Answer:
Option 4
The term that represents the amount of time that the money is accruing interest is 'x'.
Step-by-step explanation:
Given : The function below represents the annual interest Alexander earns on a savings account.
To find : Identify the term that represents the amount of time that the money is accruing interest ?
Solution :
The general annual interest formula is
Where, A is the amount
P is the principal
r is the interest rate
t is the time
The annual interest Alexander earns on a savings account is
Comparing with general formula,
t=x
The term that represents the amount of time that the money is accruing interest is 'x'.
Therefore, Option 4 is correct.
Write the given equation as
x = (1/2)y² or as y = √(2x)
Graph the given curve within the region (0,0) and (2,2) as shown in the figure below.
When the curve is rotated about the x-axis, an element of surface area is
dA = 2πy dx
The surface area of the resulting solid is
![A= 2\pi \int_{0}^{2} \sqrt{2x} dx = \frac{4 \sqrt{2} \pi}{3} [x^{3/2}]_{0}^{2} = \frac{16 \pi}{3}](https://tex.z-dn.net/?f=A%3D%202%5Cpi%20%5Cint_%7B0%7D%5E%7B2%7D%20%20%5Csqrt%7B2x%7D%20dx%20%3D%20%20%5Cfrac%7B4%20%5Csqrt%7B2%7D%20%5Cpi%7D%7B3%7D%20%5Bx%5E%7B3%2F2%7D%5D_%7B0%7D%5E%7B2%7D%20%3D%20%5Cfrac%7B16%20%5Cpi%7D%7B3%7D%20)
If the right end is considered, the extra area is π*(2²) = 4π
Answer:
The surface area of the rotated solid is (16π)/3.
If the right end is considered, it is an extra area of 4π.
x = (1/2)y² or as y = √(2x)
