Suppose that you have $1400 in a savings account. The bank pays 1.5% annual simple interest. What would be the interest paid aft
ICE Princess25 [194]

Answer:

You should have $1,463.95

Step-by-step explanation:

The formula for this is A=P(1+r)^x

P being the initial amount, r being the percentage, and x being the time passing.

<u>1. Write out the equation:</u> A=1400(1+0.015)^3

REMEMBER- writing percentages into decimals is moving the decimal point two times to the left--or dividing by 100!

<u>2. Parentheses:</u> 1400(1.015)^3

At this point, you're going to want to do exponents first (PEMDAS). If you're typing this into a calculator it should just give you the answer right away with the full equation.

<u>3. Answer:</u> 1463.95 (rounded to the nearest hundredth).

**I apologize if this is wrong; I haven't done it in a while so I don't know if I did 3 years or 3 months.. lol. That's probably not helping with the confidence level, but good luck!

Write an equation for the line parallel to the given line that contains C. <br> C (1,8); 5/7x + 7
Genrish500 [490]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{y = 5/7x + 51/7}

-------------------------------------------------------------------------------------------------------------

Given: \textsf{Goes through (1, 8) and is parallel to y = 5/7x + 7}

Find:  \textsf{Write an equation that follows that criteria}

Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7.  We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.

<u>Plug in the values</u>

  • \textsf{y - y}_1\textsf{ = m(x - x}_1\textsf{)}
  • \textsf{y - 8 = 5/7(x - 1)}

<u>Distribute</u>

  • \textsf{y - 8 = (5/7 * x) + (5/7 * (-1))}
  • \textsf{y - 8 = 5/7x - 5/7}

<u>Add 8 to both sides</u>

  • \textsf{y - 8 + 8 = 5/7x - 5/7 + 8}
  • \textsf{y = 5/7x - 5/7 + 8}
  • \textsf{y = 5/7x + 51/7}

Therefore, the final equation that follows the description that was provided in the problem statement is y = 5/7x + 51/7.
