A ladder is leaning against a wall. The top of the ladder is 9 feet (ft) above the ground. If the bottom of the ladder is moved

Komok [63]

Step 1

First situation

when a ladder is leaning against a wall

Let

x-------> the distance of the bottom of the ladder from the wall

L-------> the length of the ladder

Find the length of the ladder

Applying the Pythagorean Theorem

$L^{2} =x^{2}+ 9^{2}$ ------> equation $1$

Step 2

Second situation

when the ladder will be lying flat on the ground

Find the length of the ladder

In this situation the length of the ladder is equal to

$L=x+3$

square both sides

$L^{2}=(x+3)^{2}$ ------> equation $2$

Step 3

equate equation $1$ and equation $2$

$x^{2}+ 9^{2}=(x+3)^{2}\\x^{2}+81=x^{2} +6x+9\\ 6x=81-9\\6x=72\\x=12\ ft$

therefore

the answer is

the length of the ladder is $12\ ft$

A scientist wants to research the potential spread of germs by contact. she knows that the number of possible handshakes within

Viefleur [7K]

Given that the number of possible handshakes within a group of n people is given by the equation:

 $N= \frac{1}{2} (n^2-n)$

Given that there are 105 people at a party, the number of possible handshakes is given by:

 $N= \frac{1}{2} (105^2-105) \\ \\ = \frac{1}{2} (11025-105)=10920$

Name at least two independent variables that could result in a change in a monthly electric bill

CaHeK987 [17]

Answer:

1. The amount of time you keep your porch light on.

2. The temperature you keep your air conditioner at.

Step-by-step explanation:

Porch Light Time Example:

The light does not turn on or off based on the bill, thus its independent, but the bill is effected by the amount of time the light is on thus dependent.

You keep your porch light on for 24 hours a day for 1 month, that month your electricity bill is $50.

Next month you keep your porch light on for 12 hours a day and your electricity bill is $40.

Air Conditioner Temp Example:

The thermostat temperature is not effected by the bill, thus its independent, but the bill is effected by the thermostat, thus dependent.

You set your thermostat to 70 degrees for 1 month, that month your electricity bill is $50.

Next month you set your thermostat to 75 degrees for 1 month, that month your electricity bill is $40.

erik [133]

Answer:

$\Huge \boxed{x=-2}$

Step-by-step explanation:

$-7x=14$

Dividing both sides by -7.

$\displaystyle \frac{-7x}{-7} =\frac{14}{-7}$

$x=-2$

There is only one solution that satisfies the equation.
