Answer:
18.6x + 3.6
Explanation:
A rocket scientist needs to find the overall thrust of a new rocket design. The rocket has two stages: Stage A and Stage B. Stage A's thrust is defined by the expression 11.2x + 6.4 and Stage B's thrust is defined by the expression 7.4x − 2.9.
Solution:
The rocket thrust is the force that helps in moving the rocket through air and through space. For a multistage rocket, the overall thrust is gotten by summing all the thrust experienced in each of the stages.
Hence the overall thrust for this problem is given by the equation:
Overall thrust = Stage A thrust + stage B thrust
Overall thrust = (11.2x + 6.4) + (7.4x − 2.9)
Overall thrust = 18.6x + 3.6
When a cell is "at rest" it is in a state called the resting potential. In this state, neurons are more negatively charged ions inside the cell than outside the cell.
False, they're signs of physical stress
Answer:
produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs. This vibration produces the sound wave for your voice. In order for the sound to be clear and not raspy or hoarse, the vocal folds must vibrate together symmetrically and regularly
