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

Select all correct answers.

A.)
k(x)=3x^2

B.)
j(x)=2x^2

C.)
g(x)=−4x^2

D.)
h(x)=−2x^2

E.)
m(x)=4x^2

Answers

Answer 1
Steepness in quadratic functions refers to how wide or narrow the graph is.

Positive/negative doesn't affect steepness in this situation so A would be out because it is essentially the same as the problem.

You would have to use graph transformations. When a number is front of the whole equation like how 3 is in front of x^2, it stretches the graph VERTICALLY making the graph MORE STEEP.

So which graphs has the largest coefficient (disregarding the negative signs)

It says graphs (with an s) so it would be C and E.

hope this helps C:

How can sums and differences of cubes be identified for factoring?

Answers

The sum of cubes is given as:
a³ + b³ = (a + b)(a² - ab + b²)

Example for the sum of cubes:

64x³+y³ ⇒ This is the sum of cubes because each term; 64, x³, and y³ are cube numbers

By writing each term as an expression of cube numbers, we have:
(4x)³ + (y)³ ⇒ 64 is 4³
Use the factorization of the sum of cubes, we have:
(4x + y) ( (4x)²- 4xy + y²)
(4x + y) (16x² - 4xy + y²)

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

The difference of cubes can be factorized as:
(x³ - y³) = (x - y)(x² + xy + y²)

Example
(125x³ - 8y³) = (5x - 2y) ((5x)² + (5x)(2y) + (2y)²)
                     = (5x - 2y) (25x² + 10xy + 4y²)

How is angle a related to angle d?
A) vertical angles
B) alternate interior angles
C) alternate exterior angles
D) corresponding angles

Answers

Answer: Option 'A' is correct.

Step-by-step explanation:

since we have given a line AB and CD such that AB║CD,

And a transversal say 'l' cut the two parallel lines

And we know that when a transversal cuts two parallel lines we get linear pair and corresponding angles

But relation between angle 'a' and angle 'd' is vertically opposite angles.

So, Option 'A' is correct.

In order for the data in the table to represent a linear function with a rate of change of –8, what must be the value of m?

m = 2
m = 3
m = 19
m = 35

Answers

a rate of change of –8
so
27 - 8 = 19
19 - 8 = 11

answer

m = 19

Answer:

m= 19

Step-by-step explanation:

In a linear function the rate of change of y-variable respect x-variable must be constant. In mathematical terms:

Δy/Δx = constant

Given two points of the function: (x1, y1) and (x2, y2), Δy = (y2 -y1) and Δx = (x2 -x1).  So,

Δy/Δx = (11 -27)/(12-10) = -8

(m -27)/(11-10) = -8

(m -27) = -8*(11-10)

m = -8 + 27

m = 19

if the inequality has the same number on both sides for the answer is that ok?

Answers

If the problem was |6y+6| < 0, then you would be able to say 0 < 6y+6 < 0 (because of the template below)

Template:
if |x| < k, then -k < x < k

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

However, the inequality sign is not a "less than" sign. Instead its a "greater than" sign. 

So instead you should use this template

if |x| > k then x > k or x < -k

So if 
|6y+6| > 0
then
6y+6 > 0 or 6y+6 < 0

Solve each inequality for y
6y+6 > 0
6y+6-6 > 0-6 ... subtract 6 from both sides
6y > -6
6y/6 > -6/6 ... divide both sides by 6
y > -1

Do the same for the other inequality
6y+6 < 0
6y+6-6 < -6
6y < -6
6y/6 < -6/6
y < -1

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

So overall, the two solutions are y > -1 or y < -1

The keyword "or" is important. You can only choose one inequality or the other, but not both.

When is a protractor preferred to a ruler when finding a measurement

Answers

When measuring an angle.

A protractor is preferred over a ruler when measuring angles, especially in geometric shapes or when dealing with rotational aspects. While a ruler is great for measuring lengths and distances, it can't accurately measure angles.

For example, let's say you want to measure the angle between two lines on a piece of paper. A ruler can only give you an approximation by comparing lengths, but a protractor will give you an exact measurement of the angle in degrees.

To use a protractor, align the center hole of the protractor with the vertex of the angle. Then, align one side of the angle with the zero-degree mark on the protractor. Finally, read the number where the second side of the angle intersects the protractor scale. This gives you the precise measurement of the angle.

