Answer:

  1.55%

Step-by-step explanation:

Fill in the values and solve for the rate using the future value formula.

  FV = P(1 +r/n)^(nt)

  4720 = 4300(1 +r/12)^(12·6)

  (4720/4300)^(1/72) = 1 +r/12

  r = 12(4720/4300)^(1/72) -1) ≈ 0.015542

The annual interest rate is about 1.55%.

Answer :

a = 1, b = -8, c = -5

Explanation

A standard form for the quadratic function is f(x) = ax2 + bx + c where the coefficients are a, b, and c.
The given quadratic function is f(p) = P2 - 8P - 5 When this function is compared to the standard form, with p replacing x, we obtain a = 1 because the leading term is 1*p2, b = -8 because the linear term is -8*p, c = -5 because the constant term is -5.
Answer is : a = 1, b = -8, c = -5.

What is the correct answer of 1/3
serious [3.7K]
The correct answer of 1/3 is the decimal form of it which is 0.3 repeated (you can put a line on top of the 3). If not just leave it as 1/3 it is simplified as a fraction.

Please solve this quick 8n+7=31
emmasim [6.3K]

Hello there!

To find the value of n, work to isolate it from all other terms in the equation.

8n+7=31 - Start by subtracting 7 from both sides. 8n + 7 - 7 = 31 - 7

8n = 24 Next, divide both sides by 8 to finish isolating n. 8n÷8 = 24÷8

n = 3

This is your final answer.

I hope this was helpful and have a great rest of your day!

:)
