A. Both ends go up
B. Both ends go down
C. The left end goes down and the right end goes up
D. The left end goes up and the right end goes down

Which Of The Following Correctly Describes The End Behavior Of The Polynomial Function F(x) = -3x^4+2x^2-xA.

Answers

Answer 1

Answer: B

Step-by-step explanation:

Answer 2

The end behavior of f(x) is that both ends go down. The correct answer is B.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

f(x) = -3x^4+2x^2-x

Now,

we can find the end behavior of f(x) = -3x^4 + 2x^2 - x:

The degree of f(x) is 4, which is even. Therefore, both ends of the graph will either go up or go down.

The leading coefficient of f(x) is -3, which is negative. Therefore, the right end of the graph will go down.

Since both ends have to go in the same direction, and the right end goes down, then the left end must also go down.

Therefore, by the given function the answer will be both ends go down

Find the equation for the line parallel to y=x+3 which has the same y intercept as 2x+3y=12

Answers

Answer:

[tex]y=x+4[/tex]

Step-by-step explanation:

Two parallel lines will have the same slope:

[tex]y=mx+b[/tex]

This is the y-intercept equation, where m is the slope and b is the y-intercept:

[tex]y=x+3[/tex]

The slope is x, or 1x, so the parallel line is also x.

Find the y-intercept:

You do this by taking the equation given and solving for y:

[tex]2x+3y=12[/tex]

Isolate the variable y. Subtract 2x from both sides:

[tex]2x-2x+3y=12-2x\\\\3y=12-2x[/tex]

Isolate y by dividing both sides by 3:

[tex]\frac{3y}{3}=\frac{12}{3}-\frac{2x}{3} \\\\y=4-\frac{2}{3}x[/tex]

Rearrange in slope-intercept form:

[tex]y=-\frac{2}{3}x+ 4[/tex]

The y-intercept of this equation is 4.

Now make the equation using the given information:

Step-by-step explanation:

Hey, there!!

You can solve it simply,

1.

Given,

x= 1 , y=2 , z= 3

To solve:

[tex] = \frac{1}{ {x}^{2} } - \frac{x}{y + z} [/tex]

[tex] = \frac{1}{ {1}^{2} } - \frac{1}{2 + 3} [/tex]

[tex] = 1 - \frac{1}{5} [/tex]

Taking LCM,

[tex] = \frac{5 - 1}{5} [/tex]

Therefore, the final answer is 4/5.

2.

Given,

x= 1 , y= -2, z= -1.

To solve:

[tex] = \frac{1}{ {x}^{2} } - \frac{x}{y + z} [/tex]

[tex] = \frac{1}{ {1}^{2} } - \frac{1}{ - 2 - 1} [/tex]

Taking LCM,

[tex] = \frac{ - 3 - 1}{ - 3} [/tex]

[tex] = \frac{ - 4}{ - 3} [/tex]

Cancelling the minus sign,

[tex] \frac{4}{ 3} [/tex]

is the final answer.

3.

Given,

x= -3, y= -1, z= 4

To solve:

[tex] = \frac{1}{ {x}^{2} } - \frac{x}{y + z} [/tex]

[tex] = \frac{1}{ {( - 3)}^{2} } - \frac{ - 3}{ - 1 + 4} [/tex]

[tex] = \frac{1}{9} - ( - 1)[/tex]

[tex] = \frac{1 + 9}{9} [/tex]

Therefore, the answer is 10/9.

4.

Given,

x= 1/2, y=1, z=1.

To solve:

[tex] = \frac{1}{ {x}^{2} } - \frac{x}{y + z} [/tex]

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

Simplifying them ,

[tex]1 \times \frac{4}{1} - \frac{1}{2} \times 2[/tex]

[tex] = 4 - 1[/tex]

Solve for x 33x+10=5-2x

Answers

Our equation: 33x + 10 = 5 - 2x

Step 1:

To solve for x, we need to remember to isolate the variable (that is our way to solve for x). To do that, we add 2x on the right side of the equation to cancel -2x out. Then, we add 2x on the left of the equation. The equation becomes:

[tex]35x+10=5[/tex]

Step 2:

We subtract 10 from both sides (to cancel out the 10 on the left). Equation:

[tex]35x=-5[/tex]

Step 3: Divide 35 on both sides to get our x value.

trigonometry help ! tysm

Answers

Answer:

a = 50 degrees

b = 85 degrees

c = 95 degrees

d = 82 degrees

e = 125 degrees

f = 95 degrees

g = 110 degrees

h = 35 degrees

Step-by-step explanation:

1: Since the bottom angle is 124, then we see that a + 74 = 124 because they are corresponding angles.

