Answer:

we are looking for F

but in the question it stated that f(n) and at the end it also stated that f(1) so n=1

Step-by-step explanation:

we are using BODMAS

f(n-1)+1

f(1-1)+1=0+1

f=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

<u>First situation</u>

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

<u>Find the length of the ladder</u>

Applying the Pythagorean Theorem

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

Step 2

<u>Second situation</u>

when the ladder will be lying flat on the ground

<u>Find the length of the ladder</u>

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

<u>the answer is</u>

the length of the ladder is 12\ ft

PLEASE HELP THIS IS MY LAST QUSTION OF THE DAY!!! :)<br> thanks in advanced
notsponge [240]

So using standard form you convert the equation to 5x - 2y = -10 then use slope m of a line of the form Ax + By = C equals negative a over b. It would be a = 5 b = -2 m = -5/-2 m = 5/2. Have a good day the answer is 5/2
