6. Researchers who have been studying the alarming rate at which the level of the Dead Sea has been dropping
have shown that the density d (x) (in g per cm³) of the Dead Sea brine during evaporation can be estimated by the
function
d(x)=1.66 0.90x+0.47x²,
where x is the fraction of the remaining brine, 0≤x≤1.
a) Estimate the density of the brine when 60% of the brine remains.
b) Find and interpret the instantaneous rate of change of the density when 60% of the brine remains.

- A ladder 27 feet long leans against a wall and the foot of the ladder is sliding away at a constant rate of 3 feet/sec. Meanwhile, a firefighter is climbing up the ladder at a rate of 2 feet/sec. When the firefighter has climbed up 6 feet of the ladder, the ladder makes an angle of л/3 with the ground. Answer the two related rates questions below. (Hint: Use two carefully labeled similar right triangles.) (a) If h is the height of the firefighter above the ground, at the instant the angle of the ladder with the ground is л/3, find dh/dt= feet/sec. (b) If w is the horizontal distance from the firefighter to the wall, at the instant the angle of the ladder with the ground is л/3, find dw/dt= feet/sec.arrow_forwardTwo cars start moving from the same point. One travels south at 60 mi/h and the other travels west at 25 mi/h. At what rate (in mi/h) is the distance between the cars increasing four hours later? Step 1 Using the diagram of a right triangle given below, the relation between x, y, and z is z² = x²+ +12 x Step 2 We must find dz/dt.
