factor the polynomial f(x) = X^3+5x^2+7X+3

The answer is (X+1)^2(x+3)

**Answer:**

**Step-by-step explanation:**

Third level polynomial, so three factors

Only whole numbers, so only whole number x⁰ factors

whole number factors of 3 are 1,1,3 or 1,-1,-3 or -1,-1,3

let's try (x + 3) as a factor

x² + 2x + 1

x + 3 | x³ + 5x² + 7x + 3

- x³ + 3x²

2x² + 7x

- 2x² + 6x

x + 3

- x + 3

0

so (x + 3) is a factor and x² + 2x + 1 factors to (x + 1)²

x³ + 5x² + 7x + 3 =** (x + 3)(x + 1)(x + 1)**

what is the value of f(-8) in f(x)=-3x-9

The value will be .......**1****5**.......

f(x) = -3x - 9

Now, substitute -8 in the place of x.

f(x) = -3x - 9

f(-8) = - 3(-8) - 9

f(-8) = 24 - 9

f(-8) = 15

Answer for the first question: There are 13 pieces of pie left.

Step-by-step explanation: So there are 3 pieces of apple pie left, there are 4 pieces of cherry pie left, and there are 6 pieces of pumpkin pie left. 3 + 4 + 6 = 13.

3/8 = 3 pieces because each fraction in this one equals one piece. So the numerator is how many left.

1/2= 4 because you just divide 8 by 2.

3/4 = 2 because you can multiply the fraction by 2 and get 6/8. Then the numerator is how many that's left.

Therefore, there are 13 pieces of pie left.

1. First, let's have the pieces have the same denominator: 8!

3/8 is already fine

1/2 = 4/8

3/4 = 6/8

Now add up the numerators: 13 pieces were eaten.

Since there are 3 pies, there's 24 pieces total

24 - 13 = 11

**11 pieces are left over**

2. First, 3/4 x 6 = 4.5

1 1/2 x 5 = 7.5

4.5 + 7.5 = 12

-5 + 12 = 7

**At 5:00 pm, it was 7 degrees.**

Hope this helps!

A container 2/3 gallon of apple juice. If four people from the cross-country Tracy team share the juice equally how much juice will each team member get?

**Answer:**

**Step-by-step explanation:**

Total juice = 2/3 of container

Total people = 4

Juice for 1 people = 2/3/(4)

=> 2/3 × 1/4

Estimate the distance you can travel in 3 hours 20 minutes if you drive on average 49 miles per hour. Round your answer to the nearest mile.

**Answer:**

163 miles

**Step-by-step explanation:**

set up a ratio based on 49 miles in 1 hour (60 minutes):

let 'd' = distance in 3hrs, 20 min

3hrs, 20 min = 200 minutes

49/60 = d/200

cross-multiply:

60d = 9800

d = 163.3

The **distance **you can travel in 3 **hours **20 **minutes **if you drive on average 49 **miles **per hour will be 163.33 **miles**.

The **distance **covered by the particle or the **body **in an hour is called speed. It is a **scalar quantity**. It is the ratio of **distance **to time.

We know that the **speed **formula

Speed = Distance/Time

The **speed **of the vehicle is 49 **miles **per hour. And the **time **is 3 hours 20 **minutes**.

Convert the time **completely hours**. Then we have

T = 3 + 20/60

T = 3.33 hours

The **distance **you can travel in 3 **hours **20 **minutes **if you drive on average 49 **miles **per hour will be

D = 49 x 3.33

D = 163.33 miles

The **distance **you can travel in 3 **hours **20 **minutes **if you drive on average 49 **miles **per hour will be 163.33 **miles**.

11. A bank teller has a total of 124 bills in five-dollar bills and ten-dollar bills. The total value of the

money is $840. How many ten-dollar bills does she have

**Answer:**

44 ten-dollar bills

**Step-by-step explanation:**

Assume that all 124 bills are ten-dollar bills,

124 x $10 = $1240

Total Value of Money : $840

$1240 - $840 = $400

There are $400 worth of five-dollar bills,

$400 / 5 = 80 (The number of five-dollar bills)

Therfore the number of ten-dollar bills,

124 - 80 = 44

Let's check:

44 x $10 = $440

80 x $5 = $400

Total = $440 + $400

= $840

The function rule is y=x+2

**Answer:**

**Step-by-step explanation:**

There are multiple ways to do this, but I'll go with the first one I learned and the simplest.

So the standard equation for linear functions is y=kx+b, right? Take two groups of (x,y) and plug them in.

Eg. (Taking (-3,-1) and (1,3)) -1=-3k+b and 3=k+b

By solving the above system, you get k=1, b=2. Put those into the standard equation and you get y=x+2, which is your answer.

