Answer:
87: y = 5
88: y = 0
89: y = -2
90: y = -1/2x + 9
91: y = 2x - 16
92: y = x - 11
Step-by-step explanation:
To find the slope(m): (y1 - y2)/(x1 - x2)
To find the y-intercept:
y = mx + b
Replace m with the slope and x and y with one of the sets of coordinates. Then simplify to get the y-intercept. Use the equation y = mx + b and replace m with the slope and b with the y-intercept to get the equation.
(Sorry if this is a little confusing.)
We can find the radius by using the formula: C = 2(pi)(r)
We'll use 3.14 for pi.
And solve for r.
18.84 = 2(3.14)r ; Start
18.84 = 6.28r ; Multiply 3.14 by 2
3 = r ; Divide both sides by the coefficient of r. Which is 6.28
So, the radius is 3 miles.
This is just about similar triangle
mn=2jl=22
mo=2lk=26
jk=2on=40
Step-by-step explanation:
The first set is equivalent.
We obtain the right-hand side by swapping places of the terms.
