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:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate
y₁ - y coordinate
m - slope

Calculus

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:

Step 1: Define

$f(x)=\frac{6}{x}$

Step 2: Take Derivative

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

Step 3: Find Instantaneous Derivative

Substitute in x: $f'(x)=\frac{-6}{(-2)^2}$
Exponents: $f'(x)=\frac{-6}{4}$
Simplify: $f'(x)=\frac{-3}{2}$

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

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

Mashcka [7]

Jenna has a bag that contains the following
=> 7 red marbles
=> 25 blue marbles.
She selects a marble at random, and then, without replacing the first one, selects another marble at random.
=> 7 + 25 = 32 marbles are there in all.
For blue marble
=> 1/32 is the probability
For red
=> 1/31 is the probability
or
3%

Answers please with work, thanks!

When I divided 4/7, I got .5714285714 then I divided 13/20, and I got .65 so I would say 4/7 I believe.

When I divided 1/4, I got .25 then I divided 1/6, and I got .1666666667 so I would say 1/4 I believe.

When I divided 5/6, I got .8333333333 then I divided 2/3, and I got .6666666667 so I would say 5/6 I believe.

I definitely hope this helps you, I tried my best! XO
