Answer:

(x+16)^2=20^2+x^2

Step-by-step explanation:

Given there was no bending of the tree, the Pitagorean Theory would help finding the value of the trees hight.

x^2+32x+16^2=400+x^2

32x=(20-16)×(20+16)

x=144/32

x=4m and 50cm

If the interest rate is 7%, how many years will it take for your bank balance to double from $1,000 to $2,000?Enter the followin
svlad2 [7]

Answer:

It will take 14.29 years for your bank balance to double from $1,000 to $2,000.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

E = P*I*t

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

T = E + P.

If the interest rate is 7%, how many years will it take for your bank balance to double from $1,000 to $2,000?

We have that P = 1000, I = 0.07

We want to find t when E = 1000, so T = P + E = 2000.

E = P*I*t

1000 = 1000*0.07*t

t = \frac{1}{0.07}

t = 14.29

It will take 14.29 years for your bank balance to double from $1,000 to $2,000.
