Answer:

Z.

Step-by-step explanation:

A function must pass the Vertical Line Test. No 2 y-values can have the same x-values. Since the first 3 graphs fail to pass the vertical line test, our answer is Z.

The largest interval I over which the solution is defined is (-∞, ∞).               I = (-∞, ∞)

To solve the given initial-value problem, we can use the method of separation of variables as follows:
1. Separate the variables by moving all terms with y to the left side of the equation and all terms with x to the right side:
y/y' = ex/x
2. Integrate both sides of the equation with respect to their respective variables:
∫y/y' dy = ∫ex/x d
ln(y) = ex + C
3. Solve for y:
y = e^(ex + C)
4. Use the initial condition y(1) = 9 to find the value of C:
9 = e^(e + C)
C = ln(9) - e
5. Substitute the value of C back into the equation for y:
y = e^(ex + ln(9) - e)
6. Simplify the equation:
y = 9e^(ex - e)
7. The largest interval I over which the solution is defined is (-∞, ∞), since there are no restrictions on the values of x or y therefore, the solution to the initial-value problem is y(x) = 9e^(ex - e) and the largest interval I over which the solution is defined is (-∞, ∞).

Answer is

Answer:

Options (1), (2) and (5) are true.

Step-by-step explanation:

Option (1). m∠1 = (2x + 10)°

lines c and d are the parallel lines and t is a transverse.

Therefore, m∠1 = (2x + 10)° [corresponding angles]

This option is true.

Option (2). m∠3 = 87°

Since ∠3 and angle having measure equal to 87° are the vertical angles therefore, both the angles will be equal in measure.

This option is true.

Option (3). m∠2 = (2x + 10 + 5x - 1)°

m∠2 = (5x - 1)° [Since both the angles are interior alternate angles]

Therefore, this option is not true.  

Option (4). m∠1 + m∠2 = m∠3

(5x - 1) + (2x + 10) + 87 = 180° [Sum of liner angles at a point is 180°]

7x + 96 = 180

7x = 180 - 96

x = \(\frac{84}{7}\)

x = 12

Therefore, m∠1 = (2x + 10) = 34°

                 m∠2 = (5x - 1) = 59°

                 m∠3 = 87°

For the given relation,

m∠1 + m∠2 = m∠3

34 + 59 = 87

93 = 87

Not true.

Therefore, this option is not correct.

Option (5). 87 + 2x + 10 + 5x - 1 = 180°

True.

Since these angles are the linear angles so the sum of all angles = 180°

Therefore, the given option is correct.

Options (1), (2) and (5) are the true.

a. The mean will not change. When considering the effect of sample size on the mean of the sampling distribution,

it's important to understand the concept of the Central Limit Theorem (CLT) and the properties of sampling distributions.

The Central Limit Theorem states that for a large enough sample size, the sampling distribution of the sample mean will be approximately normally distributed, regardless of the shape of the population distribution. Additionally, the mean of the sampling distribution will be equal to the population mean.

As the sample size increases, the sampling distribution becomes more representative of the population distribution, and the variability of the sample means decreases. However, the mean of the sampling distribution remains the same as the population mean.

This is an important property of the Central Limit Theorem. It means that increasing the sample size does not change the mean of the sampling distribution. The mean of the sampling distribution is solely determined by the population mean, not the sample size.

To put it simply, the mean of the sampling distribution represents the average of all possible sample means that could be obtained from a population. It is not influenced by the sample size but rather reflects the underlying population parameter.

Therefore, when the sample size increases, the mean of the sampling distribution will not change. It will remain the same as the population mean.

The solution to the initial value problem is:

f(x) = -5/x - x³/15 + 76/15

The solution to the initial value problem can be found by integrating the given differential equation and applying the initial condition.

Integrating both sides of the differential equation, we have:

∫f '(x) dx = ∫(5/x² − x²/5) dx

Using the power rule for integration, we get:

f(x) = -5/x - x³/15 + C

Now, we can apply the initial condition f(1) = 0:

0 = -5/1 - 1³/15 + C

0 = -5 - 1/15 + C

C = 5 + 1/15

C = 76/15

The required proportional relationship is given a p = 3/4 m. Optio B is correct.

Given that,
Ben reads 6 pages of a book in 8 minutes, 9 pages in 12 minutes, and 30 pages in 40 minutes. If m represents the number of minutes and p represents the number of pages.

proportionality is defined as between two or more sets of values, and how these values are related to each other in a sense are they directly proportional or inversely proportional to each other.

As here, in the question there is no mention of any kind of intercept thus the relationship explained is the proportionality relation between the number of pages P and the number of minutes m.
According to the question,
P ∝ M
P =Km - - - - - (1)
Put one ordered pair from the given,

K = 3 / 4
Put K in equation 1.
P = 3 / 4 m

The midpoint formula and the normal vector of the plane can be used to determine the equation of the plane that contains all points equidistant from the points (1,0,-2) and (3,4,0).

Given by: The midpoint of the two points is:

M = [(1 + 3)/2, (0 + 4)/2, (-2 + 0)/2] = (2, 2, -1) (2, 2, -1)

The following vector runs between the two points:

V = (3 - 1, 4 - 0, 0 - (-2)) = (2, 4, 2) (2, 4, 2)

The cross product of two non-parallel plane vectors yields the normal vector to the plane. The midpoint M to a point on the plane is one such vector, while the other is the vector V. Consider the point P = (2, 2, -1) + t(2, 4, 2) as an illustration, where t is a scalar.

The normal vector is then provided by:

N = V x (P - M) = (2, 4, 2) x (2t, 4t, 2t -1), which equals (12t, -8t, 4t + 2)

The point-normal form, which makes use of the normal vector N and the point M, can be used to determine the equation for the plane:

(x - 2) * 12t = (y - 2) * -8t = (z + 1) * 4t + 2

The final equation of the plane is obtained by multiplying both sides of the equation by t and setting t 0.

12(x - 2) = -8(y - 2) = 4(z + 1) + 2

Answer: f(x) = -1/2(x+3)

Example: g(x) = -1/2(-x-3)

This function is a dilation and a reflection of the parent function f(x) because when graphed, the two functions have the same shape but are reflected over the y-axis and are half the size of the original.

Supplementary angles are angles that add up to 180 degrees.

Angle 1 = x

Angle 2 = x + 10

Since they are supplementary, we can set then equal to 180

x + x + 10 = 180

Combine like terms

2x + 10 = 180

Subtract 10 from both sides

2x = 170

Divide both sides by 2

x = 85

Angle 1 = 85 degrees

Angle 2 = 85 + 10 = 95 degrees

Answer:

w = 300 + 0.15x

Step-by-step explanation:

Let x = weekly sales

Since there is a fixed remuneration of $300, that will be a constant in the linear equation

15% = 15/100 = 0.15 in decimal

15% commission on x dollars of sales = 0.15x

Therefore total weekly pay, w, in terms of x

w = 300 + 0.15x

Step-by-step explanation:

Simplifying the expression gives 36x^2 - 82x - 10 = 0

Given the expression;

4x-5/3+2x=7+2/9x+2

\(\frac{4x - 5}{3 + 2x} = \frac{9}{9x + 2}\)

Cross multiply

\(4x - 5( 9x + 2) = 9 (3 + 2x)\)

Expand the bracket

\(36x^2 + 8x - 45x - 10 = 27x + 18x\)

Collect like terms

36x^2 + 8x - 45x - 27x - 18x = 0
