There are going to be two solutions because the "biggest" x is x^2 but you can factor to find what they actually are.
Answer:
y = 4 sin(t/2 + 4π/3) − 2
Step-by-step explanation:
General form:
y = a sin(2π/T t)
Given a = 4 and T = 4π:
y = 4 sin(2π/(4π) t)
y = 4 sin(t/2)
Add horizontal shift of -4π/3 and vertical shift of -2:
y = 4 sin(t/2 − (-4π/3)) − 2
y = 4 sin(t/2 + 4π/3) − 2
Answer:
<h2>x = 3</h2>
Step-by-step explanation:
Look at the picture.
Therefore we have:
<em>cross multiply</em>
<em>divide both sides by 3</em>
3*boys=2*18
3*boys=36
boys=12
12+18=30
total number of students: 30
