Which functions have graphs that are steeper than the graph of f(x)=−3x^2?

Select each correct answer.

h(x)=−2x^2

g(x)=−4x^2

k(x)=3x^2

m(x)=4x^2

j(x)=2x^2

Need help asap please

I think it is k(x)=3x^2 and j(x)=2x^2 Can anyone tell me if i am correct.


Answers

Answer 1

Answer:

g(x)=−4x^2  and m(x)=4x^2

Step-by-step explanation:

A horizontal stretch or shrink happens when you multiply the parent function (in this case f(x) = x²) by a number.  If this number is between 0 and 1, the graph will be stretched horizontally.  If this number is greater than 1, the graph will be shrunk horizontally.  If the number is between -1 and 0, the graph will be stretched horizontally and flipped; if the number is less than -1, the graph will be shrunk horizontally and flipped.

The graphs that are horizontally shrunk are steeper than the others.  This is m(x)=4x^2  and g(x) = -4x^2.

Answer 2

   If the parent function f(x) = x is stretched vertically by a scale factor 'k', image function will be,

   g(x) = kf(x)

It's inverted form will be,

  h(x) = -kx

Functions given in options (2) and (4) will be more steeper than function 'f'.

  Given function is f(x) = -3x²

Functions having scale factor 'k' more than 3 will be more stretched vertically.

Hence, functions having k > 3 will be more steeper.

From the given options, g(x) = -4x², m(x) = 4x² have coefficient 'k' greater than 3.

Therefore, functions 'g' and 'm' will be more steeper than function 'f'.

      Options (2) and (4) are the correct options.

The Sharks have played 5 basketball games this season. Their scores are 65, 63, 67, 60, and 65. If they only score 30 points in their next game, what will happen to their MEDIAN score?

Answers

the median of the scores now is:

60 , 63 , 65 , 65 ,67

Median = 65

if the score 30, the median would be

30, 60 , 63 , 65 , 65 ,67

Median: 63 +65 = 128/2 = 64

The Median drops by 1

In their first five games their median would be 67 because it is the middle number. But if they score 30 points then you would have to add 67+60 and get 127. Then you divide 127 by 2 and get 63.5. The median would be changed to 63.5.

An architect makes a blueprint with a scale of one fourth inch equals 2 ft. Which will be the dimensions of the drawing of a warehouse room measuring 60 ft by 100 ft? Answer Options with 5 options A. 15 inches ''by 25 inches   '' B. 7.5 inches ''by 12.5 inches   '' C. 120 inches ''by 200 inches   '' D. 480 inches ''by 800 inches   '' E. 30 inches ''by 50 inches   ''

Answers

Facts: scale .25"=2'
room 60'×100'

Equation: 60/2=30×.25=7.5
100/2=50×.25=10.5

Answer: B

The new dimension in inches is 7.5 inches by 12.45 inches. Hence, option B is correct.

What is ratio?

The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.

As per the given information in the question,

One fourth inch equal to 2ft.

Mathematically,

1/4 inch = 2ft

0.25 inch = 2ft

The given dimensions are 60 ft by 100 ft.

Now,

0.25 inch = 2ft

x inch = 60 ft

2x = (0.25 × 60)

x = 15/2

x = 7.5 inches

Then,

0.25 inch = 2ft

y inch = 100 ft

2y = 100 × 0.25

y = 25/2

y = 12.45 inches

The sun produces 3.8x10^27 joules of energy per second. How much energy is produced in a year? (Note: a year is approximately 31,000,000 seconds.) Put it in scientific form.

Answers

If you're talking about the 'scientific notation', the answer would be (3.800000000000000000000000000, 26 zeroes.) 

Answer: About [tex]\approx1.178\times10^{35}[/tex]

Step-by-step explanation:

Given : The sun produces[tex]3.8\times10^27[/tex] joules of energy per second.

It is also given that a year is approximately 31,000,000 seconds.

