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:
it increases
Step-by-step explanation:
The steepness of the slope for directly proportional relationships increases as the value of the constant m (y = mx) increases. In our two speed examples, the change in steepness of slope represents the change in speed or the change in the unit rate.

Answer:
x = 1 in
Step-by-step explanation:
We can use ratios to solve since they are similar triangles
6 6+x
----- = ---------
5 6
Using cross products
6*6 = 5*(6+x)
36 = 30+6x
Subtract 30 from each side
36-30 = 30-30+6x
6 = 6x
Divide each side by 6
6/6 = 6x/6
1 =x
