Coordinates of the y-intercept is (0, -5)

Step-by-step explanation:

Step 1: Given the slope of the line, m = 3. Point on the line is (1, -2). Here x = 1 and y = -2. Substitute in the equation y = mx + b to find b.

⇒ -2 = 3 × 1 + b

⇒ b = -5

⇒ Coordinates = (0, -5)

A circle with radius 6 has a sector with a central angle of 48 what is the area of the sector

inn [45]

Answer:

≈ 15.08 units²

Step-by-step explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

= πr² × $\frac{48}{360}$ ( r is the radius )

= π × 6² × $\frac{48}{360}$

= 36π × $\frac{48}{360}$ = π × $\frac{48}{10}$ = $\frac{48\pi }{10}$ ≈ 15.08
