[tex]f(x) = x^3 + x^2 - 8x - 8[/tex]

Lets find the number of zeros by factoring

[tex]0 = x^3 + x^2 - 8x - 8[/tex]

Group first two terms and last two terms

[tex]0 = (x^3 + x^2) (- 8x - 8)[/tex]

Factor out GCF from each group

[tex]0 = x^2(x + 1)-8(x + 1)[/tex]

[tex]0 = (x^2-8)(x + 1)[/tex]

Now we set each factor =0 and solve for x

0 = (x^2-8)             and   (x + 1)=0

[tex]x^2 = 8[/tex]            and x = -1

[tex]x= 2+-\sqrt{2}[/tex]     and x= -1

So we have three real zeros

Answer:

The last graph.

Step-by-step explanation:

In the first graph, the darker triangle has one side that is 1/3 of the corresponding side of the other triangle, and one side that is 2/5 of the corresponding side of the other triangle.  This is not proportional for all sides, so this is not a dilation.

In the second graph, the darker triangle has one side that is 1/2 of the corresponding side of the other triangle, and one side that is 3/5 of the corresponding side of the other triangle.  This is not proportional for all sides, so this is not a dilation.

In the third graph, the darker triangle has one side that is 1/3 of the corresponding side of the other triangle, and one side that is 1/2 of the corresponding side of the other triangle.  This is not proportional for all sides, so this is not a dilation.

In the fourth graph, the darker triangle has one side that is 2/3 of the corresponding side of he other triangle, and another side that is 4/6=2/3 of the corresponding side of the other triangle.  Since these are both right triangles, this means the other side, the hypotenuse, will have the same ratio.  Since it is proportional for all sides, this is a dilation.

6.5 Litters

Lower Bound:6.25  L

6.75÷0.275=24.54 or 25  

6.25÷0.285=21.92 or 22

22≤x<25 Joy definitely does have enough soup for 22 people.

The measurement uncertainty in the question gives the range within

which the true value of the given measurement can be found.

Yes, Joy definitely has enough soup to serve 22 people.

Reasons:

Volume of the soup Joy makes = 6.5 L ± 0.5 L = 6,500 mL ± 500 mL

Volume of soup per serving = 280 mL ± 10 mL

Number of people that order the soup = 22 people

Required:

If soup made is enough for 22 people

Solution:

The uncertainty in measurement, u, is expressed as follows;

X ± u

X - u ≤ True value ≤ X + u

Therefore;

Total volume ordered, V₀ = 22 × (280 ± 10) mL = 5,940 mL ≤ V₀ ≤ 6380 mL

The volume of soup made range is given as follows;

(6,500 - 500) mL ≤ M₀ ≤ (6,500 + 500) mL

Which gives;

6,000 mL ≤ M₀ ≤ 7,000 mL

The minimum amount of soup required to serve 22 people = 5,940 mL

The minimum amount of soup Joy makes = 6,000 mL

Therefore, Joy definitely has enough soup to serve 22 people.

it would take 10 3/5 cups of liquid fertilizer

By setting up a proportion and solving, we find that it takes approximately 10.67 cups of liquid fertilizer to make 80 gallons of spray.

The problem deals with a simple rate, or ratio. In this case, the rate is 1 cup of fertilizer per 7.5 gallons of spray. We need to find out how much fertilizer is needed for 80 gallons of spray.

To do this, we need to set up a proportion. On one side of the equation, we'll have the original ratio (1 cup fertilizer : 7.5 gallons spray). On the other side, we'll set up a ratio with the quantity we're trying to find (x cups fertilizer : 80 gallons spray).

So, our equation looks like this:

1 cup / 7.5 gallons = x cups / 80 gallons

To solve for x, we can cross-multiply:

1 cup * 80 gallons = x cups * 7.5 gallons

Which simplifies to:

80 = 7.5x

To isolate x, we divide both sides of the equation by 7.5:

x = 80 / 7.5

Through this, we get that it takes approximately 10.67 cups of liquid fertilizer to make 80 gallons of spray.

so to answer 1/3 of it is left or 16

I believe that the answer is 12.5%

Reason 100% of 80= 80,

So if 80=100%,

then that means 10=x%

Fore it means that, [tex]x=(\frac{10}{80} )*100[/tex]%=12.5%

Answer:

Let the required percentage be x%.

