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

Answer:

-14x² + 7x + 42

Step-by-step explanation:

(2x + 3)(x - 2) = 2x² - 4x + 3x - 6  =  2x² - x - 6

-7(2x² - x - 6) = -14x² + 7x + 42

Help please Algebra 2 B
jok3333 [9.3K]
The degree of this polynomial is 3, so it has to have 3 roots or 3 zeros.
If it has one non-repeated x-intercept, that means that this polynomial has ine real zero.
So, it needs 2 more, and this 2 are complex zero.

Correct answer is B. One real and 2 complex zeroes.
