A ladder 25 feet long is leaning against a wall the bottom of the latter is 4 feet from the base of the wall how far up is the i
ICE Princess25 [194]

Answer:

The answer to your question is 24.7 ft

Step-by-step explanation:

Data

length of the ladder = 25 ft

distance from the ladder to the ladder = 4 ft

distance from the floor to the ladder = ?

Process

1.- Use the Pythagorean theorem to solve this problem

           c² = a² + b²

- solve for b

            b² = c² - a²

-Substitution

            b² = (25)² - (4)²

-Simplification

            b² = 625 - 16

            b² = 609

-Result

            b = 24.67 ft ≈ 24.7 ft

-Conclusion

The ladder is 24.7 ft from the floor.

Write an equation with the two points: (5,-2) and (3,4)
eimsori [14]

Answer:

y=-3x-17

Step-by-step explanation:

To find out the m(slope) of the equation use the formula:

\frac{y_2-y_1}{x_2-x_1}.

Substitute the values:

\frac{4--2}{3-5}

Combine the values:

\frac{6}{-2}

Find the value of the fraction:

-3

M is -3.

The equation so far is y=-3x+b

To find the y intercept, substitute one pair of coordinates into the equation and solve for b:

y=-3x+b\\-2=3*5+b\\-2=15+b\\-17=b.

We see that b =-17 so the full equation would be:

y=-3x-17.
