Answer:
The following would be best modeled by an exponential decay function
A.) An island is being eroded away and loses 10% of its beachfront every year.
D.) A machine depreciates (loses value) by $1000 in its first year, by $2000 in its second, $3000 in its third, etc.

To find the x intercept,plug a zero in for y and solve.
To find the y intercept,plug a zero in for x and solve.
y = 7x + 3
g = 7(0)+3
y = 3
(0,3)
y = 7x + 3
0 = 7x + 3
Subtract 3 from both sides.
-3 = 7x
Divide both sides by 7
-3/7 = x
(-3/7, 0)
Answer:
x =3
Step-by-step explanation:
The axis of symmetry is at the vertex
The x coordinate gives the axis of symmetry
x =3
Answer:
it is 6 days
Step-by-step explanation:
For the first one to find the total area you have to first find the area of the triangle 1/2(10x12.5)=62.5 and then the square (13.4x12.5)=167.5 which is 10468.75 totaled
