A forest fire covers twice the amount of forest as it did 3 days ago. If the fire covered 300 square miles 3 days ago and it con
OLEGan [10]
This would depend on if we assume this is constant or exponential growth.  If it is linear then it would be:

600=3m+300

300=3m

100=m

A=100d+300

A(12)=1500 mi^2

If it is exponential:

600=300r^3

2=r^3

r=2^(1/3)

A=300(2)^(d/3)

A(12)=4800 mi^2

Find the zeros from the factored form Quadratic Equation y=-x(x-3) ( ,0) &amp; ( ,0)​
tangare [24]

Answer:

(0, 0) and (3, 0)

Step-by-step explanation:

Zeros of any equation means, value of variable x at y = 0.

Given quadratic equation is,

y = -x(x - 3)

For y = 0,

-x(x - 3) = 0

x = 0

And (x - 3) = 0

x = 3

Therefore, x-intercepts of the given quadratic equation will be,

x = 0, 3

Points showing the x-intercepts will be,

(0, 0) and (3, 0)
