Rates are used to show how a quantity measures over another.

Andy does not read at a constant rate.

The table is given as:

\left[\begin{array}{cccccc}x&10&20&30&40&50\\y&4&9&10&15&20\end{array}\right]

Pick any two points from the table:

(x_1,y_1) = (10,4)

(x_2,y_2) = (20,9)

The rate (m) is then calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

So, we have:

m = \frac{9-4}{20-10}

m = \frac{5}{10}

m = 0.5

Pick another point from the table

(x_1,y_1) = (10,4)

(x_2,y_2) = (30,10)

The rate (m) is then calculated as:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{10 - 4}{30 - 10}

m = \frac{6}{20}

m = 0.3

The rates calculated are not equal

<em>i.e. 0.3 and 0.5 are not equal</em>

This means that;

Andy does not read at a constant rate.

If the surface area of the box of cereal is 272 inches squared, find the length of the box.
LekaFEV [45]

Answer:

x= 8 inches

Step-by-step explanation:

you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-

dimensions of the box:

12 in x 2 in x ?

=272 square inches

and we know that there are 6 faces

area=  2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)

area = 272 sq. in.  = 48 + 4x + 24x

272 = 48 + 28x

272 - 48 = 28x

224 = 28x

x = 8 inches

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Which of the following is written as a rational function? a. G(x)=-4x b. P(x)=7x 1 c. F(x)=x-5/3x d. Q(x)=x^2 6x-3.
slavikrds [6]

The function can be expressed as a rational function is \rm\dfrac{x-5}{3x}.

We have to determine

Which of the following is written as a rational function?

According to the question

A rational function is a function that can be expressed as the quotient or ratio of two polynomial functions, where the polynomial in the denominator must have a degree of at least 1.

A rational function can be expressed as;

\rm Rational \ function =\dfrac{p(x)}{g(x)}

Then,

The required rational function is expressed as;

\rm Rational \ function =\dfrac{p(x)}{g(x)}

Where p(x) is (x-5) and g(x) is 3x.

Therefore,

The function is,

\rm Rational \ function =\dfrac{x-5}{3x}

Hence, the function can be expressed as a rational function is \rm\dfrac{x-5}{3x}.
