Solve for x. round to the nearest tenth​

Mathematics
1 answer:

3 0

Answer:

43.1

Step-by-step explanation:

We can figure this out by using a bit of simple trigonometry

Using the available values we know we have to figure out x using cos because it includes the adjacent and hypotenuse values.

"Soh Cah Toa"

Cos(x) = Adjacent / Hypotenuse

Cos(x) = 8/11

Cos(x) = 0.73

Using cos^{-1} we can figure out x from the side length

x = cos^{-1}(0.73)

x = 43.1 degrees (rounded)

Is the function in the table linear or nonlinear and why? x y 0,−100 and 1,-50 and 2,0 and 3,100 and 4,150. (A)The function is n
Studentka2010 [4]

Answer:

The correct option is c.

Step-by-step explanation:

Linear function: The rate of change of a linear function is always constant.

Non-Linear function: The rate of change of a non-linear function is not constant.

From the given coordinate pairs it is noticed that the function is passing through the points (0,-100), (1,-50), (2,0), (3,100) and (4,150).

m=\frac{y_2-y_1}{x_2-x_1}

The slope of function for points (0,-100) and (1,-50) is

m_1=\frac{-50-(-100)}{1-0}=50

The slope of function for points (2,0) and (3,100) is

m_2=\frac{100-0}{3-2}=100

Since the slopes of function are different, therefore the given function is non-linear.

The function is not linear because the rate of change is not constant and option c is correct.
