Place the correct coefficients x²y³ + in the difference. xy² + y

antiseptic1488 [7]

The difference between the two polynomials is 11x²3y³ - 4xy².

<h3>What is the Difference between the Polynomials?</h3>

The difference between two polynomials is the result you get by subtracting one from the other.

Thus:

= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)

= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y

= 11x²3y³ - 4xy²

Which function is undefined when theta=pi/2 radians?

Verizon [17]

We know that tanθ = sinθ/cosθ

For a number to be undefined, the denominator must equal to 0. At π/2, the cosθ value is 0 and sinθ is 1. Hence, tan(π/2) is undefined.

Hope I helped :)

patty bought a shirt for $14.50 plus9% tax. ales bought a sweater for $22.95 plus 9% write the sum in dollars that patty and ale

siniylev [52]

Answer: The amount that patty and ales paid including taxes was $40.96.

Step-by-step explanation:

To calculate the cost of the shirt and sweater together, we first calculate the total cost of shirt and sweater individually.

Amount paid by Patty:

Shirt of $14.50 + 9% tax

Tax paid = $9\%=\frac{9}{100}=0.09$

Amount of tax paid = ($14.50 × 0.09) = $1.305

Amount paid by patty = $14.50 + $1.305 = $15.805

Amount paid by Ales:

Sweater of $22.95 + 9% tax

Tax paid = $9\%=\frac{9}{100}=0.09$

Amount of tax paid = ($22.95 × 0.09) = $2.0655

Amount paid by ales = $22.95 + $2.0655 = $25.0155

Total amount paid by both Patty and ales = $15.805 + $25.0155 = $40.96

Hence, the amount that patty and ales paid including taxes was $40.96.
