Step-by-step explanation:

4b² + 8b + 3

Consider the factors of the product of the coefficient of the b² term and the constant term which sum to give the coefficient of the b- term.

product = 4 × 3 = 12 and sum = + 8

The factors are 2 and 6

Use these factors to split the b- term

4b² + 2b + 6b + 3 ( factor the first/second and third/fourth terms )

= 2b(2b + 1) + 3(2b + 1) ← factor out (2b + 1) from each term

= (2b + 1)(2b + 3)

Answer:

-3/2

Step-by-step explanation:

choose an x variable with it's corresponding y variable from the table.

for example -4, 19

then choose another one,

for example 0, 13

-4 will be the x1 and 19 will be y1 (-4=x1) (19=y1)

the second pair,

0 will be x2 and 13 will be y2 (0=x2) (13=y2)

then you need to subtract y1 from y2:       13 - 19 = (-6)

then you need to subtract x1 from x2:       0 - (-4) = 4

now you have y = (-6)

and x = 4

and since rise over run, aka y = rise, x = run, you put y over x. (divide)

y/x   -6/4  simplify = -3/2

Answer:

$16

Step-by-step explanation:

1. Simplify 12/45 which is now 4/15. Now we know $4 is made every 15 minutes.

2. Divide into 60(minutes) by the the 15. So 60÷15=4. Now we the number of times 15 can be divided into 60.

3. Multiply the ratio 4/15 by 4/4 to see how much is made in an hour. 4x4/15×4=16/60.

$16 is made in 60 minutes (1 hour).

Answer:

2450

Step-by-step explanation:

52+18=70

86-41=45

70×45=2450

The product of the sum of 52 and 18 and the difference of 86 and 41 is 3150.

Given is the sum of 52 and 18 and the difference of 86 and 41.

We can write the expression as -

{x} = (52 + 18) x (86 - 41)

{x} = 70 x 45

{x} = 3150

Therefore, the product of the sum of 52 and 18 and the difference of 86 and 41 is 3150.

Step-by-step explanation:

Answer:

10 headbands = $12.50

Step-by-step explanation:

1) The function equation that represents the relationship between the number of headbands sold (x) and the commission earned (S) is: S = 1.25 * x. For each headband sold, you earn a commission of $1.25.

2) The point (5, 6.5) is not a solution for the function. When you sell 5 headbands, the commission earned should be $6.25, not $6.5.

3) A solution that does not appear in the table is (10, 12.50). Selling 10 headbands would result in a commission of $12.50.

1.

To complete the table, we can use the given information that for each headband sold, you earn a commission of $1.25.

Function Rule (Commission S): The function equation that represents the relationship between the number of headbands sold (x) and the commission earned (S) is:

S = 1.25 * x

Now, we can use this function to fill in the table:

Number of Headbands Sold (x) | Commission (S)

0 | 0 * 1.25 = $0 (No commission earned for 0 headbands sold)

1 | 1 * 1.25 = $1.25

2 | 2 * 1.25 = $2.50

3 | 3 * 1.25 = $3.75

7 | 7 * 1.25 = $8.75

15 | 15 * 1.25 = $18.75

32.50 | 32.50 * 1.25 = $40.625 (The value in the table seems to be a typo, it should be 32.50 * 1.25 = $40.625)

2.

To check if (5, 6.5) is a solution for the function, we need to see if the commission earned (S) matches with the given number of headbands sold (x) for that point.

Given (x, S) = (5, 6.5)

Using the function rule: S = 1.25 * x

S = 1.25 * 5 = 6.25

The commission earned (S) is $6.25, not $6.5. Therefore, (5, 6.5) is not a solution for the function as the value of S does not match.

3.

To identify a solution that does not appear in the table, we can select any number of headbands sold (x) and calculate the corresponding commission (S) using the function rule.

For example, let's choose x = 10:

Using the function rule: S = 1.25 * 10 = $12.50

So, a solution that does not appear in the table is (10, 12.50), where 10 headbands sold results in a $12.50 commission.

#SPJ2

Answer: $135

Explanation: To find how much 15 pizzas will cost, first we have to find out how much just one pizza will cost. To do this, you have to divide both the number of pizzas (8) and also the price for those 8 pizzas ($72) by the number of pizzas (8 again). When you do this you get the price of one pizza. Then you multiply the price of one pizza by the amount of pizzas you actually need to find the value for (15). This is a lot to explain but don't lose hope! Let me show you step by step and it'll make more sense.

Step 1) Divide both the amount of pizzas and the cost of that many pizzas

8 ÷ 8 = 1

72 ÷ 8 = 9

This means that one pizza costs 9 dollars.

Step 2) Multiply the cost of one pizza by 15 (the amt of pizzas you need to find the cost for)

15 × 9 = 135

135 is the cost for 15 pizzas. I hope this helps you!

Answer:

Step-by-step explanation:

Remark

I really don't know what to write to these questions. I can never tell what the problem is. Perhaps it is right at the very beginning. You have to recognize what is taking place. In problem 9, the easiest point to follow is H going to H'. Do you see what is happening? H is sitting on the x axis and then something happens to it and behold, it is now sitting on the y axis. So it has rotated 90 degrees but which way?

Take your finger or a pencil and put it on H. Then make a circular motion to get to H'. You are going clockwise. (keep going in that direction till you wind up where you started. You are going in the direction of one of those old fashioned clocks. Now the trick in a rotation is if you can figure out what one point is doing, you know what all points are doing on the given figure.

