First plug 32 in for x 14(32)t=46
Now solve for t
448t=46
T=46/448 which can be simplified to 23/224
Answer:
22.5
Step-by-step explanation:
If you expand the series, you can see the first few terms of the series:
- Putting 1 in
, 
- Putting 2 in
, 
- Putting 3 in
,
- Putting 4 in
,
We can see the series is 0, 0.5, 1, 1.5, ....
This is an arithmetic series with common difference (the difference in 2 terms) 0.5 and first term 0.
We know formula for sum of arithmetic series:

Where,
denotes the nth partial sum
is the first term (in our case it is 0)
is the term (in our case it is 10 since we want to find 10th partial sum -- sum until first 10 terms)
is the common difference (difference in term and the previous term) (in our case it is 0.5)
Substituting these into the formula, we get the 10th partial sum to be:

So the sum of the first 10 terms is 22.5. Third answer choice is right.
Answer:
its kinda dificult to explain (easier to show) but ill do my best
Step-by-step explanation:
so for part a you wanna start from the bottom (min) and go acros to the line above 1 then go three lines up for cookies. you should be on 3, 1
for part b its c lin decorates 21 cookies in 7 min
The correct answer would be : Slope : 3/2 and Y-Intercept : −3
I hope that this helps you !
