Answer:

Part A : y²(x + 2)(x + 4)

Part B: (x + 4) (x + 4)

Part C: (x + 4) (x - 4)

Step-by-step explanation:

Part A: Factor x²y²+ 6xy²+ 8y²

x²y²+ 6xy²+ 8y²

y² is very common across the quadratic equation , hence

= y² (x² + 6x + 8)

= (y²) (x² + 6x + 8)

= (y²) (x² + 2x +4x + 8)

= (y²) (x² + 2x)+(4x + 8)

= (y²) (x(x + 2)+ 4(x + 2))

= y²(x+2)(x+4)

Part B: Factor x² + 8x + 16

x² + 8x + 16

= x² + 4x + 4x + 16

= (x² + 4x) + (4x + 16)

= x( x + 4) + 4(x + 4)

= (x + 4) (x + 4)

Part C: Factor x² − 16

= x² − 16

= x² + 0x − 16

= x² + 4x - 4x - 16

= (x² + 4x) - (4x - 16)

= x (x + 4) - 4(x + 4)

= (x + 4) (x - 4)

Answer:

D: 64 x^27 y^125

Step-by-step explanation:

You can use either a calc or your knowledge of cube roots. I will be using knowledge.

You can automatically rule out a and b as if you take the cube root of 12, no whole number comes out. You are left with c and d. Option D is correct because the cube root of 64 is a whole number (4), the cube root of 27 is a whole number (3), and the cube root of 125 is also a whole number(5).

Answer:

[tex]S.D = 15.98[/tex]

Step-by-step explanation:

Given: 76,45,64,80,92

Required: Determine the standard deviation

We start by calculating the mean

[tex]Mean = \frac {\sum x}{n}[/tex]

Where x-> 76,45,64,80,92 and n = 5

[tex]Mean = \frac {76+45+64+80+92}{5}[/tex]

[tex]Mean = \frac{357}{5}[/tex]

[tex]Mean = 71.4[/tex]

Subtract Mean (71.4) from each of the given data

[tex]76 - 71.4 = 4.6\\45 - 71.4 = -26.5\\64 - 71.4 = -7.4\\80 - 71.4 = 8.6\\92 - 71.4 = 20.6[/tex]

Determine the absolute value of the above result

[tex]|4.6| = 4.6\\|-26.5| = 26.5\\|-7.4| = 7.4\\|8.6| = 8.6\\|20.6| = 20.6[/tex]

Square Individual Result

[tex]4.6^2 = 21.16 \\26.5^2 = 702.25\\7.4^2 = 54.76\\8.6^2 = 73.96\\20.6^2 = 424.36[/tex]

Calculate the mean of the above result to give the variance

[tex]Mean = \frac {\sum x}{n}[/tex]

[tex]Mean = \frac{21.16 + 702.25 + 54.76 + 73.96 + 424.36}{5}\\Mean = \frac{1276.49}{5}\\Mean = 255.298[/tex]

Hence, Variance = 255.298

Standard Deviation is calculated by [tex]\sqrt{Var}[/tex]

[tex]SD = \sqrt{255.298}[/tex]

[tex]S.D = 15.9780474402[/tex]

[tex]S.D = 15.98 (Approximated)[/tex]

Answer:

Step-by-step explanation:

The graph represents the piecewise function:

f(x)=x^2 if x<2(if x is less than 2)  (the parabola was not transformed by any means and represents the parent function y=x^2)

f(x)=5 if 2≥x<4 (if x is greater than or equal to 2, but less than 4)(this is a horizontal line on y=5)

Answer:

THAT GUY SAID IT RIGHTD=

Step-by-step explanation:

Answer: x = 17.2

Step-by-step explanation:

So we can combine 8.7x and 1.9x as they are considered like terms.

So basically since they have the same base of x we can disregard the x when subtracting.

So its more like 8.7-1.9 which = 6.8

Now add the x back

So it is 6.8x = 116.96

Now we need to isolate the variable.

To do this we need to divide the 6.8 on both sides.

So x = 116.96/6.8

x = 17.2

Step-by-step explanation: Our first task in this problem is to setup variables representing length and width and we do that by using the second sentence.

