The answer is 53.85 x 1.54 = 77
Cot x = cos x / sin x
or Cot x = 1/ tan x
Given:
Cot x = 4
Tan x = 1/4
x = 14.03 degrees
Answer:
125in^2
Step-by-step explanation:
Surface area= Area of base+ 1/2ps
since it's a square the area of the base is 5 x 5 which equals 25
next we multiply the perimeter by s which is 10
it's a square so the perimeter is 5+5+5+5 = 25
so 25+1/2(250)
25+ 125
=125 in^2
Let's say the APR is 5%. That means you get 5% of your balance back every year. The $100 balance would get $5 back, the $500 balance would get $25 back, and the $1000 balance would get $50 back. Therefore, all of the balances would take the same amount of time to double, and it would take all of them 20 years.
$5*20 years=$100
$25*20 years=$500
$50*20 years=$1000
