What are the domain and range of f(x) = (1/6)x + 2?
Black_prince [1.1K]
F(x)=x/6+2

There is no restriction upon the values of x, or the values of y.

So the domain and range are both the set of all real numbers.

x=(-oo, +oo) and y=(-oo, +oo)

This can be further seen by the fact that this is a line with a slope of 1/6.  So there is no restriction upon x as all values of x produce real values of y.  And y approaches -oo as x approaches -oo and y approaches +oo as x approaches +oo.

Find the lengths of sides marked with variables (x, y, w, z). Show all work
natita [175]

Answer:

  • 1) 19.07 m, 2) 80.10 ft, 3) 56.79 m

Step-by-step explanation:

Use <u>trigonometry</u> to solve for unknowns.

<h3>1) Use sine</h3>
  • <em>sine = opposite leg / hypotenuse</em>
  • sin 27° = x/42
  • x = 42 sin 27°
  • x = 19.07 m (rounded)

<h3>2) Use tangent</h3>
  • <em>tangent = opposite leg / adjacent leg</em>
  • tan 23° = 34/x
  • x = 34 / tan 23°
  • x = 80.10 ft

<h3>3) Use cosine</h3>
  • <em>cosine = adjacent leg / hypotenuse</em>
  • cos 48° = 38/x
  • x = 38 / cos 48°
  • x = 56.79 m (rounded)

Question in the imagee
Ludmilka [50]

Answer:

Option A   (7×3) + 1/2(7×6)

Step-by-step explanation:

Divide this shape into a square and a triangle

For area of square the formula is

    Area = A = L ×W

From shape of square

7 seven boxes are yellow so L=7 and width W=3

   A  =  7 × 3

For triangle formula is

    A = (1/2)bh

    A = (1/2)(7×6)

Add them

    A = (7×3) + 1/2(7×6)
