x(x+3)²(x-1)(x-3)²

I attached my guess, since I don't see any graphs.  

NOTE the x axis scale change on my submission.

Only option A graph matches the features of this polynomial. Therefore, option A is the correct answer.

A polynomial is an equation with many terms whose leading term is the highest exponent known as a degree. The degree or exponent tells how many roots exist. These roots are the x-intercepts.

This polynomial has roots -3, 0, 1, and 3. This means the graph must touch or cross through the x-axis at these x-values. What determines if it crosses the x-axis or if the simple touch it and bounces back? The even or odd multiplicity - how many times the root occurs.

In this polynomial:

Root -3 has an even multiplicity of 2 so it only touches and does not cross through.

Root 0 has an odd multiplicity of 1 so crosses through.

Root 1 has an odd multiplicity of 1 so crosses through.

Root 3 has an even multiplicity of 3 so it only touches and does not cross through.

Knowing this, only the first and second graphs are possible answers.

Lastly, what determines the facing of the graph (up or down) is the leading coefficient. If positive, the graph ends point up. If negative, the graph ends and points down. All even degree graphs will have this shape.

Only option A graph matches the features of this polynomial. Therefore, option A is the correct answer.

Answer:

25[tex]\pi[/tex] Or 78.5 units³

Step-by-step explanation:

1/3πr²h

1/3xπx25x3=25π or 78.5

Find the volume of the Cone.

We will substitute the given values in the formula,

⇒ Volume of Cone = [tex] \sf \frac{1}{3} \pi {r}^{2} h [/tex]

Substituting the values, We get,

⇒ Volume of Cone = [tex] \sf \frac{1}{3} \times 3.14\times 25 \times 3 [/tex]

On further calculating, We get,

∴ Volume of Cone = [tex] \sf 78.5 units³ [/tex]

Answer:

The least 5th score is 177

Step-by-step explanation:

Given

[tex]First\ 4: 103, 143, 101, 110.[/tex]

[tex]Average = 126.8[/tex]

Required

The least 5th score

Represent the 5th score with x.

The average is calculated as:

[tex]Average = \frac{\sum x}{n}[/tex]

So, we have:

[tex]126.8 = \frac{103 + 143 + 101 + 110 + x}{5}[/tex]

[tex]126.8 = \frac{457 + x}{5}[/tex]

Multiply both sides by 5

[tex]634= 457 + x[/tex]

Solve for x

[tex]x = 634- 457[/tex]

[tex]x = 177[/tex]

Answer:

a. 170 ft b. 126 ft

Step-by-step explanation:

a. How tall is the office building?

The two laser lights with the length of the taller office building, L form a triangle with sides 155.7 feet, 148.6 feet and L with angle 36° + 32° = 68° facing the taller office building.

We use the cosine rule to find the length of taller office building.

So, L² = 155.7² + 148.6² - 2(155.7)(148.6)cos68°

L² = 24242.49 + 22081.96 - 46,274.04(0.3746)

L² = 46324.45 - 17334.56

L² = 28989.89

L = √28989.89

L = 170.26 ft

L ≅ 170 ft

b. How far apart are the apartment complex and the office building?

Using one of the lights, the distance between the buildings, d, the laser light(being the hypotenuse side) and the building (being the opposite side)form a right angled triangle.

So, using the 155.7 feet light at 36 angle,

cos36 = d/155.7

d = 155.7cos36

d = 155.7(0.8090)

d = 125.96 ft

d ≅ 126 ft

Answer:

  12 inches

Step-by-step explanation:

The area is given by the formula ...

  A = 1/2bh

Fill in the given values and solve for the height.

  24 in² = 1/2(4 in)h

  h = (24 in²)/(2 in) = 12 in

The height of the triangle is 12 inches.

Answer:

12 inches

Step-by-step explanation:

Area = [tex]\frac{1}{2}bh[/tex]

24 = [tex]\frac{1}{2} * 4 * h[/tex]

Answer / Explaination:

An equation that represents this problem is b = 52h.

