15.51
Step-by-step explanation:
tens ones. tenths hundredths thousands
1 5. 5 0 6
To round to the nearest hundredth, we look at the thousandths place
Since is it 5 or higher(6) we round the hundredths place up
15.506 becomes 15.51
Answer:
the duration of this event is 4 hours
Step-by-step explanation:
This function is a quadratic one
let Δ be the dicriminant :
- a = -16
- b = 48
- c= 64
- Δ = 48²-4*(-16)*64 = 6400
so there are two values that satisfy -16t²+48t+64 = 0 x and y
- x= (-48+80)/-16*2 = -1
- y= (-48-80)/-16*2= 4
x<0 so w won't take it since time is a positive value here
so t = y = 4h
