The <em>vertex</em> coefficient of the parabola with vertex (- 5, - 2) and the point (- 4, 2) is equal to 1.

<h3>What is the vertex coefficient of the equation of the parabola?</h3>

In this question we must find the <em>vertex</em> coefficient of the equation of the parabola, which is the <em>vertex</em> form of the <em>quadratic</em> equation:

y - k = C · (x - h)²

If we know that (h, k) = (- 5, - 2) and (x, y) = (- 4, 2), then the vertex coefficient is:

2 - (- 2) = C · [- 4 - (- 2)]²

4 = C · (- 2)²

C = 1

The <em>vertex</em> coefficient of the parabola with vertex (- 5, - 2) and the point (- 4, 2) is equal to 1.

Tell me what the slope and y intercept means to you
natka813 [3]
In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis)

What is the equation of the line that is perpendicular to 3x -6y =2 and contains the point (-2,--5)​
julsineya [31]

Answer:

y=-2x-12

Step-by-step explanation:

first, putt 3x-6y=2 in standard form:

subtract 3x from both sides: -6y=-3x+2

divide both sides by -6 to isolate y: y=1/2x-1/3

if the other line is perpendicular to this, you must find the slope by finding the opposite reciprocal of 1/2x: -2

now we have 2 points a slope, so we use the point-slope formula: y-y1=m(x-x1)

y+2=-2(x+5)

Use the distributive property: y+2=-2x-10

subtract 2 for both sides to isolate y: y=-2x-12

The lengths of the sides of a rectangle are 12.4 and 26. What are the measures of the angles between its diagonals? Round your a
Sergeu [11.5K]

Answer:

129 and 51 degrees.

Step-by-step explanation:

Drawing a diagonal gives us a triangle  with the opposite side = 12.4 and the adjacent side = 26.

tan x = 12.4 / 26

x = 25.497 degrees.

The other angle will be 90 - 25.497

= 64.503 degrees.

One of the diagonal angles is  180 - (2*25.497)

= 129 degrees

and the other  is 180 - 129 = 51 degrees.
