Answer: right side behavior:

              f(x) is Decreasing

             g(x) is Increasing

             h(x) is Increasing

             j(x) is Decreasing

Step-by-step explanation:

The rules for end behavior are based on 2 criteria: Sign of leading coefficient and Degree of polynomial

Sign of leading coefficient (term with greatest exponent):

Degree of polynomial (greatest exponent of polynomial:

f(x) = -2x²

as x → +∞, f(x) → +∞  Decreasing

as x → -∞, f(x) → -∞   Decreasing

g(x) = (x + 2)³

as x → +∞, f(x) → +∞  Increasing

as x → -∞, f(x) → -∞   Decreasing

[tex]h(x)=-1+x^{\frac{1}{2}}\implies h(x)=x^{\frac{1}{2}}-1[/tex]  

as x → +∞, f(x) → +∞  Increasing

as x → -∞, f(x) → -1    Decreasing to -1

[tex]j(x)=\dfrac{1}{2}(-x)^5\implies j(x)=\dfrac{1}{2}(-1)^5(x)^5\implies j(x)=-\dfrac{1}{2}x^5[/tex]

as x → +∞, f(x) → +∞  Decreasing

as x → -∞, f(x) → -∞   Increasing

Answer:

y= 1.6

Step-by-step explanation:

First you make x=0 and then since x=0 you plug it in the equation

11-5y=3+6(0)

11-5y=3

now you swing the 11 to the other side

-5y=3-11

-5y=-8

now you divide -8 by -5 to isolate the variable

y= 1.6

Answer:33=y

Step 64u to 2y you get 66y the. -2+4 and you get 2 which is 66y=2. Now divide 66 by two to get 33=y

Answer:

x+46=1,191 is the equation to solve it you need to do: x+46=1,191

-46 -46 and you would get

x=1145

To find the number of books the library had last year, we can set up an equation: x + 46 = 1,191. By isolating x, we find that the library had 1,145 books last year.

To find the number of books the library had last year, we can set up an equation based on the given information. Let x represent the number of books the library had last year. Since the library acquired another 46 books over the summer, the total number of books is now 1,191. We can set up the equation:

x + 46 = 1,191

To find the value of x, we need to isolate it on one side of the equation. By subtracting 46 from both sides, we get:

x = 1,191 - 46 = 1,145

Therefore, the library had 1,145 books last year.

Answer: 11/4

Step-by-step explanation: When we are trying to find the reciprocal of a fraction, we just flip the fraction so that our numerator is on the bottom and our denominator is on the top.

In this case, we can change 4/11 to 11/4 by flipping the fraction.

Therefore, the reciprocal of 4/11 is 11/4.

Answer:

Weighted mean grade: 81.2

Letter grade: B

Step-by-step explanation:

5 regular tests:

  (63+91+88+84+79) / 5 * 60%

= 405 / 5 * 0.6

= 48.6

Final exam:

86 * 10% = 8.6

Project:

90 * 15% = 13.5

Homework:

70 * 15% = 10.5

So her weighted mean grade is

48.6 + 8.6 + 13.5 + 10.5 = 81.2

The student's weighted mean grade is 81.2, which corresponds to a letter grade of B.

To calculate the student's weighted mean grade, we must apply the provided weights to each component. The five tests count for 60%, the final exam counts for 10%, the project counts for 15% and the homework counts for 15%.

First, find the mean of the five regular test scores: (63 + 91 + 88 + 84 + 79) / 5 = 81.

Then, calculate individual contributions by multiplying the scores by the corresponding weights:

Add these to find the student's weighted mean grade: 48.6 + 8.6 + 13.5 + 10.5 = 81.2. As her grade is above 80, her letter grade would be B.

B. [tex]\frac{-5}{8}+(\frac{5}{8})[/tex]

D. [tex]\frac{-5}{8}-(\frac{-1}{8}+(\frac{-1}{2}))[/tex]

Step-by-step explanation:

- Mike watches a caterpillar climbing on a tree trunk

- He writes the expression [tex]\frac{-5}{8}-(\frac{-1}{8}-\frac{1}{2})[/tex]

- We need to find the equivalent expressions to this expression

A.

∵ The expression [tex]\frac{-5}{8}-(\frac{-1}{8}-\frac{1}{2})[/tex] has a

   common sign negative in the bracket

∴ [tex]\frac{-5}{8}-(-)(\frac{1}{8}+\frac{1}{2})[/tex]

∵ (-)(-) = (+)

∵ The expression [tex]\frac{-5}{8}+(\frac{1}{8}+\frac{1}{2})[/tex] is

   equivalent to the expression [tex]\frac{-5}{8}-(\frac{-1}{8}-\frac{1}{2})[/tex]

B.

