Evaluating the Six Trigonometric Function Question attached
ziro4ka [17]
If tan theta is -1, we know immediately that theta is in either Quadrant II or Q IV.  We need to focus on Q IV due to the restrictions on theta.

Because tan theta is -1, the ray representing theta makes a 45 degree angle with the horiz axis, and a 45 degree angle with the negative vert. axis.  Thus the hypotenuse, by the Pythagorean Theorem, tells us that the hyp is sqrt(2).
Thus, the cosine of theta is adj / hyp, or +1 / sqrt(2), or [sqrt(2)]/2

The secant of theta is the reciprocal of that, and thus is

Y=6x/5 +27 find y-intercept and slope
mixas84 [53]

Answer:

  1. General equation of a line is given by y = mx +c, where m is the gradient /slope, c is the intercept. To find for the intercept on y- axis, put x = 0.
  2. y =  \frac{6(0)}{5 }  + 27 \\ y =  \frac{0}{5}  + 27 \\ y = 27 \\ therefore \: the \: intercept \: on \: y \: is \: 27 \\
  3. By comparison,
  4. y =  mx +  \: c \\ y =  \frac{6}{5} x  \:  +27 \\ m =  \frac{6}{5 \: }  \: \\  hence \: slope \: is \:  \frac{6}{5}
