The answer is B because the domain is the x value, and because the lines have arrows they continue forever, meaning that they contain all real numbers.

A wildfire is spreading at an alarming rate. The wildfire begins at a size of 8 square feet. It then doubles its width every x h

Mrac [35]

Answer:

$14000=8\times 2^{x+y}$

Step-by-step explanation:

The wildfire begins at a size of 8 square feet

It means that initial area =8

It then doubles its width every x hours,

and doubles its length every y hours

so, we can set up equation

$A(x,y)=8(2)^x\times (2)^y$

now, we can simplify it

$A(x,y)=8(2)^{x+y}$

we are given

After a period of time, the wildfire covers 14,000 square feet

so, we can set A(x,y)=14000

we get

$14000=8(2)^{x+y}$

$14000=8\times 2^{x+y}$

Write the rule for this pattern 1, 2, 4, 7, 11

rusak2 [61]

I'm not sure how to write the rule, but every time you add one more to the sum of the last two. First, you add 1, then 2, then 3. 1+1=2 2+2=4 4+3=7 7+4=11 and so on. I hope this helps!
