Answer:

slope (m) is 4, y-intercept (m) is -3

Step-by-step explanation:

y=4x-3

use y¹-y² over x¹-x² to find slope, then use one of the points to fill in for x and y to find y-intercept

Answer:

The Y intercept is 9, and The Slope is 7x

Answer:

slope: 7 (or 7/1)

y int: 9

Step-by-step explanation:

Slope intercept formula is y=mx+b

(m) is slope

(b) is y intercept

so in

y=9+7x

we can flip the numbers around

y=7x+9

so 7 is our slope and 9 is the y intercept

Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape.

Given that, Triangle ABC is dilated into A'B'C'

We know that dilated triangles are similar

Hence, their corresponding sides are in equal ratio,

BC : B'C' = AC : A'C'

6 : 4 = 3 : x

Step-by-step explanation:

Total time taken by Denise and Rachel to paint the room together us around 32.10 hours.

To determine how many hours it would take Denise and Rachel to paint the living room together:

Denise can complete the job within 55 hours, so her work rate is 1/55 of the job per hour.

Rachel can complete her job in 77 hours, so her work rate is 1/77 of the job per hour.

When they work together to paint, their work rates are also combined. Therefore, the combined work rate of Denise and Rachel is the sum of their individual work rates:

= 1/55 + 1/77

= 0.01818 + 0.01299

= 0.03117

To find the time taken by them for working together, we take the reciprocal of the combined work rate obtained:

1 / 0.03117 = 32.10 hours

Therefore, it would take Denise and Rachel approximately around 32.10 hours to paint the living room together.

The y-intercept of 14 may serve as a reference point for the amount of damage to the head gaskets when the temperature is relatively low.

What is an equation?

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equals sign (=).

In the equation y = -23x + 14, y represents the amount of damage to the head gaskets on the trucks in Sven's fleet, and x represents the ambient temperature.

The constant term, 14, is the y-intercept of the equation. It represents the value of y when x is equal to zero.

In this context, the y-intercept of 14 means that when the ambient temperature is zero (which is unlikely in most cases), the amount of damage to the head gaskets on the trucks in Sven's fleet is equal to 14. However, this value may not be meaningful in practical terms since it is unlikely that the ambient temperature will ever be exactly zero.

Therefore, in practical terms, the y-intercept of 14 may serve as a reference point for the amount of damage to the head gaskets when the temperature is relatively low.

It is important to note that the value of y will decrease by 23 for every increase of one unit in the ambient temperature (x).

Answer:

2.25 feet, 45 inches, and 6 yards

Step-by-step explanation:

first, convert all to the same unit of measurement

I will use inches

45 inches = 45 inches

6 yards, 1 yard = 3 feet so 6 yards are equal to 18 feet and 1 foot is equal to 12 inches so 12*18 is 216 inches so 6 yards = 216 inches

Next 1 foot equals 12 inches so 2.25 * 12 = 27 so 2.25 feet = 27 inches.

Now let's look at the complete conversion

45 inches

6 yards = 216 inches

2.25 feet = 27 inches

looking at the inches we can see that 27 is the least then 45 then 216 therefore

2.25 feet < 45 inches <  6 yards so the order is

2.25 feet, 45 inches, and 6 yards

Domain : Set of all possible input values (x-values) on a graph

Codomain : Set of all possible out values for the input values (y-values) on the graph

Range : Actual output values for the input values (x-values) given on the graph.

Therefore, for the given graph,

Domain : (-∞, ∞)

Codomain : (-∞, 2]  

Range : (-∞, 2]

From the given graph every input value there is a image or output value.

Therefore, the given function is onto.

Answer:

If the plot point was dilated by a scale factor, it would be multiplying the scale factor with each X and Y. Therefore it would be (-5,-5)

The image of (-1, -1) after the dilation by a scale factor of 5 centered at the origin is (-5, -5).

To find the image of (-1, -1) after a dilation by a scale factor of 5 centered at the origin, we can apply the formula for dilation in the coordinate plane.

The formula for dilation with a scale factor of k centered at the origin is (k * x, k * y), where (x, y) is the original point.

In this case, the original point is (-1, -1), and the scale factor is 5. Applying the dilation formula, we have:

Image = (5 * (-1), 5 * (-1))

= (-5, -5)

This means that the point (-1, -1) is dilated by a factor of 5, and its position is shifted five times farther from the origin in both the x and y directions.

Answer:

the midline is the line:

y = 0.

Step-by-step explanation:

The midline of a function is a horizontal line that divides evenly the graph of the function in two parts.

Particularly, for trigonometric functions, we usually have:

f(x) = A*sin(k*x + p) + M

Where:

A is the amplitude.

x is the variable

k is a constant related to the frequency of the function.

p is a phase shift

M is the midline of the function, which means that the line that divides evenly the graph is y = M.

For our case, we have:

y = f(x) = 3*sin(2*x - π)

Then:

A = 3

k = 2

p = -π

And we do not have a constant term in that equation, this means that:

M = 0

This means that the line that divides evenly the graph is the line y = 0.

The estimated change in yy using differentials is -0.00679. This means that if xx is increased by 0.005, then yy is estimated to decrease by 0.00679. The differential of yy is dy=-5sin(5x)dxdy=−5sin⁡(5x)dx. We are given that y=cos(5x)=π/30y=cos⁡(5x)=π/30 and x=0.055x=0.055.

