation:

The vertical asymptotes need to be in the denominator. They become VA's when that small expression value equals zero.

x=-2 will become (x+2)

and x=-6 will become (x+6)

The x intercepts will be in the numerator.

x=-1 will go with (x+1) and x=3 will go with (x-3)

The horizontal A must be the quotient of the coefficient of the numerator and denominator, since both the top and bottom have the same power.

To make the quotient 7, we place a seven in the numerator so 7/1=7.

The claim is that the white blood cell counts of adult females are normally? distributed, with a standard deviation equal to 1.6
antiseptic1488 [7]
From the question, we know the population standard deviation, σ = 1.63, the sample standard deviation, s = 3.07, the sample mean, \bar{x}=7.43 and the sample size, n = 38.

The question illustrates a hypothesis chi-square test of variance.

The test statistics for a Chi-squared test of variance is given by
T=(n-1)\left( \frac{s}{\sigma} \right)^2 \\  \\ =(38-1)\left( \frac{3.07}{1.63} \right)^2 \\  \\ =37(1.883)^2=37(3.5473) \\  \\ =131.25

The quadratic parent function has been reflected down, stretched vertically by a factor of 1/3, shifted vertically by 9 units an
zmey [24]

Answer:

1a) f(x) = -1/3(x + 12)² + 9

1b) f(x) = -1/3x² - 8x - 39

General Formulas and Concepts:

<u>Algebra I</u>

Equality Properties

Expand by FOIL (First Outside Inside Last)

Standard Form: ax² + bx + c = 0

Transformations Graph: f(x) = a(bx - c)² + d

  • a = vertical shrink/stretch
  • b = horizontal shrink/stretch
  • c = horizontal movement left/right
  • d = vertical movement up/down

Step-by-step explanation:

<u>Step 1: Define</u>

Reflected down and vertically stretched by 1/3:   a = -1/3

Shifted vertically by 9 units:   d = 9

Shifted horizontally by -12 units:   c = -12

<u>Step 2: Write Vertex Form</u>

  1. Define:                    f(x) = a(bx - c)² + d
  2. Substitute:              f(x) = -1/3(x + 12)² + 9

<u>Step 3: Write Standard Form</u>

  1. Define:                              f(x) = -1/3(x + 12)² + 9
  2. Expand:                             f(x) = -1/3(x² + 24x + 144) + 9
  3. Distribute -1/3:                  f(x) = -1/3x² - 8x - 48 + 9
  4. Combine like terms:         f(x) = -1/3x² - 8x - 39

And we have our final answers!
