Answer:
<u>False</u>: C. Completing the square can be used to solve the given equation.
Step-by-step explanation:
First of all, no equation is given. Any answer that suggests a way of finding solutions to the given equation will be false.
The statement of B is debatable. The method of completing the square is most often used for quadratics, but might reasonably be applied in any situation where a perfect square can be created by regrouping the terms.
Statements A and D essentially say the same thing. Both are true. That fact makes statement C false. Statement C is the one you're looking for.
Answer:
AC is about 41. 095 miles long.
Step-by-step explanation:
You can use the Law of Cosines to solve this: c^2 = a^2 + b^2 – 2ab cos(C)
Substitute in your values, and you're good to go!
c^2=16^2+28^2-2(16)(28)(cos(117))
c^2 = 256 + 784 - 896(cos(117))
c = sqrt(1040 - 896(cos(117)))
c is about 41. 095 miles long.
Answer:
C
Step-by-step explanation:
3 5/9 is the equavilent to 3.5555555556
This decimal is closet to C because you'd have to round up to make the decimal only in the tenths place
Hope it helps! Good luck!
