Answer:
A. y = 3x; 30 feet
Step-by-step explanation:
The person travels 75 feet in 25 seconds, meaning that he will travel 3 feet per second.
75/25 = 3
This means that the equation will be y = 3x. To find the the feet traveled after 10 seconds, plug 10 into the given equation and solve for y.
y = 3x
y = 3(10)
y = 30
The person will travel 30 feet.
Answer:
greater
Step-by-step explanation:
function b: y= 2x - 5
You have to find the surface area of the shapes, then add them all together. Then divide the SA to the 0.5 m² can of grey paint.
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
