Answer:
1 real zero; 2 complex zeros
Step-by-step explanation:
A cubic will have 3 zeros. The number of positive and negative real zeros can be determined using Descartes' rule of signs.
There are no sign changes in the coefficients of the function as written, so there are no positive real roots. (+++)
If odd-degree terms have their sign changed, then there is one sign change. (-++) That indicates there is one negative real root.
The remaining two roots will be complex.
_____
A graphing calculator can confirm this.
Answer:
$0.1395
Step-by-step explanation:
$2.79 x 0.05 = 0.1395
Given:
is the angle bisector of 
.
To find:
The measure of 
.
Solution:
It is given that is the angle bisector of . It means
...(i)
Now,
[Using (i)]
Divide both sides by 2.
Therefore, the required value is .
Answer: You can say that the slope is negative since the graph is decreasing.
Step-by-step explanation:
For f(-2), x will equal -2.
Plug the x-value into the equation:
A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):
Solve the problem:
f(-2) will equal
1/2.
