The domain, since t<0 has no real context, is from zero to the time, t, when the height is equal to zero. Height equals zero when:
-5t^2+20t+50=0 using the quadratic equation for simplicity:
t=(-20±√1400)/-10, since t>0 when h=0
t=(-20-10√14)/-10
t=2+√14 seconds
t≈5.74 seconds
So the domain is:
t=[0, 2+√14]
t≈[0, 5.74] (to the nearest hundredth of a second)
Step-by-step explanation:
0.4(5×-15+2.5×+7.5)use 2.5 to multiply the inner bracket
use 0.4 to multiply the equation in the bracket
2x-6+1+3
2×-5+3
2×-2
since there is no" equal to "sign this is the final answer
The Answer is 21/50 which is = 0.42
Answer:
2/299
Step-by-step explanation:
there were 300 tickets and 1 is out . 299 tickets left
There were 3 prizes and 1 is out. 2 prizes left.
The probability of winning ANY prize when next ticket is drawn is
P(prize) =2/299
Answer:
For this case we have the following variable:
x: the number of cookies Cameron made.
Therefore, the number of cookies Deyonne makes is:
(x + 0.25x)(x+0.25x)
Then, the total sales revenue is:
P = 0.5 * (x + (x + 0.25x))P=0.5∗(x+(x+0.25x))
Rewriting we have: P = 0.5 * (2.25x)P=0.5∗(2.25x)
P = 0.5 * (2.25x)P=0.5∗(2.25x)
P = 1.125xP=1.125x
