The constant of proportionality is: 3.85, because 19.25/5= 3.85. Hope this helps! :)
There are 180° in a triangle so you do
180- (30+30)
=180 - 60
=120
Therefore the answer is x = 120

Answer:
The jet will overtake the plane at 8:25 am.
Step-by-step explanation:
The distance
traveled by the plane after time
since it took off is modeled by the equation
![D_p = 270t](https://tex.z-dn.net/?f=D_p%20%3D%20270t)
And the distance
traveled by the jet after time
since the plane took off is given modeled by the equation
<em>(we set this up such that at </em>
<em> </em>
<em>)</em>
Now, the jet will overtake the plane when
:
![460t-460> 270t](https://tex.z-dn.net/?f=460t-460%3E%20270t)
![460t-270t> 460](https://tex.z-dn.net/?f=460t-270t%3E%20460)
![190t>460](https://tex.z-dn.net/?f=190t%3E460)
![\boxed{t> 2.42\: hours }](https://tex.z-dn.net/?f=%5Cboxed%7Bt%3E%202.42%5C%3A%20hours%20%7D)
Which is 2 hours and 25 minutes after 6:00 am, or at 8: 25 am; therefore, the jet will overtake the plane at 8:25 am.
Answer:the value of g(-2) is 21
Step-by-step explanation:
The given function is expressed as
g(x) = 3x^2-4x +1
To determine the value of g(-2), we would substitute x = -2 into the given function. It becomes
3(-2)^2 - 4(-2) + 1 = 3×4 +8 +1
= 12 + 8 + 1 = 21
