Answer:
25.63694268 = r
Step-by-step explanation:
The circumference is
C = 2*pi*r
161 = 2*(3.14) *r
161 = 6.28 r
Divide each side by 6.28
161/6.28 = r
25.63694268 = r
Answer:
y = -1/2x - 1
Step-by-step explanation:
We can use the point-slope form of the equation:
y-y1 = m(x-x1)
Where the given y1 = -2, x1 = 2, and m = -1/2. This yields:
y - (-2) = -1/2(x - 2)
y + 2 = -1/2x + 1
y = -1/2x +1 - 2
y = -1/2x - 1
The slant height, x, is 7.5 mm because you use the pythagorean formula and solve for c, since the you're solving for the hypotenuse which is the longest side.
4b^2 - 16 =
4(b^2 - 4) =
4(b + 2)(b - 2)
