Answer:

  (3)  35·cos(57°)

Step-by-step explanation:

The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

For the given triangle, this is ...

  cos(57°) = QR/QS

Multiplying by QS gives ...

  QS·cos(57°) = QR

Filling in the value of QS, we have ...

  QR = 35·cos(57°)

Find the solution of this system of equations.
beks73 [17]
<span>x= -8 + y
-9x + 6y= 9

substitute </span>x= -8 + y into -9x + 6y= 9

-9x + 6y= 9
-9(-8 + y) + 6y= 9
72 - 9y + 6y = 9
-3y = -63
    y = 21

<span>x= -8 + y
</span><span>x= -8 + 21
x = 13

solution (13, 21)</span>

What is the range of the function f(x)= square root of x-8+6
Shtirlitz [24]

Answer:

  • The range of the given function is  [6, + ∞)

Step-by-step explanation:

It is assumed the function is:

  • f(x)=\sqrt{x-8} +6

We know the square root is non-negative, so:

  • x - 8 ≥ 0  therefore the function gets values

  • f(x) ≥ 0 + 6
  • f(x) ≥ 6

We can show this as:

  • f(x) ∈ [6, + ∞)
