The product of the expression (x-√7-3√8)(x√7-3√8) can be simplified as option B. 7x^2-12x√14+72

An identity equation is an equation that holds true for all values of the variable(s) involved. In other words, an identity equation is an equation that is always true, regardless of the values of the variables.

Given that (x-√7-3√8)(x√7-3√8), Using the identity equation which can be expressed as :  (a-b)² = a² +b² -2ab, we can aplly this as;

[(x√7-3√8)(x√7-3√8)] = [(x√7-3√8)² ]= [(x√7)²+(3√8)² -2(x√7)(3√8)]

   =[7x²+72 -6x√56]

   = [7x²+72-6x√(14×4)]

 =[ 7x²+72-12x√(14)]

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

Kiran is collecting dimes and quarters in a jar. He has collected $10.00 so far and has dimes and quarters. The relationship between the numbers of dimes and quarters and the amount of money in dollars is represented by the equation 0.1d +0.25q = 10.

If the number of dimes is 10, then the number of quarters will be

0.1 x 10 + 0.25q = 10

q = 36

If the number of dimes is 40, then the number of quarters will be

0.1 x 40 + 0.25q = 10

q = 24

If the number of dimes is 80, then the number of quarters will be

Answer:

The triangles are similar.

Step-by-step explanation:

The reason for this is because they both share two pairs of angles that are the same: 40 degrees and 60 degrees. If these are equal, then that must mean the third angle for both triangles is also the same, making both triangles equal in proportion. Therefore, they must be similar.

To find the zeros, you want to first factor the expression.

x³+x²-36

(x-3)(x²+4x+12)

Now that we have found the factors, we set each to 0.

x-3=0

x=3

Since x²+4x+12 cannot be factored, we can forget about this part.

Therefore, the zeros are x=3. You can check this by plugging the expression into a graphing calculator to see the zeros.

Answer

Angle 5 = 121º

Angle 7 = 121º

Explanation

To answer this, we need to explain what Same side interior angles and vertically opposite angles are.

Same side interior angles occupy the interior side of where the transversal line crosses the two stright lines. If the two lines are parallel to each other, then the sum of same side interior angles is equal to 180 degrees.

Vertical angles (or vertically opposite angles) are angles that are directly opposite each other at a point where two straight lines intersect. Vertical angles are equal to each other.

From the diagram, we can see that Angle 2 is vertically opposite to Angle 4. Hence,

Angle 2 = Angle 4 = 59º (vertically opposite angles)

Then, we can see that Angle 4 and Angle 5 are same side interior angles. Hence,

Angle 4 + Angle 5 = 180º (Same side interior angles)

59º + Angle 5 = 180º

Angle 5 = 180º - 59º

Angle 5 = 121º

We can then further see that Angle 5 is vertically opposite to Angle 7. Hence,

Angle 5 = Angle 7 = 121º (vertically opposite angles)

According to the quantity theory of money, changes in the money supply will lead directly to changes in the price level if velocity and real GDP are unaffected by the change in the money supply.Velocity can change over time, and changes in velocity may be caused by various factors.

For example, changes in velocity can be caused by shifts in payment practices, changes in the use of credit, changes in the availability of bank deposits or cash, or shifts in demand patterns.Changes in velocity may be related to changes in the money supply.

For example, if the money supply increases, the demand for money may increase, causing the velocity of money to decrease. Conversely, if the money supply decreases, the demand for money may decrease, causing the velocity of money to increase.

The defining statement from the problem is given as follows:

He finds that the temperature changed by -0.6°F.

The change by the negative amount of -0.6ºF means that the current temperature of the water is obtained subtracting the previous temperature of the water by 0.6 ºF.

The previous temperature of the water is given as follows:

72.3°F.

Hence the current temperature of the water is obtained subtracting 72.3ºF and 0.6ºF, as follows:

The 90% confidence interval for the population proportion of adults who believe in UFOs is (0.309, 0.339).

C. With 90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.

To construct a 90% confidence interval for the population proportion of adults who believe in UFOs, we can use the formula:

Confidence Interval = Sample Proportion ± Margin of Error

First, we calculate the sample proportion:

Sample Proportion \(\hat{p}\) = Number of adults who believe in UFOs / Total number of adults surveyed = 736 / 2266 ≈ 0.324

Next, we need to calculate the margin of error.

Since we are dealing with a large sample size, we can use the formula for a 90% confidence interval:

Margin of Error\(= Z \times \sqrt{(\hat{p} \times (1 - \hat{p}) / n)}\)

Here, Z represents the z-value for a 90% confidence level, which corresponds to a z-value of 1.645. n represents the sample size.

Margin of Error\(= 1.645 \times \sqrt{(0.324 \times (1 - 0.324) / 2266)}\) ≈ 0.015

Finally, we can construct the confidence interval:

Confidence Interval = 0.324 ± 0.015 = (0.309, 0.339)

Therefore, the 90% confidence interval for the population proportion of adults who believe in UFOs is (0.309, 0.339).

Now, let's interpret the results.

The correct answer is:

C. With 90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval.

This means that we are 90% confident that the true proportion of adults who believe in UFOs falls within the range of 0.309 to 0.339.

I can't see it what is it .........................

Answer:

Step-by-step explanation:

3\(x^{3}\)\((2y)^{2}\)4\(x^{4}\)

So I wrote down exactly above how the eq. is put in the question, note that the 2y is the only coefficient that is inside of the parenthesis,  I hope that is how the question is asked.  The 3 and 4 coefficient are NOT part of the exponential part.. is my point.. which will make a big difference if they were.  

anyway

3\(x^{3}\)4\(y^{2}\)4\(x^{4}\)

48\(y^{2}\)\(x^{3}\)\(x^{4}\)    ( b/c the x bases are the same we can just add the exponents)

48\(y^{2}\)\(x^{3+4}\)

48\(y^{2}\)\(x^{7}\)   ( this is your answer )

side note: an important learning point that was implied above is that you could rewrite the expression as 48\(y^{2}\)\(x^{2}\)\(x^{2}\)\(x^{2}\)\(x^{1}\)... why would you want to write it that way?  b/c often a square is needed to make a problem work out easier.
