Find the locus of the point (x,y) which is a distance 3 from the point (-2, 1)

Reptile [31]

Consider this option:
1. rule: Circle is the locus of the points which are on the same distance from the given point. Common view of the equation is: (x-a)²+(y-b)²=r², where r - the distance from the given point to the described locus, a&b - coordinates of the given point.
2. using item 1:
(x+2)²+(y-1)²=3² or (x+2)²+(y-1)²=9.

A sector with a radius of 15 cm has a central angle measure of 8π/5 what is the area of the sector

Inessa05 [86]

Answer:

area of the sector = 360π cm²

Step-by-step explanation:

To calculate the area of the sector, we will follow the steps below;

First write down the formula for calculating the area of a sector.

If angle Ф is measured in degree, then

area of sector = Ф/360 × πr²

but if angle Ф is measured in radians, then

area of sector = 1/2 × r² × Ф

In this case the angle is measured in radiance, hence we will use the second formula

From the question given, radius = 15 cm and angle Ф = 8π/5

area of sector = 1/2 × r² × Ф

=1/2 × 15² × 8π/5

=1/2 ×225 × 8π/5

=360π cm²

area of the sector = 360π cm²

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used.

Tamiku [17]

Step-by-step explanation:

(a-4) (a-5) = a^2 - 9a + 20

(a-10) (a-2) = a^2 - 12a + 20

(a-4) (a+5) = a^2 +a - 20

(a-10) (a+2) = a^2 -8a - 20
