The table of values represents the function ​​ g(x) and the graph shows the function ​f(x)​.
Tanya [424]

Answer:

B, C

Step-by-step explanation:

x-intercepts are when y=0.  f(x) has two x-intercepts at (1, 0) and (5, 0).  g(x) also has two x-intercepts; (-3, 0) and (5, 0).  So the first one is false, and the second one is true.

The maximum value of f(x) is 2.  The maximum value of g(x) is 4.  So the third one is true.

The y-intercept is the value of y when x=0.  So the y-intercept of f(x) is -1, and the y-intercept of g(x) is 3.  So the fourth one is false.

Help me please. This is my last question
Crazy boy [7]

Answer: D. 44

Step-by-step explanation:

Here, we need to know the concept of trigonometry.

  • Sine (sin) = Opposite/Hypotenuse = O/H
  • Cosine (cos) = Adjacent/Hypotenuse = A/H
  • Tangent (tan) = Oppostie/Adjacent = O/A

-----------------------------------------------------------------------------

Given

- The adjacent side of angle x and the hypotenuse.

- We are going to use Cosine.

<u>Solve</u>

cos (x) = 15/21

       x  = cos⁻¹ (15/21)

       x  ≈ 44

Hope this helps!! :)
