10POINTSwhich quadratic function has the largest positive solution x^2-25=0

Leno4ka [110]

$x^2-9 = 160$ has the largest positive solution

Step-by-step explanation:

We can observe the given quadratic equations one by one.

We can see that the given quadratic equations are of the form

$x^2 = c^2$

OR somehow simplify to the given form

The solution is:

x = ±c

So,

Option 1:

$x^2-25 = 0\\x^2 = 25\\\sqrt{x^2} = \sqrt{25}\\x = 5\ \ , x=-5$

Option 2:

$x^2+10=154\\x^2+10-10 = 154-10\\x^2 = 144\\\sqrt{x^2} = \sqrt{144}\\x = 12\ \ \ , x = -12$

Option 3:

$x^2-9=160\\x^2-9+9 = 160+9\\x^2 = 169\\\sqrt{x^2} = \sqrt{169}\\x = 13\ \ \ , x = -13$

Option 4:

$x^2+49=50\\x^2+49-49 = 50-49\\x^2 = 1\\\sqrt{x^2}= \sqrt{1}\\x = 1\ \ \ , x= -1$

We can clearly see that:

$x^2-9 = 160$ has the largest positive solution

27-4(26-2×3)to the 2nd power

Svetlanka [38]

First do the ones in the parentheses. So, 2x3=6. 26-6=20. 20^2=400. Now you have 27-4x400. 4x400=1600. 27-1600=-1573.

Line segment AB has endpoints A(6, 1) and B(3, 8). Find the coordinates of the point that divides the line segment directed from

Pavel [41]

Ratio = 2:3 = 2/5

Distance between the x coordinates: 3
Distance between the y coordinates: 7

x: 3 * 2/5 = 1.2
y: 7 * 2/5 = 2.8

x coordinate of point: 6 - 1.2 = 4.8
y coordinate of point: 1 + 2.8 = 3.8

So the point that divides the segment AB in the ratio of 2:3 is (4.8 , 3.8) or (24/5 , 19/5)

Hope this helps :)
