Aschool club is raising money for a trip, and needs to reach $10,000. their fundraising progress is modeled by the function f(x) = 435 + 1200x, where x is measured in weeks. what is the meaning of the constant 435? a) it is the amount they started with. b) it is the amount still to be raised. c) it is the amount which is left over. d) it is the amount they raise each week.

Step-by-step explanation:

435 refers to the amount they started with because the independent term of a linear equation refers to the initial condition of the problem that models. Also, 435 is not related with the variable, which means that it won't variate. So, if cannot be the weekly money, then it's the initial money.

In addition, the term 1200x expresses that they raise $1200 per week, because x refers to weeks.

Therefore, the answer is A.

$27.5

step-by-step explanation:

$110.00 divided by 4

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
