**Answer: quadratic polynomial **

**Step-by-step explanation:**

A quadratic polynomial is a polynomial of degree 2. A univariate quadratic polynomial has the form f(x)=a_2x^2+a_1x+a0. An equation involving a quadratic polynomial is called a quadratic equation. A closed-form solution known as the quadratic formula exists for the solutions of an arbitrary quadratic equation.

What is the factored form of the polynomial?

f2 + 9x +20

(x - 4)(x - 5)

(x - 2)(x - 10)

(x + 4)(x + 5)

(x + 2)(x + 10)

Answer:

(x + 4)(x + 5)

Step-by-step explanation:

If you FOIL these factors, you get the give quadratic polynomial. x×x = x^2 4×5 = 20. 4x + 5x = 9x

A 10-foot ladder is to be placed Against the side of the building. The base of the latter must be placed in an angle of 72° With the level ground for a secure footing. Find, to the nearest inch, how far the base of the latter should be from the side of the building and how far up the side of the building the latter will reach.

**Answer:**

**Distance of foot of ladder from building: ****37.2 inches
**

**Distance of top of ladder from building's base: ****114 inches
**

**Step-by-step explanation:**

Please refer to the figure attached in the answer area.

A **right angled triangle** [tex]\triangle ABC[/tex] is formed by the ladder with the building where **hypotenuse is the length **of ladder.

**Hypotenuse**, ** AC **=

Also, we are given that angle made by the base of ladder with the ground is [tex]72^\circ[/tex].

We have **to find ***AB* and *BC*.

[tex]\angle BAC = 72^\circ[/tex]

Using **trigonometric functions**:

[tex]cos \theta= \dfrac{Base}{Hypotenuse}\\cos 72^\circ= \dfrac{AB}{AC}\\\Rightarrow 0.309 = \dfrac{AB}{AC}\\\Rightarrow AB = 10 \times 0.309\\$\approx$ 3.1 foot\\$\approx$ 37.2 inches[/tex]

[tex]sin \theta = \dfrac{Perpendicular}{Hypotenuse}\\\Rightarrow sin72^\circ = \dfrac{BC}{AC}\\\Rightarrow 0.95 = \dfrac{BC}{AC}\\\Rightarrow AB = 10 \times 0.95\\$\approx$ 9.5 foot\\$\approx$ 114 inches[/tex]

**Distance of foot of ladder from building: ****37.2 inches
**

**Distance of top of ladder from building's base: ****114 inches

Determine the values of the variables in isosceles trapezoid CHLE below.

Enter numbers only, do not enter units.

Answer:

The values of variables x and m are 11 and 17

Step-by-step explanation:

The question has missing details as the diagram of the trapezoid isn't attached.

(See attachment).

Given that trapezoid CHLE is isosceles then the angles at the base area equal (4x)

And

The angles at the top are also equal

8m = 11x + 15

At this point, the four angles in the trapezoid are 8m, 11x + 15, 4x and 4x..

The sum of interior= 360

So,

11x + 15 + 8m + 4x + 4x = 360

Collect like terms

11x + 4x + 4x + 8m = 360 - 15

19x + 8m = 345

Substitute 11x + 15 for 8m

19x + 11x + 15 = 345

30x + 15 = 345

30x = 345 - 15

30x = 330

Divide through by 30

30x/30 = 330/30

x = 11

Recall that 8m = 11x + 15;

8m = 11(11) + 15

8m = 121 + 15

8m = 136

Divide through by 8

8m/8 = 136/8

m = 17

Hence, the values of variables x and m are 11 and 17

Health Club Fees You are choosing between two health clubs Club A offers membership for a fee of $7 plus a monthly fee of $23. Club B offers membership for a

tee of $35 plus a monthly fee of $16. After how many months will the total cost of each health club be the same?

in month(s) the total cost of each health club will be the same

**Answer: The solution is (4,99) which means for in 4 months the total cost of each health club will be the same. **

**Step-by-step explanation:**

Club A can be represented by the equation y = 23x + 7 where x is the number of months and y is the cost.

Club B can be represented by the equation y = 16x + 35 where x is the number of months and y is the cost.

23x + 7 = 16x + 35 set the equation equal each other to solve for x

-7 -7

23x = 16x + 28

-16x -16x

7x= 28

x= 4 now we know the value of x is 4 so we will put it into the equation and solve for y

y= 16(4) + 35

y= 99

A sector with a radius of 8 cm has an area of 56pi cm2. What is the central angle measure of the sector in radians?

**Answer:**

[tex]\frac{7\pi}{4}[/tex].

