1g = 1000mg
Answer:
the vertical bar "|"
Step-by-step explanation:
Sorry if it's wrong.
Let
rA--------> radius of the circle A
rB-------> radius of the circle B
LA------> the length of the intercepted arc for circle A
LB------> the length of the intercepted arc for circle B
we have that
rA/rB=4/7--------> rB/rA=7/4
LA=(1/2)π
we know that
if 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
rA/rB=LA/LB--------> LB=LA*rB/rA-----> [(1/2)π*7/4]----> 7/8π
the answer is
the length of the intercepted arc for circle B is 7/8π
The answer to the question is 6/9.
Answer is 1st option
16x²-81
(4x)² - 9²
Thus it is the difference of squares of 4x and 9
Factorising (4x)² - 9² , we would get:
(4x + 9)(4x - 9)
As a² - b² = ( a + b)(a - b)
