The polynomial f(x) leaves a remainder of - 3 and - 7 when divided by (3x - 1) and (x +1) respectively.

olga55 [171]

Step-by-step explanation:

Here, f(x) is the given polynomial.

By remainder Theorem,

When divided by (3x-1),

f(1/3) = -3........(1)

When divided by (x+1),

f(-1) = -7.........(2)

Another polynomial is 3x²+2x-1

Solving,

3x²+2x-1

= 3x²+3x-x-1

=3x(x+1)-(x+1)

=(3x-1)(x+1)

f(x) = (3x-1)(x+1)Qx + (ax+b)

For f(-1),

-7 = -a+b

b= a-7

For f(1/3),

-3 = a/3+b

or, -3 = a/3+a-7

or, 4×3 = 4a

or a = 3

Also, b = 3-7 =-4

Hence, remainder is (3x-4)

Distances in space are measured in light-years. The distance from Earth to a star is 6.8 × 1013 kilometers. What is the distance

baherus [9]

I light year = 9.46 x 10¹² km

-------------------------------------------------------------------------------------
Find the number of light years
-------------------------------------------------------------------------------------

$\text {Number of light years = } \dfrac{6.8 \times 10^{13}}{9.46 \times 10^{12}}$

$\text {Number of light years = } 7.18$

-------------------------------------------------------------------------------------
Answer: The distance from Earth to the star is 7.18 light-years.
