Answer:
Step-by-step explanation:
Let be the equation of the circle. We know that must be iqual , due to the canonical equation of the circle is , but we can think as an unknown for the moment.
In order to determine the equation of the circle we have to find the coefficients . In addition, we have that are point on this circle. Furthermore, If is any point in circle, then the following equations are satisfied:
Here the unknowns are . According with a result of linear algebra, the system has a nontrivial solution if and only if the determinant of the matrix of coefficients is zero, then we have that
Calculating this determinant we obtain the equation:
Simplifying:
Firstly , we need to draw diagram
we are given
opposite =300
adjacent =750
now, we can use tan formula
now, we can find x
we get
so,
angle of depression is 21.8 degree.....Answer
Answer: <em>f(x) </em>is a polynomial. The degree is 5 and the leading coeficient is -7.
Step-by-step explanation:
1. By definition a polynomial is the sum of terms that consist of a number (which is called "coefficient") that multiplies a variable with an exponent (This exponent is a whole number). Therefore, the function is a polynomial.
2. To find the degree of the polynomial you must see the greatest exponent. In this case, this is 5. Therefore, the degree is 5.
3. The leading coefficient is the number that multiplied the variable with the greatest exponent. Therefore, the leading coefficient is -7.
