Answer:

The general form of a quadratic equation is ax^2 + bx + c = y.  From the equation for c, our a is -2, our b is -7 and our c is 5.  

When a < 0, the function opens downward and has a maximum for its vertex.

When a quadratic function has maximum, its x values will always be increasing from negative infinity to the x-coordinate of the maximum (You can also simply write x < x coordinate of the maximum as you've already done).

We can find the x-coordinate of the maximum using the equation

[tex]-b/2a[/tex]

Thus, since b is -7 and a is -2, we have

[tex]-(-7)/2(-2)\\7/-4\\-7/4=-1.75[/tex]

This is how you get that the function is increasing from x < -1.75.

The green line in the attached picture also highlights the same idea.

It is important to check that the number of successes and number of failures in each sample is at least 10 because this helps ensure that the normal approximation of the binomial distribution is accurate.

When constructing a confidence interval for the difference between two population proportions, it is important to check that the number of successes and the number of failures in each sample is at least 10 because this helps ensure that the normal approximation of the binomial distribution is accurate. The normal approximation is often used in constructing confidence intervals for proportions because it simplifies the calculations, but it is only accurate if the sample size is large enough.

A common rule of thumb is that each sample should have at least 10 successes and 10 failures in order to ensure that the normal approximation is reasonable. This is because the Central Limit Theorem states that the sum of many independent and identically distributed random variables will approximately follow a normal distribution. When the sample size is large enough, the distribution of the sample proportions will be approximately normal, even if the individual observations are not.

If the number of successes and failures in each sample is less.

Show A is 90 minutes long, and Show B is 45 minutes long.

Let's say Show A is x minutes long. Then Show B is x/2 minutes long since Show A is twice as long as Show B. The total duration of Show A and Show B is 2 hours and 15 minutes, or 135 minutes.

So, x + x/2 = 135

Multiplying both sides by 2, we get 2x + x = 270

Combining like terms, we get 3x = 270

Dividing both sides by 3, we get x = 90

When we want to find all the points on a surface where the tangent plane is horizontal, we are essentially looking for the points where the surface has a horizontal slope. The points on the surface where the tangent plane is horizontal are the points (0, 0, 0).

To find these points, we can use the partial derivative test. First, we calculate the partial derivatives of the surface function with respect to x and y, and set them equal to zero. These equations will give us the x and y values of the points where the slope is zero.

Next, we plug these values back into the original surface function to obtain the z-coordinate of the points. These are the points on the surface where the tangent plane is horizontal.

For example, let's consider the surface function z = x^2 + y^2. To find the points on this surface where the tangent plane is horizontal, we need to find the x and y values where the partial derivatives of z with respect to x and y are equal to zero.

Taking the partial derivative of z with respect to x, we get:

∂z/∂x = 2x

Setting this equal to zero, we get: 2x = 0

Solving for x, we get x = 0.

Taking the partial derivative of z with respect to y, we get:

∂z/∂y = 2y

Setting this equal to zero, we get: 2y = 0

Solving for y, we get y = 0.

Therefore, the points on the surface where the tangent plane is horizontal are the points (0, 0, 0).

In summary, when we want to find all the points on a surface where the tangent plane is horizontal, we can use the partial derivative test and set the partial derivatives of the surface function with respect to x and y equal to zero. We can then plug these values back into the original surface function to obtain the z-coordinate of the points.

Answer:

Step-by-step explanation:

Given, the sides of triangle ABC are 12, 16 and 20, which form a right triangle (as 20 is the hypotenuse).

Let us assume that the sides of triangle XYZ are x, y and 24 (XZ=24).

Since ABC ~ XYZ, we can use ratios of corresponding sides to find the lengths of the sides of triangle XYZ:

x/12 = y/16 = 24/20

Solving for x and y, we get:

x = 9 and y = 12

So, the perimeter of triangle AXYZ = 9 + 12 + 12 + 24 = 57.

The coordinates of R are (2,3) which represents an intersecting point of the given lines.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

The lines are given in the question, as follows:

y = x+1 ...(i)

x+2y = 8  ...(ii)

Since both lines intersect at R.

Substitute the value of equation (i), in (ii), and we get

x+2(x+1) = 8

x + 2x + 2 = 8

3x = 8 - 2

3x = 6

x = 2

Substitute the value of x = 2 in equation (i),

y = 2 + 1

y = 3

The cost of a restricted pass is equals to £35 and the cost of a full pass is equals to £20.

