Suppose that the terminal point determined by t is the point 12 13 , 5 13 on the unit circle. Find the terminal point determined

Tom [10]

Answer:

(a) (-12/13, 5/13)

(b) (12/13, -5/13)

(d) (12/13, 5/13)

Step-by-step explanation:

(a) The terminal point is effectively reflected across the y-axis, so the sign of the x-coordinate changes. (-12/13, 5/13)

(b) The terminal point is effectively reflected across the x-axis, so the sign of the y-coordinate changes. (12/13, -5/13)

(c) The terminal point is effectively reflected across the origin, so the signs of both coordinates change. (-12/13, -5/13)

(d) The terminal point is mapped to itself, so its coordinates remain unchanged. (12/13, 5/13)

Help with this algebra question

choli [55]

If two lines are perpendicular, the slope of one of the lines is the negative reciprocal of the other. Since we know the slope for one of our lines, $2$ m lets find the other:
$m=- \frac{1}{2}$

Now, lets use the point-slope formula to complete the equation of our perpendicular line:
$y-y_{1}=m(x-x_{1})$
$y-5=- \frac{1}{2} (x-2)$
$y-5=- \frac{1}{2}x+1$
$y=- \frac{1}{2} x+6$

We can conclude that our perpendicular line is $y=- \frac{1}{2} x+6$

The town of yarmouth is planning a skateboard park and needs to know the perimeter of the park. The property measures 7 yards by

fiasKO [112]

To get the perimeter, you get the sum of all the sides.
Therefore, the perimeter of the park here is 7+3+10+5 = 25 yards.
