Answer:
6.5 seconds
Step-by-step explanation:
Keep in mind that when 
, this is the same height for both when the model rocket takes off and lands, so when the rocket lands, time is positive. Thus:
So, the amount of seconds that the model rocket stayed above the ground since it left the platform is 6.5 seconds

Answer:
- angle SVR = 30°
- angle PVR = 90°
- angle SVQ = 60°
- angle SVP = 120°
- angle RVQ = 30°
Step-by-step explanation:
As with finding distances on a number line, the easiest way is to subtract the smaller coordinate from the larger. Here, the "number line" is the arc at the edge of the protractor. The corresponding coordinates are ...
S: 40°
R: 70°
Q: 100°
P: 160°
The measure of an angle with its vertex at V will be the difference between the "coordinates" of the endpoints of the arc it intercepts. That is ...
m∠SVR = "R" - "S" = 70° -40° = 30°
The other angles are found the same way:
m∠PVR = 160° -70° = 90°
m∠SVQ = 100° -40° = 60°
m∠SVP = 160° -40° = 120°
m∠RVQ = 100° -70° = 30°

Step-by-step explanation:
4.5/4
Step-by-step explanation:
-2 (4x -15) -3 (5x^2 +7x +6 ) = -15x^2 -29x-12
-2 (7x +1 ) -5 (3x^2 +3x +3) = -15x^2 -29x -12
(-7x^2 -21x + 13) -(8x^2+8x+25) = -15x^2 -29x -12
(-17x^2+2x-3)+(2x^2-31x-9) = -15x^2- 29x -12
