<p>@isk8jen Pre-calculus. It’s possible to get a 36 with just Pre-cal since the highest math the ACT includes is trigonometry.</p>

102

<p>@isk8jen - just do as many practice tests in Math as you can. The math should be similar - the hard problems vary the most, but the best way to score highly in Math is to do a lot of practice tests. You can find several for free online (2 alone on the ACT website).</p>

103

<p>I also got sec x tan^2 x. Someone care to explain?</p>

104

<p>what was the answer to the one with a triangle and a line. with 4y and 11y and then 42 was the angle inside? please help!</p>

105

<p>I got 89 for that one ^</p>

106

<p>I also got 89.</p>

107

<p>What about the girl running at +4km? Positive slope?</p>

108

<p>That’s what I got. ^
since it was traveled distance vs. time</p>

109

<p>@jkim this is the trig identity question solved:</p>

<p>Are you 100% positive that was the question? I thought the tanx was multiplied, not divided??</p>

111

<p>It is for sure secx</p>

112

<p>^ Yeah, the tanx was in the denominator.</p>

113

<p>Do you guys remember what answer choice (A, B, C, D, E or F,G…) secx was?</p>

114

<p>Definitely sec x</p>

<p>@master: I can’t remember the answer choice</p>

115

<p>@ephemeralbliss aww man I forget if I put positive slope or circle. If I put circle I feel like such an idiot now haha. I guess what might have thrown me off is the queston saying she started and finished at home. Are we sure it said TOTAL distance (y-axis) vs time (x-axis)?</p>

116

<p>sec x was second to last one.</p>

117

<p>what were the answers for the questions with the animals?</p>

118

<p>@omaha7878
105/225
70%? where it asked for whole percentage of those who owned only one type of pet
the first question asked about the estimated value of those who owned ___ as a whole population…
and i forget the rest.</p>

119

<p>@Jim I got 70% for that question as well</p>

120

<p>ugh it asked for perecent not number?</p>
