Answer:
3.7001 × 10 to the power of 4 is the answer for #1
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
Answer: <em>16%</em>
Let's assume that "X" % of 410 is 65.6.
Therefore, we can write this as;
X% of 410 = 65.6
![\frac{X}{100}\times 410 = 65.6](https://tex.z-dn.net/?f=%5Cfrac%7BX%7D%7B100%7D%5Ctimes%20410%20%3D%2065.6)
![X = \frac{65.6\times100}{410}](https://tex.z-dn.net/?f=X%20%3D%20%5Cfrac%7B65.6%5Ctimes100%7D%7B410%7D)
![X = 16](https://tex.z-dn.net/?f=X%20%3D%2016)
<em>16% of 410 is 65.6.</em>
The initial investment = $250
<span>annual simple interest rate of 3% = 0.03
</span>
Let the number of years = n
the annual increase = 0.03 * 250
At the beginning of year 1 ⇒ n = 1 ⇒⇒⇒ A(1) = 250 + 0 * 250 * 0.03 = 250
At the beginning of year 2 ⇒ n = 2 ⇒⇒⇒ A(2) = 250 + 1 * 250 * 0.03
At the beginning of year 3 ⇒ n = 3 ⇒⇒⇒ A(2) = 250 + 2 * 250 * 0.03
and so on .......
∴ <span>The formula that can be used to find the account’s balance at the beginning of year n is:
</span>
A(n) = 250 + (n-1)(0.03 • 250)
<span>At the beginning of year 14 ⇒ n = 14 ⇒ substitute with n at A(n)</span>
∴ A(14) = 250 + (14-1)(0.03*250) = 347.5
So, the correct option is <span>D.A(n) = 250 + (n – 1)(0.03 • 250); $347.50

Answer:
C. 0 ≤ y ≤ 7
Step-by-step explanation:
Range is the interval of the numbers on the y-axis. The numbers go from y-value 1 to y-value 7. Since the circles at the ends are closed, this means 0 and 7 are included in the range, so ≤ is included instead of <.
