The inverse for f(x) = 12 - x is f^-1(x) = -x + 12

Define Inverse Function

An inverse function or an anti function is defined as a function, which can reverse into another function.

The given equation is ,

f(x) = 12 - x

We can also write like this,

y = 12 - x

Now, for the inverse just swap x and y like this

x = 12 - y

x - 12 = - y

y = -x + 12

Now, we know

y = f^-1(x) = -x + 12

Hence, f^-1(x) = -x + 12

The final velocity of student B is -1.05 m/s. This value is negative, indicating that student B is moving to the left after the collision.

What is Velocity?

Velocity is a term that describes the speed and direction of a point's motion.

Conservation of momentum states that the total momentum of a system remains constant unless acted upon by an external force. In this case, the two students can be considered a closed system, since no external forces are acting on them.

Therefore, the total momentum of the system before the collision must be equal to the total momentum of the system after the collision.

We can represent the momentum of each student as a vector, where the magnitude is equal to the mass of the student times their velocity and the direction is the direction in which the student is moving. The total momentum of the system before the collision can be found by adding the individual momenta of the two students:

Momentum before collision = (62 kg * 3.80 m/s) + (67 kg * -2.59 m/s)

= 233.6 kg m/s + (-174.53 kg m/s)

= 59.07 kg m/s

After the collision, student A bounces backwards at 1.17 m/s, while student B moves with an unknown velocity in the opposite direction. We can represent the total momentum of the system after the collision as:

Momentum after collision = (62 kg * -1.17 m/s) + (67 kg * v)

where v is the velocity of student B after the collision. We can set the two expressions for total momentum equal to each other and solve for v:

59.07 kg m/s = (62 kg * -1.17 m/s) + (67 kg * v)

v = (59.07 kg m/s + 62 kg * -1.17 m/s) / 67 kg

= (-70.34 kg m/s) / 67 kg

= -1.05 m/s

Therefore, The final velocity of student B is -1.05 m/s. This value is negative, indicating that student B is moving to the left after the collision.

Answer:

7.3%

Step-by-step explanation:

Cost for 50 glasses = ₹1500 -----> Cost Price (C.P)

Cost per glass = 1500/50 = ₹30

Here, 4 glasses break. So, she now has

50-4 = 46 glasses

She sold 46 glasses for ₹35 each,

Money earned = 46x35 = ₹1610 -----> Selling Price (S.P)

Since S.P > C.P,

she made a profit = 1610-1500 = ₹110

Profit% = Profit/Cost Price x 100

= 110/1500 x 100

From the various triangle proofs below, we have been able to show that; 3A F = AC

A median of a triangle is defined as a line segment from a vertex of the triangle to the midpoint of the side opposite that vertex.

We are given that;

AD is the median of ΔABC.

E is the midpoint of AD

Through D, we draw DG parallel to BF

In ΔADG, E is the midpoint of AD and EF is parallel to DG

By using the converse of midpoint theorem, we have;

F is midpoint of AG and A F = FG     ------(eq 1)

Likewise, In ΔBCF ;

D is the midpoint of BC and DG is parallel to BF  

G is midpoint of CF and FG is congruent to GC (FG ≅ GC) .........(eq 2)

The markup from cost to sale price was originally 245%.

The markup is the addition put on the cost of an item.

Goods are marked-up to take care of other selling and administrative costs and to achieve an estimated profit.

The cost of the item plus the markup equals the retail selling price.

Selling price = $720

Markdown percentage = 30%

Marked-up selling price before the markdown = $1,029 ($720/0.7)

Markup cost = $420

Markup difference = $609 ($1,029 - $420)

Markup = 245% ($1,029/$420 x 100)

Step-by-step explanation:

The equation of the line passes through the point (6,2) and slope 1/3 is

X=3Y-3

Here the point is (6,2) and the slope is 1/3

Means,

x=6      y=2   and m=1/3

We know that the equation of a line is -

Y=mx+c

Putting these values in the above equation we get

⇒2=1/3×6+c

⇒2=6/3+c

⇒2=2+c

⇒c=1

Therefore we find that the intercept is 1

So after putting all these values in that equation y=mx+c we get

Demoivre's theorem states that for all complex numbers z and all positive integers n:

z^n = (r^n) × (cos(n∅) + isin(n×∅))

where r is the magnitude of z and theta is the argument of z.

