Which expression is equivalent to x^6y^8/x²y²

Kipish [7]

Answer:

For this case we have the following expression:

(x ^ 6y ^ 8) ^ 3 / x ^ 2y ^ 2

Rewriting and for power properties we have:

(x ^ 18y ^ 24) / x ^ 2y ^ 2

(x ^ (18-2) y ^ (24-2))

(x ^ 16y ^ 22)

Answer:

At the start of 2014 lucys house was worth ?200 000. The value of the house increased by 5% every year. Workout the value of her

Galina-37 [17]

Answer:

The value of Lucys house at the start of 2017 is 231525.

Step-by-step explanation:

It is given that the initial value of Lucys house is 200,000. The at the start of 2017.

The exponential function is defined as

$P=P_0(1+r)^t$

Where, P₀ is initial value, r is growth rate, t is time in years.

The value of house is defined by the function

$P=200000(1+0.05)^t$

Where, t is number of years after 2014.

$P=200000(1.05)^t$

The difference between 2017 and 2014 is 3 years.

$P=200000(1.05)^3=231525$

Therefore the value of Lucys house at the start of 2017 is 231525.

Volume of cylinder = Base Area x Height

Height = Volume/Base

Height = (6n² -13n -28)/(3n+4)
Perform this division and you will get Height = 2n-7
