Step-by-step explanation:

Because it is negative and that is the typical shape for x^4 functions

The graph represents the given function f(x) is attached below

Top right option graph is correct

Given :

The equation of a graph is given by

[tex]f(x)=-2x^4[/tex]

Lets look at the end behavior of the given function f(x)

The leading coefficient is negative  that is -2

The highest exponent is 4 that is the degree is even

When the leading coefficient is negative and degree is even then the graph goes down on both sides  

As x-> ∞, f(x)-> -∞

As x-> -∞, f(x)-> -∞

A student pushes a the same cart with the same 50N of Force over the same distance of 10m, but on this occasion was timed in 5s by their parents who were in a hurry to get home. What was their power? *

Answers

Answer:

100W

Step-by-step explanation:

Power = Work done / time

Work done = force × distance

Work = 50 × 10

Work = 500J

Power = 500 / 5

Power = 100W

What is the image point of (4,5) after a translation left 5 units and down 3 units?

(-1,2)

Step-by-step explanation:

Going left means the x value goes down. In this case, it went to the left 5 spaces. so, all you have to do is subtract 5 from 4 which is -1. When going down on a graph, the y value goes down as well. Subtract 3 from 5 and you get 2. Therefore, the answer is (-1, 2).

Jessica bought 4 packages of birthday invitations for 16.95 per package including tax each package contained 12 birthday invitations one stamp coast 0.44 she plans to split the cost evenly with her mother how much money will Jessica mother need to give to Jessica

Answers

Answer:

Jessica's mum will give her 44.46

Step-by-step explanation:

To solve this, we will first of all need to get the total cost of sending the birthday invitations across. After that, we can now split the cost into two.

Cost of sending birthday invitations:

Package cost = 16.95

Number of packages bought = 4

total sum spent on packages = 4 X 16.95 = 67.8

Each package contains 12 invitations.

There are 4 packages.

Total number of invitations = 12 X 4 = 48 invitations

One stamp cost 0.44.

Putting stamps on all 48 invitations will cost 0.44 X 48 = 21.12

Therefore the total cost will be  the total sum spent on packages +the total sum spent on stamps = 67.8 + 21.12 = 88.92

Her mum has agreed to pay half of this cost which is 88.92 / 2 = 44.46

A basketball team played six games. In those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13. What was the mean difference in game scores over the six games?​

Answers

Mean =sum of observations/ no.of observations

Mean=8+11+7+11+4+13/6

=54/6

mean=9

The mean difference in the game scores over six games is 2.5

What is mean difference?

The mean difference measures the absolute difference between the mean value in two different groups.

Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.

The mean difference of the given data can be calculated using the following formula -

Mean Difference = (∑W / n) - (∑L / n)

Where -

(∑W / n) is the mean of games won.

and

(∑L / n) is the mean of games lost.

(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75

and

(∑L / n) = (11 + 4)/2 = 15/2 = 7.5

Mean difference =  (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5

Therefore, the mean difference in the game scores over six games is 2.5

so like terms for example are 2x and 8x what makes them alike are their variable so if you have a term that is 2x and 7p those are NOT like terms because their variables are different
it’s basically asking you to put together the ones that have the same variable ! for example in #1 you have :
9d + 3y - 5g + 9g - 5 :

The only variable that is seen more than once is g. So you’d combine -5g + 9g

which would give you +4g, therefore:

#1. = 9d + 3y + 4g - 5

you could also use combine like terms calculator on wolframalpha.com, but I would suggest knowing what you’re doing so you can pass your tests!

Answers

Answer:

see below

Step-by-step explanation:

part 1

(-2,1) and (2,1)

Both points have the same y value

The slope is zero since it is a horizontal line and it crosses the y axis at y =1 so the y intercept is (0,1)

part 2

The equation of the line in slope intercept form is

y= mx+b where m is the slope and b is the y intercept

y = 0x+1

y =1

A. 16
B.10
C. 15
D.10

Answers

Answer:

Hi friend! The answer is D. 10

I hope this helps!

Answer:

B) 10

Step-by-step explanation:

Assign variables to each person:

A=Alina's Age

M=Amy's Age

G=Greg's Age

Set up a system of equations given the information:

A=6+G

M=2.5A

M=40

Notice that M is already given, so we can plug that into the second equation:

40=2.5A

16=A

So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:

16=6+G

10=G

So Greg is 10 years old, therefore B is the correct answer.
