what is the slop of the like that passes through the points (4,7) and (5,8)? write your answer in simplistic form

Paladinen [302]

Answer:

slope=1

Step-by-step explanation:

Formula for slope is m = y2 - y1 /x2 - x1

you will then use 7-8/4-5

Then -1/-1 which will simplify to 1

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 team is being formed that includes eight different people. There are eight different positions on the teams. How many differen

abruzzese [7]

Answer:

40320 different ways

Step-by-step explanation:

That problem is a permutation one

We have eight people to occupy one position in a team, without any constraint at all

Total number of events = P(8)

P (8) = 8!

P (8) = 8*7*6*5*4*3*2*1

P (8) = 40320 different ways
