Answer:
15
Step-by-step explanation:
Answer: so i think for part a , the first term is a subscrpit 0 which is 10. Then the formula for any term in the sequence is Ao x R ^n. So R =2 so
1st term = 10 ( 2^0)= 1
2nd term = 10 (2^1) =20
3rd term = 10 (2^2)= 40
4th = 80
5th = 160
Part B
The limit as n approaches infinity for a sub n when R is 0, 1 and 2. THE LIMIT FOR R of 0, 1 and 2 is infinity.
Part C...i will have to research...sorry

Answer:
slope = 5
Step-by-step explanation:
The slope is the rate of change of the function. Although not mathaticaly rigorous, the slope of the line is the same as the slope of an uphill road. It's just a number that shows you how much the function change for every tiny step you take to the right. In order to calculate it, given that we are talking about a line which slope is constant, you have two pick two points. The slope is the difference of their y coordinates, divided by the difference of their x coordinates.
For example let's pick the following two points:
A(0,0) and B(1,5)
slope = ( y_B - y_A ) / ( x_B - x_A )
= ( 5 - 0 ) / ( 1 - 0 ) = 5
However, the above is a mechanism you can follow even when the exercise is a tough one.
To sum up, the slope is a number that shows you how much tilted is the graph. For every step to the right, how much does the value of the function change?
Hope i helped ;)