∵ In the expression [tex]\frac{-5}{8}-(\frac{-1}{8}-\frac{1}{2})[/tex], lets

  add the two terms in the bracket

  [tex](\frac{-1}{8}-\frac{1}{2})=(\frac{-1}{8}-\frac{1(4)}{2(4)})=(\frac{-1}{8}-\frac{4}{8})=(\frac{-5}{8})[/tex]

∴ The expression = [tex]\frac{-5}{8}-(\frac{-5}{8})[/tex]

∵ (-)(-) = (+)

∴ The expression = [tex]\frac{-5}{8}+(\frac{5}{8})[/tex]

∴ The expression [tex]\frac{-5}{8}+(\frac{5}{8})[/tex] is equivalent to

   the expression [tex]\frac{-5}{8}-(\frac{-1}{8}-\frac{1}{2})[/tex]

D.

∵ In the expression [tex]\frac{-5}{8}-(\frac{-1}{8}-\frac{1}{2})[/tex], we can

  write the bracket as [tex](\frac{-1}{8}-\frac{1}{2})=(\frac{-1}{8}+(\frac{-1}{2}))[/tex]

  because (+)(-) = (-)

∴ The expression [tex]\frac{-5}{8}+(\frac{5}{8})[/tex] is equivalent to

   the expression [tex]\frac{-5}{8}-(\frac{-1}{8}+(\frac{-1}{2}))[/tex]

Answer:

The triangle with vertices with (3, 5), (-2, 6), and (1, 3) is a right triangle.

Solution:

Given that the vertices of triangle are (3, 5), (-2, 6) and (1, 3)

Let us consider A(3, 5) B(-2, 6) C(1, 3)

If the sum of square of distance between two vertices is equal to the square of distance between third vertices, then the triangle is a right angled triangle.

By above definition, we get  

[tex]BC^{2} + CA^{2} = AB^{2}[/tex] ----- eqn 1

Where AB is the distance between vertices A and B

BC is the distance between vertices B and C

CA is the distance between vertices C and D

Distance between any two vertices of a triangle is given as  

[tex]Distance =  \sqrt{\left(x_{2} -x_{1}\right )^{2} + \left(y_{2} -y_{1}\right)^{2}  }[/tex] ------- eqn 2

Step 1:

Let us find the distance between the vertices A(3,5) and B(-2,6)  

By using equation 2, we get  

[tex]x_{1} = 3, x_{2} = -2, y_{1} = 5 \text { and } y_{2} = 6[/tex]

Distance between vertices A and B =[tex]\sqrt{(-2-3)^{2}+(6-5)^{2}}[/tex]

= [tex]\sqrt{(-5)^{2} + (1)^{2}}[/tex]

= [tex]\sqrt{(-5)^{2} + (1)^{2}}[/tex]

= [tex]\sqrt{25+1}[/tex]

= [tex]\sqrt{26} units[/tex]

Step 2:

Let us find the distance between the vertices B(-2,6) and C(1,3)

By using equation 2, we get  

[tex]x_{1} = -2, x_{2} = 1, y_{1} = 6 \text { and } y_{2} = 3[/tex]

Distance between vertices B and C = [tex]\sqrt{(1-(-2))^{2}+(3-6)^{2}}[/tex]

= [tex]\sqrt{(1-(-2))^{2} + (3-6)^{2}}[/tex]

= [tex]\sqrt{3^{2}+9}[/tex]

= [tex]\sqrt{9+9}[/tex]

= [tex]\sqrt{18} \text { units }[/tex]

Step 3:

Let us find the distance between the vertices C(1,3) and D(3,5)

By using equation 2, we get  

[tex]x_{1} = 1, x_{2} = 3, y_{1} = 3 \text { and } y_{2} = 5[/tex]

Distance between the vertices C and A

= [tex]\sqrt{(3-1)^{2} + (5-3)^{2}}[/tex]

= [tex]\sqrt{2^{2} + 2^{2}}[/tex]

= [tex]\sqrt{4+4}[/tex]

= [tex]\sqrt{8} units[/tex]

Step 4:

By using equation 1,

[tex]BC^{2} + CA^{2} = AB^{2}[/tex]

[tex](\sqrt{18})^{2} + (\sqrt{8})^{2} = (\sqrt{26})^{2}[/tex]

18 + 8 = 26

26 = 26

Hence the condition is satisfied. So the given triangle with vertices with (3,5), (-2,6), and (1,3) is a right triangle.  