To use Demoivre's theorem to simplify (1−i)^12, we can first write (1−i) in polar form as r × cis(∅). where r is the magnitude and cis(∅) is the size complex number. is 1, the argument ∅. In this case the size of (1−i) is √(1^2 + (-1)^2) = √(2) and the argument of (1−i) can be found using the arctangent function.

∅ = arctan(-1÷1) = -45 degrees.

So (1−i) can be written as sqrt(2) × cis(-45 degrees). Applying this to Demoivre's theorem, we get:

(1−i)^12 = (√(2)^12) × (cos(-540°) + i×sin(-540°))

We can simplify this to:

(1−i)^12 = 2^6 × cis(-180°)

This can be further simplified as follows.

(1−i)^12 = 64 × (-1)

Answer:four eighth notes

Step-by-step explanation:

The expected value of x for the awarded 3 points for each coin that lands with heads faceup is 27/8.

In this instance, we are informed that:

The probability of each of them is calculated as:

Situation 1: No heads

That implies that all three coins must land on the tail.

Thus, there is only one method to accomplish this. While the whole range of potential outcomes is;

= 2x 2x 2

= 8

via the product rule (because each coin has two alternative outcomes).

The result is:

P(x =0) = 1/8

Situation 2: One head

Single head means three points, or X = three.

Total outcomes possible = 8,

Single head can occur in 3 different ways, as other two needs to be strictly tails.

Thus,

P(x = 3) = 2/8

Situation 3: Two heads

Two heads equals 3+3 = 6.

X = 6

8 outcomes are possible in total.

Single tail means two heads. Three separate scenarios can lead to a single tail.

Therefore,

P(x = 6) = 2/8

Situation 4: Three heads

Three heads signifies that X = 9 or 3+3+3 = 9 points.

8 outcomes are possible in total.

Three heads means there is only one way to do it and no tail.

Thus,

P(x = 9) = 1/8

As a result, the expectation of X is determined as follows:

E(x) = 0. 1/8 + 3. 2/8 + 6. 2/8 + 9. 1/8

E(x) = 27/8

Therefore, 27/8 is the expected value of X.

Interest is the amount to be paid on the borrowed money or the amount received on the money lent.

Given that, Susan made a one-time deposit of $2,500 in an investment account. She earned 4.25% interest for 10 years.

SI = PxRxT/100

P = principal = $2500

R = interest rate = 4.25%

T = time = 10 years

SI = 2500x10x4.25/100

What is test statistics ?

In statistical hypothesis testing, a test statistic is a statistic that is employed. A hypothesis test is often defined in terms of a test statistic, which is a numerical summary of a data set that can be used to execute the test and reduces the data to one value.

Here,

According to a report on the evening news show, burglaries occurred in 23 out of 197 residences without pets and 10 out of 129 homes with pets.

Let p1 represent the percentage of dog-owning homes who experienced burglaries.

p2 is the population proportion of burglarized homes without canine companions.

Since both population proportions are equal, the null hypothesis (H) is that p1=p2.

A Different Hypothesis, K:p1≠p2 indicates that there is an imbalance between the two population proportions.

The test results that would be utilized in this z-test for proportions with two samples;

                          T.S. = [tex]\frac{(p1^{'} -p2^{'} )-(p1-p2)}{\sqrt{\frac{p1^{'}1-p1^{'}()}{n1} +\frac{p2^{'}(1-p2^{'})}{n2} } }[/tex]~ N(0,1)

where,  p1= sample proportion of households with pet dogs who were burglarized =10/105  = 0.095

p2= sample proportion of households without pet dogs who were burglarized = 24/212 = 0.11

n1= sample of households with pet dogs = 105

n2 = sample of households without pet dogs = 212

So, the test statistics  =  [tex]\frac{(0.0095 -0.11 )-(0)}{\sqrt{\frac{0.095(1-0.095)}{105} +\frac{0.11(1-0.11)}{212} } }[/tex]

                                                                      =  -0.487