Atq,

3.5(t+6)=7

Use Distributive Property:

3.5t + 21 = 7

Subtract 21 from both sides:

3.5t = -14

Divide both sides by 3.5:

t = -14 / 3.5

t = -4

The answer is A.

To solve for the value of t in the equation 3.5(t+6)=7, we divide both sides by 3.5 and then subtract 6 from both sides, resulting in t = -4.

To find the value of t, we need to solve the equation 3.5(t+6)=7. To do this, we start by dividing both sides of the equation by 3.5 to isolate the t term:

Next, we subtract 6 from both sides to solve for t:

Therefore, the value of t is -4, which corresponds to option A.

We are given function : [tex]M(t)=-t^2+10t[/tex],  where t is the number of hours of after she takes the madicine.

We need to find, how many hours after Elizabeth takes her madicine is the amount of madicine in her blood is highest.

Note: The given function is a quadratic function and a quadratic function represents a parabolic shape.

The highest point on the parabola is the vertex of the parabola.

The x-coordinate of the vertex of the parabola would represent the number hours after Elizabeth takes her madicine is the amount of madicine in her blood is highest.

We know, x-coordinate of the vertex = [tex]\frac{-b}{2a}[/tex]

For the given quadratic function a= -1 and b=10.

Plugging values of a and b in  x-coordinate of the vertex formula, we get

[tex]\frac{-10}{2(-1)}=\frac{-10}{-2}=5[/tex]

Therefore, after 5 hours Elizabeth takes her madicine is the amount of madicine in her blood is highest.

Final answer:

Katie's mistake was in her division calculation. The correct way to find out how many quarter pounders can be made from 5 pounds of meat involves converting pounds to ounces, because you can make 20 quarter pounders when you multiply 5 by 16 to convert to ounces and then divide by 4.

Explanation:

Katie's strategy to divide the total weight of the hamburger meat by the weight of one quarter pounder is a correct approach, but her calculation is incorrect. When you want to determine how many quarter pounders you can make from 5 pounds of hamburger meat, you need to divide the total pounds of hamburger meat by the weight of one quarter pounder, which is 0.25 pounds.

To correct Katie's mistake, you should multiply the weight in pounds by the unit equivalence to get the weight in ounces since we are dealing with a conversion from a larger unit (pounds) to a smaller unit (ounces). Considering the fact that 1 pound equals 16 ounces, the calculation should be:

5 pounds  imes 16 ounces/pound = 80 ounces

After converting the weight to ounces, now compare it to the weight of a quarter pounder in ounces:

0.25 pounds  imes 16 ounces/pound = 4 ounces per quarter pounder

Finally, divide the total number of ounces of hamburger meat by the number of ounces in a quarter pounder to determine how many quarter pounders you can make:

80 ounces/4 ounces per quarter pounder = 20 quarter pounders

Therefore, you can make 20 quarter pounders from 5 pounds of hamburger meat.

"More" stands for adding, and "quotient" stand for division.

Hope this helps!

The equation for '5.2 more than the quotient of h and 3 is w' is 'h/3 + 5.2 = w'. This means h divided by 3, plus 5.2, equals w.

The subject of this question is Mathematics and it involves the creation of a mathematical equation. When the question states 'the quotient of h and 3', it means 'h divided by 3'. So, that part of the equation would be written as 'h/3'.

When the question says '5.2 more than', that indicates you are adding 5.2 to the previous value. So, the whole left side of the equation would be 'h/3 + 5.2'.

Finally, the question states 'is w', which means 'equals w'. So, the entire equation would be written as 'h/3 + 5.2 = w'.

Answer:

Only side length and perimeter of one face

Step-by-step explanation:

Given is a cube with measures given in inches.

For a cube

Volume = s^3 where s = side

Hence volume and side are not having linear relation

Perimeter of 1 face = 4s and area =s^2

Obviously 4s and s^2 cannot have linear relationship as degree is diferent

Surface area of cube = 6s^2 but volume = s^3 both have different degrees of s and hence cannot have linear relation

Area of 1 face = s^2 and surface area = 6s^2

THus we get Surface area = 6(area of 1 face) hence can have linear relationship

side length =s and volume = s^3 so cannot have linear relaionship

Side length =s and perimeter = 4s thus having linear relation.

