Answer: 7x(4+7)
Step-by-step explanation:
Answer:
23.4 years.
Step-by-step explanation:
7400 dollars is placed in an account with an annual interest rate of 7%.
Now, let us assume that the interest is compounded annually and it will take x years for account value to reach 36000 dollars.
Hence, from the formula of compound interest, we can write that
⇒
Taking ln both sides we get,
x ln (1.07) = ln (4.865)
⇒ x = 23.4 years.
Answer:
4y+q(3-5q^2)
Step-by-step explanation:
common taking from 3q-5q^3
Use the Pythagorean theorem (a^2 + b^2 = c^2)
7^2 + 24^2 = x^2
x^2 = 625
x = 25
