For each function, state the vertex and whether the function has a maximum or minimum value. Explain how you decided? f(x) = -(x
nordsb [41]

Answer:

maximum value at (- 1, 6 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

• If a > 0 then minimum value

• If a < 0 then maximum value

y = - (x + 1)² + 6

with (h, k) = (- 1, 6 ) and a = - 1

Thus vertex = (- 1, 6 ) and is a maximum

Angles A and B are complementary. What is the value of x? 34 56 68 79
Lelu [443]

Answer: x = 34°


Explanation:


As per definition, complementary angles add up 90°.


In the figure you see angle A measures x + 22° and angle B measures x.


Therefore, according to the definition, you can set this equation:

       

             x + 22° + x = 90°


Solve for x:


  • start: x + 22 + x = 90
  • combine like terms: 2x + 22 = 90
  • subraction property: 2x = 90 - 22
  • do the operation: 2x = 68
  • division propery: x = 68/2
  • do the operation: x = 34

Answer: x = 34°

Triangle ABC IS an isosceles triangle AB=BC m
True [87]

Answer:

<em>The measure of angle A is 73°</em>

Step-by-step explanation:

<u>Isosceles Triangles</u>

An isosceles triangle is a triangle with exactly two congruent sides. The angles the congruent sides form with the third side are also equal.

The triangle ABC is isosceles and AB congruent with BC. The angle at B measures 34°.

The other two angles are congruent, i.e. their measures are the same. Since the internal angles of a triangle sum 180°:

2*m\angle A=180^\circ - 34^\circ =146^\circ

Thus:

m\angle A=146^\circ /2=73^\circ

The measure of angle A is 73°