Hence answers are

side length and perimeter of 1 face

area of 1 face and surface area

A linear relationship is represented by [tex]y = mx + b[/tex], where [tex]m \ne 0[/tex]. The linear relationships are:

Let

[tex]x \to[/tex] side length of the cube

A. Side length and perimeter of 1 face

The perimeter (P) of one face is:

P  = 4 x Side length

[tex]P =4 \times x[/tex]

[tex]P = 4x[/tex]

Compare the above equation to [tex]y = mx + b[/tex].

We can conclude that (a) is a linear relationship

B. Perimeter of 1 face and area of 1 face

We have:

[tex]P = 4x[/tex]

Make x the subject

[tex]x= \frac{P}{4}[/tex]

The area of 1 face is:

[tex]A = x^2[/tex]

Substitute [tex]x= \frac{P}{4}[/tex]

[tex]A = (\frac P4)^2[/tex]

[tex]A = \frac{P^2}{16}[/tex]

Compare the above equation to [tex]y = mx + b[/tex].

We can conclude that (b) is not a linear relationship

C. Surface area and volume

The surface area is:

[tex]S=6x^2[/tex]

The volume is:

[tex]V = x^3[/tex]

Make [tex]x^2[/tex] the subject in [tex]S=6x^2[/tex]

[tex]x^2 = \frac S6[/tex]

So, we have:

[tex]V = x^3[/tex]

[tex]V = \frac S6x[/tex]

Compare the above equation to [tex]y = mx + b[/tex].

We can conclude that (c) is not a linear relationship

D. Area of 1 face and surface area

The surface area is:

[tex]S=6x^2[/tex]

The area of 1 face is:

[tex]A = x^2[/tex]

Substitute [tex]A = x^2[/tex]

[tex]S = 6A[/tex]

Compare the above equation to [tex]y = mx + b[/tex].

We can conclude that (d) is a linear relationship

E. Side length and volume

The volume is:

[tex]V = x^3[/tex]

Compare the above equation to [tex]y = mx + b[/tex].

Alright, so before we can answer this problem we need to go over some basics! For this problem, you'll need to know:

The Triangle Sum theorem states that the interior angles of every triangle must add up to 180 degrees.

Also, corresponding angles are angles that have the same relative position when 2 lines intersect. Therefore, angle I and angle K are corresponding (and as an example, angle J and angle H are corresponding). When lines are parallel (Line HI and Line JK), corresponding angles are equal.

Now that we've covered that, we can use that information to find x!

Let's start with finding angle I since we know it'll be equal to angle X. We also now know that angle H + angle A + angle I = 180. So, plug it in.

56 + 66 + I = 180.

122 + I = 180

Then subtract on both sides:

I = 58.

Since I = X we now know that angle x = 58 degrees.

For this one, an easy way to solve it is to break it down into parts.  First lets convert 5 feet to inches.  

Multiply the number of feet by how many inches are in one foot.  

5 times 12= 60 in

Now just add the like terms

60 in + 2 in= 62 inches.

Now we see that Sarah is 62 inches tall, now we can convert to centimeters the same way.

62 times 2.54= 157.48

So that makes C your answer, Sarah is 157.48 cm tall.

Final answer:

To convert Sarah's height to centimeters, multiply her total height in inches (5 feet and 2 inches, which is 62 inches) by 2.54 cm/inch to get 157.48 centimeters. So, the correct answer is option C, 157.48 centimeters.

Explanation:

To convert Sarah's height from feet and inches to centimeters, you start by converting each measurement to inches, and then convert the total number of inches to centimeters. Sarah is 5 feet and 2 inches tall. One foot is equal to 12 inches, so first we convert her height in feet to inches: 5 feet × 12 inches/foot = 60 inches. Then, add 2 inches to this to get her total height in inches: 60 inches + 2 inches = 62 inches.

Now, convert inches to centimeters using the conversion factor 1 inch = 2.54 centimeters: 62 inches × 2.54 cm/inch = 157.48 centimeters. Therefore, the correct answer is C.
