A sum of money is invested at 12% compounded quarterly. About how long will it take for the amount of money to double?
Compound interest formula: V(t)-P
- P(1+5)**
t = years since initial deposit
n = number of times compounded per year
rannual interest rate (as a decimal)
p = initial (principal) investment
V(t) = value of investment after t years

i dont get the question

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
