Find c to two decimal places and find the measure of angle B. Angle A = 58°, Side AC = 5, Side BC = 8, Find side C. Angle C is 9
KATRIN_1 [288]

Answer:

  • c = 9.43
  • m∠B = 32°

Step-by-step explanation:

Side c = AB can be found using the Pythagorean theorem:

  c² = a² + b² = 8² +5² = 89

  c = √89 ≈ 9.43

__

Angle B is the complement of angle A, so is ...

  B = 90° -A = 90° -58° = 32°

c is approximately 9.43; the measure of angle B is 32°.

Use the method of symmetry to find the extreme value of each quadratic function and the value of x for which it occurs.
-BARSIC- [3]

Answer:

  • See below

Step-by-step explanation:

The x-intercepts are the points with y- coordinate of 0

  • (x - 3)(x + 8) = 0
  • x - 3 = 0 or x + 8 = 0
  • x = 3 or x = - 8

a) x-intercepts are

  • 3 and - 8

b) midpoint of x-intercepts is

  • (3 - 8)/2 = - 5/2 = - 2.5

c) The extheme value has x- coordinate of - 2.5 and y- coordinate

  • (-2.5 - 3)(- 2.5 + 8) = (-5.5)(5.5) = - 30.25

d) f(- 2.5) = - 30.25

Step-by-step explanation:

In this case, find the least common mutiple or LCM.

<u>EXAMPLE OF LCM:</u>

There are two integers a and b marked as LCM ( a, b ), the LCM is the smallest positive integer that can be divisible by both a and b.

So LCM(18,42) =

18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198 ...\\42, 84, 126, 168, 210, 252, 294 ...

The LCM is 126, it is the least common multiple.
