-- When Riko left the house, Yuto was 5.25 miles ahead of her.
-- From the time she left the house, she gained (0.35 - 0.25) = 0.1 mile on Yuto
every minute ... closing the gap at the rate of 0.1 mile per minute.
-- If she can keep it up, she'll close the gap in (5.25 / 0.1) = 52.5 minutes.
-- Riko is behind her brother when 0 ≤ t < 52.5 minutes .
Answer:
C. 62
Step-by-step explanation:
ADC is 90 degrees. 90 - 28 = 62
Answer:
A
Step-by-step explanation:
The end behaviour as x gets larger and positive ( right- hand end )or larger and negative ( left- hand end )is determined by the term of the greatest degree.
For p(x) that is 4
, with
• Even degree (8) and positive leading coefficient (4), then
as x → ∞ , p(x) → ∞ and
as x → - ∞ , p(x) → ∞
The probability of the union of two events is the sum of their probability, minus the probability of their interserction:

If we plug the known values into this formula, we have

From which we can deduce

So, the probability of
is a bit less than
, we have to take away all events that belong to B as well:
