Answer:
7.127
Step-by-step explanation:
Hope this helps!
The compound interest is given by:
A=p(1+r/100)^n
where;
A=amount
p=principle
r=rate
n=time
therefore the time taken for Felicia's money to double will be:
350=175(1+4/100)^n
350/175=1.04^n
2=1.04^n
therefore introducing natural longs we get:
ln2=nln1.04
n=(ln2)/(ln1.04)
n=17.7 years
The answer is 17.7 years

Step-by-step explanation:
<span>y=-40x+100 This equation says your friend lives 100 miles away and travels 40 miles per hour. He takes 2.5 hours to get there.
y = -40x + 100 If y=0 then x = 100/40 = 2.5 hours and if x=0 then y=100.
You are 150 miles away and it takes you 2.5 hours to get there so your equation is:
0 = -2.5v + 150 You are solving for velocity.
v = 150/2.5 = 60 miles per hour. Now we can write the answer to the problem.
y = -60x + 150 Compare that to the original statement.
y = -40x + 100 Your buddy's speed is 40 and yours is 60. He has 100 miles to go and you have 150. Otherwise it's the same equation.</span><span>
