The height of a tree in feet over x years is modeled by the function f(x).

SVEN [57.7K]

The following statements are true:
The tree grows approximately 7 feet between years 5 and 7;
the tree stops growing at around 30 feet

In graphing the function, we see that the initial value, when x = 0, is 1 ft, not 2.
Additionally, we can see the values as the height increases; when the tree hits 15 feet, it continues to grow at around 1.5 feet every 0.4 years until it hits around 25 feet tall. Then it begins to slow down.

Answer:

The function will be: f(n) = 2n

Step-by-step explanation:

An arithmetic sequence is a sequence where the common difference between consecutive terms is same

The sequence according to given information is:

2,4,6...

Here

a_1 = 2

a_2 = 4

a_3 = 6

the common difference will be:

$d = a_2-a_1 = 4-2 = 2\\d = a_3-a_2 = 6-4 = 2$

The arithmetic sequence is given by:

$a_n = a_1+(n-1)d$

Putting the values

$a_n = 2+(n-1)(2)\\a_n = 2+2n-2\\a_n = 2n$

Hence,

The function will be: f(n) = 2n

Whats the order pair of x,y for x-2y=-12 x 6y=20?

mote1985 [20]

X-2y=-12
x+6y=20
we can cancel x's
multiply first equation by -1 and add to 2nd equation

-x+2y=12
<u>x+6y=20 +</u>
0x+8y=32

8y=32
divide both sides by 8
y=4

sub back

x-2y=-12
x-2(4)=-12
x-8=-12
add 12 both sides
x=-4

(x,y)
(-4,4)