**Step-by-step explanation:**

Given information:

Radius of circle = 8 cm

Area of sector = [tex]56\pi\text{ cm}^2[/tex]

Formula for area of sector is

[tex]A=\dfrac{1}{2}\theta r^2[/tex]

where, r is radius and [tex]\theta[/tex] is central angle in radian.

Substitute [tex]A=56\pi[/tex] and r=8 in the above formula.

[tex]56\pi=\dfrac{1}{2}\theta (8)^2[/tex]

[tex]56\pi=\dfrac{64}{2}\theta[/tex]

[tex]56\pi=32\theta[/tex]

[tex]\dfrac{56\pi}{32}=\theta[/tex]

[tex]\dfrac{7\pi}{4}=\theta[/tex]

**Therefore, the measure of the sector in radians is [tex]\frac{7\pi}{4}[/tex].**

An aquarium in the shape of a rectangular prism has a bottom, no top, two square sides, and two sides

the same height as the square sides but twice their length. The total area of the five sides 15 2,592 in?.

Find the volume of the aquarium. Complete the explanation of your reasoning.

Let x represent the length and height of the square sides. Then the longer sides and the bottom measure

2x by x. The total area of the five sides, in terms of x, is A =____

So, the total area of the five sides,

A, is 2,592 in2. Solving for x we get x =____

The tank's volume is ____

in squared?

**Answer:**

volume = 11,664 units cubed

**Step-by-step explanation:**

2[tex]x^{2}[/tex] times 3 = bottom and sides

[tex]x^{2}[/tex] times 2 = ends

A = 6[tex]x^{2}[/tex] + 2[tex]x^{2}[/tex] = 8[tex]x^{2}[/tex]

2592 = A

2592/8 = 8[tex]x^{2}[/tex]/8

324 = [tex]x^{2}[/tex]

take square root of both sides

18 = x

so volume = length times width times height

2(18) times 18 times 18 = 11664

11664 units cubed

The height of an object launched upward from ground level is given by the function s(t) = -4.9t2 + 78.4t, where s(t) is the height in meters and t is the time in seconds. Arrange the time intervals in ascending order of the object's magnitude of average velocity over the interval.

**Answer:**

the distance of the object before it hits the ground after launch is t = 1.592 seconds

**Step-by-step explanation:**

The height of an object launched upward from ground level is given by the function s(t) = -4.9t² +7.8t

when the object reach the ground then s(t) = 0

So; -4.9t² +7.8t = 0

-4.9t² +7.8t + 0 = 0

By using the quadratic equation

[tex]\mathbf{\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}}[/tex]

where; a = -4.9 ; b = 7.8 and c = 0

[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(7.8)^2-4(-4.9)(0)} }{2(-4.9)}}[/tex]

[tex]\mathbf{=\dfrac{-(7.8) \pm \sqrt{(60.84} }{-9.8}}[/tex]

[tex]\mathbf{=\dfrac{-(7.8) + \sqrt{(60.84} }{-9.8} \ \ \ \ OR \ \ \ \ \mathbf{\dfrac{-(7.8) - \sqrt{(60.84} }{-9.8}}}[/tex]

[tex]\mathbf{=0 \ \ \ OR \ \ \ 1.592 }}[/tex]

Hence; the distance of the object before it hits the ground after launch is t = 1.592 seconds

The volume of a cylinder is 40 ft which expression represents the volume of O.C. one with the same base and height as the cylinder

**The volume of a cylinder is 40 ft which expression represents the volume of a Cone with the same base and height as the cylinder?**

**3(40) ft³**

**3(1/40) ft³**

**1/3(40)ft³**

**1/3(40²) ft³**

**Answer:**

The expression that represents the volume of a cone is ** **[tex]\frac{1}{3}[/tex]** (40)** ft³

**Step-by-step explanation:**

To find the expression that represents the volume of a cone with the same height and base as the cylinder, we will follow the steps below:

First write down the formula for calculating volume of a cone and volume of a cylinder

volume of a cone = [tex]\frac{1}{3}[/tex] πr²h

volume of a cylinder = πr²h

If the base are the same, this implies they have the same radius, and from the question, it states that they have the same height, hence;

volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

from the question, the volume of the cylinder is 40 ft³

volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

= [tex]\frac{1}{3}[/tex] (40) ft³

volume of a cone = [tex]\frac{1}{3}[/tex] (40) ft³

Therefore the expression that represents the volume of a cone is ** **[tex]\frac{1}{3}[/tex]** (40)** ft³
