F(t)=30 sin(pi/3 t)-15
when sin(pi/3 t) = 1, f(t) = 15 => max.
when sin(pi/3 t) = -1 f(t) = -45 .+ min.
period = 2π / (π/3) = 6 hrs.
<h2>
Thus, the required "option 4)" is correct.</h2>
Step-by-step explanation:
We find,
To find, the binomial expansion of of = ?
We know that,
∴
Here, n = 7, x = x and y = 2y
=
∴ The binomial expansion of of
Thus, the required "option 4)" is correct.
Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
<h3>Answer is choice A</h3>
JCL because
JCL + LCT = 90
If you notice there is a right angle symbol
Answer:
25 cupcakes
Step-by-step explanation:
set up a proportion then cross-multiply:
3/15 = 5/c
3c = 75
c = 25