A pipe that is 165 feet long is cut into three parts whose lengths are in the ratio 2 : 5 : 8. Find the length of the longest piece. Longest piece: 2 feet

**Answer:**

88 ft

**Step-by-step explanation:**

Let's say the shortest piece has length 2x, so the medium piece has length 5x and the longest piece has length 8x. Added together, they equal 165, so

2x + 5x + 8x = 165

15x = 165

divide both sides by 15 to isolate x

x = 11

8x = longest piece = 88 ft

40% of athletes have tattoos and get into fights with other athletes. 50% of athletes get into fights with other athletes. What is the probability that an athlete that is getting into a fight has a tattoo

The **probability **that an athlete that is getting into a **fight **has a **tattoo **is 0.80

Let the **events **be represented as:

So, the **probabilities **are given as:

[tex]P(A\ n\ B) = 40\%[/tex]

[tex]P(A) = 50\%[/tex]

The **probability **that an athlete that is getting into a **fight **has a **tattoo **is represented as: P(B | A)

So, we have:

[tex]P(B | A) = \frac{P(A\ n\ B)}{P(A)}[/tex]

Substitute known values

[tex]P(B | A) = \frac{40\%}{50\%}[/tex]

Cancel out the **percentages**

[tex]P(B | A) = \frac{40}{50}[/tex]

Divide 40 by 50

[tex]P(B | A) = 0.80[/tex]

Hence, the **probability **that an athlete that is getting into a **fight **has a **tattoo **is 0.80

What is the slope of the line tangent to the graph of y = (9x^2)/(x+2) at x = 1 ?

Using **derivatives**, it is found that the **slope **of the line tangent to the graph of y at x = 1 is of **5.**

The **equation **is:

[tex]y(x) = \frac{9x^2}{x + 2}[/tex]

The **slope **of the line tangent to the graph of y at x = 1 is [tex]y^{\prime}(1)[/tex].

Applying the **quotient rule**, we have that:

[tex]y^{\prime}(x) = \frac{[9x^2]^{\prime}(x + 2) - [x + 2]^{\prime}(9x^2)}{(x + 2)^2}[/tex]

[tex]y^{\prime}(x) = \frac{18x(x + 2) - 9x^2}{(x + 2)^2}[/tex]

[tex]y^{\prime}(x) = \frac{9x^2 + 36x}{(x + 2)^2}[/tex]

Then, when **x = 1:**

[tex]y^{\prime}(1) = \frac{9(1)^2 + 36(1)}{(1 + 2)^2} = \frac{45}{9} = 5[/tex]

The **slope **of the line tangent to the graph of y at x = 1 is of **5.**

YOU’RE GETTING A BRAINLIST IF YOU ANSWER THESE:

If you and I meet halfway between the fountain and the restrooms what are the coordinates of our meeting place?

If my cat and your dog meet halfway between the ball field and the swings what are the coordinates of their meeting place?

Now to the nearest yard how far are you and I to our pets after arriving to our meeting place?

**Answer:**

**Step-by-step explanation:**

Question 1

Answer:----------------------

Explanation:

The x coordinates of the points for the restrooms and fountain are -2 and 4 in that order. Add up those values and divide by 2

(-2+4)/2 = 2/2 = 1

The midpoint of -2 and 4 on the number line is the value 1. So if the restrooms and fountain were on the x axis and at -2 and 4 respectively, then the midway point is 1 on that same number line. Note: The value 1 is exactly 3 units away from -2 and 4.

We'll use this idea for the y coordinates as well. Add them up, then divide by 2.

Add: 4+(-5) = -1

Divide by two: -1/2 = -0.5

The y coordinate of the midpoint is -0.5

Overall, the midpoint between the restrooms and fountain is the point** (1, -0.5)**

For more info, check out the midpoint formula.

====================================================

Question 2

Answer:----------------------

Explanation:

We'll use the same idea as before. This time we focus on the locations of the swings and ball field only.

Add the x coordinates for each point: -5+5 = 0

Divide in half: 0/2 = 0

The x coordinate of the midpoint is 0

Repeat for the y coordinates.

Add: 5+(-4) = 1

Cut in half: 1/2 = 0.5

The y coordinate of the midpoint is 0.5

We get the midpoint **(0, 0.5) **which is where the two pets meet.

====================================================

Question 3

Answer: Approximately 1 yard----------------------

Explanation:

Apply the distance formula for the results of the previous two questions.

So we'll apply the midpoint formula for the points (1, -0.5) and (0, 0.5)

[tex]d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(1-0)^2+(-0.5-0.5)^2}\\\\d = \sqrt{(1)^2+(-1)^2}\\\\d = \sqrt{1+1}\\\\d = \sqrt{2}\\\\d \approx 1.414\\\\d \approx 1\\\\[/tex]
