Mathematics

Answer:

Step-by-step explanation:

The angles <JKL, <EKL, and <JKE form a full angle which means their sum is equal to 360:

134 + 21x + 6 + 5x = 360 add like terms

140 + 26x = 360 subtract 140 from both sides

26x = 220 divide both sides by 26

x = 8.4 approximately

to find the angle m<JKL replace x with the value we found.

Given y-k=a(x-h)^2, a=-1, h&gt;0, k&lt;0 in which quadrant is the vertex
ad-work [718]

Answer:

Since the equation is a quadractic, the graph would be a parabola.

With a being -1, the parabola will represent a reflection of the y values. In other words, the parabola will be upside down and the vertex will be a maximum value. Ultimately, the <em>a </em>in the function doesn't determine the location of the vertex.

Since the k value is negative, that means the equation begins <em>y - (-k)</em>. The K value being negative restricts the transformation of the parabola to being down <em>k</em> number of units. The location of moving the parabola down places the vertex in the third or fourth quadrant.

The <em>h</em> value being positive means that the parabola is shifted to the right <em>h</em> number of units. For example, if the parabola <em>f(x) = x²  </em>has a vertex at (0,0), the parabola <em>f(x) = (x-2)²</em> must have a vertex at (2,0) because 2 - 2 = 0. Shifting right places the vertex of the parabola in the first or fourth quadrant.

Therefore the k value and h value restrictions must overlap in the fourth quadrant.
