What is the balance after 15 years in a savings account that earns 2% interest compounded bimonthly when the initial deposit is
Ierofanga [76]

Answer:

$1348.07

Step-by-step explanation:

Hello!

<h3>Compound Interest Formula: A = P(1 + \frac rn)^{nt}</h3>
  • A = Account Balance
  • P = Principle/Initial Amount
  • r = Rate of Interest (decimal)
  • n = Number of times compounded (per year)
  • t = Number of Years

<h3>Given Information</h3>
  • Account Balance = ?
  • Principle Amount = $1000
  • Rate of Interest = 0.02

Why is the Rate 0.02?

This is because we are gaining money, so the multiplier should be greater than 1. We already added 1, which is 100% so you simply add the 0.02 for the extra 2%.

  • Number of times compounded per year = 6

This is because it is being compounded bi-monthly, or once every 2 months. 12 months divided by 2 months is 6 months, so 6 times a year.

  • Number of years = 15

<h2>Solve </h2>

Solve by plugging in the given values into the formula.

  • A = P(1 + \frac rn)^{nt}
  • A = 1000(1 + \frac {0.02}{6})^{6*15}
  • A = 1000(1 + 0.00333...)^{90}
  • A = 1000(1.00333...)^{90}
  • A = 1000(1.145743)
  • A \approx 1457.43

This is really close to the first option, and since there is rounding involved with the repeating decimal, the first option should be correct.

The answer is $1348.07.

Sophie Ruth is eating a 50-gram chocolate bar that contains 30%, cocoa. How many grams of cocoa is in the chocolate bar?
Salsk061 [2.6K]

Answer:

We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):

0.30*50 = 15 g

There are 15 grams of cocoa in the chocolate bar.

Compute the average rate of change of g(x)=x^2-1/4 between x=1 and x=3
AURORKA [14]
Average Rate Of Change- It's Really Just The Slope, And We Can Use The Fancy Formula Below, But That's Unnecessary, We Can Just Find Two Coordinate Points

\frac{g(x + h) - g(x)}{h}
X=1
g(x) =  {x}^{2}  -  \frac{1}{4}  \\ g(1) = (1)^{2}  -  \frac{1}{4}  \\ g(1) =  \frac{3}{4}  \\ (1, \frac{3}{4} )
x=3
g(x) =  {x}^{2}  -  \frac{1}{4}  \\ g(3) = (3)^{2}  -  \frac{1}{4} \\  g(3) = 9  -  \frac{1}{4} \\ g(3) =  \frac{35}{4}  \\ (3, \frac{35}{4} )
Slope
\frac{y_2-  y_1}{x_2-  x_1}
(1, \frac{3}{4} ) \\ (3, \frac{35}{4} ) \:

\frac{ \frac{35}{4} -     \frac{3}{4} }{3-  1}  \:  =  \frac{ \frac{32}{4} }{2}  =  \frac{32}{4}  \times  \frac{1}{2}  =  \frac{32}{4}  = 8
