2. Create a linear function that has a rate of change of 3 and a solution at (6, 12).
Ksivusya [100]

Answer:

y = 3x - 6

Step-by-step explanation:

A linear function has the following format:

y = ax + b

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.

Rate of change of 3

This means that a = 3

So

y = 3x + b

A solution at (6, 12).

This means that when x = 6, y = 12. So

y = 3x + b

12 = 3*6 + b

b = -6

The linear function is:

y = 3x - 6

What is the value of the 30th percentile for the data set 6283, 5700, 6381, 6274, 5700, 5896, 5972, 6075, 5993, 5581?
sineoko [7]

To solve this problem, we should remember that the percentile rank of a single value is the rank of that value in the series of data set when that data set is arranged in ascending order.

Therefore arranging the data set, gives the sequence:

5581, 5700, 5700, 5896, 5972, 5993, 6075, 6274, 6283, 6381

<span>Since we are to find the 30th percentile (30 %) and there are a total of 10 values, therefore the 30th percentile is:</span>

10 * 30% = 3

<span>This means we look for the 3rd number in the ordered sequence.</span>

<span>
</span>

<span>Answer: 5700 is the 30th percentile of the series</span>

Find the radius r of the circle. Round your answer to the nearest tenth.
Genrish500 [490]

First off we need to use the formula S = rΘ

S - is the arc length

Θ - is theta which is the radian measure

r - is the radius

In this problem we need to find r

So, our equation would look like:

S ÷ Θ = r

Before we solve though, we need to convert the degrees to radians:

To convert from degrees to radians, multiply the degrees by π/180° radians:

60 x π/180 = 1.0472

If you input the numbers you get:

10.2 / 1.0472 = 9.740

The radius is 9.7 yards.

PLEASE HELP WILL GIVE BRAINLIEST! What is the following sum? Assume x &gt; or equal to 0 and y is &gt; or equal to 0.
Ira Lisetskai [31]

Answer:

Option (b) is correct.

The sum of given expression  \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y} is  2xy\sqrt{y}+2xy^2\sqrt{x}

Step-by-step explanation:

Given:Expression \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}

We have to find the sum of the given expression and choose the correct from the given options.

Consider the given expression  \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}.

\sqrt{x^2y^3} can be written as \sqrt{x^2y^2y}=xy\sqrt{y}

Also, 2\sqrt{x^3y^4} can be written as 2\sqrt{x^3y^4}=2\sqrt{x^2x(y^2)^2}=2xy^2\sqrt{x}

Now, the given expression becomes,

\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}

=xy\sqrt{y}+2xy^2\sqrt{x}+xy\sqrt{y}.

Now, adding like term, terms having same variable with same degree.

=2xy\sqrt{y}+2xy^2\sqrt{x}.

Thus, The sum of given expression  \sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y} is  2xy\sqrt{y}+2xy^2\sqrt{x}
