Answer:
f'(-1)= 3
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)= (7-(-2))/(1-(-2))=9/3=3
Slope of the tangent line in the given point equals f' at this point.
So,
f'(-1)= 3
therefore, x = 59
Step-by-step explanation:
Here,
Mean (m) = 101
No. of terms (n) = 6
submission x (total) = 102+120+106+111+108+x
= 547 + x
Now, We know;
m = total / n
101 = 547 + x / 6
101 × 6 = 547 + x
606 - 54u = x
Hence , x = 59.
