Answer: See explanation

Step-by-step explanation:

x=-(2-2*the square root of 6)/5, about 0.58

or

x=-(2+2*the square root of 6)/5, about -1.38

The values of the x from equation  \(5x^2+4x-4=0\) are  x = 0.5798 and -1.38.

Given that:

Equation:  \(5x^2+4x-4=0\)

To find the values of x that satisfy the equation \(5x^2+4x-4=0\), use the quadratic formula:

\(x = \dfrac{ -b \± \sqrt{b^2 - 4ac}}{ 2a}\)

Compare the equation with \(ax^2 + bx + c = 0\).

Here, a = 5, b = 4, and c = -4.

Plugging in the values to get,

\(x = \dfrac{-4 \± \sqrt{4^2 - 4 \times 5 \times (-4)}}{2 \times 5} \\x = \dfrac{-4 \± \sqrt{16 +80}}{10} \\x = \dfrac{-4 \± \sqrt{96}}{10}\\x = \dfrac{-4 \± {4\sqrt6}}{10}\)

So the solutions for x are calculates as:

Taking positive sign,

\(x = \dfrac{-4 + {4\sqrt6}}{10}\\x = \dfrac{-4 + {9.798}}{10}\\\)

x = 5.798/10

x = 0.5798

Taking negative sign,

\(x = \dfrac{-4 - {4\sqrt6}}{10}\\x = \dfrac{-4 - {9.798}}{10}\\\)

x = -13.798/10

x = -1.38

Hence, the exact solutions for the equation  \(5x^2 + 4x - 4 = 0\)  are x = 0.5798 and -1.38.

Hello.

In order to find the slope of the given line, we should use the slope formula:

\(\mathrm{\displaystyle\frac{y2-y1}{x2-x1}}\)

y₂= the y-coordinate of the second point (6

y₁= the y-coordinate of the first point (-14)

x₂=the x-coordinate of the second point (-10)

x₁=the x-coordinate of the first point (-4)

Let's plug in the values and solve:

\(\mathrm{\displaystyle\frac{6-(-14)}{-10-(-4)}=\frac{6+14}{-10+4} =\frac{20}{-6} =-\frac{20}{6} =-\frac{10}{3} }\)

An angle between 0 and 2π that is coterminal with a given angle can be found by adding or subtracting multiples of 2π until the angle falls within the specified range.

To find a coterminal angle, we can add or subtract 2π (which is equivalent to one full revolution) to the given angle. By doing this, we maintain the same initial position but change the number of complete revolutions made. If the resulting angle is still outside the range of 0 to 2π, we can continue adding or subtracting 2π until we obtain an angle within the desired interval.

For example, let's say we have an angle of 3π/4. To find a coterminal angle within the range of 0 to 2π, we subtract 2π from 3π/4:

3π/4 - 2π = -5π/4

The resulting angle is outside the desired range, so we add 2π instead:

-5π/4 + 2π = 3π/4

Now we have an angle of 3π/4, which is coterminal with the original angle and falls within the specified interval.

The expected value of the continuous random variable V is 5. The expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.

To calculate the expected value of a continuous random variable V with a given probability density function (PDF), we integrate the product of V and the PDF over its entire range.

The PDF of V is defined as:

f(v) = 6/24 = 0.25 for 3 ≤ v ≤ 7, and 0 otherwise.

The expected value of V, denoted as E(V), can be calculated as:

E(V) = ∫v * f(v) dv

To find the expected value, we integrate v * f(v) over the range where the PDF is non-zero, which is 3 to 7.

E(V) = ∫v * (0.25) dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * ∫v dv, with the limits of integration from 3 to 7.

E(V) = (0.25) * [(v^2) / 2] evaluated from 3 to 7.

E(V) = (0.25) * [(7^2 / 2) - (3^2 / 2)].

E(V) = (0.25) * [(49 / 2) - (9 / 2)].

E(V) = (0.25) * (40 / 2).

E(V) = (0.25) * 20.

E(V) = 5.

Therefore, the expected value of the continuous random variable V is 5.

The expected value represents the average value or mean of the random variable V. It is the weighted average of all possible values of V, with each value weighted by its corresponding probability. In this case, the expected value of V is 5, indicating that, on average, we expect the value of V to be around 5.

Answer:

The domain can either be discrete or continuous. A discrete function would have x-values that stand alone, but not have an interval around them. For example the number of children you have will be 0, 1, 2, 3, and so on, but nothing in between 1 and 2. A continuous function will have all values of x in an interval

help me by marking as brainliest....

