Answer:

$716

Step-by-step explanation:

We we go through the chart provided here , the tax applied on your income is based on Income group and your status. Here Raoul is head of the household and his income falls in group $38400 to $38450. In this category the tax applied it $5144. He has already paid $4428. Hence remaining amount to be paid is their difference that it $716.

Hence he is supposed to make additional payment of $716 as tax towards his income earned

Answer:

$\displaystyle \: \frac{5}{4}$

Step-by-step explanation:

we are given a expression

we are said to solve it using L'Hôpital's Rule

recall, L'Hôpital's Rule:

$\displaystyle \lim _{x \to \: c}( \frac{f(x)}{g(x)} ) = \lim _{x \to \: c} \frac{f ^{'}(x) }{ {g}^{'}(x) }$

it is to say the ' means derivative

our given expression:

$\displaystyle\lim_{ x\to 2}\frac{x^2+x-6}{x^2-4}$

let's apply L'Hôpital's Rule

$\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)}$

some formulas of derivative

$\displaystyle \: \frac{d}{dx} {x}^{n} = {nx}^{n - 1}$

$\displaystyle \: \frac{d}{dx} {x}^{} = 1$

$\displaystyle \: \frac{d}{dx} {c}^{} = 0$

$\sf \displaystyle \: \frac{d}{dx} {f}^{} (x) + {g}^{}(x) = {f}^{'} (x) + {g}^{'}(x)$

use sum derivative formula to simplify:

$\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2)+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ \dfrac{d}{dx} (x^2) + \dfrac{d}{dx} (-4)}$

simplify using exponents using exponent derivative formula:

$\displaystyle\lim_{ x\to 2}\frac{ 2x+ \dfrac{d}{dx} (x) + \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}$

use variable derivative formula to simplify variable:

$\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ \dfrac{d}{dx}( -6)}{ 2x + \dfrac{d}{dx} (-4)}$

use constant derivative formula to simplify derivative:

$\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1+ 0}{ 2x + 0}$

simplify addition:

$\displaystyle\lim_{ x\to 2}\frac{ 2x+ 1}{ 2x }$

since we are approaching x to 2

we can substitute 2 for x

$\displaystyle\lim_{ x\to 2}\frac{ 2.2+ 1}{ 2.2 }$

simplify multiplication:

$\displaystyle\frac{ 4+ 1}{ 4}$

simplify addition:

$\displaystyle \: \frac{5}{4}$

hence,

$\displaystyle\lim_{ x\to 2}\frac{ \dfrac{d}{dx} (x^2+x-6)}{ \dfrac{d}{dx} (x^2-4)} = \frac{5}{4}$

When an object falls freely, the formula for the distance it falls is d= 4.9t^2 where d is

german

Answer:

a) 122.5 m ; b) 10 s

Step-by-step explanation:

Just use the given equation and plug in what you know.

d = 4.9t^2

d = 4.9(5^2)

d = 4.9 * 25

d = 122.5 m

d = 4.9t^2

490 = 4.9t^2

100 = t^2

t = 10 s
