Answer:

  (c)  x² -64

Step-by-step explanation:

The factoring of the difference of squares is one of the special forms we use in the study of polynomials. It tells you ...

  a² -b² = (a +b)(a -b)

__

You have a factor (x +8), so a=x, b=8, and the "expanded" form is ...

  a² -b² = x² -8² = x² -64

Answer:

x^2-64

Step-by-step explanation:

just did the test

Answer:

62%

Step-by-step explanation:

10 000 ÷ 100 = 100

620 ÷ 100

= 62%

Step-by-step explanation:

For this problem, you'll need two formulas:

Slope: y1 - y2/x1 - x2

Point Slope: y - y1 = m(x - x1)

First thing you need to use is the slope formula.

Plugging in your coordinates gives you:

[tex]\frac{-2-3}{4-2}[/tex] = [tex]\frac{-5}{-2}[/tex]

You can simplify this by getting rid of the negatives since two negatives make a positive.

Now to use the point slope formula.

For this formula, the slope we just found, [tex]\frac{5}{2}[/tex], replaces the m, and for the x1 and y1, you use one of the original points(either (4,-2) or (2,3)).

I'll be using the point (2,3). Now plug everything in:

[tex]y-3=\frac{5}{2} (x-2)[/tex]

First thing you should do is distribute the [tex]\frac{5}{2}[/tex]:

[tex]y-3=\frac{5}{2} x-5[/tex]

Next thing to do is get the y by itself by adding 3 to both sides, which gives you your answer of:

[tex]y=\frac{5}{2} x-2[/tex]

Hope this was helpful, good luck :)

Answer:

Step-by-step explanation:

25% = 1/4 of 100

100 represents 200 people here, that means that if 25 = 1/4 to 100, then it is 1/8 to 200. 25x8=200

If 25% = 50, since 50x4=200 and 1/4 = 25% of 100%.

50... ok......

50 = 25%

Now, because there are 5 parts in 25, let's divide 5 by 50, that is 10. That means that 5 = 10 in that 50. 5% = 10 people

So, if 25-15=10

and then 5% = 10 people

5%+5%=10

10+10=20

That means, that 20 people more liked the movie than disliked it.

Step-by-step explanation:

Volume of cone: (1/3)π(9^2)(40)=1,080π

Volume of cylinder: π(3^2)(21)=189π

1,080π - 189π = 891π = 2799.2 square cm

Answer:

Reflection over the y-axis.

Step-by-step explanation:

All the x values will change sign so its over the yaxis

Answer:

a. The graph will be reflected over the y-axis

Step-by-step explanation:

When a function is reflected over the y-axis, the x-coordinates are divded by -1, and then the new points will become reflections of the y-axis. Because x was changed to -x in this problem, we know that the graph was relfected across the y-axis.

Answer:

A, E, B, D, C

Step-by-step explanation:

1) 6 is A

2) √83 = 9.11, so it is E

3) √40 = 6.3, so it is B

4) √64 = 8, so it is D

5) 7.5 is C

Answer:

15.4

Step-by-step explanation:

[tex]\frac{u}{4}[/tex] = tan51.3° ⇒ u = 4tan51.3° ≈ 5

[tex]\frac{4}{v}[/tex] = cos51.3° ⇒ v = [tex]\frac{4}{cos51.3}[/tex] ≈ 6.4

P ≈ 4 + 5 + 6.4 = 15.4

The perimeter of the triangle is 18.56.

The perimeter of the triangle is addition of all three sides.

Given:

The sides of angle is 4, u and v.

The angle of triangle is 51.3 degree.

For finding the value of u and v.

               [tex]tan\theta=\frac{opposite}{Adjacent}[/tex]

tan 51.3 = u/4

1.682 =u/4

u = 6.72

             [tex]cos\theta=\frac{adjacent}{hypotenuse}[/tex]

cos 51.3 = 4/v

0.51 = 4/v

v = 7.84

Perimeter = u + v + 4

                 = 6.72 + 7.84 + 4

                 = 18.56.

Therefore, the perimeter of this triangle is 18.56.

The three (3) products that resulted in a difference of squares are:

In Mathematics, the standard form for a difference of two (2) squares is given by a² - b² = (a + b)(a - b).

(3 + xz)(-3 + xz) = (3 + xz)(xz -3)

(3 + xz)(xz -3) = 3xz - 9 + x²z² - 3xz.

(3 + xz)(xz -3) = x²z² - 9

Therefore, x²z² - 9 ≡ a² - b²

(y² - xy)(y² + xy) = y⁴ + xy³ - xy³ - x²y²

(y² - xy)(y² + xy) = y⁴ - x²y²

Therefore, y⁴ - x²y² ≡ a² - b².

(64y² + x²)(-x² + 64y²) = (64y² + x²)(64y² - x²)

(64y² + x²)(-x² + 64y²) = 4096y⁴- 64y²x² + 64y²x² - x⁴

(64y² + x²)(-x² + 64y²) = 4096y⁴ - x⁴

Therefore, 4096y⁴ - x⁴ ≡ a² - b².

Answer:

B.  F(x) = (x+1)/(x-1)(x+2)

Step-by-step explanation:

See attached graph.  Note how the two vertical lines at x = -2 and 1 match plot B

The following graph is of the rational function [tex]F(x) = \frac{x+1}{(x-1)(x+2)} \\[/tex]

What are asymptotes?

An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance.

The rational function does not exist at x = 1 and x = -2 ( as observed in graph). Thus, the denominator of the function consist (x-1) and (x+2). It is only in option B, thus it is correct.

Answer:

9 first class tickets

4 coach tickets

Step-by-step explanation:

Let x = number of first class tickets bought

Let y = number of coach tickets bought

Given:

⇒ x + y = 13

Given:

⇒ 1180x + 240y = 11580

Rewrite first equation to make y the subject:

⇒ y = 13 - x

Substitute this into the second equation and solve for x:

⇒ 240(13 - x) + 1180x = 11580

⇒ 3120 - 240x + 1180x = 11580

⇒ 940x = 8460

⇒ x = 9

Therefore, 9 first class tickets were bought.

To find the number of coach tickets bought, simply substitute the found value of x into equation 1 and solve for y:

⇒ 9 + y = 13

⇒ y = 4

Therefore, 4 coach tickets were bought.
