Answer:
none of the above
Step-by-step explanation:
0.89 times 18 = $16.02
An inequality that represents his purchase is 0.85x + 1.29y < 5. The sign is less than, because you spend less than that, not equal to that.
Answer:
The inverse function is 3x+2
Step-by-step explanation:
To get the inverse function exchange x and y and then solve for y
y = (x-2)/3
Exchange x and y
x = (y-2)/3
Solve for y
Multiply by 3
3x = 3/3 *(y-2)
3x = y-2
Add 2 to each side
3x+2 = y-2+2
3x+2 =y
The inverse function is 3x+2
To make it easier, aprox pi=3.14
area=pir^2
36=area
36=pir^2
divide both sides by pi
36/pi=r^2
36/3.14=r^2
11.464=r^2
square root both sides
3.39=r
circumfernce=2pir
r=3.39
circumfrence=2pi times 3.39
circumference=pi times 6.78
circumference=3.14 times 6.78
circumfernce=21.29
answer is
circumference=21.29 in
