Answer:

2. y = 7/2 x -2

3. y = 3/4x-1

Step-by-step explanation:

points (0,-2) (4,12)

slope = (y2-y1)/(x2-x1)

slope = (12--2)/(4-0)

= (12+2)/4

= 14/4 = 7/2

the slope is 7/2 and the y intercept is -2

y = mx+b

y = 7/2 x -2

points (0,-1) (4,2)

slope = (y2-y1)/(x2-x1)

slope = (2--1)/(4-0)

= (2+1)/4

= 3/4

the slope is 3/4 and the y intercept is -1

y = mx+b

y = 3/4x-1

in a circle a 60 sector has an area of 25 pi square feet. what is the circumference? leave your answer in terms of pi and in sim

belka [17]

The area of the sector is given by the equation,
A = πr²(x / 360°)
where x is the number of degrees in the figure.
25π ft² = (πr²)(60/360)
The value of r is 12.25 ft. Then, we use this value to calculate for the circumference of the sector.
C = 2πr(x/360)
Substituting,
C = 2π(12.45)(60/360)
C = 12.83 ft³
