<span>area of a circle = pi * r^2
radius (r) = half the diameter = 3.5 units
area = 3.14 * 3.5^2 = 38.47 units so thats wat it means</span>
Answer:

Answer:
65 mph
Step-by-step explanation:
To find the unit rate (miles per hour), we can use the equation
Where
r=rate (miles per hour)
d=distance (in miles)
t=time (in hours)
Using the given information, we can plug in
So, our equation is
When we divide 97.5 and 1.5, we get
So,
In conclusion, the rate (miles per hour) is 65 mph.
Step-by-step explanation:
Key : Plug in the numbers given in the parenthesis into the x values of the corresponding functions.
f(1/2) = 1/ 1/2 - 4 = 1/-7/2 = -2/7
g(1/2) = 1/1/2 - 2 = -3/2
f(-1/4) = 1/-1/4-4 = 1/-17/4 = -4/17
g(-1/4) = 1/-1/4 - 2 = 1/-9/2 = -2/9
