A fireman learned a 36 foot ladder against a building.If he placed the ladder 7 feet from the base of the building,what angle is formed between the ladder and the ground?

Answers

Answer 1

Answer:
The angle between the ladder and ground is 78.78°

Explanation:
It is given that the length of the ladder is 36 foot and the distance between the base and the ladder is 7 feet.

Here we can see that the hypotenuse is 36 foot and the base is 7 feet. To find the angle between the ladder and the ground we take the cos inverse of 7/36.

Let the angle between the ladder and the ground is ‘x’.

20y-10x=5 in slope intercept form can you explain the steps

Answers

Given:

The equation is

[tex]20y-10x+5[/tex]

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

[tex]y=mx+b[/tex]

Where, m is slope and b is the y-intercept.

We have,

[tex]20y-10x=5[/tex]

We need to isolate y. Add 10x on both sides.

[tex]20y-10x+10x=5+10x[/tex]

[tex]20y=5+10x[/tex]

Divide both sides by 20.

[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]

[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]

[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]

[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]

Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].

Which polynomial function could be represented by the graph below?

On a coordinate plane, a parabola opens up. It goes through (2, 0), has a vertex at (3, negative 3), and goes through (4, 0).

Answers

Answer:

f(x) = 3(x - 3)^2 - 3

Step-by-step explanation:

Let the base function be

f(x) = ax^2

It has the vertex at (3, -3), so it is translated 3 units right and 3 units down:

f(x) = a(x - 3)^2 - 3

It has zero's at (2, 0) and (4, 0)

Substitute and solve for a:

a(x - 3)^2 - 3 = 0a(2 - 3)^2 = 3a = 3

a(4 - 3)^2 - 3 = 0a = 3

So the function is:

f(x) = 3(x - 3)^2 - 3

See the attached

f(x) = 3x2 – 18x + 24

3(3x - 9)

x(9x - 3)

3(3x - 7)

Answers

Answer:

1) 9(x - 3) = 9x - 27. So, 1) applies.

2) 3(3x - 9) = 9x - 27. So, 2) applies.

3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.

4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.

5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.

Step-by-step explanation:

1) 9(x - 3) = 9x - 27. So, 1) applies.

2) 3(3x - 9) = 9x - 27. So, 2) applies.

3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.

5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.

The expressions that are equivalent to 9x - 27 are:

9(x - 3)

3(3x - 9)

To determine which expressions are equivalent to 9x - 27, let's simplify each of the given options:

9(x - 3):

Expanding the expression, we get 9x - 27.

This expression is equivalent to 9x - 27.

3(3x - 9):

Expanding the expression, we get 9x - 27.

This expression is equivalent to 9x - 27.

x(9x - 3):

Expanding the expression, we get 9x² - 3x.

This expression is NOT equivalent to 9x - 27.

3(3x - 7):

Expanding the expression, we get 9x - 21.

This expression is NOT equivalent to 9x - 27.

3(x - 9):

Expanding the expression, we get 3x - 27.

This expression is NOT equivalent to 9x - 27.

Therefore, the expressions that are equivalent to 9x - 27 are:

9(x - 3)

3(3x - 9)

So, the correct options are 1 and 2.

Step-by-step explanation:

Linear pairs of angles sum to 180.

Subtract 39 from both sides

3x = 141

Find the percent change by finding the difference between the amounts, then dividing it by the original amount

(4,100 - 2,500) / 2,500

1600 / 2500

= 0.64

So, the percent change is 64%

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y

Answers

Answer: x = 1 and y = -1

Step-by-step explanation:

Since both equations are equal to y, that means the equations are both equal to each other

5x - 6 = -4x + 3

Solve for x how you would traditionally do it with any other one-variable equation

9x = 9

x = 1

Plug the now known x value into either equation and you will get your y value.

5(1) - 6 = -1

-4(1) + 3 = -1
