Issouf claims that the scale factor is 1/2. which statement about his claim is correct? a- he is correct because cb is 4 and c' b' is 2. the scale factor is c'b'/cb = 2/4 = 1/2b- he is correct because he needs to subtract 2 from each side. a reduction has a scale factor that is a fraction, so it must be 1/2c- he is incorrect because it is 3. cb is actually 2+4 or 6. so one needs to multiply the pre-image length by 3 to get the image; 3 is the scale factor. d- he is incorrect because the scale factor is 1/3. cb is actually 2 + 4 = 6. cb is the pre-image, so the scale factor is c'b'/cb = 2/6 = 1/3.

The correct option is D.

Step-by-step explanation:

It is given that Issouf claims that the scale factor is 1/2.

From the given figure it is clear that

The scale factor of a figure is

The scale factor is 1/3 because CB is actually 2 + 4 = 6.

Therefore the correct option is D.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
