Which expression represents the distance between point (0, a) and point (a, 0) on a coordinate grid?

o-na [289]

Answer:

$\sqrt{2} a$

Step-by-step explanation:

The distance between point (x1,y1) and (x2,y2) on a coordinate plane is given by expression $\sqrt{(x1-x2)^2+(y1-y2)^2}$

In the problem given coordinate points are

(0, a) and (a, 0).

Thus, distance between these points are given by

$distance = \sqrt{(x1-x2)^2+(y1-y2)^2}\\=>distance = \sqrt{(0-a)^2+(a-0)^2}\\=>distance = \sqrt{(a)^2+(a)^2}\\\\=>distance = \sqrt{2a^2}\\=>distance = \sqrt{2} a$

Thus , expression $\sqrt{2} a$ gives the distance between point (0, a) and point (a, 0) on a coordinate grid.

Which of the following illustrate the commutative property? select all that apply

Genrish500 [490]

For this case we have that the commutative property establishes that the order of the factors does not alter the product. Example:

$5 * 6 = 6 * 5\\4 + 3 = 3 + 4$

Then we have the following options illustrate the property:

$3 + 4 + 6 = 3 + 6 + 4 = 13\\9 * 2 * 7 = 7 * 9 * 2 = 126\\2 + 3 + 1 = 3 + 1 + 2 = 6\\5 + 2-4 = 5-4 + 2 = 3$

It is necessary to emphasize that option b illustrates the associative property and in option c equality is not fulfilled

Answer:

Option A, D, E, F

What is the system of inequalities associated with the following graph?

slamgirl [31]

One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3

and slope m = $\frac{(-3-3)}{0-(-2)}$

$= \frac{-6}{2}= -3$

So the equation of line will be $y= -3x -3$

And the inequality should be $y\geq -3x-3$

Or $3x +y \geq -3$

And the other line passes through (-2,3) and (0,2)

So the y intercept is b=2

and the slope is $m= \frac{2-3}{0-(-2)} = \frac{-1}{2}$

So the equation of line will be $y= \frac{-1}{2} x +2\\and the inequality should be y \leq \frac{-1}{2} x+2$

$2y +x \leq 4$

So answer is $3x +y \geq -3, x+2y\leq 4$

(09.02 HC)

Vesna [10]

We factor the equation to get:

-(x-25)^2+361

In the form a(x-h)^2+k, the vertex is (h, k), so the vertex is (25, 361). This means that the studio makes the most profit from selling 25 memberships, and thus makes 361 dollars.

B. The x-intercepts are the values of x for which f(x) is 0. This equation can be factored as (-a+6)(a-44)=0, with solutions 6 and 44. Therefore, by selling either 6 memberships or 44 memberships, the studio breaks even, neither making nor losing money.
