Ok. I am stealing questions off the sample exam.....
√ 2 × √ 15 = ?
A. 17
B. 30
C. √ 30
D. √ 17
That would be C, right? If not, why? (I just found the test key, and it is C....But I'm not sure why. At least my stab in the dark was right.)
The quadratic formula makes me want to drink heavily and spend the evening weeping under my dining room table.
What is the value of the expression 2x2 + 3xy – 4y2 when x = 2 and y = - 4?
A. -80
B. 80
C. -32
D. 32
What the hell....The "figure" is a circle with a smaller circle in the middle, the shaded area being a donut of sorts.
In the figure below, both circles have the same center, and the radius of the larger circle is R. If the radius of the smaller circle is 3 units less than R, which of the following represents the area of the shaded region?
A. πR2
B. π(R – 3)2
C. πR2 – π × 32
D. πR2 – π(R - 3)2
Because pi R squared is how you find the radius of a circle, right? So, it's D. No? Wait.
(3x – 2y)2 =
A. 9x2 – 4y2
B. 9x2 + 4y2
C. 9x2 + 4y2 – 6xy
D. 9x2 + 4y2 – 12xy
This is A, right? The 'squared' bits aren't coming through....that's supposed to be squared, not multiplied by two.
Which of the following expressions is equivalent
to 20 – 45 x > 16?
A. x ≤ 5
B. x ≥ 5
C. x ≥ 32½
D. x ≤ 32½
this one doesn't make a lick of sense to me.
If f(x) = 2x + 1 and g(x) = x – 12 , then f(g(x)) =
A. x
B. x – 14x + 2
C. 4x + 2x – 1
D. 5x + 12
E. (2x + 1)(x – 1)2
If θ is an acute angle and sin θ = 12, then cos θ =
A. -1
B. 0
C. 12
D. √32
E. 2
If log10x = 3, then x =
A. 310
B. 1,000
C. 30
D. 103
E. 310
If 3x2 – 2x + 7 = 0, then (x – 13)2=
A. 209
B. 79
C. -79
D. -89
E. -209
There are only 17 questions on the placement exam. To my knowledge, I cannot take it again. (I think I can take it again in 6 months, but never more than twice a year.) I don't believe that they can keep me out of college if I fail this--because they have to have a math class for morons, right? I mean, they make money from my being there, smart or not.....I'm just so terrified of failing. I failed college before (I did it to myself, mind. Drugs are bad, kids! So is crazy!) and I am so terrified of doing it again.
I am so embarrassed to have to show them my transcripts from my old university. I am so scared that they are going to look at my depressing and really really bad GPA and judge me. Think I am stupid.
I found my blog from when I was 20-21. I was reading over it, and it threw me into a huge depression....How flippant I was! How dumb! How I took everything for total granted, how all I cared about was sex and parties and drugs and music and some more sex (and more drugs, if you'd be so kind). I cringed, reading it. Literally.
What the fuck was I thinking? T says everyone has to 'find themselves' when they are that age....but unless I was hiding in the bottom of a bottle, in a bag of dope or in a strip club, I wasn't looking too damn hard.
But I guess if that stuff hadn't happened, I wouldn't be here now, and here ain't too bad.
But if it hadn't happened, I wouldn't be freaking out about how you multiply fucking fractions either.
