An=a1+d(n-1)
a1=first term
an=nth term
d=common differnce or how much it increases by each time
n=which one


so
originally 3 trees
a1=3

and after 19 years, 84 trees, so a19=84

a19=84=3+d(19-1)
84=3+d(18)
minus 3 both sides
81=18d
divide both sides by 18
4.5=d


an=3+4.5(n-1) or
an=4.5n-1.5
or
t(n)=3+4.5(n-1) or
t(n)=4.5n-1.5

Help need this answer as as possible
SashulF [63]

Answer:

15.5

Step-by-step explanation:

I can help with this. He doesn't tell how many dollars she earned from her dad but tells you what is left. So we add 13.73 + 1.77

We add because She used to spend it and because she only gave us what was left. We want to push it to what it was before so we do the opposite.

13.73 + 1.77 = 15.5

I am not really sure of what the words are on the last part but i think u can figure it out. My answer is 15.5 but if you aren't asking for this just ignore it.

Rewrite the function in standard form, intercept form, find the vertex, find the y-intercept, and find the x-intercepts.
jasenka [17]

Answer:

We have the function, f(x)=(x+3)^{2}-4

On simplifying, we get,

f(x)=x^2+6x+9-4

i.e. f(x)=x^2+6x+5

Thus, the standard form of the function is f(x)=x^2+6x+5.

Now, the factors of the given functions are (x+1) and (x+5).

<em>Since, the intercept form of the function is the factored form of the function.</em>

So, we have, intercept form of the function is f(x)=(x+1)(x+5).

Now, we know that,

Value of x-coordinate of the vertex is \frac{-b}{2a} i.e. \frac{-6}{2\times 1} i.e. \frac{-6}{2} i.e. x= -3

Then, f(-3)=(-3)^2+6\times (-3)+5 i.e. f(-3)=9-18+5 i.e. f(-3)=-4

So, the vertex of the function is (-3,-4).

Further, we know that,<em> 'the y-intercept of a function is the point where the function crosses y-axis'.</em>

So, when x=0, we have, f(0)=0^2+6\times 0+5 i.e. f(0) = 5

Thus, the y-intercept is (0,5)

Also, <em>'the x-intercept of a function is the point where the function crossese x-axis'.</em>

Then, for f(x)=0, we have 0=x^2+6x+5 i.e. 0=(x+1)(x+5) i.e. x= -1 and x= -5

Thus, the x-intercept are (-1,0) and (-5,0).
