Answer:
Step-by-step explanation:
To find this equation in standard form, first, write it in factored form. This looks like . Then, multiply the polynomials using the FOIL (First, Outside, Inside, Last) method.
- Following the FOIL method, you should multiply the first terms in each binomial, , which equals .
- Then, the outside terms, . This equals .
- Next, the inside terms, .
- Finally, the last terms, , this equals .
Then, add all of the terms together . To get the standard form, combine like terms, this comes out to .
Answer:
Step-by-step explanation:
Given is a function
Since leading term is positive,
the parabola is open up.
Let us write this in vertex form after completing the square
Hence we get vertex= (-5/2,-1/4)
Since this is a parabola open up we have the minimum point is only one at x=-5/2
So we have the function decreasing for x<-2.5 and increasing for x>-2.5
Decreases in
Increases in
20% of 215,000......turn ur percent to a decimal...." of " means multiply
0.20(215,000) = 43,000
Answer:
1. Below 2. B. d = 8h
Step-by-step explanation:
The graph is a bit confusing. But basically, substitute x for the numbers they give you.
5x
5 · 1 = 5 = y
5 · 2 = 10 = y
5 · 3 = 15 = y
5 · 4 = 20 = y
7x
7 · 1 = 7 = y
7 · 2 = 14 = y
7 · 3 = 21 = y
7 · 4 = 28 = y
