The general solution to the non-homogeneous equation is,

y(t) = c₁\(t^{1/2}\) + c2/t + t - 1/(2t³)

where c₁ and c₂ are constants determined by the initial or boundary conditions of the problem.

Now, For this differential equation, we will use the method of undetermined coefficients.

We first need to find the general solution to the homogeneous equation:

2t²*y''(t) + (3/2t)*y'(t) - (1/2t²)*y(t) = 0

We assume a solution of the form y_h(t) = \(t^{r}\). Substituting this into the equation, we get:

2t²r(r-1)*\(t^{r - 2}\) + (3/2t)*r * \(t^{r - 1}\) - (1/2t²)* \(t^{r}\) = 0

Simplifying, we get:

2r*(r-1) + (3/2)*r - (1/2) = 0

Solving for r, we get:

r = 1/2, -1

Therefore, the general solution to the homogeneous equation is:

y_h(t) = c₁\(t^{1/2}\) + c₂/t

To find a particular solution to the non-homogeneous equation, we assume a solution of the form y_p(t) = At + B.

Substituting this into the equation, we get:

2t²y''(t) + (3/2t)y'(t) - (1/2t²)*y(t) = t

Differentiating twice, we get:

2t²*y'''(t) + 6ty''(t) - 3y'(t) + (1/t²)*y(t) = 0

Substituting y_p(t) into this equation, we get:

2t²0 + 6tA - 3A + (1/t²)(At + B) = 0

Simplifying, we get:

(A/t)*[(2t³ - 1)B + t⁴] = t

Since this equation must hold for all values of t, we equate the coefficients of t and 1/t:

(2t³ - 1)B + t⁴ = 0

A/t = 1

Solving for A and B, we get:

A = 1

B = -1/(2t³)

Therefore, a particular solution to the non-homogeneous equation is:

y_p(t) = t - 1/(2t³)

So, The general solution to the non-homogeneous equation is the sum of the homogeneous and particular solutions:

y(t) = c₁\(t^{1/2}\) + c2/t + t - 1/(2t³)

where c₁ and c₂ are constants determined by the initial or boundary conditions of the problem.

Answer:

x>-2

Step-by-step explanation:

So, lets start by distrubuting the -3 to x:

-3x-4<2

Then lets just start solving. First lets add 4 to both sides to get -3x alone:

-3x<6

Now lets divide -3 from both sides to get x alone:

x<-2

There is one thing we must remember, however.

When dividing a inequality by a negative, the sign is flipped.

So in this case, the < is now >:

x>-2

This basically means a solution is any value greater than -2!

To find the equation of a line that goes through two points, you can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where "m" is the slope of the line and "b" is the y-intercept (the point where the line crosses the y-axis).

To find the slope of the line, you can use the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are two points on the line.

In this case, we are given the points (4, 5) and (8, 7), so we can plug these values into the formula for the slope:

m = (7 - 5) / (8 - 4)

= 2 / 4

= 1/2

Now that we know the slope of the line, we can use the point-slope form of the equation of a line to find the equation of the line:

y - y1 = m(x - x1)

where (x1, y1) is any point on the line and "m" is the slope of the line.

In this case, we are given the point (4, 5), so we can plug these values into the formula:

y - 5 = (1/2)(x - 4)

y = (1/2)x + 3

So, the equation of the line that goes through (4,5) and (8,7) is y = (1/2)x + 3.

Therefore, the correct answer is (b) y = /2x+3.

Explanation:

We have two smaller right triangles that are glued together so to speak.

The base of the smaller triangle on the left is 5 while the height is h.

Let's use the tangent rule to find the value of h

tan(angle) = opposite/adjacent

tan(55) = h/5

5*tan(55) = h

h = 5*tan(55)

h = 7.14074003371058

Make sure your calculator is in degree mode. That value of h above is approximate.

--------------------------

Now focus on the smaller triangle on the right

It has the same height value h. This side is the adjacent side while x is the hypotenuse.

We'll use the cosine ratio

cos(angle) = adjacent/hypotenuse

cos(42) = h/x

cos(42) = 7.14074003371058/x

x*cos(42) = 7.14074003371058

x = 7.14074003371058/cos(42)

x = 9.6088135029715

x = 9.6

Answer:

Half;  twice

Step-by-step explanation:

In a circle, the radius is said to be the distance from the center of the circle to any point on the edge of the circle, it is denoted as "r". The radius is called a radii if it is more than one.. The radius of a circle is half the length of the diameter of a circle because the diameter of a circle is the distance of the line that passes through the center of a circle touching both edges of the circle. It is denoted as "d".

