Answer:
c) parabola and circle: 0, 1, 2, 3, 4 times
d) parabola and hyperbola: 1, 2, 3 times
Step-by-step explanation:
c. A parabola can miss a circle, be tangent to it in 1 or 2 places, intersect it 2 places and be tangent at a 3rd, or intersect in 4 places.
__
d. A parabola must intersect a hyperbola in at least one place, but cannot intersect in more than 3 places. If the parabola is tangent to the hyperbola, the number of intersections will be 2.
If the parabola or the hyperbola are "off-axis", then the number of intersections may be 0 or 4 as well. Those cases seem to be excluded in this problem statement.
Answer:
28
Step-by-step explanation:
180=90+x+2+2x+4
90=3x+6
84=3×
x=28
2y^4 and 5y^4 because same variable (y), same degree (3)
Answer:
The correct answer is:
1. Because of collinearity and supplementarity-
2. They remain along the same line.
3. The sum of them is 180 degrees.
4. Supplementarity.
5. The sum of the internal angles of a triangle is 180ª
6. Supplementarity and external angle theorem sum up the same.
7. Nothing.
Step-by-step explanation:
1. The reason why the exterior angle of 3 is 4, its because the last one is supplementary and collinear to the other.
2. Angle 3 and 4, form a collinear pair since they remain along the same line.
3. Angle 3 is supplementary to 4 because the sum of them is 180 degrees.
4. The sum of the angles are 3 and 4 is 180 because they are supplementary.
5. The sum of the angles mentioned is: 180 because of internal angle theorem.
6. It's like that because supplementarity and external angle theorem sum up the same. i.e, angle 1 + angle 2 + angle 3 = angle 3 + angle 4 =180
7. Nothing.
