a) Altitude of triangle ABC
b) Angle bisector of angle H
c) Median of triangle JKL
0.5,0.55,0.005,0.505 is my answer
please can i have a brainliest
Diving company A charges $30 per hour for diving lessons. Diving company B charges only $22 per hour but they need a $48 down payment. At how many hours would the price for company A be equal to company B?
30x=48+22x
30x-22x=48
8x=48
x=6
Hope this helps!
Suppose,
x = distance of the man
<span>s = length of the shadow</span>
<span>Using the idea of similar triangles</span>
<span>6/s = 23/(x + s) </span>
<span>Simplifying:</span>
we get,
<span>6(x + s) = 23s </span>
<span>6x + 6s = 23s </span>
<span>6x = 17s </span>
<span>Differentiating with respect to time, </span>
<span>6(dx/dt) = 17(ds/dt) </span>
<span>Manipulating the above equation for ds/dt,</span>
<span>ds/dt = (17/6)(dx/dt) </span>
<span>ds/dt = (17/6)(6) </span>
<span>ds/dt = 17 ft/sec.</span>
