Answer:
- 7227
- 6649
Step-by-step explanation:
Let x represent the enrollment the first year. Then x(1 -8%) = 0.92x represents the enrollment the second year. The total for the two years is ...
x + 0.92x = 13,876
x = 13,876/1.92 = 7227.083 ≈ 7227 . . . . students the first year
13876 -7227 = 6649 . . . . students the second year
Answer:
denise,
Step-by-step explanation:
that is the only one i think
Try doing (0,-2) for the y intercept
Cos
θ
=
√
5
3
or it could be cos
θ
=
√
5
−
3
Explanation:
Since sin
θ
is negative, it can be in the third or fourth quadrant
Drawing your right-angled triangle, place your
θ
in one of three corners. Your longest side will be 3 and the side opposite the
θ
will be -2. Finally, using Pythagoras theorem, your last side should be
√
5
Now, if your triangle was in the third quadrant, you would have
cos
θ
=
√
5
−
3
since cosine is negative in the third quadrant
But if your triangle was in the fourth quadrant, you would have
cos
θ
=
√
5
3
since cosine is positive in the fourth quadrant