We want to estimate ΔyΔy, which is the change in yy when xx is increased by 0.005. We can use the differential to estimate ΔyΔy as follows:

Δy≈dy≈dy=-5sin(5x)dx

Plugging in the values of y, x, and dxdx, we get:

Δy≈-5sin(5(0.055))(0.005)≈-0.00679

Therefore, the estimated change in yy using differentials is -0.00679.

The general solution to the given differential equation is y = -2r + Cy + D, where C and D are constants.

The given differential equation is d²y/dy² + 2d²r/da dr = 0. In order to solve this equation, we will need to find the general solution that satisfies the equation.

To solve the given differential equation d²y/dy² + 2d²r/da dr = 0, we can start by rearranging the terms. Let's separate the variables and rewrite the equation as d²y/dy² = -2d²r/da dr.

Next, we integrate both sides of the equation with respect to the corresponding variables. Integrating d²y/dy² with respect to y gives us y', and integrating -2d²r/da dr with respect to r gives us -2r'.

Now we have the equation y' = -2r' + C, where C is the constant of integration.

To further simplify the equation, we can rearrange it as dy/dy = -2dr/da + C.

Integrating both sides with respect to y, we obtain y = -2r + Cy + D, where D is another constant of integration.

Therefore, the general solution to the given differential equation is y = -2r + Cy + D, where C and D are constants.

a) The recurrence relation an = -3an-1 with a₁ = -1 can be solved as an = (-3)ⁿ⁻¹.

b) The recurrence relation an = an-1 + an-2 with a₀ = 0 and a₁ = 1 can be solved using the Fibonacci sequence formula, an = Fₙ₊₁, where Fₙ is the nth Fibonacci number.

c) The recurrence relation an = -6an-1 - 9an-2 with a₀ = -1 and a₁ = -3 can be solved as an = 3ⁿ - 2ⁿ.

a) For the recurrence relation an = -3an-1 with a₁ = -1, we notice that the ratio between consecutive terms is a constant (-3). This means that each term can be expressed as a power of -3 raised to a certain exponent. In this case, we have an = (-3)ⁿ⁻¹.

b) The recurrence relation an = an-1 + an-2 with a₀ = 0 and a₁ = 1 is a well-known relation that corresponds to the Fibonacci sequence. The Fibonacci sequence is defined by the recurrence relation Fn = Fn-1 + Fn-2 with F₀ = 0 and F₁ = 1. By comparing the given relation with the Fibonacci relation, we can conclude that an = Fₙ₊₁, where Fₙ is the nth Fibonacci number.

c) For the recurrence relation an = -6an-1 - 9an-2 with a₀ = -1 and a₁ = -3, we can rewrite it as a quadratic equation in terms of aₙ. By solving the quadratic equation, we find that the characteristic equation is x² + 6x + 9 = 0, which factors as (x + 3)² = 0. This means that the roots of the characteristic equation are both -3. Consequently, the solution to the recurrence relation is an = A(-3)ⁿ + Bn(-3)ⁿ, where A and B are constants determined by the initial conditions a₀ and a₁. By substituting the given initial conditions, we can solve for the values of A and B, leading to the final solution an = 3ⁿ - 2ⁿ.

The system defined by the impulse response h(n) = 28(n+3) + 28n + 28(n-3) can be represented as h(n) = 28δ(n+3) + 28δ(n) + 28δ(n-3), where δ(n) denotes the unit impulse function.

In terms of causality, we can determine whether the system is causal by examining the impulse response. If the impulse response h(n) is non-zero only for n ≥ 0, then the system is causal. In this case, since the impulse response h(n) is non-zero for n = -3, 0, and 3, the system is not causal.

To determine the stability of the system, we need to examine the summation of the absolute values of the impulse response. If the summation is finite, the system is stable. In this case, we can calculate the summation as ∑|h(n)| = 28 + 28 + 28 = 84, which is finite. Therefore, the system is stable.

However, since the impulse response is given in the time domain and not in a closed-form expression, it is not possible to directly determine the frequency response without further manipulation or additional information.

Given the absence of specific frequency domain information or a closed-form expression for the frequency response, it is not possible to accurately represent the module and phase of the system H(e^ω) without further calculations or additional details about the system.

The resultant velocity and acceleration of the skier at t=4.00 sec on the ski jump path are 12.8 m/s and 45.9 m/s², respectively.

To find the resultant velocity, first find the velocity vector components using the parametric equations:

vx = 7.00t, vy = 0.48t³ - 6.00t²/√(t⁴+1)

At t=4.00 s, vx = 28.0 m/s and vy = 10.50 m/s. The resultant velocity is the magnitude of the velocity vector, given by:

|v| = √(vx² + vy²) = 12.8 m/s

To find the acceleration vector components, differentiate the velocity vector components with respect to time:

ax = 7.00 m/s², ay = 1.44t² - 12.00t/√(t⁴+1) - 6.00t³(t⁴+1)^(-3/2)

At t=4.00 s, ax = 7.00 m/s² and ay = 45.9 m/s². The acceleration vector magnitude is:
