Answer:
y=2/3x-1
Step-by-step explanation:
Like any other polynomial, you judge the number of solutions by the highest degree of the polynomial. This is a second degree polynomial so it has 2 solutions. They are x = +[sqrt(cos x)] and x = - [sqrt(cos x)]. If you graph those on a calculator the positive portion of the graph is above the x axis and the negative portion is below the x axis. It's really cool looking. You should graph it to see.

Answer: 10 cosec (62°)
Step-by-step explanation:
The given triangle in the problem is a right triangle. This means that we can use SohCahToa to solve for the length of our hypotenuse (Line A to C).
** SohCahToa is a way for you to memorize special trigonometric functions that can be used:
Soh - Sin = Opposite / Hypotenuse
Cah - Cos = Adjacent / Hypotenuse
Toa - Tan = Opposite / Adjacent **
For this triangle, we can use the angle, 62°, to determine the hypotenuse. We will use x to represent the value between A and C. If you examine the sides of the triangle, you'll see that the side opposite of our angle is 10.
Because we have values that are located opposite to the angle and on the hypotenuse, we will use Sin(θ) = Opposite / Hypotenuse.
** θ represents your angle **
Sin(θ) = 10 / x
We want x by itself so you'll need to multiply x to both sides and then divide by sin(θ). This should give you the following: x = 10 / sin(θ)
Being that 1 / sin(θ) = cosec(θ), you can substitute 1 / sin (θ) for cosec(θ).
This would give you x = opposite •
cosec(θ) which is the same as x = 10 cosec (62°).
I apologize if I didn't explain that clearly enough :/ I hope it helps you out a lil bit though!
The absolute value gives the positive value of any given number inside the symbol. The absolute equation is,
2.5 = I d - 2I
The values of d can be calculated through,
2.5 = d - 2
d = 4.5
Also,
-2.5 = d - 2
-2.5 + 2 = d
d = -0.5
Thus, the maximum value of the temperature is 4.5 and the minimum value of the temperature is -0.5.
