there isnt a list of options given but should be something like
38 + 35 + 22 = 22 + 35 + 38
or maybe
38r + 35t + 22l = 22l + 35t + 38r
it equals 95
Answer:5n+6
Step-by-step explanation :an=a1+d(n-1)
=1+(-5)(n-1) or 1+-5n+5
an=-5n+6
"<span>Terrance trains at the rate of 6 miles every half an hour and Jesse trains at the rate of 2 miles every 15 minutes. How long will each person take to run of a total of 50 miles at the given rates?"
I will treat this as two problems: Terrance's case and Jesse's case.
Terrance's rate is (6/.5) mph, or 12 mph, and Jesse's is (2/0.25) mph, or 8 mph.
At this rate, Terrance can run 50 miles in how many hours? Divide 50 miles by 12 mph: (50/12) hours, or (25/6) hours, or 4 hours 10 minutes.
At his won rate, Jesse can run 50 miles in (50 mi) / 8mph hours,
which reduces to 25/4 hours, or 6 1/4 hours.</span>
Answer:
Growth rate = 8% = 0.08
Initial value (Po) = $255
F(t) = Po* e^rt
F(t) = $412.09897
Step-by-step explanation:
Given that:
Initial cost = $255
Rate of increase per year (r) = 8% = 0.08
Growth rate :
Final amount = Initial amount * (1 + rate)^time
Growth rate = 8% = 0.08
Initial value (Po) = $255
Exponential model for the cost :
F(t) = Initial value * e^(rate * time)
F(t) = Po* e^rt
Value after 6 years :
F(t) = Po* e^rt
t = 6
F(t) = 255 * e^(0.08*6)
F(t) = 255 * 1.6160744
F(t) = $412.09897
Your answer is 1/5 Hope this helps :D
