Answer:
311.41 degrees
Step-by-step explanation:
If 4 sin Ф = -3 and Ф is between 0 and 360 degrees, then we conclude that Ф must be either in Quadrant III or Quadrant IV (because the sine is negative).
Let's assume we're in Quadrant IV. Then sin Ф = opp / hyp = -3/4; that is, the opp side is negative and has length 3, and the hypo is positive 4.
According to the Pythagorean Theorem, (-3)^2 + x^2 = 4^2, or,
x^2 = 16 - 9 = 7.
Then x is either √7 or -√7.
To find the angle Ф, use the inverse sine function:
Ф = arcsin (-3/4). Using a calculator we get the angle -40.59 degrees, which corresponds to (360 degrees - 40.59 degrees), or 311.41 degrees. We can check this by finding the sine of 311.41 degrees; the result is -0.75, which matches "If 4sintheta = -3."
The coordinates of r is ( 4, -1 )
Answer:
It takes 20 minutes for each dog
Step-by-step explanation:
she wants to spend an equal amount of time with each dog she has 145 minutes to play with all 7 dogs
It takes 145 minutes to play with 7 dogs
for 7 dogs it takes 145 minutes
To find the time taken for 1 dog , divide 145 by 7

It takes 20 minutes for each dog
Answer:
opinion
Step-by-step explanation:
2 different sets of data can have the same mean:
for example
4, 5, 6 ---> has a mean of 5
2,6,7 ---> also has a mean of 5
hence it is NOT a fact that if the means are the same, that it must be the same data set
