Answer:
The fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. The roots are
.
Step-by-step explanation:
Consider the provided information.
Algebra's fundamental theorem states that: Every polynomial equation of degree n with complex coefficients has n roots in the complex numbers.
Now consider the provided equation.

The degree of the polynomial equation is 2, therefore according to Algebra's fundamental theorem the equation have two complex roots.
Now find the root of the equation.
For the quadratic equation of the form
the solutions are: 
Substitute
in above formula.





Hence, the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. The roots are
.
Answer:
c
Step-by-step explanation:
When we know two sides and the included angle, there is a formula we can use.
We know angle C = 35º, and sides a = 20cm and b = 19.5cm.
using the formula
Area =(½)ab sin C(angle)
Put in the values we know:
(20×19.5÷2)×sin(35)=
111.8474050885 cm^2
rounded = 111.85 cm^2
answer is c
If you want to find cosP , since angles Z and P are 2 complementary angles then cosZ is the same as cosP so you say the cosP=sinZ=4/5 (property of 2 complement angles in a right triangle)
Using the given equation:
10PI/X = 240/360
Cross multiply:
(10PI*360) = (240*X)
3600PI = 240X
Divide both sides by 240:
X = 3600PI / 240
X = 15PI in^2
