Answer:
33
Step-by-step explanation:
An = 6n+3
so the first five terms in sequences is A5= 6*5 +3 = 33
Answer:
probably the 2.38 seconds answer
Step-by-step explanation:
start by setting the entire equation equal to 8, since h(t) is the height and 8m is the height we are looking at right now.
subtract 8 from both sides to get:
use the Quadratic equation to find the time, the negative answer does not count.
when you do the quadratic equation you get
In decimal form that's about 2.38 and 0.42 You'd probably go with the 2.38 seconds because the ball starts at 0 seconds, so the lower number is probably to close to the start point.
I haven't touched on mean, mode, medium, and range in a little while so I could be wrong, but if (mean) means average, i think average is adding 2 grades together then dividing the number of exams, so the average needs to be 90, so what I did was i found the difference between the original grade on the first exam, so 90-86=4, so i guessed at 94 being the next grade needed. (86+94)/2=90. 86+94=180 then divide 180 by 2 and it equals 90. so yeah your answer is 94.
You can say:
0.78 = 78/100 = 39/50 :)))
i hope this is helpful
have a nice day
