Step-by-step explanation:
Quadratic function is function of the form where a, b and c are real numbers and
A number is said to be a rational number if it can be written in the form where u and v are integers and
.
A number is said to be a complex number if it can be written in the form u+iv where u and v are real numbers.
A number 'a' is said to be a zero of a function P(x) if
We know that if zero of a fraction is of form u+iv then its other zero is u-iv.
As 3+7i is a zero of the function, 3-7i is also its zero.
So, given equation is
Answer: If they worked together, it would take 31.5 minutes
Step-by-step explanation:
There's a certain formula for equations like this:
t1= the time it took for the first person to complete the task.
t2= the time it took for the second person to complete the task.
tb= the time it took for both of them to complete the task.
We have the values for both t1 and t2, but not for tb.
t1= 45
t2= 105
tb= x
Now it's simple algebra, and all we need to do is solve for x
The LCM for both fractions is 315, so now we multiply BOTH sides of the equation by 315.
This will simplify nicely, so now we just need to get x on the other side.