In scientific notation , it can be written as [tex]3.1\times10^7[/tex]

Then , the amount of energy is produced in a year will be :-

[tex]3.8\times10^{27}\times3.1\times\times10^7\\\\=3.8\times3.1\times10^{27}\times10^7\\\\=11.78\times10^{27+7}\\\\=11.78\times10^{34}=1.178\times10^{35}[/tex]

Hence,  the amount of energy is produced in a year  [tex]\approx1.178\times10^{35}[/tex]

How do I combine like terms? For example one problem is 32y + 5y = please explain.

Answers

Step 1: Combine the coefficients. 32y + 5y are coefficients. (means have the same letter basically)
SO 32y + 5y= 37y
You can't combine oranges with apples, just oranges with oranges and apples with apples. Think about it that way.

In this specific problem, the only thing you need to do is add those numbers together as they are like terms (both have y), you'd get 37y.

With a problem like 2 + 5x + 3 + x, you'd have to identify which are like terms and which aren't. The x's go together, and 2 and 3 go together. The result would be 5 + 6x, since you can't combine x and 5.

In point-slope form, the equation of the line is
.. y -k = m(x -h) . . . . . . for slope m and point (h, k)

You have m = -7/2 and (h, k) = (8, -28), so the point-slope equation is
.. y -(-28) = (-7/2)*(x -8)
.. y +28 = (-7/2)x +28 . . . . simplify
.. y = (-7/2)x . . . . . . . . . . . . subtract 28

Carmen, Reuben, and Bob have a total of $133 in their wallets. Bob has 3 times what Reuben has. Carmen has $8 more than Reuben. How much does each have?

Answers

So you will want to form a few equations. The first one is:
C+R+B=133
Then you will want to form an equation for Bob:
B=3R
Then, another for Carmen
C=R+8

Knowing this information, you can plug each in, solving for R.

R+8+R+3R=133      Now Solve
5R+8=133               Subtract 8 from both sides
5R=125                   Divide 5 from both sides
R=25                       Now substitute R in for Carmen and Bob equations.

R=25                        Reuben has $25
C=8+25                    Add
C=33                        Carmen has $33
B=3(25)                    Multiply
B=75                        Bob has $75

Check answer:

25+33+75=133
133=133

Find the length of each side

This can only be answered if we know that segments BG, CF, and DE are parallel. I don't see that written anywhere. I'll assume that is given.

To find GF:

AG is to AB as GF is to BC

AG/AB = GF/BC

20/16 = GF/12

5/4 = GF/12

4GF = 5 * 12

4GF = 60

GF = 15

To find FE:

AG is to AB as FE is to CD

AG/AB = FE/CD

D. 729

Answers

Answer:

72.9, The answer is 72.9...


Final answer:

The product of 4.5, -9, and -1.8 once simplified is 72.9, due to the rule that multiplication of two negative numbers gives a positive result.

Explanation:

The question asks you to simplify the multiplication of the numbers 4.5, -9, and -1.8. To answer this, we first multiply 4.5 and -9 to get -40.5. We then multiply -40.5 by -1.8. This is the basic principle of arithmetic which states that multiplication should be implemented from left to right.

Remember that multiplying two negative numbers gives a positive result, so -40.5 times -1.8 equals +72.9. Therefore, the answer to your question is C. 72.9. This falls under the subject of Mathematics, specifically the topic of multiplication and handling positive and negative numbers.

Answers

Final answer:

The question is asking about the number of seats in a movie theater with 9 rows of 18 seats each and an additional section of handicapped accessible seats. The total number of seats can be found by multiplying the number of seats in each row (18) by the number of rows (9) and adding the number of handicapped accessible seats.

Explanation:

The subject of this question is Mathematics. The question is asking about the number of seats in a movie theater, given that there are 9 rows of 18 seats each and an additional section of handicapped accessible seats.

To find the total number of seats in the theater, you can multiply the number of seats in each row (18) by the number of rows (9) and then add the number of handicapped accessible seats.

So the total number of seats in the theater is 9 rows x 18 seats/row + additional handicapped accessible seats.
