Answer is 19;
Problem
a1=325 , d=25 , S19=?
Result
S19=10450
Explanation
To find S19 we use formula
Sn=n2⋅(2a1+(n−1)⋅d)
In this example we have a1=325 , d=25 , n=19. After substituting these values into the above equation, we obtain:
Sn19=n2⋅(2a1+(n−1)⋅d)=192⋅(2⋅325+(19−1)⋅25)=192⋅(650+18⋅25)=192⋅(650+450)=192⋅1100=10450
Answer:
0.234523452345 as a fraction equals 234523452345/1000000000000
Step-by-step explanation:
To write 0.234523452345 as a fraction you have to write 0.234523452345 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.234523452345 = 0.234523452345/1 = 2.34523452345/10 = 23.4523452345/100 = 234.523452345/1000 = 2345.23452345/10000 = 23452.3452345/100000 = 234523.452345/1000000 = 2345234.52345/10000000 = 23452345.2345/100000000 = 234523452.345/1000000000 = 2345234523.45/10000000000 = 23452345234.5/100000000000 = 234523452345/1000000000000
The slope of the line may be calculated by using the formula:
m = (y2 - y1)/(x2 - x1), where m is the slope, and (x1, y1) and (x2, y2) are two points on the line.
Using the points (0, -1) and (2, 4) shown, we can substitute these values into the formula above to get:
m = (y2 - y1)/(x2 - x1)
m = (4 - (-1))/(2 - 0)
m = 5/2
Therefor, the slope is 5/2.
Another way to think about the slope is in terms of rise/run, that is for a given interval that the x-value 'runs', by how much does the y value 'rise'?
Here, if we take the same two points (0, -1) and (2, 4), we can see that the x-value has moved 2 units, and the y-value has increased by 5 units. Thus:
if slope = rise/run, then the slope would be 5/2
Note that you should be careful when using this method if the y-value decreases as x increases; in this scenario, the 'rise' would be a negative value rather than a positive one
Answer:
Step-by-step explanation:
Okay so. im not good at explaining. but ill try my best
you go with your basic X over Y soooo 2X you would go up 2 because its a positive number. and to the.. left 3 becuse it - if it was a + you would go to the right 3 but sense its -3y you go to the left
so fare your going to go from the -9 point on your graph up 2 over 3
and if its just Y ots over 1
i really hope this makes sence and helps
