Answer:
oh
Step-by-step explanation:
A)
y = mx + c
<span>y = 1x + 3
</span>
<span>y = x + 3
</span>
b)
y = 2x ? 5 comparing to y = mx + c, slope = m
slope = 2.
But for a perpendicular line, we take the negative reciprocal,
= -1/2 = -1/2
Call M the midpoint. The coordinate of this point is given by....
M=(x1+x2 /2, y1+y2 /2)
So (3,7)=(x1+0 /2, y1+ -5 /2). or
3= x1/2. or x1=6 and
7=y1-5 /2. or 14=y1-5 or y1=19
B is at the point (6,19)
Answer:
12π cubic inches
Step-by-step explanation:
Volume = (4/3)πr^3
V = (4/3)π9
V = (36/3)π
V = 12π
Is there supposed to be parentheses?
