<span>25.7 years
The rule of 72 is a simple approximation on how long it will take to double your money. You simply divide 72 by the interest rate and you'll have your estimate on the number of years it will take. So
72 / 2.8 = 25.7 years.
To demonstrate that it's just an estimate, you can take the log of 2 and divide by the log of 1.028 to get the exact value. This far more complicated calculation gives the result of 25.1 years. And to be honest, the estimate of 25.7 years is more than close enough for such an quick and easy rule of thumb.</span>
Y = -4/5 + 7, the 7 is the slope intercept and the -4/5 is the slope
18) 36.36 rounded it is 36.4
22)53.71 rounded it it’s just 53.7
Let's say imput is i and that output is o.
The formula is 2 ^ i = o
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
Notice how the numbers match?
Hope this helped :)
Answer:
sin-32/40
cos-24/40
tan-32/24
Step-by-step explanation:
SOHCAHTOA
sin is opposite over the hypotenuse
cosine is adjacent over hypotenuse
tan is opposite over adjacent
plug in the numbers corresponding with angle B and you get your formulas
so sorry if my explanation was bad
