Answer:

Step-by-step explanation:

The 30-60-90 triangle rule states that the hypotenuse is equal to the short leg times 2. So 4 x 2 = 8.

The flight-path angle is equal to 45' when v =90' on all parabolic trajectories is proved using the trajectories.

Using trajectories equation :

r = p/(1+cosv)     at v= 90 degrees

r{90} = p/ (1+cos90°)

        = p       since, cos 90 = 0

also, v= √2mue/r

        v{90} = √2mue/p

where r {90}  and v{90} are radius and velocity at v = 90 degrees.

the angular momentum is given as , h = r.v cosФ

and at periapsis on a parabolic trajectory , rp = p/2

  v{90} = √2mue/p

applying the concentration of angular momentum,

rp.vp = r90.v90.cosФ

p/2.√2mue/p = p.√2mue/p.cosФ

cos Ф = 1/√2

therefore,Ф = 45

hence the flight-path angle is equal to 45' when v =90' on all parabolic trajectories is proved.

x = 2

Answer:

4ounces of water must be evaporated from 28 ounces of a 6% salt solution to make a 7% salt solution.

Given that,

We have to find how much water must be evaporated from 28 ounces of a 6% salt solution to make a 7% salt solution.

We know that,

Let us take x as ounces of water evaporated to make 7% of salt solution.

We have 28 ounces of 6% of salt solution.

For 7% salt solution we get,

\(\frac{28\times 6}{28-x} = 7\)

7(28-x) = 168

196 - 7x = 168

7x = 196-168

7x = 28

Dividing 7 on both sides,

x = 4 ounces.

Therefore, 4 ounces of water evaporated to make 7% of salt solution.

So, the area of the parallelogram with corner P1 and adjacent sides P1P2 and P1P3 is √10 square units.

To find the area of the parallelogram with corner P1 and adjacent sides, P1P2 and P1P3, using cross product method. Given, P1 = (0, 0, 0), P2 = (3, 3, 4), and P3 = (0, -1, -1).

Then, The area of the parallelogram is square units

We are given three points P1, P2, and P3 and we need to find the area of the parallelogram with corner P1 and adjacent sides P1P2 and P1P3.

The formula for the area of a parallelogram in terms of vectors is given by:

Area of parallelogram = ||a × b||,

where a and b are vectors representing the adjacent sides of the parallelogram.

To find the area of the parallelogram, we need to find the vectors P1P2 and P1P3.

The vector representing the side P1P2 is given by:

P1P2 = P2 - P1 = (3, 3, 4) - (0, 0, 0) = (3, 3, 4)

The vector representing the side P1P3 is given by:

P1P3 = P3 - P1 = (0, -1, -1) - (0, 0, 0) = (0, -1, -1)

Now, we can find the area of the parallelogram as follows:

Area of parallelogram = ||P1P2 × P1P3||

We find the cross product of P1P2 and P1P3 as follows:

P1P2 × P1P3 = (3, 3, 4) × (0, -1, -1)

P1P2 × P1P3 = (3 × (-1) - 4 × (-1), 4 × 0 - 4 × 0, 3 × 0 - 3 × (-1))

P1P2 × P1P3 = (-1, 0, 3)

The magnitude of the cross product is given by:

||P1P2 × P1P3|| = √((-1)² + 0² + 3²) = √10

Therefore, the area of the parallelogram is:

Area of parallelogram = ||P1P2 × P1P3||

Area of parallelogram = √10 square units.

The missing angle for x by the measures add up to 90° is 53°

Complementary angles are pairs of angles whose measures add up to 90°. In this problem, we are given two angles, one of which measures 37°, and the other of which has an unknown measure that we will call x. We are also told that these angles are complementary, which means that their measures add up to 90°.

So, we can set up an equation to represent this relationship:

37 + x = 90

We can simplify this equation by subtracting 37 from both sides:

x = 90 - 37

x = 53

Now we know that the measure of the second angle is 53°. But we can go further and solve for x to get a more complete solution.

In the problem statement, we are also given an expression for the second angle in terms of x:

5x + 3

We know that this angle measures 53°, so we can set up another equation to represent this relationship:

5x + 3 = 53

We can solve for x by first subtracting 3 from both sides:

5x = 50

Then, we can divide both sides by 5 to isolate x:

x = 10

Now we know that x has a value of 10, and we can substitute this value back into the expression for the second angle to find its measure:

= 5x + 3

= 5(10) + 3 = 53

Therefore, the missing angle is 53°, and x has a value of 10.

