 1 mL  = 1*10^-3 L

if every student needs 88 ml  the total ml needed are 3344ml

3344ml * 1*10^-3L/1ml= 3.344 L
that will mean you need 4 bottles or, 3 and 0.344 of another

Describe the location of point (−5, −5, 5) in three-dimensional coordinate space.
Diano4ka-milaya [45]
Here's a really cool website that let's you input 3D points!

From the attached picture you can see that the point has moved back 5 units, to the left 5 units, and up 5 units.

Graph the relation shown in the table. Is the relation a function? Why or why not?
Bogdan [553]
Answer: choice B) yes; only one range value exists for each domain value

---------------------------------
---------------------------------
Explanation:

The inputs are x = -3, x = -1, x = 1, x = 5. They are the first coordinate listed of each point. We don't have any x values repeating so this means we have a function. Each input leads to exactly one output which is what choice B is stating. The domain is the set of allowed inputs, or x values. The range is the set of possible y outputs. 

If we had something like (1,2) and (1,5) then the input x = 1 leads to more than one output (y = 2 and y = 5). This example means we don't have a function

If you graph the points (-3, -2), (-1,0), (1,0) and (5,-2) as shown in the attached image, then you'll notice that it is impossible to pass a single line through more than one point. Therefore this graph passes the vertical line test visually proving we have a function. 

Going back to the example with (1,2) and (1,5), plotting these two points leads to the vertical line test failing implying we don't have a function.

An elliptical-shaped path surrounds a garden, modeled by quantity x minus 20 end quantity squared over 169 plus quantity y minus
Margaret [11]

The <em>maximum</em> distance between any two points of the ellipse is 34 feet.

<h3>Procedure - Determination of the distance between two points of a ellipse</h3>

The maximum distance between any two points of a ellipse is the <em>maximum</em> distance between the ends of the ellipse along the <em>longest</em> axis, which is parallel to the y-axis in this case.

In addition, the equation of the ellipse in <em>standard</em> form is defined by this formula:

\frac{(x-h)^{2}}{a^{2}} + \frac{(y-k)^{2}}{b^{2}} = 1 (1)

Where:

  • h, k - Coordinates of the center of the ellipse.
  • a, b - Lengths of each semiaxis.

Hence, the maximum distance (d_{max}), in feet, is calculated by this formula:

d_{max} = 2\cdot b (2)

If we know that b = 17, then the maximum distance between any two points of the ellipse is:

d_{max} = 2\cdot (17\,ft)

d_{max} = 34\,ft

The <em>maximum</em> distance between any two points of the ellipse is 34 feet. \blacksquare

<h3>Remark</h3>

The statement is incomplete and poorly formatted, correct form is presented below:

<em>An elliptical-shaped path surrounds a garden, modeled by </em>\frac{(x-20)^{2}}{169} + \frac{(y-18)^{2}}{289} = 1<em>, where all measurements are in feet. What is the maximum distance between any two points of the path.</em>

Please you can help me. Thanks.

Answer:

Using Math Papa Algebra Calculator I was able to simplify to:

-81x^5+1198x^3-896x=0

In further detail this equation can be factored and then solved for the multiple x-values given, which are: x=0 or x=−3.7416573867739413 or x=3.7416573867739413 or x= -8/9 or x=8/9

Step-by-step explanation:

I used a punnet square to solve for the simplified equation, from there I used Math Papa Algebra Calculator.

I would answer with the simplified answer, sorry I'd need more specifics to answer this question fully.

Once again the simplified is -81x^5+1198x^3-896x=0