In conclusion, when dealing with angles, a protractor is the preferred tool for accurate measurements, providing exact angles in degrees.

Twelve less than negative nine times a number is equal to 8 minus 4 times the number find the number

Answers

Final answer:

The number that satisfies the original equation is -4.

Explanation:

A student's question involves finding a number that satisfies the equation: 'Twelve less than negative nine times a number is equal to 8 minus 4 times the number'.

To solve this, we set up the equation -9x - 12 = 8 - 4x.

Solving for 'x' involves simple algebraic steps.

First, add 9x to both sides to get the variable terms on one side:

-9x - 12 + 9x = 8 - 4x + 9x-12 = 8 + 5x

Next, subtract 8 from both sides to isolate the variable term:

-12 - 8 = 5x-20 = 5x

Finally, divide both sides by 5 to find 'x':

-20 / 5 = 5x / 5-4 = x

The number that satisfies the original equation is -4.

A dentist is making identical dental care bags for patients using 56 tubes of toothpaste, 112 packets of floss, and 85 toothbrushes. What is the greatest number of identical dental care bags the dentist can make with the least amount of items leftover. Describe the contents of each bag.

Answers

If we leftover 1 toothbrush, we will have:
56 tubes of toothpaste, 112 packets of floss and 84 toothbrushes.
The greatest common factor:
GCF ( 56, 112, 84 ) = 28
56 : 28 = 2, 112 : 28 = 4, 84 : 28 = 3
Answer:
The greatest number of identical dental care bags is 28.
In every bag will be 2 tubes of toothpaste, 4 packets of floss and 3 toothbrushes. One toothbrush will be leftover.
 
Greatest number of identical dental care bags is equal to the L.C.M. of 56, 112 & 85.

56 = 2 x 2 x 2 x 7
112 = 2 x 2 x 2 x 2 x 7
85 = 5 x 17

L.C.M. (56, 112, 85) = 2 x 2 x 2 x 2 x 5 x 7 x 17
= 560 x 17
= 9520

Therefore, 9520 is the correct answer.

Claire's cousin is now 3 times as old as Claire. in 10 years, her cousin will be twice as old as claire. how old is Claire now?

Answers

the answer will be 7
Final answer:

Claire is currently 10 years old.

Explanation:

Let's assume that Claire's age is x.

According to the given information, Claire's cousin is now 3 times as old as Claire. This can be represented as Cousin's age = 3x.

In 10 years, Cousin's age will be twice as old as Claire's age. So, we can write the equation:

(3x + 10) = 2(x + 10)

Simplifying the equation:

3x + 10 = 2x + 20

Subtracting 2x from both sides:

x + 10 = 20

Subtracting 10 from both sides:

x = 10

Therefore, Claire is currently 10 years old.

Among all rectangles that have a perimeter of 156, find the dimensions of the one whose area is largest. write your answers as fractions reduced to lowest terms.

Answers

P = 2L + 2W

We have a perimeter of 156, so we have

2L + 2W = 156

Let the length = x

2x + 2W = 156

The width is

2W = 156 - 2x

W = 78 - x

The area of a rectangle is A = LW

A = x(78 - x)

A = 78x - x^2

This is an inverted parabola, so there is a maximum value.

78x - x^2 = 0

x(78 - x) = 0

x = 0 or x = 78

The zeros of the parabola are at x = 0 and x = 78.
Since the parabola is symmetric over its vertical axis, the maximum values occurs at the x-value in the middle of 0 to 78, which is 39.

At x = 39, the area has a maximum value.

L = 39 & W = 39

It's a square with side measuring 39.

The dimensions of the one whose area is largest is 39 by 39

The formula for calculating the perimeter of a rectangle is expressed as:

P = 2(L + W)

L is the length of the rectangle

W is the width

Given that the perimeter is 156, hence;

2(L + W) = 156

2L + 2W = 156

L + W = 78

W = 78 - L

The area of the rectangle is expressed as:

A = LW

A = L(78-L)

A = 78L - L^2

To get the dimensions of the one whose area is largest, dA/dL = 0

dA/dL = 78 - 2L

0 = 78 - 2L

2L = 78

L = 78/2

L = 39

Recall that 2(L+W) = 156

2(39 + W) = 156

39 + W = 78

W = 78 - 39

W = 39

Hence the dimensions of the one whose area is largest is 39 by 39
