Answer:

Below in bold.

Step-by-step explanation:

Total surface area = 1/2 * area of a sphere + area of the side o a cone

=  1/2 * 4 π r^2 + π r L

= 1/2 * 4 π 7^2 + π*7*25

=  307.876 + 549.779

= 857.65 in^2 to nearest hundredth.

The figure shows the letter Z and four of its transformed images—A, B, C, and D:
tiny-mole [99]

Given:

The figure shows the letter Z and four of its transformed images—A, B, C, and D.

To find:

Which of the following rules will transform the pre-image of Z in quadrant 2 into its image in quadrant 1?

Solution:

From the figure it is clear that the pre-image of Z in quadrant 2 and its image in quadrant 1 (image A) are the mirror image of each other along the y-axis.

It means the pre-image of Z in quadrant 2 reflected across the y-axis to get the image in quadrant 1.

If a figure reflected across the y-axis, then rule of transformation is

(x,y)\to (-x,y)

So, the rule (x,y)\to (-x,y) transform the pre-image of Z in quadrant 2 into its image in quadrant 1.

Therefore, the correct option is c.
