Answer:
x^2 +y^2 = 4y
Step-by-step explanation:
Using the usual translation relations, we have ...
r^2 = x^2+y^2
x = r·cos(θ)
y = r·sin(θ)
Substituting for sin(θ) the equation becomes ...
r = 4sin(θ)
r = 4(y/r)
r^2 = 4y
Then, substituting for r^2 we get ...
x^2 +y^2 = 4y . . . . . matches the first choice
Answer:
Three angles measuring 75, 45, and 60.
Step-by-step explanation:
The correct answer for this statement would be FALSE. Let us try to prove it by plugging in the values. So 2 (1/2) - 3 (1/3) <span> ≥ 5.
So that would be 1 - 3 </span><span> ≥ 5..
-2 </span><span> ≥ 5, which makes the result false because -2 is not more than or equal to 5, but instead, it is less than. I hope this answer helps. </span>
answer : 48
For the senior-class election, 8 candidates are running for president and 6 for vice-president.
the Fundamental Counting Principle states that if we have two events,
Event 1 occurs in 'm' ways and Event 2 occurs in 'n' ways
The total combination of events is m * n
8 candidates are running for president and 6 for vice-president
so total number of class combinations = 8 * 6 = 48
Answer = 48
