We have the formula S= r * theta , where S is arc length , r is radius , and theta is central angle in radians
So AB= 4 * 45* π/180 = π units
Converting decimals:
Write down the decimal divided by 1, like this: decimal 1.
Multiply both top and bottom by 10 for every number after the decimal point. ...
Simplify (or reduce) the fraction.
They both are similar because you can divide by one? not sure on this part.
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 4, - 1)
m =
=
= 
Use either of the 2 points for (a, b)
Using (a, b) = (- 4, - 1), then
y - (- 1) =
( x - (- 4)), that is
y + 1 =
(x + 4)
Plot the points you found in part (b) on a suitable set of coordinates and draw a line through them. It might help your accuracy to use the y-intercept of 20 also.
