Answer:
40m^2 152.6m^2
Step-by-step explanation:
has two points of discontinuity at 
, where 
.
We have
so as long as 
, we can cancel 
and be left with 
. Then as 
, we have
The limit exists, so the discontinuity at -1 is removable (so definitely not C or D).
Meanwhile,
does not exist, so the discontinuity at 1 is non-removable, making A the correct answer.
Answer:
220.5
Step-by-step explanation:
First, we can figure out the half circle. The area for that is pi times r squared divided by 2. So the area is 8 squared times pi divided by 2. So 64 divided by 2 is 32. 32 times pi is 100.530964915. We can round that to 100.5 and now the rectangle is 8 times 15. Which is 120. So 120 plus 100.5 is 220.5! I hope this helps! Please mark me Brainliest!!!
Answer:
6 times
Step-by-step explanation:
The theoretical probability of scoring 10 points upon pressing a button = 3 / 5
The expected number of times 10 points is scored if button is pressed 10 times :
This will be ;
(Number of times button is pressed * theoretical probability of scoring 10 when button is pressed)
(10 * 3 / 5)
= 30 / 5
= 6 times
