The function given represents the temperature of a sauna set to 180°F. The temperature goes up and down throughout the day. Find

nasty-shy [4]

Answer:

The answer is below

Step-by-step explanation:

Given the function as:

f(x)=5sin(πx / 15)+180,

a) The angular frequency (ω) = 2π * frequency

but ω = π/15, hence:

π/15 = 2π * frequency

frequency = (π/15)/2π

frequency = 1/30 hertz

Period (T) = 1/frequency = 1/(1/30) = 30 seconds

b) The period is 30 seconds. This means that it reaches the maximum temperature every 30 seconds.

In one hour (3600 s), the number of times the function reaches a maximum temperature = 3600 s / 30 s = 120

If you're trying to solve for x, you need to use the quadratic formula.
$\frac{-b+/- \sqrt{b^2 - 4(a)(c)} }{2a}$
Plug in the numbers from the standard form of a quadratic equation
(which is $ax^2 + bx + c = 0$ )
$\frac{34+/- \sqrt{34^2 - 4(16)(15)} }{2(16)}$
From here, this solves down to
$\frac{34+/- \sqrt{196}}{32}$
Take the square root of 196, which is 14
$\frac{34+/- 14}{32}$
Now, you can solve for both the + and - variations on the equation.
The solutions to your equation are 1.5 and 5/8 (probably)
