if $4000 is invested in an account that pays interest compounded continuously, how long will it take to grow to $8000 at 7%?

Archy [21]

So, since it is continuously, we need to think of PERT

$A=P\times e^{rt}$

So, we just plug our numbers in to solve for T

$8000=4000e^{.07t}\\\ln(8000)=\ln(4000e^{.07t})\\\ln(8000) = \ln(4000) + \ln(e^{.07t})\\\ln(8000)=\ln(4000)+.07t\ln(e)\\\ln(8000)=\ln(4000)+.07t\\\frac{\ln(8000)}{\ln(4000)}=.07t\\\frac{\ln(8000)}{.07\ln(4000)}=t\\ 15.479=t$

It will take 15.479 years

Help me find the mean of this data set.

Lina20 [59]

Answer:

Finding the mean is very simple, add them all together and divide that sum by the number of data points you have; in this case there are 45

Step-by-step explanation:

$\frac{74+67+74.25+64+72+...}{45}$ = mean

#1 Using the right triangle below, find the cosine of angle A.

motikmotik

Answer: 0.8

Step-by-step explanation:

Using the Cosine formula :

$Cos A = \frac{b^{2}+c^{2}-a^{2}}{2bc}$

$a = 6$

$b = 8$

$c = 10$

substituting into the formula , we have

$Cos A = \frac{8^{2}+10^{2}-6^{2}}{2(8)(10)}$

$Cos A = \frac{64+100-36}{160}$

$Cos A = \frac{164-36}{160}$

$Cos A = \frac{128}{160}$

Therefore :

Cosine of angle A = 0.8
