The missing side length of perimeter of the figure is 15 feet is 5.

To get the length of the missing side, subtract the perimeter from the total of the known sides. Advice: Consider it. The whole and one component are both known. You deduct the known portion from the total to determine the missing component.

Since there are two of each side length, it is easy to do this by simply adding the length and breadth and multiplying the result by two. The perimeter formula is defined as

perimeter=(length + width)2.

On December 31 of each year, the quick ratio is 1.6. According to the above computation, the quick ratio is improving.

A good fast ratio is often anything greater than 1 or 1:1. If the ratio is 1:1, the company's liquid assets and current liabilities are equal in amount. A greater ratio means the business could more than cover its current liabilities.

For the present year

Current liabilities minus Quick Assets is the Quick Ratio.

= ($1,000 + $1,200 + $800) ÷ $1,875

= $3,000 ÷ $1,875

= 1.6

Current liabilities minus Quick Assets is the Quick Ratio.

The area of the napkin will be 162.5 inches².

The area of a square is -

{A} = Side x Side

Given is that a square piece of cloth with an area of 324 inches² is folded in half twice to form the napkin.

The area of the cloth is -

{A} = 324

Let the side of the square cloth be {a}. So, we can write -

a² = 324

a = √324

{a} = 18                                              ... Eq { 1 }

The diagonal of the square will be the base length of the napkin (in the form of triangle). So, we can write -

d² = a² + a²

d² = 2a²

d² = 648

d = √648

{d} = 25.5 inches                                       ... Eq { 2 }

The height would be -

h = d/2

h = 25.5/2

{h} = 12.75

The area of the napkin would be -

1/2 x d x h

1/2 x 25.5 x 12.75

162.5 inches²

Therefore, the area of the napkin will be 162.5 inches².

The transformation from the function f(x)=1/x to g(x)=1/5x can be achieved by multiplying the input value x by 5.

f(x)=1/x becomes g(x)=1/(5x) after the transformation

A mathematical transformation is a function that maps one set of values (input) to another set of values (output) based on a set of rules or operations. Transformations can be used to manipulate geometric figures, to change coordinate systems, to map one image to another, and more. Common examples of mathematical transformations include translation, rotation, scaling, and reflection.

The solution of the system of equations is (8, 11).

We know that one of the equations of the system is:

y = x + 3

And the other line passes through the points (3, 1) and (4, 3), then the slope of that line is:

a = (3 - 1)/(4 - 3) = 2

So the line is something like:

y = 2*x + b

To find the value of b, the y-intercept, we can replace the values of one of the points.

I will use (3, 1)

1 = 2*3 + b

1 = 6 + b

1 - 6 = b

-5 = b

So the other line is y = 2x - 5

Then the system of equations is:

y = x + 3

y = 2x - 5

Now we can solve the system:

x + 3 =2x - 5

3 + 5 = 2x -x

8  =x

The x-value of the solution is 8, then the only option that can be correct is.

The function is continuous only if m = 7.

If the function is continue, then the value of the function needs to be the same one in both pieces of the function when we evaluate in x = -2

That means that:

f(-2) = f(-2)  (trivially)

Replacing the two pieces of the function we will get:

m*(-2) - 6 = (-2)^2 + 10*(-2) - 4

now we can solve that equation for m.

-2m - 6 = 4 -20 - 4

-2m = -20 + 6 = -14

m = -14/-2 = 7

m = 7

The true statement is "viet's car can uses 13 gallons of gas for every miles it travels.

The correct answer choice is option B.

Julio's car:

m = k × g

Where,

m = miles traveled

g = gallons of gas used

m = k × g

300 = k × 12

300 = 12k

divide both sides by 12

k = 300/12

k = 12

The value of function for f'(2) is 0.22.

The process of finding derivatives of a function is called differentiation in calculus. A derivative is the rate of change of a function with respect to another quantity.

f'(2)= [tex]\lim_{h \to \ 0}[/tex]((f(2+h)-f(2))/h)

Find the derivative using the chain and power rules.

[tex]f(x)=(x+3)^{\frac{1}{2} }[/tex]

f'(x) = [tex]\frac{1}{2(x+3)^{\frac{1}{2} }}[/tex]

f'(2)=  [tex]\frac{1}{2(2+3)^{\frac{1}{2} }}[/tex]
