Answer: The answer is B) y < 0

Answer: B

Step-by-step explanation:

The principal that will grow to $5,100 in two years, eight months at 4.3% compounded semi-annually is approximately $4,568.20.

To find the principal that will grow to $5,100 in two years and eight months at 4.3% compounded semi-annually, you can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:
A = final amount ($5,100)
P = principal amount (what we're trying to find)
r = annual interest rate (4.3% or 0.043)
n = number of times interest is compounded per year (semi-annually, so 2)
t = time in years (2 years and 8 months or 2.67 years)

First, plug in the values:

$5,100 = P(1 + 0.043/2)^(2*2.67)

Next, solve for P:

P = $5,100 / (1 + 0.043/2)^(2*2.67)

P = $5,100 / (1.0215)^(5.34)

P = $5,100 / 1.11726707

P ≈ $4,568.20

The principal that will grow to $5,100 in two years, eight months at 4.3% compounded semi-annually is approximately $4,568.20.

175/250 or %70

Hope this answers your question!

Answer:

175 people would be expected to be carrying a purse.

Step-by-step explanation:

7/10 people who entered were carrying a purse and if you say 250 people entered the store in one day the number of people would now be 250 instead of 10.

Since I made it into a fraction form you would need to find a numerator that would make the ratio equal. 7/10 = ?/250 Since 10 is a factor of 250 you would divide 250 by 10 and you would get 25. Since 10 * 25 is 250 you would also multiply the numerator, which is 7, by 25. 7 * 25 is 175. The ratio 7/10 = 175/250 is now equal.

The answer would be 175 would be expected to be carrying a purse since I had made the numerator of the fraction the number of people who were expected to bring a purse and the denominator the number of people entering the store.

Step-by-step explanation:

The method of reduction of order is a technique used to find a second solution to a homogeneous linear differential equation when one solution is already known.

However, it cannot be directly used for nonhomogeneous linear differential equations. In nonhomogeneous equations, the method of undetermined coefficients or variation of parameters is typically used to find a particular solution.

Therefore, the statement "the method of reduction of order can also be used for the nonhomogeneous equation" is false. It is important to understand the different techniques for solving differential equations, and to choose the appropriate method based on the type of equation and boundary conditions given.

The simple interest was $10.5 and the amount after 1 year would be $360.5 in her account.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

We have been given data as

Principal amount (P) = $350

Time (T) = 1 year

The rate of interest (R) = 3%

Simple interest= P × R × T

Simple interest = 350 × 3/100 × 1

Simple interest = $10.5

So the amount after 1 year would be P + S.I. = 350 + 10.5 = $360.5

Therefore, the simple interest would be $10.5 and the amount after 1 year would be $360.5.

To solve the given system of differential equations using the Laplace transform method, we apply the Laplace transform to each equation and solve for the transformed variables. The solutions is  x(t), y(t), and z(t) in the time domain.

For the given system:

dx/dt = y - 2z - t,

dy/dt = x + 2 + 2t,

dz/dt = x - y - 2.

Applying the Laplace transform to each equation, we obtain:

sX(s) - x(0) = Y(s) - 2Z(s) - 1/s^2,

sY(s) - y(0) = X(s) + 2/s + 2/s^2,

sZ(s) - z(0) = X(s) - Y(s) - 2/s.

Since x(0) = y(0) = z(0) = 0, we can simplify the equations:

sX(s) = Y(s) - 2Z(s) - 1/s^2,

sY(s) = X(s) + 2/s + 2/s^2,

sZ(s) = X(s) - Y(s) - 2/s.

We can now solve these equations to find X(s), Y(s), and Z(s) in terms of the Laplace variables. After finding the inverse Laplace transform of each variable, we obtain the solutions x(t), y(t), and z(t) in the time domain.

Answer:

its  A & B, x<50

Step-by-step explanation:

atmost means till 50.

atleast means more than 50.

The number sentence that states that x is at most 50 is option B: x ≤ 50.

In mathematical notation, the symbol "≤" means "less than or equal to." So, x ≤ 50 translates to "x is less than or equal to 50."

This means that x can be any value that is less than 50 or exactly 50.

Option A (x < 50) would mean "x is less than 50," excluding the value 50 itself.

Option C (x = 50) would mean "x is equal to 50," but it doesn't include any values less than 50.

Option D (x > 50) would mean "x is greater than 50," excluding the value 50 itself.

Option E (x ≥ 50) would mean "x is greater than or equal to 50," which includes values greater than 50, but it doesn't allow any values less than 50.

So, the correct choice to state that x is at most 50 (including the value 50) is option B: x ≤ 50.

The y-intercept of the parabola is located at (0, -8).

The given expression represents a function f(x) of the independent variable x.

The function is quadratic, which means that it can be graphed as a parabola. The coefficient of the x^2 term, 2, is positive, so the parabola opens upwards. The vertex of the parabola can be found by using the formula -b/2a, where a and b are the coefficients of the x^2 and x terms, respectively. In this case, a = 2 and b = 6, so the vertex is located at:

x = -b/2a = -6/(2*2) = -3/2

To find the y-coordinate of the vertex, we substitute this value of x into the function:

f(-3/2) = 2(-3/2)^2 + 6(-3/2) - 8 = -11

Therefore, the vertex of the parabola is located at (-3/2, -11).

We can also find the x-intercepts of the parabola by setting f(x) = 0 and solving for x:

2x^2 + 6x - 8 = 0

Dividing both sides by 2, we get:

x^2 + 3x - 4 = 0

This quadratic equation can be factored as:

(x + 4)(x - 1) = 0

Therefore, the x-intercepts of the parabola are located at x = -4 and x = 1.

We can also find the y-intercept of the parabola by setting x = 0 in the function:

f(0) = 2(0)^2 + 6(0) - 8 = -8

Therefore, the y-intercept of the parabola is located at (0, -8).

By plotting the vertex, intercepts, and a few additional points, we can sketch the graph of the function f(x) = 2x^2 + 6x - 8
