Answer:
r = 75 mi; A = 17 671 mi²
Step-by-step explanation:
(a) Graph
The equation for a circle is
x² + y² = r²
Your equation is
x² + y² = 5625 = 75²
The graph is a circle with a radius of 75 mi.
(b) Broadcast area
A = πr² = π × 75² = π × 5625 ≈ 17 671 mi²
Answer:
you use ur fingers
Step-by-step explanation:
put a few fingers up and then put another few fingers up and then u put them together.
STEPS:
1. Using your straightedge, draw a reference line, if one is not provided.
2. Copy the side of the square onto the reference line, starting at a point labeled A'.
3. Construct a perpendicular at point B' to the line through ab2.
4. Place your compass point at B', and copy the side of the square onto the perpendicular b'g. Label the end of the segment copy as point C.
5. With your compass still set at a span representing AB, place the compass point at C and swing an arc to the left.
6. Holding this same span, place the compass point at A' and swing an arc intersecting with the previous arc. Label the point of intersection as D.
7. Connect points A' to D, D to C, and C to B' to form a square.
Answer:
graph the inequality on desmos and it will show you the answer
they all multiple by 4 like y 2/4+ 4y- 21
