The length of the floor is obtained as 14 feet.

A rectangle is a type of parallelogram having equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

The kitchen floor can be considered as a rectangle.

The width is given as 7 feet.

Suppose the length of floor be x feet.

Since, the area of a rectangle is the product of length and width, the following equation can be written for the given case,

7x = 98

=> x = 98/7

       = 14

Hence, the length of the kitchen's floor is found to be 14 feet.

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]

Answer:

[tex]b=-\frac{a}{d}+c[/tex]

Step-by-step explanation:

[tex]d(c-b)=a\\\\\frac{d(c-b)}{d}=\frac{a}{d}\\\\c-b=\frac{a}{d}\\\\c-b-c=\frac{a}{d}-c\\\\-b=\frac{a}{d}-c\\\\\frac{-b}{-1}=\frac{\frac{a}{d} }{-1}-\frac{c}{-1}\\\\b=-\frac{a}{d}+c[/tex]

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

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)

(left to right)

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

11 is your answer :)

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