A linear model that represents this equation would look as such (see below)

To predict how many boxes would be produced after an 8 hour shift, you can look at the graph (see additional attatchement) or substitute 8 in for h in the equation.

b = 52(8)

b = 416

Answer:

I think it might be C but I dont know  . Hope its right !

Step-by-step explanation:

Answer:

Let R = cost per foot of redwood, and

let P = cost per foot of pine.

The 1st sentence gives us 60 ft * R + 90 ft * P = $303, and

the 2nd sentence gives us 90 ft * R + 60 ft * P = $357.

So this is two equations and two unknowns, so we should be able to solve these.

Solve the first equation for P: 60 ft * R + 90 ft * P = $303

Subtract 60 ft * R from both sides of the equation: 90 ft * P = $303 - 60 ft * R

Now divide both sides of the equation by 90 ft: P = ($303 - 60 ft * R) / 90 ft = $101 / 30 ft - 2/3 * R

Next, substitute P into the second equation: 90 ft * R + 60 ft * P = $357

so we then have 90 ft * R + 60 ft * [$101 / 30 ft - 2/3 * R] = $357.

Now solve for R (remember, parentheses, exponents, multiplication and division, addition and subtraction):

90 ft * R + [$202 - 40 ft * R] = 50 ft * R + $202 = $357, or 50 ft * R = $155; so R = $155 / 50 ft = $3.10 / ft.

Now we can substitute this value for R into the first equation and solve for P: 60 ft * R + 90 ft * P = $303

so we then have 60 ft * $3.10 / ft + 90 ft * P = $303, or $186 + 90 ft * P = $303.

Subtracting $186 from both sides of the equation, and then dividing by 90 ft, we have P = $1.30 / ft

So P = $1.30/ft, and R = $3.10/ft.

To check this answer, plug both into the second equation:

90 ft * R + 60 ft * P = $357

90 ft * $3.10/ft + 60 ft * $1.30/ft = $279 + $78 = $357

Answer:

24 gallons

Hope this helps! :)

Answer: 192

Step-by-step explanation:

So we know the hose sprays 24 gallons of water a minute. We also know that 8 pints equal a gallon. So to figure out how many pints are in one minute, we multiply 8 x 24, since we have 24 gallons a minute and 8 pints equal a gallon. This equals 192 pints a minute.

It would be at (7,5)

Solution :

This is the two tailed test.

The null hypothesis and the alternate hypothesis is as :

Null hypothesis is [tex]$H_0:\mu=110000$[/tex]

Alternate hypothesis is [tex]$H_0:\mu \neq110000$[/tex]

[tex]$\overline x = 112000, \ \mu = 110000, \sigma = 16100, n = 50, \alpha = 0.02$[/tex]

Therefore, the critical value of z is :

[tex]$z_{\alpha} = -2.33 \text{ and}\ 2.33$[/tex]

Now the test statics is :

[tex]$z=\frac{\frac{(\overline x - \mu)}{\sigma}}{\sqrt n}$[/tex]

[tex]$z=\frac{\frac{(112000-110000)}{16100}}{\sqrt {50}}$[/tex]

[tex]$z=0.87$[/tex]

The test statics is 0.878

We see that it is a right tailed test.

[tex]$P(z > 0.878)=1-P(z<0.878) = 1 - 0.81 = 0.19$[/tex]

[tex]$P- \text{value}= \ 2 \times 0.19$[/tex]

              = 0.3800

Thus , P-value > α

So we fail to reject the null hypothesis.

Answer:

65.5%

Step-by-step explanation:

Arrival rate, λ = average number of customers per hour = 38

Servive rate, μ = number of customers attended to per hour = 58

Utilization factor, ρ = λ / μ

ρ = 38 / 58

ρ = 0.6551724

Utilization rate (%) = 0.6551724 * 100% = 65.5%
