Answer: P(t) = $1000*2^t
Step-by-step explanation:
Ok, we know that in the week 1 the price is: p = $1000
After one week, the price doubles, so here we have: p = 2*$1000
After another week, the price doubles again, here the price is:
p = 2*(2*$1000) = $1000*2^2
Here we already can see the relation, for each week, we multiply the previous price by two, which will increase the exponent in the two by 1 unit.
Then, for week number t, the price will be:
P(t) = $1000*2^t
Answer:
29.12%
Step-by-step explanation:
Given that :
A = 49
B = 50
C = 38
D = 60
E = 75
Total = (49 + 50 + 38 + 60 + 75) = 272
Pie chart % for each :
A = (49 / 272) * 360 = 64.85
B = (50 / 272) * 360 = 66.18
C = (38 / 272) * 360 = 50.29
D = (60 / 272) * 360 = 79.41
E = (75 / 272) * 360 = 99.26
Difference between C and D
(79.41 - 50.29) = 29.12%
Answer:
10 19/10 meters
Step-by-step explanation:
Step one:
given data
let the amount of string used for the soccer field be x
and the amount used for coach spot be y
Also, let the total string used be represented as T
Step two:
Hence the expression for the total is
T= x+y
T= 9 1/2+ 2 2/5
T= 9.5+ 2.4
T= 11.9
or
T= 119/10 meters
or
T= 10 19/10 meters
Answer:
3 hours
Step-by-step explanation:
288 ÷ 96 km/h = 3 hours
as time = distance ÷ speed
