The formula tells you
.. V = constant * T/P
That is, volume is proportional to absolute temperature and inversely proportional to pressure.
When temperature increases from 273 K to 300 K, volume is increased by the factor 300/273.

When pressure increases from 2 atm to 3 atm, volume is changed by the factor 2/3.

The new volume will be
.. (10 L) * (300/273) * (2/3) = 2000/273 L ≈ 7.3 L

Find the sum of the arithmetic series given ai = 45, an = 85, and n = 5.

seraphim [82]

Answer:

C. 325.

Step-by-step explanation:

The last term a5 = 85

a1 = 45

Sum of n terms = n/2 (a1 + l)

So here we have n = 5, a1 = 45 and the last term l = 85

= (5/2)(45 + 85)

= 5/2 * 130

= 325.

Can someone answer this question please?

Slav-nsk [51]

Answer:

Therefore,

(x , y) YES / NO

(-4, -5) Yes, It is a Solution.

(1 , - 3) No, not a Solution.

(9 , 6) No, not a Solution.

(-6 , 2) No, not a Solution.

Step-by-step explanation:

Given:

$4x-7y=19$

To Determine:

Given ordered pair is a solution or not ?

Solution:

For (-4,-5)

Substitute x = -4 and y = -5 in above equation

Left Hand Side = 4 × (-4) - 7 × (-5)

= -16+35

= 19

Right Hand Side = 19

Left Hand Side = Right Hand Side

Satisfied

Hence (-4, -5) is the SOLUTION to 4x - 7y =19 (YES)

For (1, -3)

Substitute x = 1 and y = -3 in above equation

Left Hand Side = 4 × (1) - 7 × (-3)

= 25

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (1, -3) is NOT the Solution to 4x - 7y =19 (NO)

For (9, 6)

Substitute x = 9 and y = 6 in above equation

Left Hand Side = 4 × (9) - 7 × (6)

= -6

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (9, 6) is NOT the Solution to 4x - 7y =19 (NO)

For (-6, 2)

Substitute x = -6 and y = 2 in above equation

Left Hand Side = 4 × (-6) - 7 × (2)

= -38

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (-6, 2) is NOT the Solution to 4x - 7y =19 (NO)

Therefore,

(x , y) YES / NO

(-4, -5) Yes, It is a Solution.

(1 , - 3) No, not a Solution.

(9 , 6) No, not a Solution.

(-6 , 2) No, not a Solution.

Set Question involving real and natural numbers

Allushta [10]

Only two real numbers satisfy x² = 23, so A is the set {-√23, √23}. B is the set of all non-negative real numbers. Then you can write the intersection in various ways, like

(i) A ∩ B = {√23} = {x ∈ R | x = √23} = {x ∈ R | x² = 23 and x > 0}

√23 is positive and so is already contained in B, so the union with A adds -√23 to the set B. Then

(ii) A U B = {-√23} U B = {x ∈ R | (x² = 23 and x < 0) or x ≥ 0}

A - B is the complement of B in A; that is, all elements of A not belonging to B. This means we remove √23 from A, so that

(iii) A - B = {-√23} = {x ∈ R | x² = 23 and x < 0}

I'm not entirely sure what you mean by "for µ = R" - possibly µ is used to mean "universal set"? If so, then

(iv.a) Aᶜ = {x ∈ R | x² ≠ 23} and Bᶜ = {x ∈ R | x < 0}.

N is a subset of B, so

(iv.b) N - B = N = {1, 2, 3, ...}
