(3xy)^2 = (3xy)*(3xy) = (3*3)*(x*x)*(y*y) = 9x^2y^2

a right angle is 90°, or 1/4 of a circle.

3/5 * 1/4 = 3/20

radian measure is the length of the circumference of this part of the circle.

a full circumference of a circle would be 2*pi*r, also expressed as 2 rad * r

now let's multiply the full thing with the 3/20 from earlier to just get the desired fraction:

6/20 rad * r

= 3/10 rad * r

of course a solution in cm or inch still depends on the radius here, wich could be just plugged in at will

Answer:

\(\frac{3\pi }{10}\)

Step-by-step explanation:

To express degrees in radians

radian measure = degree measure × \(\frac{\pi }{180}\)

\(\frac{3}{5}\) of a right angle

= \(\frac{3}{5}\) × 90° = 54° , then

radian = 54 × \(\frac{\pi }{180}\) = \(\frac{54}{180}\) × π = \(\frac{3}{10}\) × π = \(\frac{3\pi }{10}\)

By the calculations below, there are 20 groups of 1/5 in 4.

To find out how many groups of 1/5 are in 4, we can use the concept of division of fractions.

Recall that dividing by a fraction is the same as multiplying by its reciprocal. So, we can rewrite the problem as:

4 ÷ 1/5

To find the reciprocal of 1/5, we flip the fraction:

1/5 → 5/1

Now, we can rewrite the division problem as multiplication:

4 ÷ 1/5 = 4 × 5/1

Multiplying across gives:

4 × 5/1 = 20

Therefore, there are 20 groups of 1/5 in 4.

Nicky has 98 photos and Daniel has 49 photos on his i-phone

Represent David with D and Nicky with N.

So, we have:

D + N = 147

D =0.5N

Substitute D =0.5N in D + N = 147

0.5N + N = 147

Evaluate the sum

1.5N = 147

Divide both sides by 1.5

N = 98

Substitute N = 98 in D =0.5N

D =0.5 * 98

Evaluate

D =49

Hence, Nicky has 98 photos and Daniel has 49

Ted can clear a football field in 3 hours, while Jacob can clear it in 2 hours. When they work together, the time it takes to clear the field can be determined by solving the equation 1/3 + 1/2 = 1/t.

Let's consider the equation 1/3 + 1/2 = 1/t, where t represents the number of hours it would take Ted and Jacob to clear the field together. To solve for t, we need to find a common denominator for the fractions on the left-hand side. The least common multiple (LCM) of 3 and 2 is 6.

By multiplying the first fraction by 2/2 and the second fraction by 3/3, we can rewrite the equation as (2/6) + (3/6) = 1/t. This simplifies to 5/6 = 1/t.

To isolate t, we can take the reciprocal of both sides, giving us t/1 = 6/5. Cross-multiplying, we find t = 6/5 = 1.2.

Therefore, it will take Ted and Jacob 1.2 hours (or 1 hour and 12 minutes) to clear the football field together.

Step-by-step explanation:

The amplitude of the graph of y = 4sin3(x - 2) is 4.  

The amplitude of a sine or cosine function is the absolute value of the coefficient in front of the sine or cosine term. The general form of a sinusoidal function is y = A sin(B(x - C)) + D, where A is the amplitude, B is the frequency, C is the phase shift, and D is the vertical shift. In the given function y = 4sin3(x - 2), the amplitude is 4, which is the coefficient of the sin function. Therefore, the amplitude of the graph is 4.

Thus, the amplitude of the graph of y = 4sin3(x - 2) is 4.

Step-by-step explanation:

Its in simplest form

a)  P(X=330) is approximately 0.0002. b)P(X>340) is approximately 0.0294. c) P(335≤X≤345) is approximately 0.6415. d) P(X=300) is approximately 0.0004 of given probabilities

To find the probabilities using Excel's function options, we can use the binomial distribution function, which is provided as BINOM.DIST in Excel.

a) P(X=330):

=BINOM.DIST(330, 400, 0.8, FALSE)

The first argument is the specific value (330), the second argument is the total number of trials (400), the third argument is the probability of success (0.8), and the fourth argument FALSE indicates that we want the probability for a specific value.

The result is approximately 0.0002.

Therefore, P(X=330) is approximately 0.0002.

b) P(X>340):

=1 - BINOM.DIST(340, 400, 0.8, TRUE)

Since we want the probability of X being greater than 340, we can subtract the cumulative probability of X up to 340 from 1. We use the TRUE argument to indicate that we want the cumulative probability.

The result is approximately 0.0294.

Therefore, P(X>340) is approximately 0.0294.

c) P(335≤X≤345):

=BINOM.DIST(345, 400, 0.8, TRUE) - BINOM.DIST(334, 400, 0.8, TRUE)

To find the probability of X being between 335 and 345 (inclusive), we subtract the cumulative probability of X up to 334 from the cumulative probability of X up to 345.

The result is approximately 0.6415.

Therefore, P(335≤X≤345) is approximately 0.6415.

d) P(X=300):

=BINOM.DIST(300, 400, 0.8, FALSE)

The first argument is the specific value (300), the second argument is the total number of trials (400), the third argument is the probability of success (0.8), and the fourth argument FALSE indicates that we want the probability for a specific value.

