Answer:

30 = <8

Step-by-step explanation:

<4 and <8 are corresponding angles and corresponding angles are equal when the lines are parallel

<4 = <8

30 = <8

Hey there! :)

Answer:

m∠8 = 30°.

Step-by-step explanation:

Since AB || CD, m∠4 = m∠8 because they are corresponding angles. Therefore:

If m∠4 = 30°, m∠8 = 30°.

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 $\frac{m}{s^{2} }$ .

The equation for position of each component is x= $x_{0}$ + $v_{0}$ t+a $t^{2}$ /2,

with < $x_{0}$ , $y_{0}$ , $z_{0}$ >=<0,0,15>.

c) This time is t when z=0, with positive sign.

d)Solving the equation $V_f^{2}$ = $V_o^2$ + 2*a*(z- $z_{0}$ ) for z, with $V_f$ =0.

If you distribute a negative factor, should you flip the inequality symbol? And why be specific

Alchen [17]

You flip is when you mulitply the whole equation by a negative
not when you distribute a negative
if yo had
-3(x+4)>x
you wouldn't flip the negative symbol when distributing then -3

but if you had
-3(x+4)>-x
you would eventually have to multiply by -1 to make +1x

because they will be differente
exaple

12>3 is true
if yo multiply negative
-12>-3 is fale
-12<-3 is true

anothe rexample with placeholders
x<x+2
mulitply -1
-x>-x-2
false
-x<-x-2
true
that is why we flop the inequality symbole
