Answer: The initial value of a function is its value when equals zero. This is the same as the -intercept. We can see from the graph that our line crosses the -axis at the point zero, eight. Therefore, the initial value is eight.

There are eight boxes. Each box holds one sweater. There are 3 blue, 2 brown, 1 green, and 2 red sweaters. What is the probabili
Reil [10]

3 + 2 + 1 + 2 = 8, which is the amount of sweaters.
The probability of a brown sweater is 2 / 8 = 0.25
And the probability of a green sweater is 1 / 8 = 0.125.

Multiply the two probabilities together to get the probability of choosing brown then green:
0.25 * 0.125 = 0.03125.

To convert a decimal to fraction, you multiply the numerator and denominator, or in this case \frac{0.03125}{1} by 1000 which gets \frac{31.25}{1000}

Which can be simplified to:
\frac{1}{32}.

Hope this helps.

Let the model for the change in water vapor be

y = x^3 − 8x^2 + 15x

to find the x intercepts we can factor this expression

x^3 − 8x^2 + 15x = x(x−3)(x−5)

the x intercepts are 0, 3, 5

Hope this helps!
