Answer:
3 units
Step-by-step explanation:
So if we want to know how high the spring board is, this will need to be the time at which the diver is still at the top of the board, in this case t = 0 seconds.
So we will need to find h(0)
- h(0) = 5(0)² + 10(0) + 3 = 0 + 0 + 3 = 3
16x
Step-by-step explanation:
6 increased by 2 --> 6+2
difference of 4 and 2 --> 4-2
first part times the second part --> 6 + 2 (4-2)
times a number --> • x
put it all together --> (6+2)(4-2) • x or 16x
Answer:
A
Step-by-step explanation:
Given
x² - 16x + 64 = 0 ← left side is a perfect square and factors as
(x - 8)² = 0, thus
x - 8 = 0 ⇒ x = 8 with multiplicity 2
Thus x = 8 is the only solution → A
Answer:
-5/4
Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
Given that Half of you want to go bowling and the other half want to go to a movie
So we must get probability for bowling = prob for movie
Option 1: Here P(HH) = 1/4 and P(no HH) = 3/4
SInce the two are not equal this is not fair
2) Here P(HT ) =1/4 and P(TH)=1/4 and other outcomes repeat the process
This is fine and hence this option is right
3) P(HHT) = 1/8 and P(TTT or HHH) =1/8+1/8=1/4
This is biased and hence not fair
4) P(HHH or TTT) = 1/4 and P(Other options)=3/4
Biased and hence not fair
Only option B is right.
