a yard is equal in lenght to three feet. The function f(x) takes a measurement in yards (as input) and returns a measurement in
feet (as output)
1 answer:
The value of is B. 46.2.
Step-by-step explanation:
Step 1:
f(x) is dependent on the value of x.
So x is independent while f(x) is dependent on x i.e. the value of f(x) depends on the value of x.
Step 2:
So if we have the value of x we can calculate the value of f(x). Here the value of x is given as 15.4 so f(x) when x equals 15.4 can be calculated.
So the value of f(15.4) is 46.2 which is option B.

Options:
a. Nikki's proposed placement will light a greater area than Dylan's placement.
b. Dylan's proposed placement will light a greater area than Nikki's placement.
c. Both proposed placements will light the same sized area.
d. Nikki's proposed placement will light more than half the yard.
e. Dylan's proposed placement will light more than half the yard.
f. Dylan's proposed placement will light exactly half of the yard.
g. Nikki's proposed placement will light less than half of the yard.
Answer:
C) Both proposed placements will light the same sized area.
F) Dylan's proposed placement will light exactly half of the yard.
Step-by-step explanation:
The area of a triangle is (base x height) / 2, and both lights illuminate the same base and height = (60 x 38) / 2 = 1,140 sq ft
Both Dylan's and Nikki's proposed placement will lit exactly half of the yard. The yard's total area = 60 x 38 = 2,280 sq ft, which is twice the area lit by the lights.