Solve for a, and we get a = 50 degrees.

2. b is equal to 180 - 95 which is 85 degrees, as it is supplementary with the alternate exterior angle of 95 degrees.

c is equal to 180 - 85 which is 95 degrees, as it is supplementary with the alternate exterior angle of 85 degrees.

3. d is 82 degrees, as it is an alternate interior angle with the 82.

e is 125 degrees, as it is corresponding with the 125.

4. If we extend the left slanted line, we see that the exterior angle of the bottom left angle of the triangle is 130 degrees. We know that 130 = 45 + 180 - f, so we solve for f and get 95 degrees.

5. g = 180 - 70 = 110 degrees, as it is supplementary with the alternate exterior of the corresponding angle of 70.

6. We know that the top right angle of the 120 degrees and the 35 degrees triangle is 25 degrees. Then, the bottom left angle is also 25 degrees as they are alternate interior angles. The other unknown angle in the 25 degrees and h triangle is supplementary to 60, so it is 120 degrees.

We know that 25 + h + 120 has to be 180, so we can solve for h and get 35 degrees.

I also need help with 1,000,000 in exponential form , 10x10 , and 10,000 x10 please

Answers

Answer:

Step-by-step explanation:

To convert the value 1,000,000 to an exponential form means we are to write the value in multiples of 10.  Breaking down the values in multiples of 10 will give;

1,000,000 = 10 * 10 * 10 * 10 * 10 * 10 (it is broken down into 6 places because the value contains 6 zeros)

Express in exponential form

1,000,000 = (10 * 10 * 10) * (10 * 10 * 10)

1,000,000 = (10³) * (10³)

1,000,000 = 10³⁺³

1,000,000 = 10⁶

Hence the value 1,000,000 in exponential form is expressed as 1 * 10⁶

For 10 * 10:

10 * 10 = 10¹ * 10¹

10 * 10 = 10¹⁺¹

10 * 10 = 10²

10 * 10 = 1 * 10²

The value of the expression 10*10 in exponential form is 1 * 10²

For 10,000 * 10:

10,000 * 10 = (10*10*10*10) * 10

10,000 * 10 = (10⁴) * 10¹

10,000 * 10 = 10⁴⁺¹

10,000 * 10 = 1 * 10⁵

Hence, The value of the expression 10000*10 in exponential form is 1 * 10⁵

In a hypothesis test, standard error measures ____.

a. variability for the sample data
b. the amount of difference expected just by chance
c. the size of the treatment effect
d. the likelihood of a Type I or Type II error

Answers

Answer:

The correct answer is:

the amount of difference expected just by chance (b)

Step-by-step explanation:

Standard error in hypothesis testing is a measure of how accurately a sample distribution represents a distribution by using standard deviation. For example in a population, the sample mean deviates from the actual mean, the mean deviation is the standard error of the mean, showing the amount of difference between the sample mean and the actual mean, occurring just by chance. Mathematically standard error is represented as:

standard error = (mean deviation) ÷ √(sample size).

standard error is inversely proportional to sample size. The larger the sample size, the smaller the standard error, and vice versa.

Question 7

Answer: A) 15

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

Work Shown:

angle B = angle D = 56

angle C = angle F = 64

The missing angle A adds with B and C to get 180

A+B+C = 180

A = 180-B-C

A = 180-56-64

A = 60

Since angles B and D are congruent, and C and F are congruent, this must mean angle A = angle E. I'm using the angle angle (AA) similarity rule.

angle E = angle A

3x+15 = 60

3x = 60-15

3x = 45

x = 45/3

x = 15

Side note: I'm not sure why your teacher marked angle E as the same as angles C and F.  They should have used another angle marker to indicate that angles A and E are the same.

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

Question 8

Answer: B) 17

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

Work Shown:

Triangle ABC is congruent to triangle EDF. The order is important. We have A first, then B, then C for ABC. Also, we have E first, then D, then F for EDF.

Therefore, we have these three pairings

angle A = angle Eangle B = angle Dangle C = angle F

We'll first need angle C

A+B+C = 180

C = 180-A-B

C = 180-42-108

C = 30

which we'll then solve for x

angle F = angle C

4x-4 = 30

4x = 30+4

4x = 34

x = 34/4

x = 8.5

which doubles to

2x = 2*8.5

2x = 17
