Answer:
B
Step-by-step explanation:
-t²+4t+5=0
t²-4t-5=0
t²-5t+t-5=0
t(t-5)+1(t-5)=0
(t-5)(t+1)=0
t=5,-1
when t=0,d=5
actual time it it is in air=5-1=4 seconds.
Answer:

Step-by-step explanation:
we are given 8 songs
2 are <em>rock.</em><em> </em>4 are <em>reggae</em>, 2 are <em>country</em>
we want to figure out the probability of getting both reggae songs
notice that, they aren't replacing thus it's an independent probability
recall that,

P(A) represents the chance of getting our subject first time and P(B|A) represents the chance of getting the same subject second time
let's figure out P(A)
we have 2 reggae songs
and total 8 songs
therefore

let's figure out P(B|A)
since we took a reggae song before now we have only a reggae song
and total 8-1=7
therefore

Altogether

simplify multiplication:

And we are done!
(See attached graphic)
Total = 3,000 * (1 + .048/2)^2*2
Total = 3,000 * (1.024)^4
Total = 3,000 *

Answer:
21.27 cubic meters
22.30 cubic meters
Step-by-step explanation:
We find volume by multiplying height, width, and length.
21.
3x3x3=27 cubic meters
22.
5x2x3=30 cubic meters
