Answer:
C(-3,1)=X1,Y1
D(5,6)=X2,Y2
Step-by-step explanation:
(distance)^2=(X2-X1)^2+(Y2-Y1)^2
=64+25
=89
Answer:
b = - 0.432
Step-by-step explanation:
It takes 200 seconds to produce the first widget. And by the 400th widget, it takes only 15 seconds.
Now, the formula that gives the time to make the nth widget is given by
and we have to evaluate the constant b from the above-given conditions.
So, 
⇒ 
Taking log on both sides
b log (400) = log (0.075)
⇒ b = - 0.432 (Answer)

Answer:
A reflection in the x-axis and a vertical stretch by a factor of ½.
Step-by-step explanation:
The parent function is f(x).
The transformed function is

The negative sign means a reflection in the x-axis.
The 2 multiplying inside means a horizontal stretch by a factor of

Therefore the transformation, is a reflection in the x-axis and a vertical stretch by a factor of ½.
