Translate left 12 units, stretch by a factor of 4, and reflect over the x-axis. Then state the vertex. g(x)= vertex:

Using the transformation concepts, it is found that:

   The rule for g is: [tex]g(x) = -4x^{2}[/tex]

   The vertex is: (0,0).

   Stretching a function f(x) vertically by a factor of b is given by:

[tex]g(x) - bf(x)[/tex]

   Reflecting a function over the x-axis is the equivalent of:

g(x) = -f(x)

   The original function is: [tex]f(x) = x^{2}[/tex]

   Stretching by a factor of 4 means that the function is multiplied by 4, thus: [tex]g(x) = 4x^{2}[/tex]

   Reflecting over the x-axis, that is, multiplying by -1, we have that: [tex]g(x) = -4x^{2}[/tex], which is the rule for g.

   From the above equation, added at the end of this answer, the vertex is at (0,0).

Hence the answer is the vertex is at (0,0)

Step-by-step explanation:

The density of the drink is approximately 1.04 g/cm³.

Density is the ratio of mass and volume.

density = mass/volume

To work out the density of the drink, you will need to calculate the total mass of the drink and then divide it by the volume of the drink.

First, you can calculate the mass of the grape juice by multiplying the density of grape juice by the volume of grape juice:

Mass of grape juice = Density of grape juice x Volume of grape juice

= 1.07 g/cm³ * 35 cm³

= 37.45 grams

Then, you can calculate the mass of the fruit syrup in the same way:

Mass of fruit syrup = Density of fruit syrup x Volume of fruit syrup

= 1.6 g/cm³ x 25 cm³

= 40 grams

Finally, you can calculate the mass of the carbonated water in the same way:

Mass of carbonated water = Density of carbonated water x Volume of carbonated water

= 0.99 g/cm³ * 310 cm³

= 308.9 grams

To find the total mass of the drink, you can add the mass of the grape juice, the mass of the fruit syrup, and the mass of the carbonated water:

Total mass of drink = 37.45 grams + 40 grams + 308.9 grams

= 386.35 grams

To find the density of the drink, you can divide the total mass of the drink by the volume of the drink:

The density of drink = Total mass of drink / Volume of drink

= 386.35 grams / 370 cm³

= 1.04 g/cm³

Therefore, the density of the drink is approximately 1.04 g/cm³.

The largest area that can be enclosed by a fence of 240 m and a wall is 7200m²

It is given that the rectangular area will be fenced up against a long rectangular wall. Therefore, the fencing will be done on just three sides.

Let one side be x

Then the side opposite to it must be x cm as well

The sum of the three sides should be equal to 240 m

Hence the third side must be 240 - 2x m

Therefore the area of the region fenced must be

A = x(240 - 2x)

or, A = 240x - 2x²

Now we need to maximize the above equation

Taking the first derivative zero we get

A' = 0

or, 240 - 4x = 0

or, 60 - x = 0

or, x = 60

Now we will test whether the above output is maximum or not. The second derivative of A is

A'' = -4

Since A'' is a constant function,

Now, A''(60) = -4

Therefore, the maximum side will have lengths of 60 m and 120 m.

Hence the largest area that can be enclosed with the fence is

60 X 120 m²

= 7200 m²

1 Quintal can be carried for Rs 180 to the same direction.

Given that the charge of 0.25 quintal to a certain distance is Rs 45.

With Rs 45, 0.25 quintals can be carried.

I would choose the western side to climb because it is less steep then others.

In mathematics, a line's steepness is determined by its slope (or gradient). The slope is the ratio of any two points on a line's vertical and horizontal distances. A line's steepness can be determined by looking at its slope. Slope is calculated mathematically as "rise over run" (change in y divided by change in x). The slope's absolute value serves as a gauge for a line's steepness, incline, or grade. A steeper line is indicated by a slope with a higher absolute value. A line can be drawn with one of four directions: upward, downward, horizontal, or vertical. If a line rises from left to right, it is said to be increasing.

Translation in the point is left 2 units, down 4 units.

so left- right translation is done on x-axis where moving left means subtracting is while up - down translation is done on y- axis where moving down means subtracting.

Which means 2 units will be subtracted from x-axis and 4 units from y-axis

The probability that a randomly selected sample mean will be more than $100 = 0.14082.

We are given that according to a research​ institution, the average hotel price in a certain year was $97.00.

Assume the population standard deviation is $18.00 and that a random sample of 40 hotels was selected.

Here, Mean = μ = $97.00  and  Standard deviation = σ = $18 and  n = 40

(a) Standard error of the mean = σ/[tex]\sqrt{n}[/tex] = 18/[tex]\sqrt{40}[/tex] = 2.74

(b) Let X bar = Sample Mean

The z score probability distribution for sample mean is ;

          Z = Xbar-μ/ σ/[tex]\sqrt{n}[/tex] ~ N(0,1)

So, Probability that the sample mean will be less than $102 = P(X bar < $102)

P(X bar < 102) = P(Xbar-μ/ σ/[tex]\sqrt{n}[/tex] < 102 - 97.00/ 18/[tex]\sqrt{40}[/tex]) = P(Z < 0.74) = 0.7704

(c) Probability that the sample mean will be more than $104 =P(X bar > $104)

=  P(X bar > 104) = P(Xbar-μ/ σ/[tex]\sqrt{n}[/tex] < 104 - 97.00/ 18/[tex]\sqrt{40}[/tex]) = P(Z > 1.47) = 1 - P(Z <= 1.47)

= 1 - 0.92922 = 0.0708

(d) Probability that the sample mean will be between $99 and $100 is given by = P($99 < X bar < $100) = P(X bar < $100) - P(X bar <= $99)

= P(X bar < 100) = P(Xbar-μ/ σ/[tex]\sqrt{n}[/tex] < 100 - 97.00/ 18/[tex]\sqrt{40}[/tex]) = P(Z < 0.01) = 0.50399

= P(X bar <= 99) = P(Xbar-μ/ σ/[tex]\sqrt{n}[/tex] <= 99 - 97.00/ 18/[tex]\sqrt{40}[/tex]) = P(Z <= -0.35) = 1 - P(Z <= 0.35)

= 1 - 0.63683 = 0.36317

Therefore, P($99 < X bar < $100) = 0.50399 - 0.36317 = 0.14082 .

Hence the answer is the probability that a randomly selected sample mean will be more than $100 = 0.14082.

Interest rate (quarterly)= r= 4%

Time= t = 2 years

Now, we will using the formula below:
