His dog ate 1/2 of his collection, this means that there are only 33 left. If I multiply 33x2, I will get 66. Therefore, Fred started with 66 cards.
(If you’re not counting the cards he purchased, then Fred would have 59 cards.)
what's the question? you only put a formula
The inverse function of cos is arccos (cos^-1(x)). So, the only one that has arccos(x/6) is option c. That's your answer!
Answer:
Step-by-step explanation:
F(x)=x³-27/x²-9
F(x)=(-9)³-27/(-9)²-9
F(x)=-729-27/-81-9
F(x)=-756/-90
F(x)=42/5
