The radius of the circle is 28
Answer: x = -3.5
Step-by-step explanation:
Since they are similar they should have the same ratio, so if four equals two, then 5 equals 2.5. Then you solve the equation 2.5 = x+5, to find x.

Step-by-step explanation:
The domain is the horizontal extent. Since there are arrows on both ends of the graph, the horizontal extent is from -∞ to ∞.
The range is the vertical extent. The graph shows a minimum at y=-2, which value is in the range. Expressed in interval notation, it is [-2, ∞).
Please note that the "end behavior" of y tends to +∞ in for either direction of x.

The graph is "increasing" where it has positive slope, for 3 < x. It is "decreasing" where it has negative slope, for x < 3.
The graph is positive where it is above the x-axis. The points on the x-axis are not part of the "positive" interval(s). You will note there are two intervals where the graph is positive. It isn't difficult to find the answer choice that is a union of two intervals.
The graph is negative where hit is below the x-axis. Again, the points at x=1 and x=5 are not part of that interval, so it is expressed using curved brackets.
Say for example we have segment A with endpoints coordinates of (a,b) and (x,y) and we wish to divide the segment into parts. The ratio of division is assumed to be r. In this case, we identify the first coordinates of the segment next to (a,b) by:
(c,d) = ((x-a)/r + a , (y-b)/r + b)
This formula is used including the constant portion of the division of the segment, (x-a)/r. The addition, a, can vary depending on the position of the coordinates to be taken. On the other end, before (x,y), the coordinates should be
(v,w) = (y - (x-a)/r , z - (y-b)/r )
Answer:
It B since The root is obtained when F(x)=0 and if F(x)=y this means y=0 and when you look art graph the y=0 presented in two points x=-4 and x=2
