table 1.18 gives the average temperature, t, at a depth d, in a borehole in belleterre, quebec.13 evaluate δt/δd on the the following intervals, and explain what your answers tell you about borehole temperature.
(a) 25 ≤ d ≤ 150
(b) 25 ≤ d ≤ 75
(c) 100 ≤ d ≤ 200

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
