Explain and Show work so I can understand

length of hypotenuse = 10 ft.

Step-by-step explanation:

by pythagorus theorem,

( where, h = hypotenuse, b = base , h = height )

so,

=》

=》

=》

=》

=》

hence, hypotenuse = the 10 feet.

i hope it helped.....

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
