Oh goodness

I hope to be posting soon, but summer hw that I procrastinated are getting in the way 😦 in the meantime, enjoy my posts apologizing that I’m not posting very much! Every single day!

And the time is .

Man it’s late again.

I’m working a little on inequalities these days, but today I got bored waiting for the bus so I started doing a few. But I’m an idiot and the bus passed me. I guess it didn’t see me on the ground 😦

And the time is .

Solutions to the SAT thing

16. Which of the following is a zero of ?

(A) 
(B) 
(C) 
(D) 
(E) 

22. What is the length of the major axis of the ellipse given by the equation ?

(A) 
(B) 
(C) 
(D) 
(E) 

Solution (mine):

16. Solving using the quadratic formula, we get:


Plugging this into the calculator and rounding to the hundredth’s place, we get that . The only answer choice that equals one of these values is (B) .

22. The major axis is the longest “diameter” in an ellipse:

major-minor-axis

The ellipse described would have a width of and a height of . Since the longer length is , the answer is (C) .

Conclusion

So I missed these problems because I’m careless and because I didn’t know how to multiply by two for the major axis. Pretty good, I guess!
