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.

Solve 8x 2 - 2x - 1 = 0 {-1/4, 1/2} {-1/2, 1/4} {1/2}

Kamila [148]

8x^2 - 2x - 1 = 0
(2x - 1)(4x + 1) = 0
2x - 1 = 0; x = 1/2
4x + 1 = 0;x = -1/4

answer
{-1/4, 1/2}

What is the distance from the spotlight to be base of the tree, rounded to the nearest meter?

Luda [366]

Answer:
14

Explanation:
The given triangle is a right-angled triangle. This means that special trig functions can be applied.
These functions are as follows:
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent

Now, we have:
θ = 40°
opposite = 12 m
adjacent is the distance we want to find

Substitute with the givens in the tan formula to get the distance as follows:
tan (40) = 12 / distance
distance = 12 / tan (40)
distance = 14.3 which is approximately 14 m

Hope this helps :)

Please Help I need ot now!!!!!! Ms. Moore is purchasing a house and needs to finance a $150,000 mortgage from the bank with an

alina1380 [7]

$251,618

Step-by-step explanation:

Amount = $ 150,000

APR = 3.8 % = 3.8 / 100 = 0.0038

Rate per month = 0.003166

Monthly payment = 30 years = 360 months

Interest = P* r/n (1 + r/n) ∧ nt ÷ (1 + r/n) ∧ nt - 1

The total amount Ms Moore will pay back to the bank =

= $251,618
