Answer:
the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.
The rate of melting is 1.5inches per hour. It will take 10 hours at the melting rate given of 1.5 to melt all the snow.
Step-by-step explanation:
the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.
The rate of melting is 1.5inches per hour.
At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start
At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.

<span>let the two number be x and y
x + y = 156
y = 156 - x
Product of the 2 numbers:
x(156 - x) = </span>
<span>
This maximum value occurs when x = -b / (2a). [This is a standard rule]
</span>
a = -1 and b = 156
x =
x = 78
y = 156 - 78 = 78
product = 78 x 78 = <span>6084 </span>
So the two positive numbers are 78 and 78.
