Answer:
Just took the test,
1)d, 3
2)a, -13
3) c, y=-2x+6
4) c, f'(a)=8a+2
Step-by-step explanation:
For #3, graph f(x)=-x^2+5. Next graph y=-2x+6. You will see that the added equation touches at exactly the point (1,4). this make it the tangent line equation
Answer:
B 2:1
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, and
. The distance between them is given by:
In this question:
The length of the segments are given by the distance between its endpoints.
Line segment AB on the coordinate plane stretches from (1,1) to (7,9).
So its length is:
Line segment CD stretches from (-2,3) to (2,6).
What is the ratio AB:CD of the lengths of these line segments?
10:5 = 2:1
So the correct answer is given by option B.
