The maximum range will be achieved when the angle is 45°, which is half of the full angle (90°) of a right angle.

The maximum angle (with respect to the level ground) that you can launch a projectile at and have its total distance from you never decrease while it is in flight, assuming no air resistance is 45 degrees.

Projectile motion is the motion of an object that is projected into the air and then moves under the force of gravity. Objects that are propelled from the ground into the air are referred to as projectiles.

The motion of such objects is called projectile motion. When objects are thrown at an angle to the horizontal plane, the curved path they travel on is referred to as a parabola.

This is due to the fact that the projectile is influenced by two forces: the initial force that launches the projectile and the force of gravity that pulls it back down.

In order to find out the maximum angle, the path of the projectile must be observed. The range of a projectile is defined as the horizontal distance it covers from the point of launch to the point of landing.

The range is calculated using the following formula:

R = (V²/g) * sin(2θ)

where

R is the range of the projectile,

V is the initial velocity of the projectile,

g is the acceleration due to gravity, and

θ is the angle at which the projectile was launched.

The maximum range will be achieved when the angle is 45°, which is half of the full angle (90°) of a right angle.

Answer:

f(5)=26

Step-by-step explanation:

hello :

f(n)=f(n-1)+4   means :  f(n)-f(n-1)=4  (comon diference for arithm - sequence)

so : f(n) =f(1)+(n-1)×4

f(n) =10+(n-1)×4

f(n) = 4n+6

f(5) = 4(5)+6 =26

If the target behavior is recorded whenever it occurs at any point within the scoring interval, the measurement procedure used is called continuous recording or event recording. This method involves observing and recording each instance of the behavior without considering its duration or intensity.

Continuous recording is typically used when the target behavior is discrete and occurs relatively infrequently or has a short duration. With this measurement procedure, each occurrence of the behavior is recorded as a separate event, regardless of when it starts or ends within the scoring interval. Examples of behaviors that can be measured using continuous recording include vocalizations, hand clapping, or instances of aggression.

Continuous recording provides a comprehensive account of the frequency or rate at which the behavior occurs, allowing for a detailed analysis of its occurrence patterns. This method is particularly useful when a precise count of behavior instances is needed and when the duration or intensity of the behavior is not a focus of measurement.

To determine the electric field in the region at the coordinates (3,4,5), we need to calculate the negative gradient of the electric potential function V(x, y, z) = x^2 + xy^2 + 2yz.

The electric field (E) is the negative gradient of the electric potential (V), given by E = -∇V, where ∇ represents the gradient operator.

Taking the partial derivatives of V with respect to x, y, and z, we have:

∂V/∂x = 2x + y^2

∂V/∂y = 2xy + 2z

∂V/∂z = 2y

Substituting the coordinates (3,4,5) into these partial derivatives, we get:

∂V/∂x = 2(3) + (4^2) = 2(3) + 16 = 6 + 16 = 22

∂V/∂y = 2(3)(4) + 2(5) = 24 + 10 = 34

∂V/∂z = 2(4) = 8

Therefore, the electric field at the coordinates (3,4,5) is given by E = (-22, -34, -8).

The electric field at the coordinates (3,4,5) in the given region, where the electric potential function is V(x, y, z) = x^2 + xy^2 + 2yz, is (-22, -34, -8). The negative gradient of the potential function gives us the electric field, and the coordinates are substituted to calculate the partial derivatives of the potential function with respect to x, y, and z.

The sampling method described, where every 5th person on a list is chosen, is known as systematic sampling.

Systematic sampling is a sampling method where the researcher selects every k-th element from a population or a list. In this case, the researcher chooses every 5th person on the list.

Here's how systematic sampling works:

1. The population or list is ordered in a specific way, such as alphabetical order or ascending/descending order based on a specific criterion.

2. The researcher defines the sampling interval, denoted as k, which is the number of elements between each selected element.

