What decimals and what grid
Answer:
1) 8
2) -2
3) 6
Step-by-step explanation:
1) First, find the pattern in the table, with X the pattern is +1, but with Y the pattern is +2. So to find the Y-intercept in the table you need to subtract 1 from X and subtract 2 from Y. The answer is 8.
2) On a graph it is really easy, it is where the line touches the Y-axis, in this case, it is -2. The answer is -2.
3) With the equation y=mx+b, the M is the rise/run and the B is the Y-intercept, and the B in the equation is 6. The answer is 6.
1.6 times 10 to the 5th power
Average velocity = (x(4) - x(2))/(4 - 2) = ((4 + 2(4)^2) - (2 + 2(2)^2))/2 = ((4 + 2(16)) - (2 + 2(4)))/2 = ((4 + 32) - (2 + 8))/2 = (36 - 10)/2 = 26/2 = 13m/s.
