When you raise a number to a negative exponent, change the exponent to a positive and make the complete number a fraction with 1 as the numerator.
5 ^-2 = 1/5^2

Answer:
Equation of line in slope-intercept form that passes through (4, -8) and is perpendicular to the graph
is below

Step-by-step explanation:
Slope of the equation
is 
Since slopes of perpendicular lines are negative reciprocal of each other, therefore slope of other line is given as

Equation of line in point slope form is given as

Here (x1, y1) = (4, -8)

Simplifying it further

Answer:
15°
Step-by-step explanation:
Since P is on the median of ΔABC, it is equidistant from points B and C as well as from C and Q. Thus, points B, C, and Q all lie on a circle centered at P. (See the attached diagram.)
The base angles (B and C) of triangle ABC are (180° -30°)/2 = 75°. This means arc QC of the circle centered at P has measure 150°. The diameter of circle P that includes point Q is defined to intersect circle P at R.
Central angle RPC is the difference between arcs QR and QC, so is 180° -150° = 30°. Inscribed angle RQC has half that measure, so is 15°. Angle PQC has the same measure as angle RQC, so is 15°.
Angle PQC is 15°.
