p=15250
r=7.5/100=0.075
y = 15250*(1 - 0.075)^x
after 8 years it would be
x = 8
y = 15250*(1 - 0.075)^8
y = $8,173.42
after 8 years the value of the car is going to be $8,173.42
Answer:
equation y =7/4x+1
slope = 7/4
Step-by-step explanation:
We have two points so we can find the slope
m =(y2-y1)/ (x2-x1)
= (4--3)/(2--2)
= (4+3) / (2+2)
= 7/4
We know the slope and the y intercept
We can write the equation using y = mx+b where m is the slope and b is the y intercept
y= 7/4x +1
We put at dot at (0,1) and then go up 7 and to the right 4 . We put another dot
Connect the dots and we have our line.
We could also put dots at (-2,-3) and (2,4) and connect the dots.
For this case what you should know is that by definition the volume of the cone is given by:
V = ((pi) * (r ^ 2) * (h)) / (3)
Remembering that:
r = d / 2
Substituting the values:
V = ((pi) * ((d / 2) ^ 2) * (h)) / (3)
V = ((pi) * (((10) / 2) ^ 2) * (12)) / (3)
V = 314.16 ft ^ 3
Answer:
V = 314.16 ft ^ 3
The nearest option is:
300 cu. ft
