The terminal side of theta passes through the point (-5,-6). what is the exact value of cos theta in simplified form?

ANSWER

EXPLANATION

The given point is (-5,-6).

This implies that ,

Hence opposite=6 units and adjacent=5 units.

The hypotenuse is,

Since the terminal side is in the third quadrant, the cosine ratio is negative.

Rationalize the denominator,

The correct choice is C.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
