Answer: 6630
Step-by-step explanation:
Given , Number of documentaries = 17
Number of children's movies = 20
Total movies = 17+20=37
Number of combinations of r things taken out of things = 
Now, the number of different combinations of 3 movies can she rent if she wants at least one documentary
= (1 documentary+2 children's movies , 2 documentary+1 children's movies , 3 documentary+0 children's movies)


Hence, the number of different combinations of 3 movies can she rent if she wants at least one documentary is 6630 .
Answer:
4080 ft
Step-by-step explanation:
34 yards of ribbon are used to prepare 8 teddy bears. The yards of ribbon used to prepare 320 teddy bears are:
320 teddy bear × (34 yard/8 teddy bear) = 1360 yard
1 yard is equal to 3 feet. The feet corresponding to 1360 yards is:
1360 yard × (3 feet/1 yard) = 4080 feet
8sr6 + 2sr2×2×3 +5sr3 - sr2×3×3×3
=8sr6 + 2(2)sr3 + 5sr3 - 3sr2×3
=8sr6 + 4sr3 + 5sr3 - 3sr6
=8sr6 - 3sr6 + 4sr3 +5sr3
=5sr6 + 9sr3 (ans)
You need to find the slope too.

point slope formula y - y1 = m(x - x1)
use (0, -3)
y - (-3) = 1 (x -0)
y + 3 = 1x
