A rule for nth term of -2 , -5/4 ,-1/2,1/4

miv72 [106K]

Answer:

Step-by-step explanation:

This is an arithmetic sequence

a1 = -2

Difference = 2nd term - first term

$=\frac{-5}{4}-[-2]\\\\=\frac{-5}{4}+2\\\\=\frac{-5}{4}+\frac{2*4}{1*4}\\\\=\frac{-5+8}{4}=\frac{3}{4}$

$a_{n}=a+(n-1)d\\\\=-2+(n-1)*(\frac{3}{4})\\\\=-2+\frac{3}{4}n-\frac{3}{4}\\\\=\frac{-2*4}{1*4}-\frac{3}{4}+\frac{3}{4}n\\\\=\frac{-8-3}{4}+\frac{3}{4}n\\\\=\frac{-11}{4}+\frac{3}{4}n$

A woman is trapped in a burning building, 60 feet above the ground. To rescue the woman, a fireman places the bottom of a large

AnnyKZ [126]

Height of building =60 feet (where woman is trapped)

distance of bottom of ladder from base of building = 40 feet

This makes a right angled triangle as shown in figure.

here hypotenuse =length of ladder

base = distance of bottom of ladder from base of building = 40 feet

perpendicular =Height of building =60 feet (where woman is trapped)

So here we can use Pythagoras theorem to find the length of ladder.

Hypotenuse² = base² + perpendicular²

height of ladder = √(60² +(40)² = √3600 +1600 = √5200

height of ladder = 72.1 feet
