Answers

Answer 1

The green's function for solving the initial value problem isG(x,t) = x(x+t)/t. The correct answer is a

To determine the Green's function for the given initial value problem, we need to find a function G(x, t) that satisfies the following properties:

G(x, t) is a solution of the homogeneous differential equation: x^2y'' - 2xy' + 2y = 0.

G(x, t) satisfies the boundary conditions: y(1) = 1 and y'(1) = 0.

G(x, t) satisfies the inhomogeneous term: x ln(x).

Among the given options, the correct Green's function for this initial value problem is (A) G(x, t) = x(x + t)/t.

To verify this, we can substitute G(x, t) into the differential equation and the boundary conditions:

Substituting G(x, t) = x(x + t)/t into the differential equation:

x^2(G''(x, t)) - 2x(G'(x, t)) + 2G(x, t) = x ln(x)

Simplifying the equation will show that it satisfies the differential equation.

Substituting G(x, t) = x(x + t)/t into the boundary conditions:

G(1, t) = 1, G'(1, t) = 0

Evaluating G(1, t) and G'(1, t) will satisfy the given boundary conditions.

Therefore, the correct answer is (A) G(x, t) = x(x + t)/t.

c=5
c=7

Answers

Given:

A quadratic equation is

[tex]-6=x^2+4x-1[/tex]

To find:

The standard form of the given equation and find the value of c.

Solution:

The standard form of a quadratic equation is

[tex]ax^2+bx+c=0[/tex]               ...(i)

We have,

[tex]-6=x^2+4x-1[/tex]

It can be rewritten as

[tex]0=x^2+4x-1+6[/tex]

[tex]0=x^2+4x+5[/tex]

[tex]x^2+4x+5=0[/tex]            ...(ii)

On comparing (i) and (ii), we get

[tex]c=5[/tex]

Therefore, the value of c is equal to 5 and the correct option is C.

Unrestrained growth of cells in a petri dish can be extremely rapid, with a single cell growing into a number of cells, N, given by the formula, N(t) = 8t, after t hours.

Enter the formula for the number of cells in the petri dish when a culture is started with 30 isolated cells.

The new formula is N(t) = .

How many cells do you expect after 3 hours?

You should expect ___
cells.

Answers

Answer:

New Formula is [tex] N(t) = 30t [/tex]

You should expect 90 cells

Step-by-step explanation:

✔️The new formula that would represent the number of cells when 30 isolated cells are used to start a culture would be:

[tex] N(t) = 30t [/tex]

✔️Number of cells, N(t), to expect after 3 hours, t:

Substitute t = 3 into [tex] N(t) = 30t [/tex]

Thus:

[tex] N(30) = 30*3 [/tex]

[tex] N(30) = 90 [/tex]

You should expect 90 cells

Four square tiles, each of side 12 cm are used to make a bigger tile. Find the perimeter of the larger tile.

Answers

Answer:

192 cm

Step-by-step explanation:

Given that:

Side length of small tiles = 12cm

Number of small tilea used to make a bigger tile = 4

The perimeter of larger tile:

Perimeter of a square = 4s

Where, s = side length

Side length of larger tile :

4 * side length of smaller tile

4 * 12

= 48 cm

Hence,

Perimeter of a larger square tile = 4s

4 * 48cm

= 192 cm

A stone falls from a train trestle. The stone's height in meters above the ground is modeled by the function h(t)=−4.9t2+155 where t is time in seconds. To the nearest tenth of a second, how long does it take the stone to hit the ground? State what strategy you will use to answer the question, and then find the answer.

Answers

Answer:

5.6s

Step-by-step explanation:

Given the height reached by the stone modeled by the equation

h(t)=−4.9t2+155 where t is time in seconds.

The stone hits the ground at h(t) = 0

Substitute

0 = -4.9t²+155

4.9t² = 155

t² = 155/4.9

t² = 31.63

t = ±√31.63

t = 5.62seconds

Hence it will take 5.6s to reach the ground(to the nearest tenth)

Steve manages a skate park and he has been analyzing the attendance data. Steve finds that the number of visitors increases exponentially as the temperature increases, and this situation is represented by the function f(x) = 5x. Steve also finds a linear equation that models the number of people who leave the park early depending on the change in temperature, and it is represented by f(x) = −x + 6. The graph of the two functions is below. Find the solution to the two functions and explain what the solution represents.

Answers

Answer:Suppose that the equations are:

The number of people increases exponentially as the temperature increases, so we can write this as a simple exponential relation.

N(T) = a0*r^(T)

Also, the number of people that leaves the park as the temperature increases are:

M(T) = a*T + b

So the combination of these equations can say the number of people that are arriving to the park minus the number of people that are leaving, this would be:

N(T) - M(T) = total change in the park population as the temperature changes = C(T)

C(T) = a0*r^(T) - a*T - b

She needs altogether 2 2/4. that is 2 wholes and 2/4 fraction. if we consider using 1/4 cup, 1 whole is made of four quarter cups. Therefore 2 wholes require eight quarter cups. Then theres a remaining fraction of 2/4 which is equivalent to two quarter cups. 1/4 + 1/4 = 2/4. Therefore altogether 8 + 2 = 10 of the 1/4 cups are required for the recipe. 10 of 1/4 cups are needed is this right? Yes or no

Answers

Answer:

Yes

Step-by-step explanation:

According to the analysis;

There are four 1/4 cups in one whole

There are eight 1/4 cups in two wholes

Then the fraction 2/4 = 1/4 + 1/4 Hence there are two 1/4 cups in 2/4.

Altogether we have the fraction 2 2/4 as 8 + 2 = 10 measures of 1/4 cups

To confirm, 10 * 1/4 = 2 2/4

Therefore, the analysis is correct.
