Official ACT June 11th thread

<p>sin(kx) hits the axis k times so 2sin(kx) will hit the axis the same number of times. The two only affects the amplitude in the vertical direction; it doesn't change how many times the fuction hits the x-axis</p>

<p>hey no one answered this one
was it patient's needs or patients needs or what was it</p>

<p>patients' needs</p>

<p>I put patient's needs</p>

<p>edit: gah</p>

<p>i think i did too...i know i debated between 2 answers for awhile but i think i put patient's needs.</p>

<p>dang, i put it into my calc as 2 sin 2x and forgot that if it was 2sinx origianlly it woulda been 2k originally so the answer woulda been k.</p>

<p>the answer was 24,300. so you're right!</p>

<p>I'm pretty sure it should have been the plural form</p>

<p>n= -n</p>

<h2>it makes the most sense. Look at Shahein's explanation.</h2>

<p>Ugh! It wasn't patient's?</p>

<p>what was the answer (the letter) to the last question in science?</p>

<p>I agree, I think I put that, I just remembered the probken wrong</p>

<p>It depends on the sentence... I can't remember if it was used as a singular or plural noun</p>

<p>that monkey question was so confusing</p>

<p>x was greater than or equal to 0 and less than 2pi for the interval.</p>

<p>ok when you graph y = sin x there are two spots from x = 0 to x less than 2pi where it crossed the x-axis. then for y = sin 2x there are four crossings. that means 2k is the right answer?</p>

<p>45 rev 360*
------- X 1.5 min X ------ = 24,300. Correct?
1 min 1 rev</p>

<p>I agree with TSA; it was 24,300.</p>

<p>and at what day would theta (in the einstein passage) be greatest? 150, 300, 450, 600 days?</p>

<p>i think i said 300 but i dont remember</p>

<p>Oops, didn't come out right. (45 rev/min) x (1.5 min) x (360*/ rev) = 24,300. Can anyone verify that?</p>

<p>the two was in front of the sin(x), not inside the argument</p>
