100 cm
1 m is equivalent to 100cm
Y=2(x+3)^2+2
y=2(x^2+6x+9)+2
y=2x^2+12x+20
dy/dx=4x+12
The graph is decreasing when dy/dx, which is velocity, is less than zero so:
dy/dx<0 when:
4x+12<0
4x<-12
x<-3
So the graph is decreasing from x=(-oo, -3)
Answer:
$4.48
Step-by-step explanation:
First, you have to convert the percentage into a decimal.
12% x 100 = 0.12
Second, you multiply the decimal with the cost of the product before tax.
$4 x 0.12 = $0.48
This number is the amount of money you will have to pay in tax.
Third, you add the tax amount to the original cost of the product to get the total price.
$4 + $0.48 = $4.48
7.95*0.06 to get amount of tax you're paying
$0.477is how much tax you're paying. (round it up to 0.48)
7.95-0.48
$7.47
The answer is $7.47
