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
Playing football soccer that requires being proficient in all health-related components. These components include cardiorespiratory endurance, body composition, flexibility, muscular strength and muscular endurance.
The health-related components of physical fitness are key factors in all sports physical fitness such as walking, running, gym, swimming, cycling, soccer, etc.
Cardiovascular endurance refers to the ability that the heart and lungs have to provide oxygen to all body cells, which is fundamental during a football soccer game.
Flexibility refers to the ability of muscles to lengthen, thereby allowing your joints to move through a range.
Muscular strength. When playing soccer, muscle strength indicates the amount of force you can make when you kick a ball.
Muscular endurance refers to the ability that muscles in your body have to perform movements without fatigue. In this case, muscular endurance makes special reference to the muscles in your lower limbs or legs.
