Answer:
v in (-oo:+oo)
1.13/64 = (11/8)*v // - (11/8)*v
1.13/64-((11/8)*v) = 0
(-11/8)*v+1.13/64 = 0
0.01765625-11/8*v = 0 // - 0.01765625
-11/8*v = -0.01765625 // : -11/8
v = -0.01765625/(-11/8)
v = 0.01284091
v = 0.01284091
Step-by-step explanation:
sin 90 is simply 1, pretty straightforward
Hi!
We know that a radius is a line that reaches from point A (the middle of a circle) to point B (the outer part of the circle).
Based on that information, the sentence that describes the radius the best is It is a segment from a point on the circle to the center of the circle.
Hope this helps! :)

We'll use Cramer's rule for 2 equations:
ax + by = e
cx + dy = f
5x -3y = 18 a=5 b=-3 e=18
2x + 7y = -1 c=2 d=7 f=-1
denominator determinant (dn) = (a * d) - (c * b) = 5 * 7 - (2 * -3) = 41
x = [(e * d) - (f * b)] / dn
[18 * 7 - (-1 * -3)] / 41 =
123 / 41 = 3
y = [(a * f) - (c * e)] / dn
= (5 * -1) -(2 * 18) / 41 =
-41 / 41 = -1

The answer is 1,525$
This is because:
70 * 20 = 1,400
1,400 + 125 = 1,525
