Answer:

y = 3 x − 3

Step-by-step explanation:

The equation for slope-intercept form is as follows:

To find  c , substitute  x = 3 ,  y= 6  and  m = 3  into the equation,6=3 (3 ) + c c= 6 − 9 c = − 3  Since we found  m = 3  and  c= − 3 , we can form the equation,  = 3 x− 3

To reduce the third-order ordinary differential equation y - y" - 4y + 4y = 0 into a companion system of linear equations, we introduce new variables u and v:

Let u = y,

v = y',

w = y".

Taking the derivatives of u, v, and w with respect to the independent variable (let's denote it as x), we have:

du/dx = y' = v,

dv/dx = y" = w,

dw/dx = y"'.

Now we can rewrite the given differential equation in terms of u, v, and w:

u - w - 4u + 4u = 0.

Simplifying the equation, we get:

-3u - w = 0.

This equation can be expressed as a system of first-order linear differential equations as follows:

du/dx = v,

dv/dx = w,

dw/dx = -3u - w.

Now we have a companion system of linear equations:

du/dx = v,

dv/dx = w,

dw/dx = -3u - w.

To solve this system completely, we need to find the solutions for u, v, and w. By solving the system of differential equations, we can obtain the solutions for u(x), v(x), and w(x), which will correspond to the solutions for y(x), y'(x), and y"(x), respectively.

The exact solutions for this system of differential equations depend on the initial conditions or boundary conditions that are given. By applying appropriate initial conditions, we can determine the specific solution to the system.

Answer: 3

Step-by-step explanation:

The equation given is written in slope-intercept form, which is y=mx+b. x and y are the coordinate points. m is the slope, and b is the y-intercept. In the given equation +3 is in place of the m. Therefore, the slope is 3, NOT 3X.

Answer:

Use the quotient property of logarithms, logb(x)−logb(y)=logb(xy) log b ( x ) - log b ( y ) = log b ( x y ) . log3(4010) log 3 ( 40 10 ). Step 2.

Answer:

\(Rate = 0.125\)

Step-by-step explanation:

Given

\(Daily\ Cups = 500\)

\(Weekly\ Cups =4000\)

Required

Determine the day to week rate

This can be calculated by dividing the daily medicine cups by the weekly cups;

\(Rate = \frac{Daily}{Weekly}\)

Substitute 500 for Daily and 4000 for Weekly

\(Rate = \frac{500}{4000}\)

\(Rate = 0.125\)

Hence, the rate of the daily to weekly medicine cup is 0.125

Angles outside a circle are half the difference of the measures of the intercepted arcs.

78 - 12 = 66

66/2 = 33

The angle is 33 degrees

Answer:

The answer is 33 degrees.

Step-by-step explanation: Because the angle is in a circle, we have to divide the answer we get by 2 to get 33. 78-12=66 and divided by 2 is 33.

The constant torque required to bring the flywheel up to an angular speed of 400 rev/min in 8.00 s, starting from rest, is 5755.17 N m.

The constant torque required to bring the flywheel up to an angular speed of 400 rev/min can be calculated using the rotational kinematic equation:

ω = ω0 + αt

where ω0 = 0 (initial angular velocity), ω = (400 rev/min)(2π rad/rev) = 4188.79 rad/s (final angular velocity), α is the angular acceleration, and t = 8.00 s is the time interval.

The angular acceleration can be determined using the rotational analog of Newton's second law, τ = Iα, where τ is the torque applied to the flywheel and I is its moment of inertia:

α = τ/I

Substituting this expression for α into the first equation, we get:

ω = (τ/I)t

Solving for τ, we get:

τ = Iω/t

Substituting the given values, we get:

τ = (1.10 kg m²)(4188.79 rad/s)/8.00 s = 5755.17 N m

Therefore, the constant torque required to bring the flywheel up to an angular speed of 400 rev/min in 8.00 s, starting from rest, is 5755.17 N m.

The scenario involves dependent events, as the first event affects the second event, making them dependent rather than independent.

