A $4,000.00 principal earns 5% interest, compounded annually. After 4 years, what is the balance in the account?
denis23 [38]
First question:
interest rate is 5% annually. After 4 years relative value of interest will be 1.05^4
Now we multiply that with starting funds and get
4000* 1.05^4 = 4862.03

Second question:
Because interest is 8% semiannually that means that after 35 years relative value of interest will be   1.04^(35*2)
6000*1.04^70 = 93,429.71

Third question:
after first year tractor's value will be 0.86*15450. After 3 years its value will be:
(0.86)^3*15,450 = 9,827.07

an verage person has 6x10^2 times as many red bloods cells as white blood cells. A small sample of blood has 7x10^3 white blood
m_a_m_a [10]

Answer:

4.2 x 10⁶

Step-by-step explanation:

The problem says that there are 6x 10² times as many red blood cells as white blood cells. This means that you will need to multiply the given number of white blood cells, which is 7 x 10³ by 6x 10².

To do this, first you multiply the coefficients:

7 x 6 = 42

Next you combine the exponents of the 10s, because their bases are the same, we just add the exponents when you multiply them and copy the base:

10² x 10³ = 10⁵

So the result would be:

42 x 10⁵

However the following the form of scientific notation, you need to move the decimal one more time so that means you add one more to the exponent of 10.

4.2 x 10⁶
