6x-2 because there are 6 eggs per packet and x packets and 2 are gone
6x-2= 28
6x= 30
x=5 so 5 packets
Base area = πr²
πr² = 169π
r² = 169π/π = 169
r = √169 = 13 cm
h = r + 4 = 13 + 4 = 17 cm
volume of the cylinder = πr²h = 169π * 17 = 2873π cm³
Answer:
n(t) = 10×1.2^t
Step-by-step explanation:
The idea here is that the number of ill students is multiplied by 1+20% = 1.20 each hour. That is, after t hours, you have multiplied the original number by 1.20 "t" times. Of course, repeated multiplication is signified using an exponent.
The form you can use in such cases is ...
value = (initial value)×(growth factor in period)^(number of periods)
Here, you're given a growth rate (20% per hour), so you add 1 to get the growth factor (as we showed above).
Your exponential function can be ...
n(t) = 10×1.20^t
It’s the second one I think