The result is approximately 0.0004.

Therefore, P(X=300) is approximately 0.0004.

True. Exception reports show a greater level of detail than is included in routine reports.

Exception reports are reports that help in identifying data that does not conform to expected patterns. Exception reports show information about an exception in the data set.

This helps to identify irregularities or anomalies in data or system operations.Exception reports are used to analyze system performance, monitor resource consumption, and to detect unusual activity.

This type of report is important to identify issues or errors, where the routine reports or standard reports would not provide enough detail or insight to do so.

It provides detailed information on any unusual event or anomaly that occurred beyond the usual course of events or processes.Exception reports are generated and distributed when the data is not expected or when an event occurs that is outside of what is considered typical.

For example, a financial system might generate an exception report if a transaction is entered that exceeds the maximum allowed amount. This report would show the details of the transaction and highlight the exception.

The purpose of exception reports is to provide users with a higher level of detail than they would find in routine reports. Exception reports are used to highlight significant data, which will be used for further analysis or action.

Answer:

See attached. ∠A is a right angle, ∠B and ∠D are acute, ∠C is obtuse.

Step-by-step explanation:

     A right angle is defined as an angle equal to 90 degrees.

     An acute angle is defined as an angle less than 90 degrees.

     An obtuse angle is defined as an angle greater than 90 degrees.

     Using this information we will classify all of the four given angles.

∠A is a right angle, 90 = 90

∠B is acute angle, 60 < 90

∠C is obtuse angle, 160 > 90

∠D is acute angle, 70 < 90

The vertical distance through which the car rises is 16.7 m

"It is a triangle whose one of the angle is 90°."

In right triangle, for angle 'x',

sin(x) = (opposite side of angle x)/hypotenuse

For given example,

Consider the following figure for given situation.

A car travels 120 m along AC.

ΔABC is right triangle with hypotenuse AC.

∠C = 8°

Consider sine of angle C,

\(\Rightarrow sin(C)=\frac{AB}{AC}\\\\\Rightarrow sin(8^{\circ})=\frac{AB}{120}\\\\ \Rightarrow 0.1392=\frac{AB}{120}\\\\ \Rightarrow AB = 0.1392\times 120\\\\\Rightarrow AB = 16.70~ m\)

a = -1, b = 4, and c = 3.

Eva is correct - we can use Gaussian Elimination to solve this problem.

To solve this problem, we must first create an augmented matrix of the system of equations. We can do this by taking the equation f(x) = ar' + br + c and plugging in each of the given points, resulting in:

[1 2 a+b+c]
[-1 6 -a+b+c]
[2 3 2a+b+c]

Now, we can use Gaussian Elimination to solve this augmented matrix.

First, we'll eliminate the variable c from the first and second row by subtracting the first row from the second row, and the variable a from the first and third row by subtracting twice the first row from the third row.

We end up with this augmented matrix:

[1 2 a+b+c]
[0 8 -2a+2b+2c]
[0 -3 0]

Next, we'll eliminate the variable b by subtracting the second row from the third row.

This results in our final augmented matrix:

[1 2 a+b+c]
[0 8 -2a+2b+2c]
[0 0 -a]

We can now read off the coefficients: a = -1, b = 4, and c = 3.

The global extreme values of the function \(f(x,y) = 4x^3 + 4x^2y + 5y^2\) are a minimum of -1600/729 at (-10/9,20/27) and a maximum of 21875/256 at (5/2,-25/8).

To determine the global extreme values of the function \(f(x,y) = 4x^3 + 4x^2y + 5y^2\), we need to find the critical points of the function and then check the values of the function at these points and at the boundary of the region where we are interested in finding the extreme values.

To find the critical points, we need to find where the partial derivatives of the function are zero or undefined:

\(\partial f/ \partial x = 12x^2 + 8xy\)

\(\partial f/ \partial y = 8x^2 + 10y\)

Setting these partial derivatives equal to zero, we get:

\(12x^2 + 8xy = 0 -- > 4x(3x+2y) = 0\)

\(8x^2 + 10y = 0 -- > 4x^2 + 5y = 0\)

These equations are satisfied by either x = 0 or \(y = -4x^2/5, or 3x+2y = 0\) and \(4x^2+5y = 0.\) Solving for these values gives us the critical points: (0,0), (-10/9,20/27), and (5/2,-25/8).

Next, we need to check the values of the function at these critical points and at the boundary of the region where we are interested in finding the extreme values.

The region of interest is not given, so we assume it to be the entire xy-plane.

Now, we need to check the boundary of the region. The boundary can be divided into four parts: x = 0, x = 1, y = 0, and y = 1.

However, since the function has no restrictions on x and y, there is no boundary. Therefore, the global maximum and minimum occur at the critical points.

Therefore, the global extreme values of the function \(f(x,y) = 4x^3 + 4x^2y + 5y^2\) are a minimum of -1600/729 at (-10/9,20/27) and a maximum of 21875/256 at (5/2,-25/8).
