She used 180 beads because 45x4 =180
Answer:
<em>y = 1 + 2x</em>
<em>or</em>
<em>y = 2x + 1</em>
Step-by-step explanation:
I hope this helps!
Let <em>"x"</em> represent the chicken's age.
<em>"Y</em> "demonstrates the ounces.
Recall the double angle identity,
sin(2x) = 2 sin(x) cos(x)
Then we can write
sin(9x) cos(9x) = 1/2 sin(2 • 9x) = 1/2 sin(18x)
Then
∫ sin(9x) cos(9x) dx
= 1/2 ∫ sin(18x) dx
= -1/2 • 1/18 cos(18x) + C
= -1/36 cos(18x) + C
though you could continue with another double angle identity,
cos(2x) = cos²(x) - sin²(x)
to rewrite the antiderivative as
= -1/36 (cos²(9x) - sin²(9x)) + C
= 1/36 (sin²(9x) - cos²(9x)) + C
Answer:
200 units.
10 minutes.
Step-by-step explanation:
Distance = 100 - (-100)
= 100 + 100
= 200 units.
Speed = distance / time
20 = 200/ t
t = 200/20
= 10 minutes.
