Answer:
Step-by-step explanation:
It's actually 6 cm. This is because the diameter of the smaller circle is 12pi/pi which is 12, and the diameter of the bigger one is 18pi/pi which is 18. 12 + 6 = 18, so the diameter increases by 6.
Perpendicular has slope that multiplies to -1
y=mx+b
m=slope
y=-1x+11
-1 times what=-1?
what=1
y=x+b
find b
given
(-2,3)
(x,y)
inpus -2 for x and 3 for y
solve for b
3=1(-2)+b
3=-2+b
add 2 to both sides
5=b
y=x+5 is equation
not listed, but the choices are all wrong
Answer: 5x^2 + 3x + 1
Step-by-step explanation:
1.) Put the two equations together into an addition problem.
<em>3x^2 + 4x + 2x^2 - x + 1</em>
2.) Combine like terms.
<em>3x^2 + 2x^2 = 5x^2</em>
<em>4x - x = 3x</em>
<em>1 = 1</em>
3.) Order the like terms together.
<em>5x^2 + 3x + 1</em>
