A balloon containing 0.40 mol of a gas with a volume of 5.0 l was deflated to 1.0 l. which equation should you use to find the final number of moles of gas in the balloon after the deflation? v subscript 2 equals startfraction v subscript 1 n subscript 2 over n subscript 1 endfraction. n subscript 2 equals startfraction v subscript 2 n subscript 1 over v subscript 1 endfraction. n subscript 2 equals startfraction v subscript 1 n subscript 1 over v subscript 2 endfraction.

Answers

Answer 1

The equation he should you use to find the final number of moles of gas in the balloon after the deflation is n1/v1 = n2/v2

Molarity of a solution

The molarity of a solution is the ratio of the mole of the substance to its volume

Since the mole "n" is directy proportional to the volume, hence;

n = kv
k = n/v

Hence the equation he should you use to find the final number of moles of gas in the balloon after the deflation is n1/v1 = n2/v2

Find (f•g) (x) if f(x)=3x^2 and g(x)=5-x

Answers

Answer:

f(g(x))=3x^2-30x+75

Step-by-step explanation:

We want to find the value of f(x) when x is equal to g(x)

So we can substitute the value of g(x) into the f(x) equation

f(g(x))= 3(5-x)^2

f(g(x))= 3(25-10x+x^2)

f(g(x))=3x^2-30x+75

Answers

Answer:

x=10, z=106

Step-by-step explanation:

vertical angles: 10x-26=74

10x=100

x=10

supplementary angles: 74+z=180

z=106

x=10
z=106
EXPLAINED:
To get x you would need to set the equation like this (10x-26)=74 (since 74 and the equation with the variable are parallel), then solve normally for x.

To get z you would have to know that the straight line through it equals 180 degrees so you would simply subtract 74 for 180 and there you have it you have the value of z.

From the complete question, the probability that the spinner will not land on c when spun twice is:

P = 4/9

Using the complement rule, the probability that the spinner will land on c at least once is:

P' = 1 - P

This gives

P' = 1 - 4/9

Evaluate

P' = 5/9

Hence, the probability that the spinner will land on c at least once is 5/9

The average rate of change for the interval from x = 5 to x = 6 is - 22.

What is quadratic function?

A quadratic polynomial in mathematics is a polynomial of degree two in one or more variables. The polynomial function defined by a quadratic polynomial is known as a quadratic function.

Since, the quadratic function has a vertex at (1, 2),

Hence, the equation for the function can be written in vertex form as:

⇒ y = a(x - 1)² + 2

Where "a" is a constant that determines the shape of the parabola. To find the value of "a", we can use one of the other points on the parabola.

Let's use the point (2, 1):

1 = a(2 - 1)² + 3

1 = a + 3

a = - 2

So, the equation for the quadratic function is:

y = -2x² + 2

Now we can use this equation to find the average rate of change between x = 5 and x = 6. The value of the function at x = 5 is:

y = - 2 x 25 + 2 = - 48

The value of the function at x = 6 is:

y = -2 x 36 + 2 = - 70

The average rate of change between x = 5 and x = 6 is:

(y₂ - y₁) / (x₂ - x₁) = (- 70 - (-48)) / (6 - 1) = - 22

Therefore, the average rate of change for the interval from x = 5 to x = 6 is - 22

A series contains 18 numbers and has a sum of 4,185. the last number of the series is 275. what is the first number? 42.5 190.0 465.0 740.0

Answers

The first term of the series if the series contains 18 numbers and has a sum of 4,185 is 190

Sequence and series

Series are sum of sequences

The formula for calculating the last term of a sequence is expressed as:

Sn = n/2(a+l)

Given the following

Sn = 4185

n = 18

l = 275

Required

first term "a"

Substitute

4185 = 18/2(a + 275)

4185 = 9(a + 275)

465 = a+ 275
a = 465 - 275
a = 190

Hence the first term of the series if the series contains 18 numbers and has a sum of 4,185 is 190
