How will you graph the function g(x) = (x – 4)+ 12 using the parent quadratic function, f (x) = x2?

Answer:

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Step-by-step explanation:

Given

Total length of one roll of ribbon = 9 feet

As the pieces have to be cut into inches, we will convert the measurement in feet to inches

As there are 12 inches in one feet, 9 feet will be equal to:

9*12 = 108 inches

Now first of all, we have to see how many 15 inches pieces can be cut from one role

So,

[tex]=\frac{Length\ of\ roll}{Length\ of\ piece}\\=\frac{108}{15}\\=7.2[/tex]

So the seamstress can cut 7 15-inch long pieces from a roll.

Now given that he has to cut from 5 rolls, the total number of 15-inch pieces will be:

[tex]= 5 * 7 =35[/tex]

Hence,

The greatest number of 15 inches pieces that can be cut from 5 rolls of length 9 feet is: 35

Answer:

The population mean (μ) = 26.

Step-by-step explanation:

a) Data and Calculations:

The population characteristics = 20 and 36

Total population of interest = 56 (20 + 36)

Number of groups in the population = 2

Therefore, the population mean (μ) = 56/2 = 28

b) Based on the parameters given in this example, the population mean equals the average of the group characteristic (attention span of individuals in minutes) or item of interest.  The population mean is calculated by adding the values of the group characteristic and then dividing the result by the number of values.

Answer:

x = 30

Step-by-step explanation:

Look at triangle LMN.

m<NLM + m<M + m<MNL = 180

90 + m<M + 45 = 180

m<M = 45

Theorem: The measure of an exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

<ONM is an exterior angle of triangle KMN.

The remote interior angles are <K and <M.

m<K + m<M = m<ONM

2x + 45 = 105

2x = 60

x = 30

Answer: x = 30

Answer:

The unemployment rate would be 5.5%.

Step-by-step explanation:

It is given that,

The Canadian labor force as of 2019 was 32.7 million.

There were 30.9 million employed

We need to find the unemployment rate.

Unemployed = labor force - employed

= 32.7 - 30.9

= 1.8 million

[tex]\text{unemployment rate}=\dfrac{\text{unemployed}}{\text{labor force}}\times 100\\\\=\dfrac{1.8}{32.7}\times 100\\\\=5.5\%[/tex]

So, the unemployment rate would be 5.5%.

Answer:

We conclude that the percent of decrease = 20%

Step-by-step explanation:

Given

Using the formula

Percent of decrease = ( amount of decrease / orignal amount × 100 ) %

                                   = ( 786 / 3930 × 100 ) %

                                    = ( 0.2 × 100 ) %

                                    = 20%

Therefore, we conclude that the percent of decrease = 20%

Answer:

A= –5x2 + 4x – 7y + 14 = 0

C= 9x2 – 12xy + 4y2 + 4x – y + 5 = 0

D= 12x + 6y – 5y2 + 14 = 0

Step-by-step explanation:

I finished the assignment from Edge2020

The equation which would produce a parabola from the provided options are equation first and forth,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

To of identify the type of conic section from an equation whether it is parabola, or not, let suppose the equation as,

[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]

If In this equation,

Either [tex]A=0[/tex] or [tex]B=0[/tex], but not both. Then it is the equation of parabola.

The first equation is,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

There is no square term of y. Thus, this is the equation of parabola.

The second equation is,

[tex]-x^2 + 6x + y^2 - 8 = 0[/tex]

This is not the equation of parabola, as there is two square terms of variable x and y.

The third equation is,

[tex]9x^2 - 12xy + 4y^2 + 4x - y + 5 = 0[/tex]

Similar to the second equation, here is also two square terms of different variable. Thus, it is not a equation of parabola.              

The fourth equation is,

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

This equation is the equation of parabola, as there is only a single square term.

The fifth equation is,

[tex]20x^2 + 10xy - y^2 + 3x - 6y + 5 = 0[/tex]

This is now the equation of parabola because of two square terms.

Hence, the equation which would produce a parabola from the provided options are equation first and forth,

[tex]-5x^2 + 4x - 7y + 14 = 0[/tex]

[tex]12x + 6y -5y^2 + 14 = 0[/tex]

Answer:

Step-by-step explanation:

If the wall is perpendicular, then that means that this is a right triangle. We can find out if it is by using Pythagorean's Theorem and filling in the values for the sides. If the statement is true, then the triangle is right and the wall is perpendicular to the base.

[tex]a^2+b^2=c^2[/tex] and filling in:

[tex]7^2+8^2=12^2[/tex] Let's find out if this is true:

[tex]49+64=144[/tex] Is this true?

113 = 144

Definitely not true. So this is not a right triangle and the wall is not perpendicular to the floor.

Given,

Total number of votes casted = 42,000

The winner received 3/5 of the votes.

To find,

How many votes did the winner not receive.

Solution,

Votes received by the winner is :

[tex]\dfrac{3}{5}\times 42000\\\\=25200[/tex]

Votes didn't received by the winner = Total votes - votes received

= 42,000 -25200

= 16800

Hence, 16800  votes is not received by the winner.

Answer:

The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

Step-by-step explanation:

Area of a Circle

A circle of radius r has an area calculated by the following formula:

[tex]A=\pi r^2[/tex]

The diameter of a circle is twice the radius, thus the radius is half the value of the diameter.

A given circle has a diameter of 5 inches.

The radius of this circle is r = 5/2 = 2.5 inches.

Thus, the area is calculated below:

[tex]A=\pi 2.5^2 = 6.25\pi[/tex]

The area of the circle is [tex]\mathbf{6.25\pi}[/tex]

Answer:

C

Step-by-step explanation:

If the parabola opens upward, it has a minimum.

If it opens downwards, it has a maximum.

Every quadratic function either has a maximum or minimum value is true, because the graph of a quadratic function is a parabola that either opens downwards or upwards.

A quadratic function is a polynomial function with one or more variables in which the highest exponent of the variable is two. Since the highest degree term in a quadratic function is of the second degree, therefore it is also called the polynomial of degree 2.

Three properties that are universal to all quadratic functions:

1) The graph of a quadratic function is always a parabola that either opens upward or downward (end behavior).

2) The domain of a quadratic function is all real numbers.

3) The vertex is the lowest point when the parabola opens upwards; while the vertex is the highest point when the parabola opens downwards.

According to the question

Every quadratic function either has a maximum or minimum value.

As per the properties of Quadratic Function

This statement is true as

i> the graph of a quadratic function is a parabola  

ii> The vertex is the lowest point when the parabola opens upwards or the vertex is the highest point when the parabola opens downwards.

Hence, Every quadratic function either has a maximum or minimum value is true, because the graph of a quadratic function is a parabola that either opens downwards or upwards.
