The product of the functions is  2x³ + 8x² - 2x - 20. Then the correct option is C.

A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.

The functions are given below.

f(x) = x² + 2x - 5

g(x) = 2x + 4

Then the product of the functions will be given as

(f•g)(x) = f(x) × g(x)

(f•g)(x) = (x² + 2x - 5) × (2x + 4)

(f•g)(x) = 2x³ + 8x² - 2x - 20

The total time spent in minutes is 110 minutes

The given parameters are:

The total time is calculated as:

Total = Erica + Sean

So, we have:

Total = 1 hour, 15 minutes + 35 minutes

1 hour = 60 minutes

So, we have:

Total = 60 minutes + 15 minutes + 35 minutes

Evaluate the sum

Total = 110 minutes

Hence, the total time spent is 110 minutes

The area of the triangle based on the information given is 16.67 inches ²

It should be noted that the area of a triangle is given by the formula:

= 1/2 × base × height

In this second figure, the height will be:

= 5.9² - (3.4/2)²

= 5.9² - 1.7²

= 34.81 - 2.89

= 5.65

The area will be:

= 1/2 × base × height

= 1/2 × 5.65 × 5.9

= 16.67 inches ²

Step-by-step explanation:

the volume of a cylinder is as for any other regular 3D object :

ground area ×height

the ground area of a cylinder is a circle, so it is

pi×radius² × height

the radius is always half of the diameter (of the diameter is airways twice the radius).

radius = 6/2 = 3 ft.

the volume is then

pi × 3² × 9 = pi × 9 × 9 = pi × 81 ft³

so, the answer is 81pi ft³.

The garden with the largest area is garden b with an area of 6000 feet squares

The area of a rectangle is simply known as the number of unit squares that can fit into the rectangle.

The formula for calculating the area of a rectangle is written thus;

Area of a Rectangle = (Length × Breadth)

Using the formula:

Area of a Rectangle = (Length × Breadth)

For garden a;

Length = 25 feet

Breadth = 120 feet

Substitute the values into the formula

Area of garden a = 25 × 120 = 3000 feet squares

For garden b;

Length = 50 feet

Breadth = 120 feet

Substitute the values into the formula

Area of garden b = 50 × 120 = 6000 feet squares

Therefore, the garden with the largest area is garden b with an area of 6000 feet squares.

Answer:

3 family members get 126 text messages each

1 family member gets 127 text messages

Step-by-step explanation:

If you were finding the exact division of texts, 505 texts / 4 people, you would end up with 126.25 texts.

However, you can't get 0.25 of a text. If we take back each family member's 0.25 text, they will all be left with 126 texts (with an extra text leftover)

This extra text is considered the "remainder", meaning the amount left over when a number is divided [when it doesn't go into the larger number evenly]. The only importance/relevancy of a remainder is when a value cannot be split, such as a dog or a text.

So, we can give each family member 126 texts, and then we can give one family member an additional text, so that all texts are distributed.

This means that 3 family members get 126 texts, and 1 family member gets 127 texts

The area of the new patio if the original patio measures 13 feet by 13 feet is 133 ft².

Ezra has a square brick patio. he wants to reduce the width by 6 feet and

increase the length by 6 feet.

The area of the square is the measure of the space occupied by it. It is equal to the product of the measure of its two sides.

We need to write the expression for the new patio and the area of the new patio if the original patio measures 13 feet by 13 feet.

let x be the measure of the side of a square.

The length increased by 6 ft, so the new length=x+6.

The width decreased by 6 ft, so the new width=x-6.

The area is the product of length and width, so the new area is

l×w = (x+6)×(x-6)

Since the original side is 13 ft, the new length is 13+6 = 19 ft, and the new width is 13-6=7 ft.

So, the area is (19 ft)×(7 ft) = 133 ft²

Hence, the area of the new patio if the original patio measures 13 feet by 13 feet is 133 ft².

Considering the given quadratic function, the correct statement is given by:

The airplane reaches its maximum height of 95 feet in 10 seconds.

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient. If a > 0, the vertex is a minimum point, and if a < 0 it is a maximum point.

In this problem, the function is:

h(t) = -(t - 10)² + 95.

Hence the vertex is (10, 95), and since a < 0, the correct statement is given by:

C.  y = 20

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}3y = 18x + 6\\y = 2x + 14\end{cases}[/tex]

Multiply the second equation by 3:

[tex]\implies (3)y=(3)2x+(3)14[/tex]

[tex]\implies 3y=6x+42[/tex]

Subtract this from the first equation to eliminate 3y:

[tex]\begin{array}{r l}3y & = 18x+6\\-\quad3y&=6x+42\\\cline{1-2}0&=12x-36\end{array}[/tex]

Solve the resulting equation for x:

[tex]\implies 12x-36=0[/tex]

[tex]\implies 12x=36[/tex]

[tex]\implies x=3[/tex]

Substitute the found value of x into the original second equation and solve for y:
