Answer:
5.8496 min
Step-by-step explanation:
[tex]\displaystyle t=\frac{10}{\ln{2}}\int_{220}^{280}{\frac{1}{T-100}}\,dT=\frac{10(\ln{(280-100)}-\ln{(220-100)})}{\ln{2}}=\frac{10\ln{(3/2)}}{\ln{2}}\\\\\boxed{t\approx5.8496\quad\text{min}}[/tex]

Solve 7x- c = k for x
Answers
Answer:
D
Step-by-step explanation:
I know the answer is D because I set the equation to be equal to x.
First, I added c to both sides. The equation looked like: 7x=k+c
Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7
In conclusion, the answer is D. x=k+c/7

A person invested $420 in an account growing at a rate allowing the money to double
every 10 years. How long, to the nearest tenth of a year would it take for the value of
the account to reach $960?
Answers
Answer:
t=11.9
Step-by-step explanation:
960=420(2)^t/10
2.28571429=2^t/10
add log to both sides
log(2.28571429)=10 t log(2)
divide by log 2
1.19264508= 10 /t
10(1.19264508)
