Step-by-step explanation:

Tan² theta = sec² theta - 1

Cot² theta = cosec² theta - 1

Tan²+Cot² = sec²-1+cosec²-1

= sec²+cosec²-2

In the diagram triangles ABE and ACD are similar.

jolli1 [7]

Answer:

p = 7.2

q = 6.4

Step-by-step explanation:

if the triangles are similar then the side lengths must be proportional :

AC/BA = CD/BE

9/5 = p/4 cross multiply expressions

5p = 36 divide both sides by 5

p = 7.2

same goes for q

9/5 = (q+8)/8 cross multiply expressions

72 = 5(q+8) divide both sides by 5

14.4 = q+8 subtract 8 from both sides

6.4 = q

A small rocket is fired from a launchpad 15 m above the ground with an initial velocity left angle 400,450,600 right angle m/s.

vivado [14]

Answer:

v=<400, 450+3t, 600-9.81t> m/s

r=<400t, 450t+3 $t^{2}$ /2, 15+600t-9.81 $t^{2}$ /2> m/s

b) attach file

c) t=122.324s

d) z=18369.9854 m

Step-by-step explanation:

The equation for velocity of each component is v= $v_{0}$ +at, in this case the x-axis component has acceleration 0 $\frac{m}{s^{2} }$ , the y-axis component has acceleration 3 $\frac{m}{s^{2} }$ and the z-axis component has -g $\frac{m}{s^{2} }$ , where g=9.81 $\frac{m}{s^{2} }$ .
