Area of sector................................
sveticcg [70]

Answer:

A ≈ 25.1 cm²

Step-by-step explanation:

the area (A) of the sector is calculated as

A = area of circle × fraction of circle

  = πr² × \frac{\frac{4\pi }{9} }{2\pi }

  = π × 6² × \frac{\frac{4\pi }{9} }{2\pi }

  = 36π × \frac{\frac{4\pi }{9} }{2\pi }

  = 18 × \frac{4\pi }{9}

  = 2 × 4π

  = 8π

  ≈ 25.1 cm² ( to the nearest tenth )

What is the slope of the line? 3x-4y=73x−4y=7
Andrei [34K]
To find the slope, we put this in y = mx + b form where m is ur slope.

3x - 4y = 7.....subtract 3x from both sides
-4y = -3x + 7 ...now we divide both sides by -4
(-4/-4)y = (-3/-4)x + (-7/4)...simplify
y = 3/4x - 7/4

y = mx + b
y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope

A line with a slope of 4 passes through the point (2, 1 ). What is the equation of this line?​
castortr0y [4]

Answer:Put this in y= mx +b form

we have the slope(4) as well as a set of points for x and y so we have everything we need to solve for b

1= 4(2) + b

1 =8+b   B=-7

so equation is y = 4x -7
