Answer:
"To the nearest year, it would be about 9 years"
Step-by-step explanation:
11c)
This is compound growth problem. It goes by the formula:
![F=P(1+r)^t](https://tex.z-dn.net/?f=F%3DP%281%2Br%29%5Et)
Where
F is the future amount
P is the present (initial) amount
r is the rate of growth, in decimal
t is the time in years
Given,
P = 20,000
r = 8% = 8/100 = 0.08
F = double of initial amount = 2 * 20,000 = 40,000
We need to find t:
![F=P(1+r)^t\\40,000=20,000(1+0.08)^t\\2=(1.08)^t](https://tex.z-dn.net/?f=F%3DP%281%2Br%29%5Et%5C%5C40%2C000%3D20%2C000%281%2B0.08%29%5Et%5C%5C2%3D%281.08%29%5Et)
To solve exponentials, we can take Natural Log (Ln) of both sides:
![2=(1.08)^t\\Ln(2)=Ln((1.08)^t)](https://tex.z-dn.net/?f=2%3D%281.08%29%5Et%5C%5CLn%282%29%3DLn%28%281.08%29%5Et%29)
Using the rule shown below we can simplify and solve:
![Ln(a^b)=bLn(a)](https://tex.z-dn.net/?f=Ln%28a%5Eb%29%3DbLn%28a%29)
We can write:
![Ln(2)=Ln((1.08)^t)\\Ln(2)=tLn(1.08)\\t=\frac{Ln(2)}{Ln(1.08)}\\t=9.0064](https://tex.z-dn.net/?f=Ln%282%29%3DLn%28%281.08%29%5Et%29%5C%5CLn%282%29%3DtLn%281.08%29%5C%5Ct%3D%5Cfrac%7BLn%282%29%7D%7BLn%281.08%29%7D%5C%5Ct%3D9.0064)
To the nearest year, that would be about 9 years
Answer:
These fractions are already in simplest form.
Step-by-step explanation:
You answer is false because the 25 is almost equal to 28 have a nice day
A pair of perpendicular lines would be line CF and line AJ.
Line BC and line AJ are NOT perpendicular because when a pair of lines are perpendicular, all angles become 90 degrees. It is obvious, in the case, if you were to slide line BC on top of line AJ, the angles will not equal 90 degrees.
The x4 would have to be in the parentheses while the -3 would have to be on the outside because you are subracting 3 from 48