A discrete function is a function in which the domain and range are each a discrete set of values, rather than an interval in . Recall from a prior lesson that an interval includes all values between the specified minimum and maximum.Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

The scale factor of the dilation of line segment ba for which the center of dilation is C, is 5.

Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.

Point c is the center of dilation. Line segment BA is dilated to create line segment b prime, a prime.  The image of the given problem is attached below. The length of CA is 4.

\(CA=4\)

The length of a prime is 16.

\(AA'=16\)

The new dimension will be,

\(CA'=CA+AA'\\CA'=4+16\\CA'=20\)

Now, the scale factor is the ratio of the new dimension to the original dimension. Thus, the scale factor of the dilation is,

The false positive and false negative rates for the medical test are given as:

A false positive is an outcome in which the model forecasts the positive class inaccurately. A real positive result is one in which the model accurately predicts the positive class.

To determine the false positives and false negatives of the tests, we use the principle of probability.

Probability (p) = Number of Favorable outcomes/Total number of Exhaustive outcomes

Recall that 240 of the 250 patients were accurately recognized. Also, 50 healthy people were diagnosed to have the ailment. Hence, the test's false positive (FP) and false negative (FN) rates can be estimated as follows:

Hence P (False Positive) = 50 / 750 = o.0667 or 6.67%

P (False Negative) = 10/750 = 0.0400 or 4.00%.

Therefore, the required rates are 6.67% and 4.00% accordingly.

The duration of the compression event is  100 degrees of crankshaft rotation by using the number of degrees of crankshaft rotation between the point where the intake valve closes (IVC) and the point where the exhaust valve opens (EVO).

To determine the duration of the compression event, we need to find the number of degrees of crankshaft rotation between the point where the intake valve closes (IVC) and the point where the exhaust valve opens (EVO).

Intake valve opens (IVO) at 8 degrees before top dead center (BTDC)

Intake valve closes (IVC) at 50 degrees after bottom dead center (ABDC)

Exhaust valve opens (EVO) at 50 degrees before bottom dead center (BBDC)

Exhaust valve closes (EVC) at 8 degrees after top dead center (ATDC)

First, we need to determine the position of the piston at each of these valve events. We know that the stroke of the engine is 180 degrees, so we can use this information to calculate the position of the piston at each event:

IVO: piston is at 8 degrees BTDC

IVC: piston is at 180 - 50 = 130 degrees ATDC

EVO: piston is at 180 + 50 = 230 degrees ATDC

EVC: piston is at 360 - 8 = 352 degrees BTDC

To find the duration of the compression event, we need to calculate the number of degrees of crankshaft rotation between IVC and EVO. We can do this by subtracting the position of the piston at IVC from the position of the piston at EVO:

Duration of compression event = EVO - IVC

= 230 - 130

= 100 degrees

Therefore, the duration of the compression event is 100 degrees of crankshaft rotation.

The general solution to the differential equation y'' + 16y = 0 is y(x) = (c₁ + c₂) * cos(4x)

To solve the differential equation y'' + 16y = 0 using reduction of order, we'll assume a second solution of the form y₂(x) = u(x) * y₁(x), where y₁(x) is a known solution and u(x) is an unknown function.

Given y₁(x) = cos(4x), we'll differentiate it to find y₁'(x) and y₁''(x):

y₁'(x) = -4sin(4x)

y₁''(x) = -16cos(4x)

Now we substitute y₂(x) = u(x) * y₁(x) into the original differential equation:

y'' + 16y = 0

(-16cos(4x)) + 16(u(x) * cos(4x)) = 0

Simplifying the equation:

-16cos(4x) + 16u(x) * cos(4x) = 0

cos(4x)(-16 + 16u(x)) = 0

For this equation to hold for all values of x, we must have (-16 + 16u(x)) = 0.

Solving for u(x):

-16 + 16u(x) = 0

16u(x) = 16

u(x) = 1

Now we have the second solution:

y₂(x) = u(x) * y₁(x)

y₂(x) = 1 * cos(4x)

y₂(x) = cos(4x)

Therefore, the general solution to the differential equation y'' + 16y = 0 is:

y(x) = c₁ * y₁(x) + c₂ * y₂(x)

y(x) = c₁ * cos(4x) + c₂ * cos(4x)

y(x) = (c₁ + c₂) * cos(4x)

Where c₁ and c₂ are arbitrary constants.