Step-by-step explanation:

You must first add 20 to all inqualies, leaving u with 0 is greater than or equal to 2x which is also greater than or equal to 40.

Answer:Length: 27m

Step-by-step explanation:

The length of the rectangular field is 27 m.

The area of a rectangle is the product of length and width.

[tex]\rm{ Area\ of\ rectangle = Length \times width[/tex]

As given to us the shape of the field is rectangular, also, the width of the field is 6 m. therefore,

[tex]\rm{Area\ of\ rectangular\ field= Length \times width[/tex]

[tex]162\ m^2 = Length \times 6\ m\\\\\dfrac{162\ m^2}{6\ m} =Length\\\\ Length=\dfrac{162\ m^2}{6\ m}\\\\Length = 27\ m[/tex]

Answer:

[tex](14+12)\times (8+12) > (14\times 12)+(8\times 12)[/tex]

Step-by-step explanation:

First let us evaluate the value of both the expressions.

[tex](14+12)\times (8+12) = 26\times 20 = 520[/tex]

[tex](14\times 12)+(8\times 12) = 168 + 96 = 264[/tex]

a) Hence, Larry's claim that both the expressions are equivalent is wrong.

The evaluation of the expressions have been shown above. The second expression was obtained by swapping the addition and multiplication order and that created the difference.

b) Clearly,

520 > 264

Therefore,

[tex](14+12)\times (8+12) > (14\times 12)+(8\times 12)[/tex]

[tex](14+12)\times (8+12)[/tex] is greater by the expression  [tex](14\times 12)+(8\times 12)[/tex] by a value of 520 - 264 = 256.

Final answer:

Larry is incorrect; the expressions (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are not equivalent. The first expression equals 520, and the second equals 264, with the first being greater by 256.

Explanation:

No, Larry is not correct. The expressions (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are not equivalent because they do not follow the same mathematical rules. The former is calculated using the distributive property of multiplication over addition, while the latter is simply a sum of two products.

To illustrate, let's compute both expressions:

Comparing the results, 520 is evident greater than 264. The difference between them is 256.

The rules of mathematics are universally valid, and incorrect application of these rules can lead to different outcomes, as shown in Larry's claim.

7 is your ansswer

Answer:

25

Step-by-step explanation:

For this, you would use PEMDAS.

PEMDAS stands for parenthesis, exponents, multiplication, division, addition and subtraction. That is the order that you would do those steps.

So first, you would do what is inside the parenthesis, 7+3 which is equal to 10.

So then, you would have { 10• 5-4} ÷2+2.

You next step would be to multiply 10 and 5. This would give you 50.

So your equation would be {50-4}÷2+2

The next step would be to subtract 4 from 50 which would give you 46. And the next step is to divide 46 by 2 which is 23. And the last step would be to add 2 to 23, which is 25.

So, your answer is 25.

5.(2c - 5)

Answer:

Step-by-step explanation:

3(4x + 5) + 2          use the distributive property: a(b + c) = ab + ac

= (3)(4x) + (3)(5) + 2

= 12x + 15 + 2         combine like terms

= 12x + (15 + 2)

= 12x + 17

Answer: 12x + 17

Step-by-step explanation:

First, distribute the 3 to the values within the parentheses.

3 * 4x = 12x

3 * 5 = 15

The expression now becomes 12x + 15 + 2. Now you can combine like terms by adding 15 and 2, since they both have no variable.

12x + 15 + 2

12x + 17

Therefore, the final answer is 12x + 17.

To find the probabilities in this scenario, we will use the information provided in the survey results.

To find the probabilities in this scenario, we will use the information provided in the survey results. Let's go through each question one by one:

a. The prisoner does not take classes: We can find this probability by adding the number of prisoners who do not take high school or college classes and dividing it by the total number of prisoners. In this case, the number of prisoners who do not take classes is 107 + 32 = 139. The total number of prisoners is 107 + 450 + 32 + 367 = 956. So, the probability is 139/956.

b. The prisoner is under 30 and is taking either a high school class or a college class: We can find this probability by adding the number of prisoners who are under 30 and taking high school or college classes and dividing it by the total number of prisoners. In this case, the number of prisoners who are under 30 and taking high school or college classes is 107 + 450 = 557. So, the probability is 557/956.

c. The prisoner is over 30 and is taking either a high school class or a college class: We can find this probability by adding the number of prisoners who are over 30 and taking high school or college classes and dividing it by the total number of prisoners. In this case, the number of prisoners who are over 30 and taking high school or college classes is 32 + 367 = 399. So, the probability is 399/956.
