Megamart collects a sales tax equal to 1/16 of the retail price of each purchase. is the amount proportional to the cost of an item before tax is added. explain retail price. |16 | 32 | 48 | 64| tax collected |. |. |. |. |

1,2,3 and 4

Step-by-step explanation:

Here we are given that the tax applied is of the retail price at which the item is sold. Hence in order to find the tax collection , we have to find the product of price of the item with .

Let us evaluate the tax collected on each item with different prices.

a) Price = 16

Tax =

Hence Tax = 1

b) Price = 32

Tax =

Hence Tax = 2

c) Price = 48

Tax =

Hence Tax = 3

d) Price = 64

Tax =  

Hence Tax = 4

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
