Raj fully simplified the polynomial and then put it in standard form with the last term being 6y3. 2x2y + 8x3 – xy2 – 2x3 + 3xy2

JulijaS [17]

Original polynomial:

2x^2 y + 8x^3 - xy^2 - 2x^3 + 3xy^2 + 6y^3

Order the polynomial in ascending order of y

8x^3 - 2x^3 + 2x^2y + 3xy^2 - xy^2 + 6y^3

Add up the similar terms:

6x^3 + 2x^2y + 2xy^2 + 6y^3

Thats is the polynomial Raj ended up with.

And the first term is 6x^3.

Answer: 6x^3

The data set below provides the monthly rent (in dollars) paid by 5 tenants. 879 , 920 , 940 , 950 , 990 Suppose the rent for on

MrRa [10]

Answer:

Mean before the rent changes = $935.8

Mean after the rent changes = $970.8

Step-by-step explanation:

Mean = sum of all data values / number of data values in a given data set

✔️Data set consisting of the rents of 5 tenants: 879 , 920 , 940 , 950 , 990

Mean before the rent changes = (879 + 920 + 940 + 950 + 990)/5 = 4,679/5 = 935.8

Mean before the rent changes = $935.8

✔️If one of the tenants rent changes from $940 to $1,115, the new data set would be:

879 , 920 , 1,115 , 950 , 990

Mean after the rent changes = (879 + 920 + 1,115 + 950 + 990)/5 = 4,854/5 = 970.8

Mean after the rent changes = $970.8

A bicycle has a listed price of $619.98 before tax. If the sales tax rate is 7.5% , find the total cost of the bicycle with sale

Julli [10]

Hey there.

We can calculate the total cost by multiplying the price before tax by the decimal form of the sales tax.
This translates to:

619.98 · 0.075 = 46.50 (rounded)

Now we add the listed price and the tax.

619.98 + 46.50 = 666.48

The total cost the bicycle is $666.48
