Answer 1

Answer:

- 9 and 28

Step-by-step explanation:

substitute the given values for x, y, z into the expressions

1

- (3 - 2) - 4(3 + 1) + 1 + (2(3) + 2)

= - 1 - 4(4) + 1 + 6 + 2

= - 1 - 16 + 9

= - 17 + 9

= - 8

2

4(2)  - 6(- 3 + 1²) + 4(2)

= 8 - 6(- 3 + 1) + 8

= 8 - 6(- 2) + 8

= 8 + 12 + 8

= 28

Answer 2

Answer:

-8 28

Step-by-step explanation:

You want to evaluate these expressions when (x, y, z) = (3, 2, 1).

-(x -y) -4(x +z) +z +(2x +y)4y -6(-x +z²) +4y

Simplify

We find it easier to evaluate the expression when it is simplified to a form that minimizes that amount arithmetic we need to do. So, our evaluation does that first. Then the corresponding values are put where the variables are in the expression, and the arithmetic is carried out.

1.

Simplifying, we find the sum to be ...

  -x +y -4x -4z +z +2x +y = x(-1-4+2) +y(1+1) +z(-4+1)

  = -3x +2y -3z = 2y -3(x +z)

  = 2(2) -3(3 +1) = 4 -12

  = -8

2.

Simplifying, we find the sum to be ...

  4y +6x -6z² +4y

  = 6x +8y -6z²

  = 6(x -z²) +8y

  = 6(3 -1²) +8(2) = 12 +16

  = 28

A sales associate earned a commission of $26.40 for sales totaling $220.00.

Which proportion could be used to find the commission amount for sales totaling $515.00?


26.4/220=x/515

x/26.4=220/515

220/x=26.4/515

26.4/220=515/x

Answers

Answer:

The first option

Step-by-step explanation:

Hello!

We want to find the correct proportion. 26.40/220 is the correct proportion for the amount earned because the associate earned $26.40 out of $220. The term "out of" is division.

Now, we have to match the format, where the commissions are the numerator, and the total is the denominator.

So we have x in the numerator (the same as 26.40) and 515 in the denominator (the same as 220).

This would be the first option : [tex]\frac{26.40}{220} = \frac{x}{515}[/tex]

Let's use ratios

Let that be x

[tex]\\ \rm\rightarrowtail \dfrac{26.40}{220}=\dfrac{x}{515}[/tex]

[tex]\\ \rm\rightarrowtail 0.12=x/515[/tex]

[tex]\\ \rm\rightarrowtail x=515(0.12)[/tex]

[tex]\\ \rm\rightarrowtail x=61.8[/tex]

Answers

Answer:

Option C

Step-by-step explanation:

Given the following question:

Using the process of elimination, we can find the answer:

It's not option A, because in order for a table to be a linear function the change of x, and the change of y have to be constant. In this case our change in y goes through -2, to -1. Which means option A is not a linear function.

It's not option A because again in order for a table to be a linear function the change of x and the change of y have to be constant. In this case our change of x is constant but our change in y isn't.

It's not option D because in order to have a linear function, you have to be able to rewrite the function into slope intercept (y = mx + b) in this case we only have one real number which is 12, while having our x, and y variable. Which means option D isn't a function.

Which leaves option C or "4x + 3y = 12" which is your answer, because it can be rewritten in slope intercept form.

Hope this helps.

The mean of a dataset is the average of the dataset

The mean of all the sample data is 4.67 hours

How to determine the mean

The datasets are given as:

Week A: 6, 5, 5, 6, 4, 6, 8, 5, 2, 6

Week B: 0, 6, 6, 5, 4, 5, 6, 3, 4, 9

Week C: 4, 5, 6, 4, 3, 2, 2, 3, 12, 1

The mean of a dataset is:

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

So, we have:

Week A

[tex]\bar x_A = \frac{6+ 5+ 5+ 6+ 4+ 6+ 8+ 5+ 2+ 6 }{10}[/tex]

[tex]\bar x_A =5.3[/tex]

Week B

[tex]\bar x_B = \frac{0+ 6+ 6+ 5+ 4+ 5+ 6+ 3+ 4+ 9}{10}[/tex]

[tex]\bar x_B = 4.8[/tex]

Week C:

[tex]\bar x_C = \frac{4+ 5+ 6+ 4+ 3+ 2+ 2+ 3+ 12+ 1}{10}[/tex]

[tex]\bar x_C = 4.2[/tex]

Calculate the mean for the three weeks

[tex]\bar x = \frac{5.3 + 4.8 + 4.2}{3}[/tex]

[tex]\bar x = 4.76[/tex]

Hence, the mean of all the sample data is 4.67 hours

Step-by-step explanation:

a1 = -2 r=-2 Sn=22 Determine the number of terms of n in the series

Answers

A series can be an arithmetic series or geometric series

The series is undefined

How to determine the number of terms?

The given parameters about the geometric series are:

a1 = -2 --- the first term

r=-2 --- the common ratio

Sn=22 --- the sum of n terms

The sum of n terms of a geometric series is represented as:

[tex]S_n = \frac{a(r^n - 1)}{(r-1)}[/tex]

Substitute known values

[tex]22 = \frac{-2((-2)^n -1)}{(-2-1)}[/tex]

This gives

[tex]22 = \frac{-2((-2)^n -1)}{(-3)}[/tex]

Divide both sides by -2

[tex]-11 = \frac{((-2)^n -1)}{(-3)}[/tex]

Multiply both sides by -3

[tex]33 = (-2)^n -1[/tex]

Add 1 to both sides

[tex](-2)^n = 34[/tex]

Take the natural logarithm of both sides

[tex]n\ln(-2) = \ln(34)[/tex]

Solve for n

[tex]n= \frac{\ln(34)}{\ln(-2) }[/tex]

The above number is a complex number.

Hence, the series is undefined

for p(x) = 5x^3-2x^2+3x-6.is x=-1 is a root of p(x)?is x=1 is a root of p(x)​

Answers

Answer:

just x = 1 is a root.

Step-by-step explanation:

p(-1) = 5(-1)³ - 2(-1)² + 3(-1) - 6 = -5 - 2 - 3 - 6 = -26

so x= -1 isn't root for p(x)

p(1) = 5(1)³ - 2(1)² + 3(1) - 6= 5 - 2 + 3 - 6= 0

so x = 1 is a root for p(x)

Using complementary angles, it is found that the solution to the trigonometric equation is of x = 20.

Complementary angles are two angles whose measures add to 90º.

[tex]\sin{a} = \cos{b}[/tex]

In this problem, the equation is:
