Answer:
C, y=-2/3x+1
Step-by-step explanation:
using points (0, 1) and (3, -1) obtained from the graph:
slope = -1-1/3-0 = -2/3
use one of the points above lets take (1, 0) and another point (x,y)
slope = y-0/x-1 = -2/3
y=-2/3x+1
Use your calculator:-
= 12^0.2 - 75 ^ 1/3
= -2.573 to the nearest thousandth
Step-by-step explanation:
a) 4 , 7 , 10 , . . . . .
Here we can see that ,
- Common difference = 10-7 = 3
- First term = 4.
We know the formula of nth term as ,
Sum of 20 terms as ,
b) -15 , -8 , -1 . . . . .
Here we can see that ,
- Common difference = -8+15 = 7.
- First term = (-15).
We know the formula of nth term as ,
Sum of 20 terms as ,
