Answer: C=14π≈43.98 ft
Step-by-step explanation:
To find the circumference of the circle, we use the equation C=2πr or C=πd. These 2 equations are equivalent because 2r is the same as d, diameter. In this case, we can use C=πd because the problems already gives us the diameter.
C=πd
C=14π≈43.98 ft

Using implicit differentiation, it is found that y is changing at a rate of 10 units per second.
---------------------
The equation is:
Applying implicit differentiation in function of t, we have that:
- x-values changing at a rate of 2 units per second means that
- Point Q(1,4) means that .
We want to find , thus:
y is changing at a rate of 10 units per second.

48 miles per hour! Just double 30 minutes to get an hour, and double 24 as well which equals 48.
Answer:
2 2/9 hours
Step-by-step explanation:
So
2/5+1/20=1/x
now solve for x
2 2/9
Y-intercept is (0,-0.7)
x-intercept is (-1.2,0)
