Answer:

The equation 2x + 3 = x + x + 3 is an example of an equation that has an infinite number of solutions. Let's see what happens when we solve it. We first combine our like terms.

Step-by-step explanation:

pply the Distributive Property. 2. Combine like terms. 3. Add/subtract on both sides. 4. Multiply/divide on both sides. Note: You might not need to do all of these steps! Special Cases – 1. Infinitely many solutions - when solving your equation, you get results like. 0=0, 7=7 ... 3) 5(2x - 7) = 7x + 3x + 7. 4) 4x +2x - 2 = 6x -- 3 + 1

Answer:

1)

Minimum is a 4th Degree

2)

Positive; Even

3)

[tex]x=-4, -1\text{ Odd Multiplicity}\\x=3\text{ Even Multiplicity}[/tex]

Step-by-step explanation:

Part 1)

The minimum degree of our function will be 4.

Looking at the graph, we know that the graph crosses the x-axis at -4 and -1. Since it crosses through the x-axis at these two points, these two factors must have an odd multiplicity.

So, it can be anything 1, 3, 5, 7, etc.

However, we will choose the lowest one, 1.

Next, we know that the graph bounces off at 3.

So, it must have an even multiplicity. In other words, 2, 4, 6, 8, etc.

We choose the lowest one, 2.

Therefore, the minimum degree of our function will be 1+1+2 or 4.

Part 2)

The degree of our polynomial is (and will always be) even. Therefore, both ends of the graph will go in the same direction.

Recall the simplest even polynomial, the parent quadratic function. When the leading coefficient is positive, both of the ends go straight up.

This applies to all polynomials with even degrees.

Therefore, since the arms of the graph is going straight up towards positive infinity, the leading coefficient of our graph must be positive.

Part 3)

This is similar to Part 1.

We can see that the graph touches the x-axis at -4, -3, and 1. So, the zeros of the function is: [tex]x=-4, -1, 3[/tex]

We know that it passes through [tex]x=-4 \text{ and } x=-1[/tex] . So, these two factors must have an odd multiplicity.

However, since the graph bounces off [tex]x=3[/tex], this factor must have an even multiplicity.

And we're done!

Step-by-step explanation:

Given the data :

Response time this year :

3.0, 12.0, 7.0, 4.0, 4.0, 6.0, 3.0, 9.0, 11.0, 15.0

Response time last year :

8.0, 7.0, 8.0, 6.0, 6.0, 9.0, 7.0, 9.0, 8.0, 6.0

Let's calculate the mean and standard deviation of each data sample :

Mean(m) = Σ(X) / n

n = sample size = 4

This year:

ΣX = 74 ; n = 10

Mean = 74 /10 = 7. 4

Standard deviation(s) = √(Σ(x - m)²/n - 1)

s = 4.195

Using a calculator to save computation time :Standard deviation = 4.195

LAST YEAR :

ΣX = 74 ; n = 10

Mean = 74 /10 = 7. 4

Standard deviation(s) = √(Σ(x - m)²/n - 1)

Using a calculator to save computation time :Standard deviation = 1.17

a. Does he see a performance variation by the mean?

From the mean value obtained for the two years, both are the same, hence, the value does not signify a variation in performance.

b. Does he see a performance variation by the standard deviation? If he does, is it performance improvement or deterioration from the last year? Why?

Yes, the value of standard deviation are different with the current year having a value of 4.195 and the previous year, a value of 1.17

The variation shows there is a deterioration on this year's performance from last year due to the larger value of standard deviation obtained ; 4.195 > 1.17

Answer:

the correct answer is that Screen B is wider, because 5 and one-third is greater than 5.3.

Step-by-step explanation:

E D G E N U I T Y  2020

The Screen B is wider, because 5 and one-third is greater than 5.3.

A decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point. The dot in a decimal number is called a decimal point. The digits following the decimal point show a value smaller than one.

According to the question

George is comparing two different phones.

Phone A : screen  has a width of 5.3 cm

Phone B : The width of the screen is 5 and one-third cm.  

i.e

The width of the screen of phone B = [tex]5\frac{1}{3}[/tex] cm

                                                           = [tex]\frac{16}{3}[/tex] cm

Converting it into decimal to compare

                                                           = 5.333 cm

Therefore ,

5.333 cm > 5.3 cm  

i.e Phone B screen > Phone A screen

Hence, Screen B is wider, because 5 and one-third is greater than 5.3.

Given:

The given equation is

[tex]y-3=(2-x)^2[/tex]

To find:

The vertex, focus, and directrix.

Solution:

The equation of a parabola is

[tex]y-k=a(x-h)^2[/tex]     ...(i)

where, (h,k) is vertex, [tex]\left(h,k+\dfrac{1}{4a}\right)[/tex] and directrix is [tex]y=k-\dfrac{1}{4a}[/tex]

We have,

[tex]y-3=(2-x)^2[/tex]

It can be written as

[tex]y-3=(-(x-2))^2[/tex]

[tex]y-3=(x-2)^2[/tex]    ...(ii)

On comparing (i) and (ii), we get

[tex]h=2,k=3,a=1[/tex]

Vertex of the parabola is (2,3).

[tex]Focus=\left(2,3+\dfrac{1}{4(1)}\right)[/tex]

[tex]Focus=\left(2,3+\dfrac{1}{4}\right)[/tex]

[tex]Focus=\left(2,\dfrac{13}{4}\right)[/tex]

Therefore, the focus of the parabola is [tex]\left(2,\dfrac{13}{4}\right)[/tex].

Directrix of the parabola is

[tex]y=3-\dfrac{1}{4(1)}[/tex]

[tex]y=3-\dfrac{1}{4}[/tex]

[tex]y=\dfrac{11}{4}[/tex]

Therefore, the directrix of the parabola is [tex]y=\dfrac{11}{4}[/tex].

Answer:

correct answer: a.

Step-by-step explanation:

y = tan2x graph should have right side headed up, because it's positive.

however, the graph's frequency should be changed.

Since the normal period of y = tan x graph is pi/|b|,

the period for this graph should be pi/2.

We can see that graph (a) is meeting all the needs.
