The power P of a jet of water is jointly proportional to the cross sectional area A and to the cube ofthe velocity V. (a) Write

anastassius [24]

Answer:

a) $P=kAV^3$

b) 54

Step-by-step explanation:

If one quantity, A, is jointly proportional to other 2 quantities (B & C), we can write proportionality equation as:

$A=k*B*C$

Where

k is the proportionality constant

Now, for this problem, P is jointly proportional to A and CUBE OF V, so we can write:

$P=kAV^3$

Now velocity, V, is triples, which means it becomes 3V

Also, cross sectional area, A, is doubled, which means it becomes 2A

Let's put these into formula and see the difference:

$P=kAV^3\\P=k(2A)(3V)^3\\P=k(2A)(27V^3)\\P=(2*27)kAV^3\\P=54kAV^3$

So, power is multiplied by a factor of 54. Power becomes 54 times if Area is doubled and velocity is tripled ( as seen ).

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the

harina [27]

Answer:

The missing statement is Corresponding angles theorem

Step-by-step explanation:

In this question we are finding the reason for the statement ∠6 ≅ ∠2.

We will write the statements and then we'll give their reasons.

Statement Reason

1) a || b, is a transversal Given

2) ∠6 ≅ ∠2 Corresponding angles theorem

3) m∠6 = m∠2 def. of congruent

4) ∠6 is supp. to ∠8 def. of linear pair

5) ∠2 is supp. to ∠8 congruent supplements theorem

Corresponding Angles Theorem states: If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

The angles in matching corners are called Corresponding Angles.We can further define it as corresponding angles are angles that are in the same relative position at an intersection of a transversal and at least two lines. If the two lines are parallel then the corresponding angles are congruent

Thus the missing statement is Corresponding Angles Theorem.
