The turtle`s speed:
v t = 12 miles / hour = /*5,280
= 63,360 ft / hour = / : 3
= 21,120 yards / hour = / : 60
= 352 yards / minute
The boy`s speed:
v b = 4.4 ft/ s = / * 60/3
= 4.4 * 20 yards / minuet = 88 yards / minute
v t : v b = 352 : 88 = 4
The turtle swims 4 times faster than the boy.

(a equals negative twelve)
Answer:
C!
Step-by-step explanation:
So, it's actually very simple!
If you don't know, the domain of a function is the set of x-values that make the equation true. The range, which we are trying to find, is the set of f(x), or y values that are possible.
Now, notice how in the graph, y-values don't go below 1. So there is our limit. There is nothing else limiting the y-values the other way, so its basically a single equality.
y=1 is included in the function, of course, as it goes on y=1.
So, it's 
Hope this helps!
Answer:
use a calculator the variable is the angle of a triangle
Step-by-step explanation:
X2 - 12 = y, where x=the number of hours since 7 am, and y=the water level
