The correct answer is A). None
Step-by-step explanation:
The given quadratic polynomial has 3 roots and some of roots are x=
and x=6+i
It is necessary to note that one of the roots is a complex number and root of complex number always in pair of the conjugate to each other.
Since x=6+i
Conjugate of (6+i) is (6-i)
<em>Therefore, (6-i) is 3rd required root of a polynomial </em>
<em>The correct answer is A). None</em>
Answer:
0.8 hours
Step-by-step explanation:
From the question;
- Speed of Min-jun is 27 miles per hour
- Distance covered is 21 miles
We need to determine the time he takes to cover the distance given;
We need to know that;
Speed = Distance ÷ time
Rearranging the formula;
time = Distance ÷ speed
Thus;
Time = 21 miles ÷ 27 miles per hour
= 7/9 hours
= 0.8 hours
Thus, he took 0.8 hours to cover the distance covered
Out of 170 students in 12th grade, 27+23 = 50 students have more than 1 college in mind.
So 50/170, or 29% is your answer.
Answer:
y = -5x + 4.
Step-by-step explanation:
y = mx + c is the general form
- where m = the slope of the line and c is the y-value where the graph cuts the y-axis.
The graph passes through the points (0, 4) and (1, -1) so the slope
= (Y2 - y1) / (x2 - x1)
= (-1-4) / (1-0)
= -5 = m.
and c = 4.
