Answer:

\(\Huge \boxed{\mathrm{61.22 \ m}}\)

Step-by-step explanation:

A stone is thrown downward straightly with the velocity of 20 m/s and it reaches the ground at the velocity of 40 m/s. What will be the height of building? (Question)

The initial velocity ⇒ 20 m/s

The final velocity ⇒ 40 m/s

We can apply a formula to solve for the height of the building.

\((V_f)2 - (V_i)^2 =2gh\)

\(V_f = \sf final \ velocity \ (m/s)\)

\(V_i = \sf initial \ velocity \ (m /s)\)

\(g = \sf acceleration \ due \ to \ gravity \ (m/s^2 )\)

\(h = \sf height \ (m)\)

Plugging in the values.

Acceleration due to gravity is 9.8 m/s².

\((40)^2 - (20)^2 =2(9.8)h\)

Solve for \(h\).

\(1600 - 400 =19.6h\)

\(1200 =19.6h\)

\(\displaystyle h=\frac{1200}{19.6}\)

\(h= 61.22449\)

The height of the building is 61.22 meters.

The hexadecimal system numbering system is base 16; in other words, 16 numerals are used to express any given number.

In this system, 16 numerals are used to represent any given number. The numerals used in this system are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F, where A represents 10, B represents 11, and so on, up to F, which represents 15.

This system is commonly used in computer science, as it is more compact than the decimal system, and allows for easier conversion between binary and decimal systems. In the hexadecimal system, each digit represents a power of 16, just as each digit in the decimal system represents a power of 10.

The z-score is -5, which indicates that the sample proportion of 40% is 5 standard deviations below the population proportion of 64%.

To calculate the z-score, we first need to determine the standard deviation of the population. Unfortunately, the question doesn't provide us with that information, so we'll have to make an assumption.

Let's assume that the standard deviation of the population is 0.05 (or 5%). This is a common assumption when the population standard deviation is unknown.

Using this assumption, we can calculate the standard error of the sample proportion (the proportion of people in our sample who believe the election was rigged):

standard error = sqrt((p * (1 - p)) / n)

where p is the proportion from the population (0.64) and n is the sample size (100).

standard error = sqrt((0.64 * (1 - 0.64)) / 100) = 0.0498

Next, we can calculate the z-score:

z = (sample proportion - population proportion) / standard error

z = (0.40 - 0.64) / 0.0498 = -4.82

So the z-score is -4.82. This means that our sample proportion is 4.82 standard errors below the population proportion. In other words, our sample result is highly unlikely to have occurred by chance if the population proportion is really 0.64.

We can conclude that the surface is an ellipsoid, as it extends in the radial direction and forms a full loop when varying the angular coordinates.

The equation provided is:

ρ²(sin²(φ)sin²(θ) + cos²(φ)) = 25

Let's analyze the equation step by step:

1. Observe that the equation is given in spherical coordinates (ρ, θ, φ).
2. Notice that the equation can be rearranged as follows:

ρ² = 25 / (sin²(φ)sin²(θ) + cos²(φ))

3. Since the equation is written in terms of ρ², this suggests that the surface is a function of ρ.

4. Now, let's try to identify the surface shape. We can do this by examining the equation's behavior under different values of θ and φ.

- If we fix θ and vary φ between 0 and π, we can see that ρ changes accordingly, so the shape extends in the radial direction.
- If we fix φ and vary θ between 0 and 2π, the shape will extend in the circular direction, forming a full loop.

Given these observations, we can conclude that the surface is an ellipsoid, as it extends in the radial direction and forms a full loop when varying the angular coordinates.

The missing entries are the following y-intercept: (0, 25) and x-intercept: (5, 0). The Axis of symmetry is \(x = 5\) and Vertex: (5, 0).

1. To find the y-intercept, substitute \(x = 0\) into the equation:

  \(y = (0)^2 - 10(0) + 25 = 25\).

  Therefore, the y-intercept is (0, 25).

2. To find the x-intercepts, set \(y = 0\) and solve for x:

  \(0 = x^2 - 10x + 25\).

  This equation can be factored as \((x - 5)^2 = 0\).

  Taking the square root of both sides gives \(x - 5 = 0\).

  Solving for x, we get \(x = 5\).

