Step-by-step explanation:
Given that,
v(t) = A + B•sin(ωt)
Then,
When t = 0 v(t)= 7
7 = A + B•Sin(ω×0)
7 = A + B•Sin0
7 = A
Then,
A = 7
v = 7 + B•sin(ωt)
So,
When t = 3, v(t) = 9
v = A + B•sin(ωt)
9 = 7 + B•Sin(3w)
9-7 = B•sin(3ω)
B•sin(3w) = 2. Equation 1
Also, at t = 6 v(t) = 7, at this point, when it returns back to7, it has complete one oscillation
v = A + B•sin(ωt)
7 = 7 + B•Sin(6w)
7-7 = B•sin(6ω)
B•sin(6w) = 0
Sin(6w) = 0 / B
Sin(6w) = 0
Take arcsin of both sides
6w = Sin~1(0)
6w = π, since it has complete one oscillation
Then, w = π /6
w = π/6
Then,
v(t) = 7 + B•Sin(πt/6)
From equation 1
B•sin(3w) = 2.
B•Sin(3 × π/6) = 2
B•Sin(½π) = 2
B = 2
Then,
v(t) = A + B•sin(ωt)
A = 7, B = 2 and w = π/6
v(t) = 7 + 2•sin(πt/6)
Answer:
$12.95 is the final cost for the oranges
$12 is the cost for apple
Step-by-step explanation:
The final cost for the orange is
30/100 x 18.50
=5.55
18.50-5.55
=$12.95
For this case we must find the value of "x" of the following equation:
So:
We add 9 to both sides of the equation:
We apply square root on both sides of the equation to eliminate the exponent on the left side:
Thus, the solutions are:

Answer:
B) x^2y + 7
Step-by-step explanation:
we are given
We can use grouping method to factor it
now, we can factor common terms
so, we get
we can see that x^2y+7 is one of factor
