a.) (3,3) (3,9) (9,3)
b.) (0,0) (0,6) (6,0)
c.) (3,3) (0,9) (9,0)
d.) (0,0) (0,9) (9,0)

Explanation:

The original three vertices are A = (0,0), B = (0,3) and C = (3,0). Each point is formed by reading the columns from top to bottom.

Multiply those coordinates by 3

A = (0,0) turns into A ' = (0,0) ... ie there's no change here

B = (0,3) turns into B ' = (0, 9)

C = (3,0) turns into C ' = (9, 0)

The three points A', B', and C' are three times further away from the origin compared to the original points A, B, C.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
