Answer:
Equation C Equation A Equation D Equation B
Answer:
Step-by-step explanation:
The given parametric equations are;
We make t the subject in the second equation to get:
We substitute into the first equation to get:
We use the relation:
and
The function f(t) gives the amount of oil that leaks out as a function of time (t) where time is measured in minutes.
The total amount of oil that leaks out over some amount of time can be found by integrating f(t) over the interval of time. This of the integral as the sum of each of the amounts when we cut the time up in seconds, or milliseconds...though in reality the intervals are so small they are practically zero...this is why we use an integral rather than a simple sum.
The time is being measured in minutes so 2 hours is 120 minutes. Thus, the total quantity of oil that leaks out is given by
Be sure to use t (rather that the usual x) because your function is in terms of t.
Answer:
The solution is (-2,-11)
Step-by-step explanation:
The given system is
and
Make y the subject in the first equation to get;
Put into the second equation.
Group similar terms;
Put into .
This implies that;
The solution is (-2,-11)
<h3>Zeros of function are
</h3>
<em><u>Solution:</u></em>
<em><u>We have to find the zeros of the function</u></em>
Find the zeros of function:
We have two zeros
Thus zeros of function are
