ANSWER = c. 63°
EXP:
>ABC = 1/2(x + y)
Answer:
The first one is false - see below.
Step-by-step explanation:
The diagonals of the square are also diameters of the circle - True.
The diagonals of the square intersect at the centre of the circle - True.
The diagonals form 4 congruent arcs - True.
40% of 24 is 9.6 so that means it's 9.6 hours or 9 hours and 36 minutes.
Answer:
See image attached
Step-by-step explanation:
This type of transformation corresponds to a reflection of the function's graph around the x axis. Therefore one should obtain the mirror image of the segments on he upper quadrant as shown in red in the attached image.
Answer is choice C
"Dilate with a scale factor of two" means "multiply each coordinate by two"
A = (2,3) turns into A' = (4,6)
B = (3,5) turns into B' = (6,10)
C = (7,4) turns into C' = (14,8)
Side Note: this quick shortcut only works if the center of dilation is the origin (0,0). If the center of dilation isn't the origin, then you will have to do a translation (shifting) before you can use the trick, and then you'll have to shift back. The idea of the shifting is so that the center of dilation becomes the origin on a temporary basis. Because no mention is made of the reference center, it is assumed to be the origin by default.
