The area of the mirror is 480 square inches

From the question, we have the following parameters that can be used in our computation:

A mirror that has the shape of a parallelogram (see attachment)

From the attachment, we have the following dimensions

Base length = 5 units

Height = 6 units

The area is the product of the dimensions

Since the side length of each square tile is 4 in, then we have

Area = 4 * 4 * 5 * 6

Evaluate

Area = 480

Hence, the area is 480 square inches

Out of the given statements, statement a. If 4 is a prime number, then 6 is a prime number is the false one. A prime number is a positive integer that has exactly two distinct natural number divisors: 1 and itself.

For example, the number 2 is a prime number because it can only be divided evenly by 1 and 2. 4 is not a prime number because it can be divided evenly by 1, 2, and 4. 6 can be divided evenly by 1, 2, 3, and 6, so it is not a prime number. Therefore, statement a is false because if 4 is a prime number, 6 is not a prime number.

When determining whether a number is a prime number, it is important to remember that 1 is not a prime number. This is because 1 only has one divisor - itself. Any other number that can be divided evenly by more than two distinct natural numbers is not a prime number.

The surface area of the open top box is 127 cm².

The area of a three dimensional object on it's outer surface is called the surface area of the object.

Given that,

Surface area of the open-top box = 2LH + 2WH + LW, where L is the length, W is the width and H is the height.

L = 3 cm

W = 5 cm

H = 7 cm

Surface area = (2 × 3 × 7) + (2 × 5 × 7) + (3 × 5)

                      = 42 + 70 + 15

If the mid point of AB is M (-4,-3). and the coordinates of A are (-1,-2), the coordinates of B is solved to be (-7, -4)

The midpoint of a line segment is the centroid of the segment. It is equally distant from both of the ends and hence cuts the section in half.

The formula to determine the center point of a straight line using the coordinates of its endpoints is known as the midpoint formula in coordinate geometry.

The formula is of the form

X= (x₂ + x₁)/2

Y = (y₂ + y₁)/2

From the formula the second end point is calculated

-4= (-1 + x₁)/2

-8 = -1 +  x₁

x₁ = -7

An equivalent expression to 7.5 + s using commutative property is; s + 7.5

The commutative property under addition is an algebra property that states that the change in the order of numbers in an addition operation does not change the sum.

This means that for any real numbers x, y, we have;

x + y = y + x

The commutative property under multiplication states that the change in the order of numbers in multiplication operation does not change the product.

This means that for any real numbers c, d we have;

c × d = d × c

The graph shows a solid line, which crosses the y-axis at 1 and the x-axis at 3, with shading above the line.

The slope-intercept form of a line is represented by y=mx+c where m=slope and c is the y-intercept of the line

Given here: The inequality y≥ -x/3 +1

Now, To graph an inequality, treat the <, ≤, >, or ≥ sign as an = sign, and graph the equation. If the inequality is < or >, graph the equation as a dotted line. If the inequality is ≤ or ≥, graph the equation as a solid line.

Therefore y=-x/3 +1 is a line in slope-intercept form with slope=-1/3 and y-intercept 1

Thus the line should intersect the y-axis  at y=1 and the x-axis at x=3

∴ The graph of this equation is plotted in attached file.

Hence, The graph shows a solid line, which crosses the y-axis at 1 and the x-axis at 3, with shading above the line.

The simplified form of (f o g)(x) = 8x²  + 8x + 4.

Differentiation is a process in calculus that is used to find the rate of change of a function at a specific point. It is the process of finding the derivative of a function.

To find (f o g)(x), we need to first find g(x) and then substitute that expression into f(x).

Given:

f(x) = 2x + 4

g(x) = 4x²  + 4x

So:

(f o g)(x) = f(g(x)) = f(4x²  + 4x) = 2(4x²  + 4x) + 4

Now we can substitute the expression for g(x) into f(x) and simplify:

= 2(4x²  + 4x) + 4 = 8x²  + 8x + 4

Hence, (f o g)(x) = 8x² + 8x + 4

When the ellipse has co-vertices at (4,0) and foci at (0,+-4), the equation is y2/32+x2/16=1.

The algebraic equation y=mx+b is known as a linear equation. M serves as the y-intercept, and B serves as the slope. The previous clause has two variables, y and x, and is sometimes referred to as a "linear equation with two variables". Bivariate linear equations are those with two independent variables. The following are a few examples of linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation takes the form y=mx+b, with m denoting the slope and b denoting the y-intercept, it is referred to as being linear. The term "linear" refers to an equation having the form y=mx+b, where m stands for the slope and b for the y-intercept.

There are 108 rabbits in the shelter.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

An animal shelter has 1008 cats, dogs and rabbits.

And, The ratio of the number of dogs to the number of cats in the animal shelter is 3 : 7. The ratio of the number rabbits to the number of dogs is  2 : 5.

Here, The ratio of the number of dogs to the number of cats in the animal shelter is 3:7. The ratio of the number rabbits to the number of dogs is 2:5.

So, We can formulate;

Number of dogs : Number of cats = 3 : 7

Number of rabbits : Number of dogs = 2 : 5

Hence, We get;

Number of rabbits : Number of dogs : Number of cats = 6 : 15 : 35

Since, An animal shelter has 1008 cats, dogs and rabbits.

Hence, We get;

⇒ 6x + 15x + 35x = 1008

⇒ 56x = 1008

⇒ x = 18

Thus, Number of rabbits = 6x

                                      = 6 × 18

The proof for the side AB congruent to side ED is given below.

Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.

Given that

C is the intersecting point of AD and EB.

Side AC is congruent to side EC.

Also ∠A = ∠E

By vertical angles theorem, a pair of intersecting lines form 2 pairs of vertically opposite angles which are equal.

Therefore, ∠ACB = ∠ECD

Also given that sides AC and EC are congruent.

By ASA congruence theorem, if two angles and an included side of a triangle is equal to the corresponding two angles and included side of another triangle, then the triangles are congruent.

So triangles ABC and CDE are congruent.

C is the common point for both the triangles.

So the side opposite to C are AB and ED.

So they are equal and thus congruent.

Hence the sides AB and ED are proved to be congruent.

On solving the exponential function 16000 = P(0.9455)^t, the original value of the car is obtained as $18,930.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The value of car in amount is A(t) = $16,000.

The rate of depreciation is x = 5.45% per year.

Rewriting the rate in exponential form - (1 - 0.0545) = 0.9455

The car is t = 3 years old.

Let P be the model that depicts the original cost of the car.

Then the exponential function will be -

16000 = P(0.9455)^t

Substituting the value of t in the equation -

16000 = P(0.9455)³

16000 = 0.8452P

P = 16000/0.8452486

P = 18,929.34 ≈ 18,930

Therefore, the original value of car was $18,930.
