Answer:
If you want them at the same exact point then since the theif is 9 steps ahead it
will take 3 seconds
Step-by-step explanation:
Robber:
<em>starts at 9</em>
<em>starts at 9add on 5 and you get 14</em>
<em>starts at 9add on 5 and you get 14add 5 more you get 19</em>
<em>starts at 9add on 5 and you get 14add 5 more you get 19and another 5 would give you 24</em>
Police:
<em>is</em><em> </em><em>at</em><em> </em><em>0</em><em> </em><em>meters</em><em> </em>
<em>add</em><em> </em><em>8</em><em> </em><em>any</em><em> </em><em>you</em><em> </em><em>get</em><em> </em><em>8</em>
<em>add</em><em> </em><em>8</em><em> </em><em>more</em><em> </em><em>and</em><em> </em><em>you</em><em> </em><em>get</em><em> </em><em>1</em><em>6</em>
<em>and</em><em> </em><em>another</em><em> </em><em>8</em><em> </em><em>would</em><em> </em><em>get</em><em> </em><em>you</em><em> </em><em>to</em><em> </em><em>2</em><em>4</em>
7 because when you have two negative together they change to positive. I learned like this the -enemy of my -enemy is my +friend.
Answer:
338 students.
Step-by-step explanation:
First get the total number of votes.
22+8+18+52=100.
Then find the fraction of stay home which is number of votes for stay home over total number of votes =52/100.
Ans is 52/100 × 650 = 338 students.

Answer:
x ≈ {-2.80176, -0.339837}
Step-by-step explanation:
Write in terms of sine and cosine:
sec(x) -5tan(x) -3cos(x) = 0 . . . . . . given, subtract 3cos(x)
1/cos(x) -5sin(x)/cos(x) -3cos(x) = 0
Multiply by cos(x). (Note, cos(x) ≠ 0.)
1 -5sin(x) -3cos(x)² = 0
Use the trig identity to write in terms of sin(x).
1 -5sin(x) -3(1 -sin²(x)) = 0
3sin(x)² -5sin(x) -2 = 0 . . . . . . . . quadratic in sin(x)
(sin(x) -2)(3sin(x) +1) = 0 . . . . . . factor the quadratic
Values of sin(x) that make this true are ...
sin(x) = 2 . . . . . true only for complex values of x
sin(x) = -1/3
Then the possible values of x are ...
x = arcsin(-1/3), -π -arcsin(-1/3)
x ≈ {-2.80176, -0.339837} . . . . . rounded to 6 sf
