Let
rA--------> radius of the circle A
rB-------> radius of the circle B
LA------> <span>the length of the intercepted arc for circle A
</span>LB------> the length of the intercepted arc for circle B
we have that
rA/rB=2/3--------> rB/rA=3/2
LA=(3/4)<span>π
</span>
we know that
if <span>Both circle A and circle B have a central angle , the ratio of the radius of circle A to the radius of circle B is equals to the ratio of the length of circle A to the length of circle B
</span>rA/rB=LA/LB--------> LB=LA*rB/rA-----> [(3/4)π*3/2]----> 9/8π
the answer is
the length of the intercepted arc for circle B is 9/8π
Answer:
y-5=-2/3(x-(-7))
Step-by-step explanation:
I just learned this recently as well so bare with me.
So the point slope form is y-y1=m(x-x1)
So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4
So now, we just have to plug in the numbers.
So y-5=-2/3(x-(-7)).
I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.
I hope this helped.
Answer:
Step-by-step explanation:
Well 7 is the only number that can be divided by itself and 1
If the question is 6x-30, then the answer is 6(x-5)
Have a great day ^_^
