I NEED HELP PLEASE, THANKS! :) Heather invests $4,900 in an account with a 3.5% interest rate, making no other deposits or withd
Alex

Answer:    $5,828.28

<u>Step-by-step explanation:</u>

Use the Compound Interest formula:     A=P(1+\frac{r}{n})^{nt}       where

  • A is the accrued amount (balance)
  • P is the principal (initial amount invested)
  • r is the interest rate (in decimal form)
  • n is the number of times compounded each year
  • t is the time of the investment (in years)

Given: P = 4,900

           r = 3.5% (0.035)

           n = 2

           t = 5

A=4,900\bigg(1+\dfrac{0.035}{2}\bigg)^{2(5)}\\\\\\.\qquad = 4900(1.0175)^{10}\\\\\\.\qquad = \large\boxed{5,828.28}\\

Help pleasee asaapp im lost
avanturin [10]

Answer:

C

Step-by-step explanation:

The area of a circle is pi * r^2.  The radius is 7 because the diameter is 14 so the radius is 14/2.  The square of 7 is 49.  Pi is approximately 3.14, so 49 * 3.14 is about 154.

Roman55 [17]

Answer:

The correct answer is B) y = 1/6x + 4

Step-by-step explanation:

Since the slope of the original line is -6, we are looking for a line with a slope of 1/6. This is because perpendicular lines have opposite and reciprocal slopes. B is the only answer that satisfies that situation.