The length is twice the width

So if we call our width x, that means that our length is 2 times x or 2x

Width of the rectangle ⇒ x

Length of the rectangle ⇒ 2x

Before moving on, go ahead and draw a picture of your

rectangle so that you can visualize what's going on.

I have done this for you below.

We label our widths x and our lengths 2x.

Now we can use the first sentence to setup our equation.

The perimeter of a rectangle is the distance

around the outside of the figure.

So if our perimeter is 60, that means that x + x + 2x + 2x = 60.

Simplifying by combining like terms, we get 6x = 60.

Now dividing both sides by 6, we find that x = 10.

Since x represents width, our width is 10.

Our length therefore with be 2(10) or 20.

So our width is 10 and our length is 20.

Answer:

c ≅ 35.4 cm.

Step-by-step explanation:

To find the length of the Hypotenuse of a triangle, the formula  a² + b² = c² will need to be used. Therefore:

26² + 24² = c² (c is the hypotenuse)

1252 = c²

√1252 = c

c ≈35.38

Round to tenths place:

c ≅ 35.4 cm. This is the Hypotenuse of the triangle.

Answer:

4.) x=-3 and y=4

Step-by-step explanation:

[x+4] + [-9x] = [28]

First plug in x into the equation

[-3+4] + [-9(-3)] = [28]

[1] + [27] = [28]

1+27=28 (True)

Next, plug in y into the equation

[y^2+1] + [-17] = [0]

[(4)(4)+1] + [-17] = [0]

[16+1] + [-17] = [0]

[17] + [-17] =[0]

17 + -17=0 (True)

Answer:

[tex]y=-4\,x-4[/tex]   which agrees with answer "A" in the list of possible options

Step-by-step explanation:

From the fact that there is a steady rate of increase in the x and in the respective y values (notice that x increases in steps of 1 unit, and at the same time y values increase in steps of "-4" units) the data belongs to the equation of a line.

We can determine that equation using just two pairs of points, like for example (-1, 0) and (0, -4).

We first find the slope using the slope formula for the segment that joints any two points on the plane:

[tex]slope=\frac{y_2-y_1}{x_2-x_1} \\slope=\frac{-4-0}{0-(-1)}\\slope = -4[/tex]

we now write the slope-intercept general form of a line with slope "-4", and solve for the intercept by using the point (0,-4) which should be in the line:

[tex]y=m\.x+b\\y=-4\,x+b\\-4=-4\,(0)+b\\b=-4[/tex]

Therefore the equation for this points is:

[tex]y=-4\,x-4[/tex]

Answer:

x= 50°

Hope it helps!

Step-by-step explanation:

The sum of the exterior angles of a polygon is always 360°

So, x+40+x+20+2x+2x = 360

6x + 60= 360

6x = 360-60 = 300

6x= 300

x= 300/6

Answer:

Number of child tickets = 9

Number of adult tickets = 36

Number of senior tickets = 27

Step-by-step explanation:

Given:

The ratio of adult tickets to child tickets = 4:1

Ratio of adult  tickets to senior tickets = 4:3

Number of total tickets = 72

Find:

The number of each ticket.

Computation:

Ratio between Adult to senior to child = 4:3:1

So,

Number of child tickets = [1 / (4+3+1)]Total tickets

Number of child tickets = [1 / (8)]72

Number of child tickets = 9

Number of adult tickets = [4 / (4+3+1)]Total tickets

Number of adult tickets = 36

Number of senior tickets = [3 / (4+3+1)]Total tickets

Number of senior tickets = 27

Hope this helps!

Answer:

the answer should be 7.875 I think?Hope this helps.

Step-by-step explanation:

24 is 2.5 standard deviations away from the mean.

Now it given that,

mean = 18

standard deviation = 4

value = 24

Let x be the standard deviation away from the mean.

Since we know that,

Mean + Standard deviation * x = Value

Therefore putting the value we get,

18 +  4x = 24

Subtracting 18 both the side,

or, 4x = 24 -18

or, 4x = 6

Dividing by 4 both the side we get,

or, x = 6/4

or, x = 2.25

Hence,24 is 2.5 standard deviations away from the mean.
