A 20 foot ladder is leaned against a house and the base of the ladder is 4 feet from the house. How far up does the ladder reach?

Answers

Answer 1

Answer:

20.40 ft

Step-by-step explanation:

a^2 + b^2 = c^2 (right triangle) (sides of the triangle are the house and the distance from the base of the ladder to the house. The hypotenuse is the ladder.

20^2 + 4^2 = c^2

400 + 16 = c^2

C = sqrt 416

C = 20.40 ft

Answer:

Slope = -2

Step-by-step explanation:

Given the two points, (-4, 10) and (0, 2), the error in the given problem is the incorrect substitution of values into the formula. It should have been formatted as follows:

Let (x₁, y₁) = (-4, 10)

(x₂, y₂) = (0, 2)

The formula for solving for the slope of the line is:

m = (y₂ - y₁)/(x₂ - x₁)

where m represents the slope of the line.

Substitute the given values into the formula to solve for the slope:

m = (y₂ - y₁)/(x₂ - x₁)

[tex]m = \frac{2 - 10}{0 - (-4)}[/tex]

[tex]m = \frac{-8}{0 + 4 }[/tex]

m = -8/4

m = -2

Therefore, the slope of the line is -2.

How you calculate this is this:

So, any two given sides much be greater than the other side.

7. The answer is no. 1 plus 5 is 6 right? 6 is less than 11, so it can never be a triangle.

8. The answer is yes. 3 plus 6 is greater than 7. 3 plus 7 is greater than 6. 6 plus 7 is greater than 3.

9. The answer is yes. 9 plus 11 is greater than 12. 9 plus 12 is greater than 11. 11 plus 12 is greater than 9.

Find the value of x and y.

Answers

Answer:

x=8

y=3

Step-by-step explanation:

the triangle on the right side is equilateral, therefore also equiangular, which means each angle is 60 degrees

that means that 4x-2 = 30; 4x = 32; x = 8

also means that 7y+9 = 180-(90+60); 7y+9 = 30; 7y = 21; y = 3

Find the slope
X: 1, 5, 9, 13
Y: 1, 17, 33, 49

Answers

Answer:

Step-by-step explanation:

Givens

Take any two points (9,33) and (5,17)

Use the slope formula to determine what the slope might be

m = (y2 - y1)/(x2 - x1)

y2 = 33

y1 = 17

x2 = 9

x1 = 5

Solution

m = (33 -17) / (9 - 5)

m = 16/4

m = 4

Extra

Use 5,17 to get the y intercept

x = 5

y = 17

y = 4x + b

x = 5

y = 17

Use the general equation for a line: y = 4x + b and solve for b

17 = 4*5 + b

17 = 20 + b

b = - 3

So the line equation is y = 4x - 3

I did this extra work because I did not believe that 1,1 could be a solution for this equation given the other numbers. Turns out I was wrong. y = 4x - 3 has all 4 points on the line.

Step-by-step explanation:

x = 10 → (1)

3x + 5y = 20 → (2)

Substitute x = 10 into (2)

3(10) + 5y = 20

30 + 5y = 20 ( subtract 30 from both sides )

5y = - 10 ( divide both sides by 5 )

y = - 2

solution is (10, - 2 )

And to be clear, I don't mean adding a single note to a song and then calling it a new song, or changing a single note's pitch so slightly that it's beyond human hearing and calling it a new song, but really, with the limited amount of notations on a piano, can you make new songs, something that doesn't exist and has a completely new feel to it? And do you think you can do this over and over again endless amounts of times and if I had written trillions upon trillions upon trillions of piano pieces, could I make each and every one of them unique and special as opposed to the others? Even if you were to make a calculation and presume that a 10-note melody had 85 quintillion combinations on a modern 88 key piano, and then another calculation that told you how many chord progressions were possible in that 10-note melody, and both the melody and chord progression combinations were so vastly gigantic in numbers that you couldn't type it out within any amount of years, is it still finite? IS there still only a limited amount of musical ideas where one day we will have made every possible unique song? This is something iv'e had an existential crisis about as a want to be musician.