Thus,

2r = d

r = d/2

For example, if the radius of a circle is 10cm, the diameter of the circle will be calculated as: d = 2 * 10 = 20cm. Which means if the radius is 10cm, diameter will be 20cm.

Therefore, the radius of a circle is half the length of its diameter. the diameter of a circle is twice the length of its radius

(a) Yes, we have enough information to compute Probability P(A or B).

(b) If we know P(A) and P(B), we have enough information to compute P(A or B).

(a) The probability of the union of two events (A or B) is given by the formula P(A or B) = P(A) + P(B) - P(A and B)

We know P(A) and P(B), but we don't know P(A and B) - the probability that both events occur simultaneously. Therefore, we cannot compute P(A or B) with certainty unless we are given additional information about the relationship between A and B.

(b) If we know that events A and B are mutually exclusive, then we have enough information to compute P(A or B). Mutually exclusive events are events that cannot occur simultaneously, which means that P(A and B) = 0.

In this case, the formula for the probability of the union simplifies to:

P(A or B) = P(A) + P(B)

Since we know P(A) and P(B), we can simply add them to obtain P(A or B). Therefore, in this case, we have enough information to compute P(A or B).

B is the common part of p and q

The conditional statement P→Q is logically equivalent to its contrapositive ¬Q→ ¬P .

Conditional statements are ones that begin with a hypothesis and end with a conclusion or rationale. It is sometimes referred to as the "If-then" statement.

In mathematics, a statement is a declarative utterance that can only be true or false. A statement is sometimes known as a proposition. It is critical that there be no ambiguity.

A contrapositive assertion is created when we reverse the hypothesis and conclusion of a statement and disprove both of them.

To put it another way, we must first find the inverse of the supplied conditional statement before swapping the places of the hypothesis and conclusion to find the contrapositive.

We have, p→q , then the inverse of both the statements is given by ¬p and ¬q .

So, the contrapositive statement will be ¬p → ¬q

The equation of the line having slope = -1 and passing through a point (-3, 5) is y = -x + 2 and graph is given below.

The general equation of a line is y = m × x + c, where m is the slope and c is the y-intercept of the line.

Given slope is equal to -1.

Therefore the equation of the required line is y = (-1) × x + c.

Given that this line passes through the point (-3, 5).

Therefore we have 5 = (-1) × (-3) + c

⇒ 5 = 3 + c

⇒ 5 - 3 = c

⇒ 2 = c

⇒ c = 2

Therefore the y-intercept of the required line in cartesian coordinate form is (0, 2).

Therefore the required equation of the line is y = (-1) × x + 2

⇒ y = -x + 2.

So the final expression is: (change in y/y) = n (change in a/a).

We can start by taking the natural logarithm of both sides of the equation:

ln(y) = ln(aⁿ)

Using the rule that ln(aⁿ) = n ln(a), we can simplify this to:

ln(y) = n ln(a)

Next, we can take the derivative of both sides with respect to a:

d/d(a) ln(y) = d/d(a) (n ln(a))

Using the chain rule, we can simplify the right-hand side to:

d/d(a) ln(y) = n (1/a)

Now, we can multiply both sides by a/y:

a/y * d/d(a) y = n(a/y) * (1/a)

A parametrization for the line segment with endpoints (-4,5) and (-9,-10) is given by x = -4 - 5t and y = 5 - 15t, where 0 ≤ t ≤ 1.

To find a parametrization for the given line segment with endpoints (-4,5) and (-9,-10), we can use the parametric form of the equation of a straight line, which is given by x = x1 + t(x2 - x1) and y = y1 + t(y2 - y1), where (x1,y1) and (x2,y2) are the endpoints of the line segment and t is a parameter that varies from 0 to 1.

Taking (x1,y1) = (-4,5) and (x2,y2) = (-9,-10), we get the following parametric equations for the line segment:

x = -4 + t(-9 - (-4)) = -4 - 5t

y = 5 + t(-10 - 5) = 5 - 15t

The parameter t varies from 0 to 1, so as t ranges from 0 to 1, the point (x,y) traces out the line segment joining the points (-4,5) and (-9,-10).

Therefore, a parametrization for the line segment with endpoints (-4,5) and (-9,-10) is given by x = -4 - 5t and y = 5 - 15t, where 0 ≤ t ≤ 1.
