Question

cai had 3 inches of snow on his lawn. it then began to snow at a rate of 2.5 inches per hour. assume no snow melted. answer the questions below regarding the relationship between the number of hours since snow began falling and the total amount of snow on cais lawn. answer attempt 1 out of 2 the independent variable, x, represents the , and the dependent variable is the , because the depends on the . a function relating these variables is k(x)=. so k(10)=, meaning after 10

Explanation:

Step1: Identify variables

Independent: number of hours; Dependent: total snow amount as it depends on hours.

Step2: Form function

$K(x)=3 + 2.5x$

Step3: Calculate $K(10)$

$K(10)=3+2.5\times10=28$

Answer:

The independent variable, $x$, represents the number of hours since snow began falling, and the dependent variable is the total amount of snow on Cai's lawn, because the total amount of snow depends on the number of hours.
A function relating these variables is $K(x)=3 + 2.5x$.
So $K(10)=28$, meaning after 10 hours there are 28 inches of snow.
