Answer:
-0.25 or -¼
Step-by-step explanation:
-20c = 180
-20c/-20 = 180/-20
c = -0.25 or -¼
Answer:
B. (-1,13)
Step-by-step explanation:
Given translation
(x,y)→(x-2,y-6)
moves point 2 units to the left and and 6 units down.
If a point after this translation has coordinates (-3,7), then its preimage has coordinates (-1,13) (translate the image point 2 units to the right and 6 units up to get preimage point).
Answer: 5,520
Step-by-step explanation:
Multiply 460 by 12. 12 is one dozen.
Answer:
Count how many numbers you have. If you have an odd number, divide by 2 and round up to get the position of the median number. If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.
The range is calculated by subtracting the lowest value from the highest value.

Step-by-step explanation:
½ [cos(a − b) − cos(a + b)]
Using sum and difference formulas:
½ [cos a cos b + sin a sin b − (cos a cos b − sin a sin b)]
Distribute the negative:
½ (cos a cos b + sin a sin b − cos a cos b + sin a sin b)
Combine like terms:
½ (2 sin a sin b)
Simplify:
sin a sin b
