Jane has a pre-paid cell phone with NextFell. She can't remember the exact costs, but her plan has a monthly fee and a charge fo
kolbaska11 [484]

Answer:

  • C = 0.30x +22
  • $165.10

Step-by-step explanation:

A) Let x represent minutes used, and C represent monthly charge. We are given two (x, C) pairs: (370, 133.00) and (530, 181.00)

We can use these in the 2-point form of the equation for a line.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  C = (181 -133)/(530 -370)(x -370) +133

  C = 48/160(x -370) +133

  C = 0.30x -111 +133

  C = 0.30x +22

__

B) For x = 477 minutes, the charge will be ...

  C = 0.30(477) +22 = $165.10 . . . . for 477 minutes

How do I solve this? Thank you.
MariettaO [177]

Answer:

Heyya little student!

Sin means \frac{opposite }{hypotenuse}

5 is the hypotenuse (its opposite to 90 degrees )

So, sin β would be:-

the side opposite to the angle β divided by the hypotenuse of the triangle.

The side opposite to β is 4

and as I said earlier, the hypotenuse is 5

<h2>So, sin β would be:-</h2><h2>\frac{4}{5}</h2>

I hope it helped you!

Keep learning

and never stop smiling

You Are Awesome!
