The vertex of the parabola is at (-3, 0), and the parabola opens downward.

The given function g(x) = -(x + 3)^2 can be obtained from the basic graph of the quadratic function f(x) = x^2 by performing a set of transformations.

1. Reflection: The negative sign in front of the function, g(x) = -(x + 3)^2, reflects the graph across the x-axis, making it an upside-down parabola.

2. Horizontal translation: The term "x + 3" inside the parentheses represents a horizontal shift of 3 units to the left. This means the graph of g(x) is shifted three units to the left compared to the basic quadratic function f(x).

3. Vertical translation: The negative sign and the square term affect the vertical position of the graph. Since the square term is always positive, the entire graph is shifted vertically downward. In this case, the vertex of the parabola is at the point (-3, 0).

By applying these transformations to the basic quadratic graph, we can sketch the graph of the function g(x) = -(x + 3)^2 as follows:

```

No, the velocity vector v(t) of a curve r(t) is not always perpendicular to the acceleration vector a(t). To understand this concept, we first need to understand what these vectors are.

The velocity vector v(t) of a curve r(t) represents the rate of change of position of an object with respect to time. In other words, it tells us how fast an object is moving and in what direction. It is a tangent vector to the curve r(t) at any given point on the curve.

Answer:

each would take about 8 hours. all youd need to do is divide 100 kilo by 12 because thats how much he runs in one hour. so 100 kilometers per week would take 8.3, which is rounded to ~about~ 8

The true statement is Each treadmill session takes about 2 hours.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

He runs at a constant speed of 12 kilometers per hour for 5 days per week.

If he runs 100 kilometers per week

So, each day he runs

= 100 /5

= 20 Km

and, he runs 20 Km in

= 20 /12

= 1.666

= 2 hours approximately.

Hence, Each treadmill session takes about 2 hours.

The rate at which costs ascend throughout a given time is called Inflation Rate. For this present circumstance, the demand will move rightwards. It is option A.

The demand for loanable funds will shift right, and the supply of loanable funds will shift left if both suppliers and demanders in the loanable funds market suddenly anticipate an inflation rate of 4% instead of zero percent.

The market for loanable assets depicts how that getting occurs. The source of loans' available funds is saved. The demand for loanable funds is driven by borrowing.

The interaction between the demand for loans and the supply of savings determines both the real interest rate and the amount of money loaned. A moderate expansion of around 2% is really great for financial development. Customers are bound to purchase now instead of standing by when they anticipate that costs should rise.

The events are mutually exclusive events, so P(A|B) is 0.

In this question,

If two events are mutually exclusive, there is no chance that both events will occur. Being the intersection an operation whose result is made up of the non-repeated and common events of two or more sets, that is, given two events A and B, their intersection is made up of the elementary events that they have in common, then

⇒ A ∩ B = 0

Now the conditional probability, P(A|B) = \(\frac{P(A \cap B )}{P(B)}\)

⇒ \(\frac{0}{0.10}\)

⇒ 0.

Hence we can conclude that the events are mutually exclusive events, so P(A|B) is 0.

To find the total revenue function R(x), we need to integrate the marginal revenue function MR(x) with respect to x and then add the constant of integration C.

Given the marginal revenue function MR(x) = -0.6x + 35, we integrate as follows:

∫(MR(x)) dx = ∫(-0.6x + 35) dx = -0.3x^2 + 35x + C

So, the total revenue function is R(x) = -0.3x^2 + 35x + C.

The total revenue function is found by integrating the marginal revenue function. In this case, we have:

MR = -0.6x + 35

Integrating both sides with respect to x gives:

R(x) = -0.6x^2/2 + 35x + C

Simplifying, we get:

R(x) = -0.3x^2 + 35x + C

Since we don't know the value of C, we can use the information that the total revenue is 0 when x = 0 to find it. That is, we have:

R(0) = 0 = -0.3(0)^2 + 35(0) + C

Solving for C, we get:

C = 0

Therefore, the total revenue function is:

R(x) = -0.3x^2 + 35x

Answer:

x = 16

Step-by-step explanation:

Given:

Therefore, total marks = 15 × 6 = 90

To find the value of x, add up the individual marks:

12 + 16 + 14 + 13 + 19 + x = 74 + x

Now equate this to the total number of marks found previously:

74 + x = 90

Solve for x:

⇒ 74 + x - 74 = 90 - 74

⇒ x = 16

Therefore, the value of x is 16.

It is $20 / sqrt(46), which is approximately $2.9516. In this scenario, we have information about the average price of college math textbooks, which is $179, and the standard deviation, which is $20. Additionally, we are given a sample size of 46 textbooks.

To calculate the mean price of the sample, we simply use the average given, which is $179.

To determine the standard deviation of the sample mean, also known as the standard error, we divide the standard deviation of the population by the square root of the sample size. In this case, it is $20 / sqrt(46), which is approximately $2.9516.

The standard error allows us to estimate the variability of the sample mean and provides insights into the precision of our estimation.

Step-by-step explanation:

The total number of ways to assign employees to desks is 720 (6!), and the number of favorable outcomes is 144. Therefore, the probability is 144/720 = 1/5.

The total number of ways to assign six employees to six desks is 6! (6 factorial), which equals 720. Now we need to find the number of ways that the married couple will not have adjacent desks.

First, we can treat the married couple as one entity, which means we have 5 entities to assign to 6 desks. There are 6 possible ways to choose the position of the married couple in the row. For each of these positions, we can then assign the other 4 entities to the remaining 4 desks in 4! ways.

Therefore, the total number of ways to assign employees to desks without the married couple having adjacent desks is 6 x 4! = 144.

The probability of this happening is the number of favorable outcomes (144) divided by the total number of possible outcomes (720), which is 144/720 = 1/5.



The probability that the married couple will not have adjacent desks when six new employees are randomly assigned to six desks that are lined up in a row is 1/5.

We calculated this probability by first treating the married couple as one entity and then finding the number of ways to assign the remaining entities to the desks without the married couple being adjacent to each other. The total number of ways to assign employees to desks is 720 (6!), and the number of favorable outcomes is 144. Therefore, the probability is 144/720 = 1/5.

The measurement m angle Q and m angle R of Quadrilateral PQRS is 72°.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Area: base × height

Perimeter: 2 x (sum of lengths of adjacent sides)

Number of vertices: 4

Number of edges: 4

We are given that;

Angle P= 72

Since PQRS is a parallelogram, opposite angles are equal. So:

m∠Q = m∠P = 72°

Similarly,

m∠R = m∠S

Also, the sum of the angles of a parallelogram is 360°. Therefore:

m∠P + m∠Q + m∠R + m∠S = 360°

Substituting the given value, we get:

72° + 72° + m∠R + m∠S = 360°

Simplifying:

144° + m∠R + m∠S = 360°

m∠R + m∠S = 216°

Since PQRS is a parallelogram, opposite angles are equal, so:

m∠R = m∠P = 72°

Therefore,

m∠R = 72°

m∠Q = m∠P = 72°

So, the measures of parallelogram angles  Q and R are both 72°.

The value of 'c' in the 32^{2c} = 8^{c+7}\(32^{2c} = 8^{c+7}\) is, 3.

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents is only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

Given, An expression \(32^{2c} = 8^{c+7}\).

Now, To equate the exponents we have to change the bases to the same value.

Therefore, \(32^{2c} = 8^{c+7}\) ⇒ \((2^5)^{2c} = (2^3)^{c+7}\).

5(2c) = 3(c + 7).
