Answer:
The slope of tangent at point (1,-2) is 
.
Step-by-step explanation:
The given equation of ellipse is
Differentiate both sides with respect to x.
Calculate the value of \frac{dy}{dx} at (1,-2).
Therefore the slope of tangent at point (1,-2) is .
Answer:
One standard deviation above the mean means a z-score of 1.0. If we put this into the calculator as normalcdf(1,999) = .159
15.9 percent of the athletes would have a distance greater than 20.56 meters.
Now multiply the number of athletes by the percent.
.159 * 40 = 6.346 = about 6 athletes
c. about 6 athletes
Answer:
six and one over twelve
Step-by-step explanation:
1/4 + 5 5/6=1/4+35/6 = 6 1/12
