tana =m. or tanA=(+ or- m1-m2/1+m1 *m2
Answer: The tangent to a curve at a point is a straight line just touching the curve at that point; the slope of the tangent is the gradient of that straight line.
52
Step-by-step explanation:
39, 40, 44, 49, 50, 54, 56, 61, 62, 68
39, 40, 44, 49, <u>50, 54,</u> 56, 61, 62, 68
= = 52
d=~7.6
7^2+3^2=d^2
49+9=d^2
58=d^2
Square root of 58=~7.6
It is unlikely that they will be the same rank 2/52 chance witch is a 0.03% chance
What the what???????
C 58
