Answer:
<em>d) The equation of the line passing through the points </em>
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given points are ( 0, -4) and (2 ,0)
slope of the line
<u><em>Step(ii):</em></u>-
The equation of the line passing through the point ( 0,-4) and having slope
2 ( y +4) = -x
2 y + 8 = -x
2 y = - x - 8
<u><em>Final answer:-</em></u>
<em>The equation of the line passing through the points </em>

Answer: a) -7/12 ft/s, -20 ft/s, -7 ft/s
b) 527/24 Ft²/s
c) 2/25 rad/sec
Step-by-step explanation:
a) b=7 ; a^2+b^2 = 25^2
a^2+b^2 = 625
Differentiate w.r.t = 2a (da/dt) + 2b ( db/dt) = 0
As found from above put a=24 b=7,15 and 24. You will get the reuqired answer.
b) Area of the triangle = 1/2 * b*h
differentiate wrt to time leads to the following relation:
c) sin (Θ) = b/25
differentiate it again to give
