Answer:−√33/7
Step-by-step explanation:
Second quadrant implies cos negative, as cos is projection from
unit circle to x axis.
sin^2+cos^2=1
cos= sqrt(1-sin^2)
sin^2 = 16/49
1-sin^2 = 33/49
sin= -sqrt(33)/7
Answer:
11 m - 20 m
Step-by-step explanation:
Answer:

Step-by-step explanation:
1) Rewrite the words into an equation:
÷ 4
2) Change the division sign to a multiplication sign and find the reciprocal of 4 (flip the numerator and denominator of 4):

3) Change the mixed number into an improper fraction:

4) Multiply:

Answer:
y = (-5/3)x+20
Step-by-step explanation:
Parallel lines have the same slope.
If you are doing division, you should be able to turn the equation around as a fact family, making it multiplication. All you need to do is 17x73=y.
y=1241