So the translation is 90 degrees clockwise. That means the following rule must be operating

(x,y) ===> (y, - x)

H(-3,0) ===> H'(0, - - 3) = H'(0,3)

I(-2,1) =====>I'(1, - - 2) = H'(1,2)

J(0,1) =====>J'(1,0)

G(-3,-3)====>G'(-3, --3) = G'(-3,3)

11

At first you may think that this is a translation of some kind. I thought so at first. D and D' certainly look that way and C and C' also look that way. But B and E are not well behaved. You are looking at a 180 degree rotation

The rule you need here is (x,y) becomes (-x , - y)

I'll leave C and D to you and do one of the B and E

E(3,5)=E'(-3 , - 5)

  9) (x, y) ⇒ (y, -x) . . . . rotation 90° CW

  11) (x, y) ⇒ (-x, -y) . . . rotation 180°

Step-by-step explanation:

9) Distance from the origin to an image point is the same as to the preimage point, but the direction is changed by 90° in the CW direction. For example, J is north of the origin, but J' is east, a direction change of 90° CW.

The transformation describing a 90° CW rotation is the rule ...

  (x, y) ⇒ (y, -x)

11) Distance and direction to each image point from the origin are equal and opposite of distance and direction to the preimage point. The figure has been rotated 180°. The corresponding rule is ...

Step-by-step explanation:

Answer:

the answer is b.6

-------------------------

Using the binomial distribution, we find that:

a) There is a 0.648 = 64.8% probability that there will be at least two hurricanes from which the home will experience no damage before the second hurricane from which the home will experience damage.

b) There is a 0.1728 = 17.28% probability that the home will experience its second damage from the fourth hurricane, given that the home has not experienced two damages from the first two hurricanes.

c) The mode is of 7.5 hurricanes.

For each hurricane, there are only two possible outcomes. Either it causes damage, or it does not. The probability of the home experiencing damage from a hurricane is independent of any other hurricane, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

It gives the probability of exactly x successes on n trials, with p probability.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]  

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The mode of the number of trials needed for q successes is given by:

[tex]M = \frac{q}{p}}[/tex]

In this problem, there is a 0.4 probability of experiencing damage from a hurricane, thus [tex]p = 0.4[/tex].

Item a:

This is the probability of at most 1 damage in 3 hurricanes, which is:

[tex]P(X \leq 1) = P(X = 0) + P(X = 1)[/tex]

With [tex]n = 3[/tex].

In which

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{3,0}.(0.4)^{0}.(0.6)^{3} = 0.216[/tex]

[tex]P(X = 1) = C_{3,1}.(0.4)^{1}.(0.6)^{2} = 0.432[/tex]

Then

[tex]P(X \leq 1) = P(X = 0) + P(X = 1) = 0.216 + 0.432 = 0.648[/tex]

0.648 = 64.8% probability that there will be at least two hurricanes from which the home will experience no damage before the second hurricane from which the home will experience damage.

Item b:

Then

[tex]0.432(0.4) = 0.1728[/tex]

0.1728 = 17.28% probability that the home will experience its second damage from the fourth hurricane, given that the home has not experienced two damages from the first two hurricanes.

Item c:

Then:

[tex]M = \frac{3}{0.4}} = 7.5[/tex]

The mode is of 7.5 hurricanes.

Answer:

Step-by-step explanation:

w = width

3w = three times the width

3w-7=7 feet less than three times the width

l = length = 3w-7

A=length × width (lw)

66 = (3w-7) × (w)

66 = 3w^2 - 7w

3w^2 - 7w -66 =0

factor

3 = 3 × 1 and 66 = 6 × 11,

6 × 3 = 18,  11 × 1 = 11,  18 - 11 = 7

(3w   )(w   )=0 so far

(3w   )(w  6)=0 so far

(3w   11)(w   6)=0 so far

(3w+11)(w-6)=0

w-6=0

w=6

3w=3*6=18

3w-7=3*6-7=18-7=11

w=6 feet

l=11 feet

Problem 11

Answer: Not a function

Why not? Because it fails the vertical line test. It is possible to draw a single straight vertical line through more than one point on this blue curve.

Put another way: An input like x = 2 produces more than one output (y = 2 and y = 4 at the same time). If we wanted a function, we need any given input in the domain to produce exactly one and only one output.

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

Problem 15

Answers:

Explanation:

The domain is the set of allowed x values. The left-most point on the blue curve is when x = -4, which is the smallest item allowed in the domain. The largest value allowed is x = 2, as this occurs at the right-most point on the blue curve. Therefore, our domain here is [tex]-4 \le x \le 2[/tex]

The range is similar, but we focus on y values this time. The lowest the graph goes is y = 2, and the highest it goes is y = 6. So [tex]2 \le y \le 6[/tex] represents the range of possible y outputs.

For both the domain and range, both endpoints are included.

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

Problem 16

Answers:

Explanation:

We follow the same idea as before. This time however, we have open holes which means that we do not include the endpoints.

The domain is [tex]2 < x < 7[/tex] since the curve spans from x = 2 to x = 7, excluding both of those x values. The range is [tex]1 < y < 6[/tex] for similar reasoning.

Notice how both problems 15 and 16 are functions because they pass the vertical line test. It is not possible to draw a single vertical line through more than one point on either blue curve.
