A fundraising organization will donate $250 plus half of the money it raises from a charity event. What is the independent Variable?

What is the dependent Variable?

What is the domain?

What is the range?

Independent Variable, Domain = Charity amount

Dependent Variable, Range = Donation amount

Step-by-step explanation:

Independent Variable is the causal variable. Dependent variable is the resultant or effected variable.

In this case, organisation donates money, a constant value (250) & a proportion (half) of charity. So, independent variable (causal) is charity, effecting the dependent variable ie donation.

Equation : Let donation = d, charity = c. Given : d = f (c) , where d = 250 + c/2

Domain is set of of all values for which a function is defined, range is the set of all values that f takes. So, domain is independent variable - charity & range is dependent variable - donation.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
