The bike you have been saving for is discounted 25%. You have $600 saved to purchase it. The original, non-discounted price of the bike is $675. There is a 5.77% sales tax added to the price of the bike. After you purchase the bike with the discount and sales tax, how much money will you have left over? Round your answer to the nearest dollar.

Answers

Answer:

65

Step-by-step explanation:

find discounted price

675*0.25=168.75

675-168.75=506.25

then add tax

506.25*1.0577=535.46(rounded)

Answer:

x = 16

y = 70.4

Step-by-step explanation:

Two triangles are similar, so we can use the similarity ratio to so find the variables

(2.8)/(22.4) = (8.8)/y cross multiply expressions

197.12 = (2.8)*y divide both sides by 2.8

70.4 = y

use same operation to find x

(2.8)/(22.4) = x/128 cross multiply expressions

358.4 = (22.4)*x divide both sides by 22.4

16 = x

If f(x)= [tex]\sqrt{x^2-4}[/tex] and g(x)=3x-2, then the derivative of f(g(x)) at x=3 is

Answers

Answer:

[tex]\displaystyle \frac{d}{dx}\Big|_{x=3} & = \frac{9(3)-6}{\sqrt{(3(3)-2)^2-4}} = \frac{7\sqrt{5}}{5}[/tex]

Step-by-step explanation:

We are given the two functions:

[tex]\displaystyle f(x) = \sqrt{x^2 -4} \text{ and } g(x) = 3x-2[/tex]

And we want to find:

[tex]\displaystyle \frac{d}{dx}\left[f(g(x))\right] \text{ at } x = 3[/tex]

Recall that from the chain rule:

[tex]\displaystyle \frac{d}{dx}\left[ f(g(x))\right] = f'(g(x)) \cdot g'(x)[/tex]

Hence, find both f'(x) and g'(x).

The derivative of f(x) can be determined using the chain rule:

[tex]\displaystyle \begin{aligned} f'(x) &= \frac{d}{dx}\left[ \sqrt{x^2-4}\right]\\ \\ & = \frac{1}{2\sqrt{(x^2-4)}}\cdot \frac{d}{dx}\left[x^2-4\right] \\ \\ & = \frac{x}{\sqrt{x^2-4}} \end{aligned}[/tex]

Because g(x) is simply a linear function, its derivative will be the slope of the linear function at any point. That is:

[tex]\displaystyle g'(x) = 3[/tex]

Hence:

[tex]\displaystyle \begin{aligned} \frac{d}{dx}\left[f(g(x))\right] & = \frac{(g(x))}{\sqrt{(g(x))^2-4}} \cdot (3) \\ \\ & = \frac{9x-6}{\sqrt{(3x-2)^2-4}} \end{aligned}[/tex]

Then at the point x = 3, the derivative is:

[tex]\displaystyle \frac{d}{dx}\Big|_{x=3} & = \frac{9(3)-6}{\sqrt{(3(3)-2)^2-4}} = \frac{7\sqrt{5}}{5}[/tex]

option B is correct, the money Luna left with is $20.00-(3×2.25+3.85)

What is Expression?

An expression is combination of variables, numbers and operators.

Given that Luna goes to the convenience store with $20.00.

Luna buys 3 frozen drinks for $2.25 each and a snack for $3.85.

The cost for 3 frozen drinks will be 3×$2.25

The cost of snacks is $3.85.

To find the money left we have to subtract the amount spend for drinks and snack.

$20.00-(3×2.25+3.85)

Hence, option B is correct, the money Luna left with is $20.00-(3×2.25+3.85)

4²-(3.1+6.4)+4.5

According to PEMDAS, we will do what is inside the parenthesis.

3.1+6.4 = 9.5

4²-9.5+4.5

Then we do figure out the exponent.

4² =  (4)(4) = 16

16-9.5+4.5

Then we do subtraction then addition because PEMDAS also tells us we should do adding and subtracting from left to right. In this expression, subtracting is on the left side so we should do that first.

16-9.5 = 6.5

6.5 + 4.5 = 11
