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
The answer is muscle endurance
I believe the best choice will be option 3
Answer:
Vaccines have been around since 1796 preventing people from diseases and decreasing death rates. I believe due to the modern vaccines and medicine people have been living longer than life expectancies in the 1700's and 1800’s, which was between 30 and 40 years. Vaccines train the human body to recognize viruses or bacteria and the antigens (molecule capable of inducing an immune response) will start attacking the virus or bacteria before it tries to spread and cause sickness once it is has recognized it. However, vaccines are not always 100% safe because they can come with side effects. For example, the Hepatitis B vaccine had a severe allergic reaction, called anaphylaxis which caused difficulty breathing, dizziness, and skin rashes for a few people.
I would say A because there are different things in our economy that effect our gas prices. Therefore, it’s a cause and effect situation.
