19/x=sin 20
19/sin 20=x
x=55.5522836
Answer:
E' (-2,5)
F' (-3,1)
G' (-2,-1)
H' (0,3)
Step-by-step explanation:
The rule for 90 degree clockwise rotation is (h,k) -> (k,-h). This means flip the x-value's sign and then switch x and y's position. For example E (-5,-2), first flip x's sign (5,-2) and then switch x and y's places (-2,5).
To find one tenth of 119.9 just divide 119.9 by 10
Answer:
D. 
Step-by-step explanation:
We graph the points on the graph. The graph is attached.
Let us take two points (1, 14) and (15, 1), and calculate the slope
between them <em>(we choose these points because the line passing through them will be the best fit for all points) </em>

Thus we have the equation

Let us now calculate
from the point 


So the equation we get is

Let us now turn to the choices given and see which choice is closest to our equation: we see that choice D.
is the closest one, so we pick it.
Answer:
0
Step-by-step explanation:
We have the two functions:

And we want to find (f-g)(144).
This is the same thing to f(144)-g(144).
So, let’s determine the value of f(144) and g(144) first:

And:

Hence:

Our final answer is 0.