The scenario described involves dependent events. This is because the outcome of the first event, which is choosing a student to lead the first group, affects the outcome of the second event, which is choosing a student to lead the second group.

Specifically, since the teacher cannot pick the same student to lead both groups, there are fewer students available to choose from for the second group leader after the first group leader has been chosen. This events between the events is what makes them dependent rather than independent.

To describe the association of a scatterplot, we need to analyze the pattern of the plotted points.

If the scatterplot shows a clear trend where the points are sloping upwards from left to right, it indicates a positive association. On the other hand, if the points are sloping downwards from left to right, it suggests a negative association.

If the points roughly form a straight line, it indicates a linear association. However, if the points do not follow a straight line and instead have a curved or nonlinear pattern, it suggests a nonlinear association.

The strength of the association can be determined by how closely the points cluster around the trend line. If the points are tightly clustered around the trend line, it indicates a strong association. Conversely, if the points are spread out and do not closely follow the trend line, it suggests a weak association.

A perfect association implies that all points lie exactly on a straight line, indicating a strong and precise relationship between the variables.

Combining negatively correlated assets with the same expected return results in a portfolio with the same level of expected return but a lower level of risk.

When assets have a negative correlation, their returns tend to move in opposite directions. By combining these assets in a portfolio, their negative correlation offsets each other's risks to some extent. As a result, the overall risk of the portfolio is reduced.

However, the expected return of the portfolio remains the same as the individual assets, assuming they have the same expected return. This is because the negative correlation does not affect the average return of the assets, only their volatility. The diversification benefits provided by negatively correlated assets help to reduce the overall risk of the portfolio, making it less volatile than the individual assets.

Therefore, combining negatively correlated assets with the same expected return results in a portfolio with the same level of expected return but a lower level of risk. This is a desirable outcome for investors as it allows them to achieve a certain level of return while minimizing the overall risk in their investment portfolio.

Part A; Rebecca's current balance is $2500. Part B; Rebecca can save $27 by making the purchase on the last day of the billing cycle.

Part A:

Rebecca's finance charge is calculated using the following formula:

Finance charge = APR / 12 × (Average daily balance) × Number of days in billing cycle

Rebecca's APR is 24%, her average daily balance is x + $1400 / 28, and her billing cycle is 28 days. Her finance charge is $51.

Substituting these values into the formula:

$51 = (24 / 12) × ((x + $1400) / 28) × 28

Solving for x:

x = $2500

Therefore, Rebecca's current balance is $2500.

Part B:

If Rebecca makes the purchase on the first day of the billing cycle, her average daily balance will be $2500 + $1400 / 28 = $267.86.

Her finance charge will then be:

(24 / 12) × ($267.86) × 28 = $78

Therefore, Rebecca can save $78 - $51 = $27 by making the purchase on the last day of the billing cycle instead of the first day.

The solution to this question is as the function could be horizontally translated to the left as follows: Therefore,g(x) = 3x +6

The term "function" refers to the relationship between a collection of inputs and outputs with one each. Simply described, a function is an association of inputs where each input is coupled with exactly one output. Every function has an associated domain, codomain, or range. The most common way to represent a function is as f(x), where x represents the input..

Here,

f(x)=3x+4

The value of the standard deviation of the variance S is equivalent to 250 and the value of the variance (S) is equivalent to 62500.

Given that:

2Ax = 0.08

Ax = 0.2

A fully discrete whole life insurance issued to (x) is 1000.

Firstly we have to find out the value of variance S.

Variance S = (insurance issued)^2 * [2Ax - Ax^2]/(1- Ax)^2

Variance S = (1000)^2 * [0.08 -  0.2^2]/(1- 0.2)^2

Variance S = (1000)^2 * [0.04]/.64

Variance S = (1000)^2 * .0625

Variance S = 62500

Standard deviation of S = (insurance issued) * [\(\sqrt{2Ax - Ax^2}\)]/(1- Ax)

Standard deviation = 1000 * [\(\sqrt{0.08 - 0.2^2}\)]/(1- 0.2)

Standard deviation = 1000 * 0.2/0.8

Standard deviation = 1000 * 1/4 = 250
