Answer:

Increase by 5 times

Step-by-step explanation:

Given that from the ideal gas law;

PV = nRT

P= pressure

V= volume

n= number of moles

R= gas constant

T = temperature

It the follows that;

V= nRT/P

When the number of moles (quantity of helium) is increased by a factor of 5 while temperature and pressure remain constant, we can write;

PV = 5nRT

V = 5nRT/P

Hence the volume increases by a factor of 5.

Answer:

The answer is A

Step-by-step explanation:

I got it right

Answer:

Answer is A

Step-by-step explanation:

Answer:

A. 25, obtuse

Step-by-step explanation:

By exterior angle theorem:

2x° = 30° + 20°

2x° = 50°

x° = 50°/2

x° = 25°

x = 25

Type of triangle: Obtuse

Given:

The equation of the parabola is

[tex]y=2x^2+8x+3[/tex]

To find:

The vertex and check whether it opens up or down.

Solution:

We have,

[tex]y=2x^2+8x+3[/tex]

Here, leading coefficient is 2 which is a positive number. So, the parabola opens up.

The vertex of parabola [tex]f(x)=ax^2+bx+c[/tex] is

[tex]\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)[/tex]

Here, a=2, b=8 and c=3.

[tex]\dfrac{-b}{2a}=\dfrac{-8}{2(2)}[/tex]

[tex]\dfrac{-b}{2a}=\dfrac{-8}{4}[/tex]

[tex]\dfrac{-b}{2a}=-2[/tex]

Putting x=-2 in the given equation.

[tex]y=2(-2)^2+8(-2)+3[/tex]

[tex]y=2(4)+(-16)+3[/tex]

[tex]y=8-16+3[/tex]

[tex]y=-5[/tex]

So, the vertex of the parabola is at (-2,-5) and parabola opens up.

Therefore, the correct option is D.

Step-by-step explanation:

The triangles are congruent due to Hypotenuse-Leg congruence. (HL congruence)

Each of the triangles have a right-angle, a congruent hypotenuse and a congruent side of the triangle.

Therefore Triangles ABC and PRQ are congruent.

The point on the polar coordinate that represents (-6, pi/12) is point C.

The point on the polar coordinate system that is equivalent to (-6, pi/12) is point C. This is the case because the value of pi/12 can be found on the cis formation to C.

In addition, multiplying the denominator by two gives us the value of 12. So, the point on this plane that is equal to  (-6, pi/12) is point C. The polar coordinate system is one of the many ways of representing a complex function.

Answer:

w=15a-5b+2

w+5b-2=15a

(w+5b-2)/15=a

Step-by-step explanation:

The value of a in the expression w = 5(3a - b) + 2 is a = (1 + 5b - 2)/15.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given an expression  w = 5(3a - b) + 2.

Now to make 'a' the subject is the same as finding the value of a.

w = 5(3a - b) + 2.

w = 15a - 5b + 2.

w + 5b - 2 = 15a.

a = (1 + 5b - 2)/15.

Answer:

The margin of error M.O.E = 2.5%

Step-by-step explanation:

Given that;

The sample size = 1500

The sample proportion [tex]\hat p[/tex] = 0.60

Confidencce interval = 0.95

The level of significance ∝ = 1 - C.I

= 1 - 0.95

= 0.05

The critical value:

[tex]Z_{\alpha/2} = Z_{0.05/2} \\ \\ Z_{0.025} = 1.96[/tex] (From the z tables)

The margin of error is calculated by using the formula:

[tex]M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1 -\hat p)}{n}}[/tex]

[tex]M.O.E = 1.96 \times \sqrt{\dfrac{\hat 0.60(1 -0.60)}{1500}}[/tex]

[tex]M.O.E = 1.96 \times \sqrt{\dfrac{0.24}{1500}}[/tex]

[tex]M.O.E = 1.96 \times \sqrt{1.6 \times 10^{-4}}[/tex]

M.O.E = 0.02479

M.O.E ≅ 0.025

The margin of error M.O.E = 2.5%
