Answer:
A. The approximate y intercept appears to be about 1.8 (slightly less than 2). What this tells us is that someone with 0 months of practice could expect to win around 1.8 games.
B. Using slope intercept form and assuming that the y intercept is at (0, 1.8), the equation can be solved for by finding the slope first and then putting the slope and the y intercept into the equation.
Slope (m):
points (0, 1.8) and (1, 3.0)
(Y2-y1)/(x2-x1)=(3.0-1.8)/(1-0)=1.2/1=1.2
Equation:
Y=mx+b
Y=1.2x+1.8
Step-by-step explanation:
Answer:
$8 per hour
Step-by-step explanation:
Total amount earned by Lily in two days = $54
Number of hours worked on day 1 = 2.5
Number of hours worked on day 2 = 4.25
Total number of hours worked in two days = 2.5 + 4.25 = 6.75
Let the amount earned by Lily per hour = x
Then
=>
=>
Hence the amount earned by Lily or Naomi per hour is $8.
1) We have to calculate the first derivative:
y=2x²+2
y´=4x
2) the slope at the point x=3; will be f´(3);
f´(3)=4(3)=12
answer: the slope will be 12.
Answer:
-12
Step-by-step explanation:
What it means by f(-1) is that x is -1.
So all you do is plug -1 into the x areas like this: -3(-1)^2+2(-1)-7=-12.
