Mathematics
1 answer:
kodGreya [7K]3 years ago
3 0

Answer:

70%

Step-by-step explanation:

Maths homework takes 1/6×150mins

=150/6=25 mins

science homework takes 20/100×150

=3000/100

=30mins

Language Arts homework uses 1/3×150

=150/3

=50 mins

percent of time left for Marsha's social studies homework=total time used / original time

=(25+30+50)mins

=105mins/150mins×100%

=0.7×100

=70%

What are the possible rational zeros of f(x) = 3x4 + x3 - 13x2 - 2x + 9?
zalisa [80]
Rational roots theorem states that any rational root will be a factor of the constant over a factor of the leading coefficient.
The given equation is: <span>f(x) = 3x^4 + x^3 - 13x^2 - 2x + 9. </span>In this case, it is a factor of 9 over a factor of 3. 

<span>Factors of 9: ±1, ±3, ±9 </span>
<span>Factors of 3: ±1, ±3 </span>

So possible rational roots are: ±1, ±3, ±9, ±1/3
