Number of toothpicks = (number of students) x (toothpicks)
(C) cause 17•3=51+39= 90 and that’s a 90 degree
Recall that 2sin(x) cos(x) is actually equal to sin(2x).
We can prove this by expanding sin(2x) to sin(x + x).
sin(x + x) = sin(x) cos(x) + cos(x) sin(x) = 2sinxcosx
Thus, 2sin(x/2)cos(x/2) can be rewritten in the form:
sin(2x/2), and this simplifies down to sinx.
Answer:
$1800
Step-by-step explanation:
12000(1+0.05x 3)
= 13800
13800 - 12000
$1800
