Answer:
C. Reflecting over the y-axis and then translating to the right 8 units
Step-by-step explanation:
Reflection over the line x=4 gives you the transformation ...
(x, y) ⇒ (2·4 -x, y) = (-x +8, y)
This is precisely the same transformation you get by reflection over the y-axis:
(x, y) ⇒ (-x, y)
followed by translation to the right 8 units:
(-x, y) ⇒ (-x +8, y)
__
Reflection over x=4 is the same as reflection over y and translation right 8.
True only if it is tangent in 4 areas
I believe the correct answer is .03
Answer:
A
Step-by-step explanation:
The velocity of a moving body is given by the equation:
Is the velocity is <em>positive </em>(v>0), then our object will be moving <em>forwards</em>.
And if the velocity is negative (v<0), then our object will be moving <em>backwards</em>.
We want to find between which interval(s) is the object moving backwards. Hence, the second condition. Therefore:
By substitution:
Solve. To do so, we can first solve for <em>t</em> and then test values. By factoring:
Zero Product Property:
Now, by testing values for t<1, 1<t<4, and t>4, we see that:
So, the (only) interval for which <em>v</em> is <0 is the second interval: 1<t<4.
Hence, our answer is A.
