It would be $24.50. An easier way if it’s going up by a constant amount, you can multiply! So you would just multiply 7 hours by $3.50 per hour (7 x $3.50 = $24.50)
So F(6) means 6 on the x axis then look to see where the graph is on the Y axis,
in this case on x 6 y=4
Since length*width=area, (x+12)*width=x²-144. Dividing (x+12) from both sides, we get (x²-144)/(x+12)=width. One formula we can use is that
(a²-b²)=(a-b)*(a+b). Since 144=12², that means that x²-144=(x-12)*(x+12). Plugging that in, we get (x-12)*(x+12)/(x+12)=(x-12)=width

Answer:
Step-by-step explanation:
cos^-1(6/13)=62.5136°
sin(2*62.5136°)=0.8189
cos(2*62.5136°)=-0.5740
