name a linear expressions that have (x+2) as a factor​

We are Given:_______________________________________________

ΔABC right angled at B

BC = 8

AC = 20

Part A:_____________________________________________________

Finding the length of AB

From the Pythagoras theorem, we know that:

AC² = BC² + AB²

replacing the given values

(20)² = (8)² + AB²

400 = 64 + AB²

AB² = 336                  [subtracting 64 from both sides]

AB = 18.3                   [taking the square root of both sides]

Part B:_____________________________________________________

Finding Sin(A)

we know that Sin(θ) = Opposite / Hypotenuse

The side opposite to ∠A is BC and The hypotenuse is AC

So, Sin(A) = BC / AC

Sin(A) = 8/20                      [plugging the values]

Sin(A) = 2/5

Part C:_____________________________________________________

Finding Cos(A)

We know that Cos(θ) = Adjacent / Hypotenuse

The Side adjacent to ∠A is AB and the hypotenuse is AC

So, Cos(A) = AB / AC

Cos(A) = 18.3/20                    [plugging the values]

Cos(A) = 183 / 200

Part D:_____________________________________________________

Finding Tan(A)

We know that Tan(θ) = Opposite / Adjacent

Since BC is opposite and AB is adjacent to ∠A

Tan(A) = BC / AB

Tan(A) = 8 / 18.3                  [plugging the values]

Tan(A) = 80 / 183

Answer:

by using Pythagoras law

ac²=ab²+bc²

20²=ab²+8²

ab²=20²-8²

AB=√336=18.33

Step-by-step explanation:

sin a=p/h=8/20=2/5

cos a =b/h=18.33/20

tana =p/b=8/18.33

Answer:

d. (9, 0)

Step-by-step explanation:

(x, y) so...

Where the line crosses the x-plane, x = 9

Since this is the x-intercept y will always equal zero

Therfore x-int = (9, 0)

Answer: 4.7x + 7.9

Step-by-step explanation:

Answer:

[tex]m(x, y)=(\frac{7}{2} , -\frac{5}{2} )[/tex]

Step-by-step explanation:

Midpoint of line segment is calculated as

[tex]m(x, y)=(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} )[/tex]  -----------(1)

Here

[tex](x_1, y_1) = (12,2) \ \ and \ \ (x_2, y_2) = (-5, -7)[/tex]

Substituting values in equation (1)

[tex]m(x, y)=(\frac{12-5}{2} , \frac{2-7}{2} )[/tex]

[tex]m(x, y)=(\frac{7}{2} , -\frac{5}{2} )[/tex]

Answer:

X = 56 degrees

Step-by-step explanation:

Angles D and F are equivalent. Because the three angles must add up to 180 degrees, you must add 112 to 68 in order to reach 180. Then you must divide this in half, getting 56 degrees as your answer.

180 - 68 = 112

112/2 = 56

X=56

Answer:

$72

Step-by-step explanation:

$768/265 = $3

$3 x 24 = $72

Answer:

$72

Step-by-step explanation:

768/256 = how much each hot dog was sold for

768/256 = 3

Each hot dog was sold for $3.

24*3 = $72

Therefore, the cost of 24 hot dogs is $72.

Given:

The expression is

[tex]\dfrac{\sqrt[3]{9}}{\sqrt[3]{4}}[/tex]

To find:

The simplified form of given expression.

Solution:

We have,

[tex]\dfrac{\sqrt[3]{9}}{\sqrt[3]{4}}[/tex]

It can be written as

[tex]\dfrac{\sqrt[3]{9}}{\sqrt[3]{4}}=\sqrt[3]{\dfrac{9}{4}}[/tex]                    [tex]\left[\because \dfrac{\sqrt[a]{x}}{\sqrt[a]{y}}=\sqrt[a]{\dfrac{x}{y}}\right][/tex]

Therefore, the simplified form of given expression is [tex]\sqrt[3]{\dfrac{9}{4}}[/tex].

Note: We can further simplify this expression but be need use exponential properties.  

Answer:

8x + 12

Step-by-step explanation:

1.) 4(2x + 3)

2.) 8x + 12

You just distribute it out. When you have 8x + 12 the only other thing you could do is factor it to get back to 4(2x + 3)! Hope this helps!

Answer:

8x + 12

Step-by-step explanation:

4 × 2x = 8x

4×3 = 12

8x +12

Answer:

m = 12.728 or 18/root (2)/2, n = 9

Step-by-step explanation:

To find m, we can use sin(45) and cos(45).

Since sin(45) = root (2)/2  and this equals 9/m.

We set the equation root (2)/2  = 9/m and solve for m.

9 divided by root (2)/2 would give us 18/root (2), or 12.728.

m is 12.728.

Same process for n but we are using cosine this time.

cos(45) = root (2)/2 and this equals n/12.728.

Solving for n would give us root (2)/2 times 12.728.

This gives us that n is 9.

Answer: I think that the answer is all of the above.

I am not 100% sure if that is completely correct so just pick some answers and see if they are correct.

Step-by-step explanation:

Step-by-step explanation:

Given Function

f(x) = 2.5x + 150

f^-1(x) = ?

Let y = f(x)

y = 2.5x + 150

Interchanging the role of x and y we get,

x = 2.5y + 150

x - 150 = 2.5y

y = (x - 150) / 2.5

So therefore

f^ -1(x) = (x - 150) / 2.5

Hope it will help :)

Step-by-step explanation:

Answer:

y = (1/3)x

Step-by-step explanation:

1) Use the slope formula: (y2-y1)/(x2-x1) and then substitute both points into the formula. That should give you (2-0)/(6-0) = 2/6 = 1/3.

1/3 would then be your slope

2) Since the y intercept is (0,0), the y-intercept isn't needed in the slope intercept equation

So that would give you y = (1/3)x
