So 20=80%'
% means out of 100 so
80%=80/100 so
20=80/100
we try to get to 100/100 so
20=80/100
5=20/100
5 times 20=100 so
25=100/100
there were 25 questions total
If the term in the middle is 16x^2
6x^2-24x-16x^2-9x+1 =
-10x^2-33x+1
Answer:
— 4√16(cos(4π3)+isin(4π3))=2(cos(−π6)+isin(−π6))=√3−i. Explanation: De Moivre's formula tells us that: (cosθ+isinθ)n=cosnθ+isinnθ.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Since the inscribed angle theorem tells us that any inscribed angle will be exactly half the measure of the central angle that subtends its arc, it follows that all inscribed angles sharing that arc will be half the measure of the same central angle. Therefore, the inscribed angles must all be congruent.