  Therefore, the x-intercept is (5, 0).

3. To find the axis of symmetry, use the formula \(x = -\frac{b}{2a}\) where the equation is in the form \(y = ax^2 + bx + c\).

  In this case, \(a = 1\) and \(b = -10\).

  Substituting these values into the formula gives \(x = -\frac{-10}{2(1)} = 5\).

  Therefore, the axis of symmetry is \(x = 5\).

4. To find the vertex, substitute \(x = 5\) into the equation:

  \(y = (5)^2 - 10(5) + 25 = 0\).

  Therefore, the vertex is (5, 0).

Answer:

Step-by-step explanation:

Since ∆ ABC is a triangle the sum of it's angles add up to 180°

In order to find x we must first find \(\angle\) AED

Let \(\angle\) AED = E

To find \(\angle\) AED add up all the angles in the triangle and equate it to 180°

That's

35 + 90 + E = 180

125 + E = 180

E = 180 - 125

E = 55°

E and x lie on a straight line

So we have

x + 55 = 180°

x = 180 - 55

The correct choice is: OA. The solution set is {π/4}. To summarize, the correct choice is: OA. The solution set is {π/4}.

To solve the equation 3cot(x) + 4 = 7 over the interval [0, 2x), we'll first isolate the cotangent term and then find the values of x that satisfy the equation.

Let's start by subtracting 4 from both sides of the equation:

3cot(x) = 7 - 4

3cot(x) = 3

Now, divide both sides of the equation by 3:

cot(x) = 1

The cotangent function is the reciprocal of the tangent function, so cot(x) = 1 is equivalent to tan(x) = 1.

Now, we need to find the values of x in the interval [0, 2x) that satisfy tan(x) = 1.

The tangent function is positive in the first and third quadrants. In the first quadrant, the tangent function is equal to 1 at π/4 radians. In the third quadrant, it is also equal to 1 at 5π/4 radians.

Since we are looking for solutions in the interval [0, 2x), we can consider the solution π/4.

Alternative hypothesis may be one-sided or two-sided.

b) alternative hypothesis.

In statistical hypothesis testing, the alternative hypothesis is one of the suggested propositions in the hypothesis test. In general, the purpose of a hypothesis test is to demonstrate that, under the given conditions, there is sufficient evidence to support the believability of an alternate hypothesis rather than the test's exclusive statement (null hypothesis). Because it is based on a review of the literature and previous studies, it is usually congruent with the research hypothesis. However, the research hypothesis is sometimes congruent with the null hypothesis.

In statistics, alternative hypotheses are frequently denoted as Hₐ or H₁. In a statistical hypothesis test, hypotheses are developed to be compared.

In the field of inferential statistics, two competing hypotheses can be compared using explanatory and predictive power.

For the given problem, the integral of \(\frac{1}{\sqrt{a^2-x^2}}\)  is  \($\sin^{-1}\frac{x}{a} + C$.\)

A mathematical notion that depicts the area under a curve or the accumulation of a quantity over an interval is known as an integral. Integrals are used in calculus to calculate the total amount of a quantity given its rate of change.

The process of locating an integral is known as integration. Finding an antiderivative (also known as an indefinite integral) of a function, which is a function whose derivative is the original function, is what integration is all about. The antiderivative of a function is not unique since it might differ by an integration constant.

For given problem,

\($\int \frac{1}{\sqrt{a^2-x^2}} dx$\)

Let \($x = a \sin\theta$\) , then \($dx = a \cos\theta d\theta$\)

\($= \int \frac{1}{\sqrt{a^2-a^2\sin^2\theta}} a\cos\theta d\theta$\)

\($= \int \frac{1}{\sqrt{a^2\cos^2\theta}} a\cos\theta d\theta$\)

\($= \int d\theta$\)

\($= \theta + C$\)

The first step is determine Martin's weight in 1970.

The equation that would be used to determine this value is:

Weight in 2000 = weight in 1970 + (increase per year x difference in years)

1.40w = w + [2 x (2000 - 1970)]

1.40w = w + (2 x 30)

0.40w = 60

w = 60 / 0.4

w = 150

Weight in 2015 = 150 x 1.40 = 210

Weight in 2015 = 150 + [2 x (2015 - 1970)]

150 + [2 x 45]

150 + 90
