Answer:

D. undefined

General Formulas and Concepts:

Calculus

Derivatives

Derivative Notation

Derivative of a constant is 0

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Derivative Rule [Chain Rule]: $\displaystyle \frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Trig Derivative: $\displaystyle \frac{d}{dx}[sinu] = u'cosu$

Derivatives of Parametrics: $\displaystyle \frac{dy}{dx} = \frac{\frac{dy}{dt}}{\frac{dx}{dt}}$

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{dx}{dt} = 5$

$\displaystyle \frac{dy}{dt} = sin(t^2)$

Step 2: Differentiate

[x Derivative] Basic Power Rule: $\displaystyle \frac{d^2x}{dt^2} = 0$
[y Derivative] Trig Derivative [Chain Rule]: $\displaystyle \frac{d^2y}{dt^2} = cos(t^2) \cdot \frac{d}{dt}[t^2]$
[y Derivative] Basic Power Rule: $\displaystyle \frac{d^2y}{dt^2} = cos(t^2) \cdot 2t^{2 - 1}$
[y Derivative] Simplify: $\displaystyle \frac{d^2y}{dt^2} = 2tcos(t^2)$
[Derivative] Rewrite: $\displaystyle \frac{d^2y}{dx^2} = \frac{2tcos(t^2)}{0}$

Anything divided by 0 is undefined.

Clothes are us and ratcliffe's are having sales. At clothes are us, a pair of sneakers is on sale for 40% off the regular price

gregori [183]

50 x 0.4 = $20

$50 - $20 = $30

Ratcliff

$40 x 0.3 = $12

$40 -$12 = $28

Although, Clothes R Us discount is larger, Ratcliff has the better deal because the sneaker cost $28 vs clothes r us $30.

Write an equation that represents the line. (1,-1),(3,-5)

geniusboy [140]

Answer:

x+y=0

Step-by-step explanation:

slope m of given equations is

(-5+1)÷(3+1)

=-1

then the equations of this line is

y-(-1)=m(x-1)

or, y+1=-1(x-1)

or, y+1= -x+1

or, x+y=0

x+y=0 is required equation of line.
