A scale factor of 1/3 for the transformation is discovered using proportions.

In accordance with the rule of three, a percentage is a component of a total amount.

If both the new and original dimensions are known, the scaling factor may be determined. A figure's scale factor can be calculated using the following simple formula: Dimension of the original shape minus the dimension of the new shape is the scale factor.

When applying the proportion to this situation, the scale factor of the transformation is 1/3 because each coordinate was multiplied by 3 throughout the transformation process.

The kinetic energy will the ball acquire from the bat is 2× 10² J

According to the question

Bat stays in contact for 5.0 X 10⁻³ and the ball travels at a speed of 2.0 X 10⁴.

An object's kinetic energy is the power it has as a result of motion. It is explained as the amount of effort required to move a mass-based body from rest to the indicated velocity.

The body keeps its kinetic energy, which it acquired during acceleration, unless its speed changes.

A mass m object moving at a speed v has kinetic energy 1/2 mv² according to classical mechanics.

Favg= -1/2 MV²

K= -1 2 ( 5.0 x 10⁻³)²

Unicode value of 66, which is the letter "B". Therefore, the correct answer to this question is option B: "B".

The terms you mentioned are related to the Unicode character encoding standard and the concept of evaluating expressions. When discussing the expression "A" + 1, it's essential to note that the Unicode value for the character "A" is 65.

The expression "A" + 1 is attempting to add a numerical value (1) to a character ("A"). In many programming languages, this operation is allowed, and the result would be based on the Unicode values of the characters involved. Since the Unicode value for "A" is 65, adding 1 to it would result in a new Unicode value of 66. Consequently, the evaluated expression would correspond to the character with the Unicode value of 66, which is the letter "B". Therefore, the correct answer to this question is option B: "B".

Answer:

Ans: Rs 181.44.

Step-by-step explanation:

At time t = 10 minutes, there would be approximately 16.67 grams of salt in the tank.

The number of grams of salt in the tank at time t can be found by considering the rate of salt entering and leaving the tank.

Initially, the tank contains 20 grams of salt in 360 liters of fluid.

Every minute, 6 liters of pure water are pumped into the tank, while an equal amount of the well-mixed solution is pumped out.

Since the rate of water entering and leaving the tank is the same, the volume of fluid in the tank remains constant at 360 liters.

Therefore, the concentration of salt in the tank is constant over time.

To find the number of grams of salt in the tank at time t, we can use the formula:

a(t) = (20 grams / 360 liters) * (360 liters - 6 liters * t)

where t is the time in minutes.

Let's work through an example:

If t = 10 minutes, then the number of grams of salt in the tank at that time would be:

a(10) = (20 grams / 360 liters) * (360 liters - 6 liters * 10)

Simplifying this expression:

a(10) = (20 grams / 360 liters) * (360 liters - 60 liters)

a(10) = (20 grams / 360 liters) * 300 liters

a(10) = (20 * 300) / 360

a(10) = 6000 / 360

a(10) ≈ 16.67 grams

Therefore, at time t = 10 minutes, there would be approximately 16.67 grams of salt in the tank.

The probability that the doors were left open given that a garage was robbed is 0.625 or 62.5%.

To find the probability that the doors were left open given that a garage was robbed, we can use Bayes' theorem.
Let's assign some variables to the given information:
- Let O represent the event that the doors were left open.
- Let R represent the event that the garage was robbed.
We are given the following probabilities:
- P(O) = 1/4 (since one-fourth of the residents leave their garage doors open)
- P(R|O) = 5% or 0.05 (since 5% of the garages with open doors will have something stolen)
- P(R|not O) = 1% or 0.01 (since 1% of the garages with closed doors will have something stolen)
We want to find P(O|R), the probability that the doors were left open given that a garage was robbed.
Using Bayes' theorem, we have:
P(O|R) = (P(O) * P(R|O)) / (P(O) * P(R|O) + P(not O) * P(R|not O))
Substituting the given probabilities, we get:
P(O|R) = (1/4 * 0.05) / (1/4 * 0.05 + 3/4 * 0.01)
Simplifying the equation, we have:
P(O|R) = 0.0125 / (0.0125 + 0.0075)
P(O|R) = 0.0125 / 0.02
P(O|R) = 0.625
Therefore, the probability that the doors were left open given that a garage was robbed is 0.625 or 62.5%.

In this case, Christopher divides the athletes into groups of varsity and junior varsity, which creates the strata. The type of sampling used in this scenario is stratified sampling.

Stratified sampling is a sampling method where the population is divided into homogeneous subgroups or strata, and individuals are randomly selected from each stratum in proportion to their representation in the population. In this case, Christopher divides the athletes into groups of varsity and junior varsity, which creates the strata.

By randomly selecting a proportionate number of individuals from each group, Christopher ensures that both varsity and junior varsity athletes are represented in the sample, maintaining the proportional representation of each group in the population. This method allows for more accurate and representative results by capturing the characteristics of both groups separately.

The evaluated value of the function f(x) = 3e^(-x+2) - 2 for x = 4 is approximately 0.045.

To evaluate the function, we substitute x = 4 into the given equation and simplify the expression. Plugging in x = 4, we have f(4) = 3e^(-4+2) - 2. Simplifying further, we get f(4) = 3e^(-2) - 2.

Using the approximate value of e as 2.71828, we can calculate the evaluated value. Evaluating 3e^(-2) - 2, we find that f(4) is approximately equal to 0.045 when rounded to three decimal places.

Therefore, when x is 4, the function f(x) = 3e^(-x+2) - 2 evaluates to approximately 0.045.

Step-by-step explanation:

I'm not sure what you need help with, since what you have written down is correct. However, if you are looking for an explanation, here it is:

x + 5 < -2

To solve for x, we have to get x on one side by itself. Whatever you do to one side, you have to do to the other. Let's get rid of 5 to get x by itself.

x + 5 < -2    (Subtract 5 from both sides)

x < -7

Perfect! Basically what this is saying, is that all the values x can equal have to be less than -7. The sign < means less than.

For the signs < (less than) and > (greater than), we use an open circle.

For the signs ≤ (less than or equal to) and ≥ (greater than or equal to), we use a closed circle.

This is why we use an open circle for this example since x is LESS THAN -7.

The arrow is pointing to the left because these numbers are less than -7.

Answer: 1.25 inches

Step-by-step explanation:

20 miles ·  \(\frac{1 in}{16 miles}\) = \(\frac{5}{4}\) inches = 1.25 inches

Explanation and Steps:

So if 1 inch is 16 miles and we have to figure out how many inches is 20 miles, we should find how many inches is 1 mile to start. To do that, we will do 1 divided by 16, which is 0.0625. So 1 mile is 0.0625 inches.

Now let's check to see if the math was correct. Take 0.0625 and multiply it by 16. If you get 1, it's correct, if not, it's incorrect. (0.0625)(16)=1. That is correct! So now that we know 0.0625 inch is equal to 1 mile, we can find how many inches is 20 miles by multiplying 0.0625 and 20. (0.0625)(20)=1.25

1.25 inches on the map represents 20 miles.

Work (Answer):

1in=16mi

1in/16mi=0.0625in/mi

(0.0625in/mi)(20mi)=1.25in

we have

cos(90-θ)=Cosθ

so

ratio of cosθ is BC/CA

Step-by-step explanation: The solution to this system of equations will be where the two lines on the graph intersect with each other.

Notice that both of them intersect to the left of the y-axis which means our x - coordinate must be negative.

They also intersect above the x-axis so our y-coordinate must be positive.

So the only option with a negative x-coordinate

and a positive y-coordinate is (-1/4, 3/4).
