If the endpoints of AB have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of AB?

Answers

Answer 1
Answer: The midpoint of a line segment given the coordinates of the endpoints may be obtained by getting the average of the two abscissas and ordinates. With the given above, the average of the abscissas is 4 and that of the ordinates is 3. Thus, the midpoint is at (4, 3).

Answer and Step-by-step explanation:

Answer:

The cross section will be an isosceles triangle

Step-by-step explanation:

The image of the inquiry in the joined figure N 1

we realize that

On the off chance that a plane goes through the pivot of revolution of the cone, at that point the resultant cross-area will be a triangle with one vertex as the vertex of the cone and the different sides of the triangle through the vertex A will be equivalent.

Where the base of the triangle will be equivalent to the breadth of the round base of cone and the two compatible sides of triangle will be equivalent to the inclination tallness of the cone

hence

The cross segment will be an isosceles triangle

Find the area of each sector.
*Geometry

Answers

The area of the sector in the diagram is 1805π/8 km².

What is area?

Area is the region bounded by a plane shape.

To calculate the area of the sector, we use the formula below

Formula:

  • A = πr²∅/360......................... Equation 1

Where:

  • A = Area of the sector
  • r = Radius of the sector
  • ∅ = Angle of the sector

From the question,

Given:

  • r = 19 km
  • ∅ = 225°

Substitute these values into equation 1

  • A = π×19²×225/360
  • A = 1805π/8 km²

Hence, the right option is B. 1805π/8 km²

Find the slope of the line through each pair of points (20,18),(-9,-14)

Answers

 the slope = ( -14 - 18 ) / ( -9 -20 ) = (-32)/(-29) = 32/29.
(Y2-y1)/(x2-x1)
(-14-18)/(-9-20)
-32/-29
=32/29

the slope is 32/29
