Mathematics
1 answer:
Crank3 years ago
6 0

Answer and fdaStep-by-step explanation:::

The answer depends on the numbers that are inputted for a and b.

If the numbers that are inputted for both a and b are rational, then a + b would be rational.

If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.

If one of the variables is rational and the other is irrational, then a + b would be irrational.

In parallelogram EFGH, EJ = 6x + 3 and JG = 10x - 5 What is EG?<br>A: 15<br>B: 12<br>C: 25<br>D: 30​
Ne4ueva [31]

Answer:

  • D. 30

Step-by-step explanation:

It seems J is the intersection of diagonals.

We know diagonals of the parallelogram bisect each other.

<u>It gives us:</u>

  • EG = EJ + JG and
  • EJ  = JG

<u>Substitute and solve for x:</u>

  • 6x + 3 = 10x - 5
  • 10x - 6x = 3 + 5
  • 4x = 8
  • x = 2

<u>Find the value of EJ:</u>

  • EJ = 6*2 + 3 = 15

<u>Find the value of EG:</u>

  • EG = 2*EJ = 2*15 = 30

Correct choice is D

An object, which is at the origin at time t=0, has initial velocity V0= (-14.0i - 7.0j)m/s and constant acceleration a=(6.0i + 3
sesenic [268]
I am pretty sure the first thing we should do is to <span>integrate acceleration into velocity
And we will have: </span>a(t) = \ \textless \ 6,3\ \textgreater \v(t) = \ \textless \ (6t+C),(3t+C)\ \textgreater \ ; where    -- v(0) = \ \textless \ -14,-7\ \textgreater \
Then calculate v :&#10;v(t) = \ \textless \ (6t-14),(3t-7)\ \textgreater \
As you can see, velocity is zero and none of the objects is moving. It happens when <span> t=7/3 which means we can calculate this in the way we did (integrating) :
</span>p(t) = \ \textless \  (3t^2-14t+C) , ((3/2)t^2-7t+C) \ \textgreater \ &#10;
The product is <span>p(0) = 0 that makes us to reduce vector function to</span>p(t) = \ \textless \  (3t^2-14t) , ((3/2)t^2-7t) \ \textgreater \   where t = 7/3p(7/3) = \ \textless \  -49/3 , -49/6 \ \textgreater \<span>

</span>
