Mathematics
1 answer:
Sophie [7]3 years ago
3 0

Answer:

Option A

Step-by-step explanation:

Number of components assembled by the new employee per day,

N(t) = \frac{50t}{t+4}

Number of components assembled by the experienced employee per day,

E(t) = \frac{70t}{t+3}

Difference in number of components assembled per day by experienced ane new employee

D(t)= E(t) - N(t)

D(t) = \frac{70t}{t+3}-\frac{50t}{t+4}

      = \frac{70t(t+4)-50t(t+3)}{(t+3)(t+4)}

      = \frac{70t^2+280t-50t^2-150t}{(t+3)(t+4)}

      = \frac{20t^2+130t}{(t+3)(t+4)}

      = \frac{10t(2t+13)}{(t+4)(t+3)}

Therefore, Option A will be the answer.

Name.<br> Solve using <br> Substitution <br> L<br> y = 3x + 2<br> 6x - 2y = 8
masya89 [10]

Answer:

No solution

Step-by-step explanation:

There is no solution to the system of equations y=3x+2 and 6x-2y=8, meaning that they are parallel to each other on a graph, with no points ever intersecting on each other's lines.

jason runs 440 yards in 75 seconds.At this rate how many minutes does it take him to run a mile? (1 mile = 1,760 yards)​
Zepler [3.9K]

Answer: 5 minutes

Step-by-step explanation:

We know that 1760 yards are in a mile. We can convert the given info into a proportion. 440/75 = 1760/x, where x is the number of seconds it takes to run a mile. Cross-multiply to get 440x = 75*1760. Divide both sides by 440 to get x = 75*4 = 300 seconds. The problem asks for how many minutes so you have to convert 300 seconds to minutes. To do this, we have to divide 300 by 60 to get 5 minutes.

URGENT. Which is an exponential decay function? ANSWER GETS BRAINLIEST.
Leno4ka [110]

Answer:

C

Step-by-step explanation:

For the first one, there is a ratio of change greater than one so that is exponential growth.

The second one has exponential decay but its x is negative making it actually exponential decay even if graphed.

The third one has positive growth over an interval of negative x, so in terms of  x there is exponential decay.

The fourth one is neither and if graphed is just points as there is a specific solution set.

In conclusion, the third is exponential decay!

Hope this helps :)