We have, Brian and Bob visit a ski resort.

In case of Brain,

Number of full passes = 3

Number of restricted passes = 4

In case of Bob,

Number of full passes = 2

Number of restricted passes = 3

Let " £r" and " £p" be the cost of each full pass and restricted pass. Then, on basis of problem,

Total cost of passes in case of brain = £185

=> 3p + 4r = 185 --(1)

Similarly, Total cost of passes in case of bob

= £130

=> 2p + 3r = 130 --(2)

Now, equation (1) and (2) formed a system of two linear equations. We have to calculate the value of "r" and "p" . So, using the Elimination method,

Multiplying the equation (1) and equation (2) by 2 and 3 respectively and then equation (2) from (1) to eliminate the variable "p".

=> 2(3p + 4r) - 3(2p + 3r) = 2× 185 - 3× 130

=> 6p + 8r - 6p - 9r = 370 - 390

=> -r = - 20

=> r = 20

then from equation (1) , 3p + 4(20) = 185

=> 3p = 185 - 80 = 105

=> p = 105/3 = 35

Hence, the required values of r = £20 and p = £35.

The difference between the sample standard deviation (s) and the population standard deviation (σ) will generally be greater for the data set with fewer data values.

This is because the sample standard deviation is an estimate of the population standard deviation, and with a smaller sample size, the estimate is likely to be less accurate.
In this case, the data set with 20 data values has a smaller sample size, so the difference between s and σ will be greater for this data set compared to the data set with 50 data values. The larger the sample size, the more representative the sample is of the population and the more accurate the estimate of the population standard deviation is likely to be.
It's worth noting that while the sample standard deviation is a useful measure of variability in the sample, it is not the same as the population standard deviation, which is a true measure of the variability in the population. The sample standard deviation can be used to make inferences about the population standard deviation, but it is important to consider the sample size and other factors that may affect the accuracy of the estimate

Only matrices of the same size can be added or subtracted.

A matrix is a rectangular array of numbers and is composed of rows and columns. In order to add or subtract matrices, the matrices must have the same number of rows and columns. If the matrices do not have the same size, they cannot be added or subtracted.

For example, if one matrix is a 2x3 matrix, the other matrix must also be a 2x3 matrix. Similarly, if one matrix is a 3x2 matrix, the other matrix must also be a 3x2 matrix. The numbers in each matrix may vary, but the size of the matrices must be the same for the operation to be valid.

When adding or subtracting matrices, the numbers in the same position (row and column) are added or subtracted. For example, if one matrix is [[1,2,3], [4,5,6], [7,8,9]] and the other matrix is [[2,4,6], [8,10,12], [14,16,18]], the resulting matrix would be [[3,6,9], [12,15,18], [21,24,27]].

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Given is a parallelogram as shown in the image.

Opposite angles of a parallelogram are equal. So, we can write -

x + 50 = y

y - x = 50                                                                  .... Eq { 1 }

Sum of the angles of a quadrilateral are 360°. We can write -

2x - 60 + x + 50 + y = 360

3x + y = 370

You want to know the operation that will give a binomial result from the expressions (3y^6 +4) and (9y^12 -12y^6 +16).

The like terms in the two expressions are 3y^6 and -12y^6, or +4 and +16. Combining these terms by addition or subtraction will not result in the elimination of either the y^6 term or the constant term. Hence addition or subtraction cannot result in a binomial.

We know that the sum of cubes is factored into the product of a binomial and a trinomial:

  a³ +b³ = (a +b)(a² -ab +b²)

Comparing this form to the given binomial and trinomial, we see that we can choose ...

  a = 3y^6

  b = 4

to make the given factors match exactly. That tells us their product will be a binomial sum:

Answer:

12 houses

Step-by-step explanation:

First you need to figure out how many were sold the first month. You need to figure out how much 1/3 of 48 is, so you need to divide 48 by 3, equaling 16. You then multiply 16 by two, because they didnt sell 1/3, but 2/3. 16 times 2 is 32, so 32 houses were sold in the first month, by doing 48-32, you can say that there were 16 houses left to sell. Then if 1/4 of those houses were sold the next month, then you need to figure out what 1/4 of 16 is. In the same way as before, you divide 16 by 4, which equals 4. If they sold 4 of 16 the next month, you then need to subtract 16 by 4, equaling 12. This means there are 12 houses remaining to be sold.
