Answer:
(2/5)√5 ≈ 0.894427
Step-by-step explanation:
You require the y-coordinate of the point that satisfies two equations:
x^2 +y^2 = 1
y = 2x
Substituting for x, we have ...
(y/2)^2 +y^2 = 1
y^2(5/4) = 1
y^2 = 4/5
y = (2/5)√5 ≈ 0.894427
The sine of the angle is (2/5)√5 ≈ 0.894427.
For this case we substitute the point in each of the equations and verify if the equality is met:
Option 1:
It is not true
Option 2:
It is not true
Option 3:
Is fulfilled
Option 4:
Answer:
The point belongs to the equation of the third option.
Answer:
Yes
Step-by-step explanation:
If you subtract the p4 and p2 you get p2. q5-q2 is q3. 39/3 is 13. Therefore those expressions are equivalent.
5, 5 1/3, 5 2/3, 6, 6 1/3, 6 2/3, 7
Answer=
y=-3+3
y=0
the sum of -3+3 is zero.
