1 answer:
Vinil7 [7]3 years ago

Answer:

\frac{17}{13}

Step-by-step explanation:

Given

tan x = \frac{5}{12} = \frac{opposite}{adjacent}

5 and 12 are the legs of a 5- 12- 13 right triangle with hypotenuse 13, thus

sin x = \frac{opposite}{hypotenuse} = \frac{5}{13}

cos x = \frac{adjacent}{hypotenuse} = \frac{12}{13}

Thus

sin x + cos x = \frac{5}{13} + \frac{12}{13} = \frac{17}{13}

Is y=x^2-6 a linear function and why
jarptica [38.1K]

Answer:

No.

Step-by-step explanation:

No, y=x²-6 is not a linear function.

This is because all linear functions have the highest exponent of 1. Anything equation that has a variable raised to a power other than 1 is not linear.

The equation provided as the highest exponent of 2. Thus, it's not linear.

From the provided graph, we can also see that this is quadratic instead of linear. The graph is a parabola instead of a line.
