Step-by-step explanation:
To find AC we use tan
tan ∅ = opposite / adjacent
From the question
15 is the opposite
AC is the adjacent
tan 55 = 15 / AC
AC = 15 / tan 55
AC = 10.503
<h3>AC is 11 to the nearest tenth </h3>
Hope this helps you
Answer:
a) The portfolio will be at maximum after 12 months (1 year)
b) The maximum value of the portfolio is $5432
Step-by-step explanation:
The function that models Jennifer's stock portfolio (in dollars) is , where t is the time in months since she opened the account.
We complete the square to obtain this function in vertex form:
Factor -3 from the first two terms
.
Add the zero pairs -3(+144),-3(-144)
.
Factor the perfect square trinomial and simplify.
.
The vertex of this function is (h,k)=(12,5432)
a) The portfolio will be at maximum when t=12, the h-value of the vertex
b) The maximum value of the portfolio is the k-value of the vertex which is 5432
1/2 x 5/8 = 20/8 = 5/2
3/5 x 5/8 = 600/40 = 15
3/8 x 2/5 = 240/40 = 6
Answer:
All Real x (x not = 9).
Step-by-step explanation:
When x = 9, f(x) = 9/0 which is undefined.
So the Domain is All Real x, x not = 9.
