Find the balance in the account. $800 principal earning 7%, compounded annually, after 4 years

Mathematics
1 answer:
Arturiano [62]2 years ago
5 0
Formula for amount, A, in Compound Interest:

A = P(1 + r)ⁿ

Where P = Principal = $800,  r = rate per year = 7% = 0.07, n = number of years = 4

A =  P(1 + r)ⁿ

A =  800(1 + 0.07)⁴

A = 800(1.07)⁴             Use your calculator

A ≈   1048.6368

A ≈ $1048.64

HELP ASAP <br> What is the slope of the line on the graph?
ollegr [7]
The slope of this line is -1/6.  

2 Point:     (6,2)         (-6,6)
                   x₁ y₁         x₂ y₂
       

Remember: 
  
    rise          change in y          y₂ - y₁          6 - 2            4
 ---------- =  ------------------- = ------------- = ----------- = ----------
    run            change in x         x₂ - x₁         -6 - 6          -12


Simplify 4/-12

     4 ÷ 4             1
  -------      = ------------- = -1/3
   -12 ÷ 4          -3

The slope of the line is -1/3.

Let x1 = 12, y1 = 15, and y2 = 3. Let y vary inversely with x. Find x2.
vladimir1956 [14]

Answer:

x2 = 60

Step-by-step explanation:

If the variables x and y are inversely proportional, the product x * y is a constant.

So using x1 and y1 we can find the value of this constant:

x1 * y1 = k

12 * 15 = k

k = 180

Now, we can use the same constant to find x2:

x2 * y2 = k

x2 * 3 = 180

x2 = 180 / 3 = 60

So the value of x2 is 60.
