Answer:
Only option C is correct, i.e. The input, or independent variable, is years in operation.
Step-by-step explanation:
Given is the scatter plot of Years in Operation vs. Enrollment at Daycare Center.
The input is always independent variable and is plotted along x-axis.
The output is always dependent variable and is plotted along y-axis.
From the graph, it is clearly visible that:-
x-axis: Years in Operation.
y-axis: Enrollment at Daycare Center.
It means <u>"The input, or independent variable, is years in operation."</u>
Hence, only option C is correct, i.e. The input, or independent variable, is years in operation.
Answer:
Step-by-step explanation:
take two points to find the equation:
(0,4),(-2,0)
y= 2x+4
domain is where the equation is defined ( x inputs)
Range is the set of values that correspond with the domain(y outputs)
the domain and the range are all real number
domain(-∞,∞) , range (-∞,∞)
Answer:
w≅8.46ft
Step-by-step explanation:
Data
focus=8
vertex=(0,0)
width=?
depth (y)=3ft
parabola equation: 
; then for V=(0,0), 
, be focus(f)=8in; 
→ 
we have that y=3ft then 
; but 1in≅0.083ft so 
→ x=±2.82, finally w=3*2.82≅8.46ft
