Answer:

Option A, 1/6² is not equivalent to the expression

Step-by-step explanation:

Lets simplify the given expression first:

\frac{6^3}{6^6} = \frac{216}{46656} which simplifies to; \frac{1}{216}

Now let's see why the first equation is not equal to the simplified expression:

  • Option A, \frac{1}{6^2} simplifies to \frac{1}{36}, this <u>is </u><u>not</u><u> equal</u> to the given expression
  • Option B, Since there is a negative exponent, to make this to a positive exponent, we take the opposite reciprocal of the expression, which equals to \frac{1}{6^3}, which simplifies to \frac{1}{216} which <u>is equal to</u> the expression above
  • Option C, this is already the simplified form of the equation, thus <u>it's equal to</u> the expression given.
  • Option D, we already know that \frac{1}{6^3} simplifies to \frac{1}{216}, therefore <u>it's equal.</u>

As noticed all the expressions are congruent to the given expression BUT expression given in the first option, therefore they are not equal.

Hope this helps!

Naddika [18.5K]
To find the inverse of the function you can just exchange the name of the variables, change x for y and y for x..

original (direct) function: y = x^2 - 7

inverse function x = y^2 - 7

Then, the answer is the option c.

(8) We pour water into a pool. Suppose that w = The amount of water in the pool (in gallons) at time t(in minutes) Given the fol
Mila [183]

Answer:

Step-by-step explanation:

The average rate is just the slope of the function between t = 0 and t = 10, so we must calculate change in w / change in t. w(10) = 130. w(0) = 100. So, the slope = (130-100)/(10-0) = 30/10 = 3 gallons per minute.

The price of a notebook in 2012 is $2000. In 2013, its value decreased by 30%. In 2014, its value decreased by 30% of its value
jeyben [28]

Answer:

The value of the notebook at the end of 2013 is $980

Step-by-step explanation:

First, find 30% of 2,000. To do so you need to convert 30% into a decimal by dividing it by 100.

30% ⇒ 0.30

Now multiply 0.30 by 2,000 to find 30% of 2,000.

2,000 × 0.30 = 600

Subtract 600 from 2,000 to find the price of the notebook in 2013.

2,000 - 600 = 1,400

Now find 30% of 1,400 using the same process.

1,400 × 0.30 = 420

Subtract 420 from 1,400 to find the price of the notebook in 2014.

1,400 - 420 = 980
