Q10 Q2.) Find the standard form of the equation of the parabola satisfying the given conditions.

Kipish [7]

Hello!!

Equation forms:

$y = \frac{x^2}{4} + \frac{x}{2} + \frac{13}{4}$

Therefore, $x^2 - 2x + 4y - 13 = 0$

And, this is how your graph would look

Good luck :)

The coordinate of centroid of a triangle whose vertices are (1,3,-2), (4,5,0), (6,3,9) is = ……………….

Dominik [7]

Answer:

$C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})$

Step-by-step explanation:

Given

$(x_1,y_1,z_1) = (1,3,-2)$

$(x_2,y_2,z_2) = (4,5,0)$

$(x_3,y_3,z_3) = (6,3,9)$

Required

Determine the coordinates of the centroid

Represent the coordinates with C.

C is calculated as follows:

$C = (\frac{1}{3}(x_1+x_2+x_3),\frac{1}{3}(y_1+y_2+y_3),\frac{1}{3}(z_1+z_2+z_3}))$

Substitute values of x and y in the given equation

$C = (\frac{1}{3}(1+4+6),\frac{1}{3}(3+5+3),\frac{1}{3}(-2+0+9}))$

$C = (\frac{1}{3}(11),\frac{1}{3}(11),\frac{1}{3}(7}))$

$C = (\frac{11}{3},\frac{11}{3},\frac{7}{3})$

<em>The above is the coordinate of the centroid</em>

What do the solutions of a quadratic equation represent graphically? What is the maximum number of solution(s) given by solving

astra-53 [7]

Answer:

The solutions of a quadratic equation on a graph is the point where the graph cuts across the x and y axes. The maximum number of solutions given by solving a quadratic equation is 2 solutions because the maximum power in a quadratic equation is power 2

Write the equation of the line in slope intercept form for the lone with a slope of 1/3 and a y intercept of (0,4)

Anastasy [175]

Answer:

$y=\frac{1}{3} x+4$

Step-by-step explanation:

Slope-intercept from is:

$y=mx+b$

m is the slope and b is the y-intercept. Insert slope:

$y=\frac{1}{3}x+b$

The y-intercept is at point (0,4). The y-intercept is when x equals 0, so take the value of y and insert into the equation:

$y=\frac{1}{3} x+4$

Finito.
