Answer:
geometric, with a common ratio of 1/2
Step-by-step explanation:
The sequence is geometric because you get successive trems by <u>multiplying</u><u> </u>the previous term by a certain constant, the 'common ratio'. (If you got each successive term by <u>adding</u> or <u>subtracting </u>the same constant number each time, that would be an arithmetic sequence.)
In this case, it looks like you get each successive term when you multiply the previous term by 1/2.
Thus, the common ratio is 1/2.
Answer to part A: 11w^2+7z^2
Answer to part B: 14w^2+9w
=================================================
Explanation:
For part A, the expression 4w^2+7w^2+7z^2 has one pair of like terms. That pair is 4w^2 and 7w^2 which combine to 11w^2. You add the coefficients to get 4+7 = 11, then tack w^2 onto everything to say 4w^2+7w^2 = 11w^2
We cannot combine 11w^2 and 7z^2 as they aren't like terms. So we leave it as 11w^2+7z^2
--------------------
In part B, the like terms are 15w and -9w. They combine to 15w-9w = 6w. You can think of it like 15-9 = 6 then stick a 'w' to each term. We cannot combine the w^2 term with the w terms.
Answer with Step-by-step explanation:
We are given that
Height of ball after t seconds is given by
a.Substitute the value of t=1
b.Differentiate w.r.t x
Again differentiate w.r.t t
Hence, the height is maximum at t=2.5 s
Maximum height of the baseball=27 ft
I think its aprox. $1.42 per pound.
Answer:
40
Step-by-step explanation:
The median is the middle number
There are 10 numbers
The middle is between 5th and 6th number
Take the 5th and 6th numbers and average them
(39+41)/2 = 80/2 = 40
The median is 40
