A physicist working in a large laboratory has found that light particles traveling in a particle accelerator increase velocity in a manner that can be described by the linear function −4x + 3y = 21, where x is time and y is velocity in kilometers per hour. Use this function to determine when a certain particle will reach 40km/hr.

The particle will reach 40km/hr when x =

Answers

Answer 1

Answer:

Velocity of particle (y) = 40km/hr Rearrange equation to be 4x = 3y-21 Therefore 4x = 3*40-21 = 99 x = 99/4 = 24.75 hours

Would you recommend dancing as an activity done at home especially when most people stay at home, why or why not?

Answers

Answer:

Explanation:

Yes because dancing is something the whole family can do. Dancing can also help keep the family from getting bored and they might even learn something new. Something else to consider is that dancing is good for your health and body to.

My answer to the prompt is;

No. I will not recommend dancing as an activity done at home especially when most people stay at home.

Being considerate and empathetic to the needs of others is a major reason why I will not recommend dancing as an activity to be done at home.

At home, different people with differing needs can be found. There might be old people who just want to sleep and rest. There might also be young ones trying to study at home.

Dancing in such an environment will be distracting. A better place for such an activity is the Gym.

Pierre correctly simplified an expression. When he substituted x = 2 into the simplified expression, the value was 20. Which could be Pierre’s original expression?

Answers

Answer:

a) 2(7x-4)

Explanation:

Let us first simplify these expressions by multiplying them:

a) 2(7x-4) = 14x-8

b) 2(x-19) = 2x-38

c) 2(x+10) = 2x+20

d) 2(5x+1) = 10x+2

Now, we just plug in x=2 into these simplified expressions:

a) 14x-8 = 28-8 = 20

b) 2x-38 = 4-38 = -34

c) 2x+20 = 4+20 = 24

d) 10x+2 = 20+2 = 22

Now, we see that the original expression was 2(7x-4).

The graph indicates pH on the x-axis with a numbered line increasing to the left. The graph also indicates the rate of enzyme action as it increases on the Y-axis. A line starts at approximately 4.5 on the x-axis and climbs to a steep peak at approximately 9 on the x-axis. The line then declines at the same rate and levels out to its starting position at approximately 13 on the x-axis. There is a specific pH range in which the enzyme effectively lowers the reaction's activation energy. Increasing the pH makes it easier for the enzyme to lower the activation energy of the target reaction. As the pH increases, the activity of the enzyme to lower reaction activation energy is decreased. The enzyme will not assist the chemical reaction at a pH that is below 6 or above 12.