Step-by-step explanation:

Angles  ∡DBE ≅ ∡ACD= 3x  reason - angles with parallel arms

Angles ∡ADC and ∡ADB=95° are supplemental angles which means

∡ADC + ∡ADB=180° => ∡ADC = 180° - ∡ADB= 180°-95°= 85°

In the triangle we have ∡ADC + ∡ACD + ∡CAD = 180° =>

85 + 3x + 2x = 180 => 85 + 5x = 180 => 5x= 180-85 => 5x=95

x=95/5 => x=19°

If there are 20 blondes in a class, 25 Brunettes, and 5 Redheads in a class, the proportion of the class that is blonde is 0.40 and the probability that someone in the class in blonde is 0.60.

There are 50 people in the class

There proportion is given by:

20/50, 25/50, 5/50: 40%, 50%, 10%

0.40 is blonde and 0.60 probability

Probability represents the chances of some event happening. It is theoretical. Proportion summarizes how frequently some event actually happened. Let us consider an example:

If we flip a fair coin, the probability that it will land on heads is 0.5 or 50%.

However, if we flip a fair coin 20 times then we can actually count the proportion of times it landed on heads. For example, perhaps it landed on heads in 60% of the flips.

The probability of landing on heads is theoretical, but the proportion of times the coin landed on heads is empirical – we could actually count the proportion.

To calculate the margin of error for the survey, we need more information about the sample size.

To determine the margin of error, we need to consider the sample size and the proportion of respondents in favor of the plan. In this case, we know that 70% of the 130 surveyed residents support the plan. The margin of error is calculated using the formula: Margin of Error = Critical Value * Standard Error. The critical value depends on the desired confidence level. At a 95% confidence level, the critical value is approximately 1.96.

The standard error is calculated using the formula: Standard Error = sqrt((p * (1-p)) / n) where p is the proportion of respondents in favor of the plan (70% or 0.7 in this case), and n is the sample size (130 residents in the survey). Using these values, we can calculate the margin of error:Standard Error = sqrt((0.7 * (1-0.7)) / 130) ≈ 0.038, Margin of Error = 1.96 * 0.038 ≈ 0.075. The margin of error is approximately 0.075, expressed as a decimal. To convert it to a percentage, we multiply by 100, yielding a margin of error of approximately 7.5% to the nearest tenth.

Therefore, at a 95% confidence level, the margin of error for this survey is approximately 7.5%. This means that the estimated proportion of residents in favor of the plan could vary by up to 7.5% in either direction due to sampling variability.

The margin of error for the 99% confidence interval for the population mean of grass seed germination periods is approximately 3.374 days.

To find the margin of error for the confidence interval for the population mean with a 99% confidence level for germination periods of grass seed, follow these steps:

1. Identify the given information:
- Sample size (n) = 21
- Sample mean (x) = 34 days
- Population standard deviation (σ) = 6 days
- Confidence level = 99%

2. Determine the appropriate z-score for the 99% confidence level:
- Since the confidence level is 99%, we need to look for the z-value that corresponds to 0.005 in the z-table (because 1 - 0.99 = 0.01, and 0.01/2 = 0.005).
- z0.005 = 2.576

3. Calculate the standard error of the mean (SEM):
- SEM = σ/√n = 6/√21 = 1.31

4. Calculate the margin of error (ME):
- ME = z * SEM = 2.576 * 1.31 = 3.374

5. Round the answer to three decimal places:
- ME = 3.374

Your answer: The margin of error for the 99% confidence interval for the population mean of grass seed germination periods is approximately 3.374 days.

The solution to the initial value problem would be:y(t) = y0e^(-kt), y(0) = y0.

The differential equation we're given to work with is y=−ky.

Here, k is a constant.

Therefore, the initial value problem would be:y=−ky,

y(0)=y0

We're given the differential equation y=−ky.

We can solve this using separation of variables.

We need to isolate the variable y and the derivative term on the opposite sides of the equation.

That means we need to divide both sides by `y` and multiply both sides by dt.

We get:dy/y=−kdt

Integrating both sides, we get:

ln|y|=−kt+C

where C is a constant.

Solving for y, we get:

y=Ce^(-kt)

Now we need to find the appropriate initial condition.

We're given that the initial value of y at time t = 0 is y0.

Therefore, the initial condition would be:

y(0) = y0

Substituting this value into our equation for y, we get:

y0 = Ce^(0)⇒ C = y0

Therefore, the solution to the initial value problem would be:y(t) = y0e^(-kt), y(0) = y0.
