Tell whether the given value is a solution of the equation: n/12 = 2; n = 26

Mathematics

Anika [276]3 years ago
7 0

Answer:

no, 26 it is not a solution to the equation

Step-by-step explanation:

simply substitute n for 26 since n=26

n/12=2

26/12=2

2.17=2

that does not make sense (since 2.17 is not 2), so, no, 26 is not a solution

(6.) The point A(-5,12) lies on the circle whose equation is x + y2 = 169. What is the secant of
Gnoma [55]

The secant of the angle through a point (-5, 3) is -13/5  

<h3>Equation of a circle</h3>

The equation of a circle with center (0,0) is given by

x² + y² = r² where r = radius of circle

Now, comparing this to the equation of the given circle x² + y² = 169,

⇒ r² = 169

r = √169

r = 13

<h3>Secant of angle </h3>

The secant of the angle through a point (x, y) is secФ = r/x where

  • r = radius of circle and
  • x = x-coordinate of point

Now for the point A(-5,12), x = -5.

Since r = 13

secФ = r/x

= 13/-5

= -13/5  

So, The secant of the angle through a point (-5, 3) is -13/5

On the set of axes below, draw the graph of y=x^2-4x-1
never [62]

9514 1404 393

Answer:

  axis of symmetry: x = 2

  see below for a graph

Step-by-step explanation:

You can complete the square to put the equation in vertex form.

  y = (x^2 -4x +4) -1 -4

  y = (x -2)^2 -5 . . . . . . vertex is (2, -5)

The equation of the axis of symmetry is the equation of the vertical line through the vertex:

  x = 2 . . . . . axis of symmetry

__

Points on the graph are easily found by using integer values on either side of x=2. Points on one side of the axis of symmetry are mirrored on the other side of it.