3. The first element is randomly chosen from the first k elements, usually by using a random number generator.

4. Starting from the randomly chosen element, the researcher selects every k-th element thereafter until the desired sample size is reached.

Systematic sampling provides a more structured and efficient approach compared to simple random sampling, as it ensures coverage of the entire population and reduces sampling bias. However, it is important to note that systematic sampling assumes that the population is randomly ordered, and if there is any pattern or periodicity in the population list, it may introduce bias into the sample.

In summary, the sampling method described, where every 5th person on a list is chosen, is known as systematic sampling. It is a type of non-random sampling method, as the selection process follows a systematic pattern rather than being based on random selection.

The given equation is:

375 = x - 28

To solve the equation:

Collect like terms

The -28 crosses the equality sign to the left and becomes 28

The equation then becomes:

375 + 28 = x

x = 403 (correct answer)

The students error is that when he collected like terms, he did not change the "-" sign in -28 to +

He did 375 - 28 = x

Answer:

20a^2+68a

Step-by-step explanation:

The question is asking for Area: a=length*width.

In this case, length= 5a+17     width=4a

You multiply 4a to 5a+17 and you get 20a^2+68a

Area of the rectangular garden is given by (20a²+68a)square feet.

" Area is defined as total space occupied by any two dimensional object enclosed in it."

Formula used

Area of a rectangle = length × width

According to the question,

Given,

Length of the rectangular garden = 5a + 17 feet

Width of the rectangular garden = 4a feet

Substitute the value in the formula we get,

Area of the rectangular garden = (5a +17) (4a)

                                                    = 20a² +68a

Hence, area of the rectangular garden is given by (20a²+68a)square feet.

There is enough evidence to suggest p>0.5

What is hypothesis in statistics?

A type of statistical analysis called hypothesis testing involves testing your presumptions regarding a population parameter. It is used to estimate the relationship between 2 statistical variables.

Thus, a hypothesis is a set of possible explanations or resolutions applicable to a situation. In other words, the hypotheses pose different scenarios in which the aim is to explain the origin and eventual resolution of the problem.

Let's discuss few examples of statistical hypothesis from real-life -

We are testing :

H0: p <= 0.5

H1: p > 0.5

Test statistic:

Z = [(364/562) - 0.5] / √[0.5(1-0.5)] / 562

= 7.00

P-value = P(Z>7.00) = 0.0000

Answer:

  y = -1

Step-by-step explanation:

The slope formula tells you the slope is ...

  m = (y2 -y1)/(x2 -x1)

  m = (-1 -(-1))/(5 -3) = 0/2 = 0

We can find the y-intercept using the first point:

  b = y -mx

  b = -1 -0·3 = -1

Then the slope-intercept form is ...

  y = mx + b

  y = 0·x -1

  y = -1 . . . . . simplified

Of course, you can bypass all of that when you realize the two y-values are the same, so the line is a horizontal line with y equal to that value.

"Yes, the Mean Value Theorem can be applied."

The Mean Value Theorem states that if a function is continuous on the closed interval [a,b] and differentiable on the open interval (a,b), then there exists a point c in the interval (a,b) such that the derivative at c is equal to the average rate of change of the function over [a,b].

Given the function f(x) = x / (x - 10) on the interval [1,9], let's examine its continuity and differentiability.

The function has a discontinuity at x = 10 because the denominator becomes zero. However, this point is not within the given interval [1,9]. Thus, the function is continuous on the interval [1,9].

Now, let's check for Mean Value Theorem . We can find the derivative of the function: f'(x) = (x - 10 - x) / (x - 10)^2 = -10 / (x - 10)^2. The derivative exists for all points except x = 10. Since this point is not in the interval (1,9), the function is differentiable on (a,b).

Therefore, the Mean Value Theorem can be applied to f(x) = x / (x - 10) on the closed interval [1,9]. So the answer is: "Yes, the Mean Value Theorem can be applied."
