if you see this i really need help asap! ty, 'A man pushes a 10 kg box with a force of 5 N. How much will the box accelerate?'

Answer:

Below

Step-by-step explanation:

The plane's distance is the hypotenuse of a right triangle with legs of

(50 -20)mi = 30 miles     and     30500 - 18000 = 12500 ft

                             for consistent units  12500ft/5280ft/mile = 2.36742 miles

Now just use Pythagorean theorem

Hypotenuse^2 = leg1^2 + leg2^2

               h^2    = 30^2 + 2.36742^2

                   h = ~ miles 30.093 miles  ( note that the vertical descent distance does not matter much)

    (this is 158 892 feet)

Answer: \(\frac{\pi }{2 }\) < ∅ < \(\frac{3}{4}\pi\)  

Step-by-step explanation:

They are asking where is cos∅ negative.  cos is your x value in the unit circle (your adjacent)

So cos∅ is neg between \(\frac{\pi }{2 }\) < ∅ < \(\frac{3}{4}\pi\)    

theta is <  but not = those values because cos ∅ is 0 (which is neither neg or pos.              

Answer: \(\frac{\pi }{2 }\) < ∅ < \(\frac{3}{4}\pi\)      

The probability density function for U is  {2/(1+U)³; U≥0

           0, U<0}

What is the probability?

A probability is a number that reflects how likely an event is to occur. It is expressed as a number between 0 and 1, or as a percentage between 0% and 100% in percentage notation. The higher the likelihood, the more probable the event will occur.

Here, we have

Given: The joint distribution for the length of life of two different types of components operating in a system is given by

f(y₁, y₂) = { 1/27 y₁\(e^{-(y_1+y_2)/3}\), y₁ > 0, y₂ > 0

                  0,     elsewhere, }

Let U = y₂/y₁ and Z = y₁ and y₂ = UZ

|J| = \(\left|\begin{array}{cc}1&0\\U&Z\end{array}\right|\) = Z

The joint distribution of U and Z is

f(U,Z) = 1/27 Z²\(e^{-(Z+UZ)/3}\), Z≥0, U≥0

The marginal distribution is:

f(U) = \(\frac{1}{27} \int\limits^i_0 {Z^2e^{-(Z+UZ)/3} } \, dZ\)

f(U) = 2/(1+U)³; U≥0

f(U) = {2/(1+U)³; U≥0

           0, U<0}

Hence,  the probability density function for U is  {2/(1+U)³; U≥0

           0, U<0}

The correctanswer is-the percentage of the pieces that will meet the length specs is 98.78%.

The given data may be a random variable that takes after the normal distribution with mean μ=64 and standard deviation σ=0.1

The required value is to discover the rate of the pieces that will meet the length specs which is between 63.76 and 64.24 inches.

To find the required percentage, standardize the given limits as follows: Lower Limit: (63.76 - μ) / σ= (63.76 - 64) / 0.1 = -2.4

Upper Limit: (64.24 - μ) / σ= (64.24 - 64) / 0.1 = 2.4

Using the Standard Normal Distribution Table, the probability that the value will fall between -2.4 and 2.4 is found to be 0.9878.

The required percentage is then found by multiplying the probability by 100, which is: Percentage = 0.9878 x 100% = 98.78%

Therefore, the percentage of the pieces that will meet the length specs is 98.78%.

The root of the graph of f(x) =(x - 5)3(x + 2)2 touches the x-axis at -2,5

(x - 5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)^2 has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

Given: Function f(x) is (x - 5)3(x + 2)2

If a curve touches the x-axis then f(x) = 0

⇒ (x - 5)3(x + 2)2 = 0.

But if ab = 0 ⇒ either a = 0 or b = 0 or both zero.

⇒ (x - 5)3 = 0 and (x + 2)2 = 0

⇒ (x - 5) = 0 and x + 2 = 0

⇒ x = 5 and x = - 2.

To prove that in a group of 250 students, the family name of at least ten students must start with the same letter, we can use the Pigeonhole Principle.

The Pigeonhole Principle states that if you have n pigeonholes (in this case, the 26 letters of the English alphabet) and you are placing m > n items (here, 250 students) into the pigeonholes, at least one pigeonhole must contain more than one item.

Here's a step-by-step explanation:

1. We have 26 pigeonholes, representing the 26 letters of the English alphabet.

2. We have 250 students (items) to place into these pigeonholes based on the first letter of their family name.

3. Apply the Pigeonhole Principle: Divide the total number of students (250) by the total number of pigeonholes (26).

  250 ÷ 26 ≈ 9.6

4. Since we can't have a fraction of a student, we round up to the nearest whole number.

  10 students per pigeonhole

5. By rounding up, we find that at least one pigeonhole (letter of the alphabet) must have 10 or more students with family names starting with that letter.

So, in a group of 250 students, the family name of at least ten students must start with the same letter, as demonstrated by the Pigeonhole Principle.

The perimeter of square WXYZ can be determined by considering the properties of the inscribed circle. The perimeter of square WXYZ is approximately 33.94 inches

In a square, the diagonals bisect each other at right angles and intersect at the center of the square. The radius of the inscribed circle is the distance from the center to any side of the square. Since the radius is given as 6 inches, it is also the distance from the center to any corner of the square.

The radius of the inscribed circle forms a right triangle with half of one side of the square and the diagonal. The length of half a side of the square is equal to the radius of the inscribed circle, which is 6 inches. The diagonal of the square is twice the length of one side, so it is 12 inches.

Using the Pythagorean theorem, we can calculate the length of one side of the square:

(side length)^2 + (side length)^2 = (diagonal length)^2

(6 inches)^2 + (6 inches)^2 = (side length)^2

36 inches^2 + 36 inches^2 = (side length)^2

72 inches^2 = (side length)^2

Taking the square root of both sides, we get:

side length = √72 inches ≈ 8.485 inches

Since the square has four equal sides, the perimeter of the square is:

perimeter = 4 * side length = 4 * 8.485 inches = 33.94 inches

Therefore, the perimeter of square WXYZ is approximately 33.94 inches.

the measure of angle ∠B is 38/5 and the measure of angle ∠Q

is 18/5.

We are given that δABC ≅ δPQR. This means that the corresponding angles in the two triangles are congruent. Specifically, angle ∠B in δABC is congruent to angle ∠Q in δPQR.

Let's equate the expressions for the angle measures:

3v + 4 = 8v - 6

Simplifying the equation, we have:  6 = 5v

Dividing both sides by 5, we find:  v = 6/5

Now, we can substitute this value of v back into the expressions for the angle measures:

m∠B = 3v + 4

= 3(6/5) + 4

= 18/5 + 4

= 38/5

m∠Q = 8v - 6

= 8(6/5) - 6

= 48/5 - 6

= 48/5 - 30/5

= 18/5

Step-by-step explanation:

Doug made sales worth A. $3,200 in the last week.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Doug is a salesperson in a retail store and earns $75 per week,

Plus 15% of his weekly sales.

Doug makes $555 one week,

∴ He made $(555 - 75) = $480.

So, $480 is 15% of his weekly sales, Assuming he made sales worth $x.

∴ 15% of x is $480.

(15/100)×x = 480.

0.15x = 480.

x = 480/0.15.

x = 3200.

The exact value of the trigonometric expression \(\frac{tan-(2\pi/3) }{sin(7\pi /4)} - sec(-\pi )\) in the simplified radical form is √6  +  1.

\(\frac{tan-(2\pi/3) }{sin(7\pi /4)} - sec(-\pi )\)

We have the angle,

-2π/3  =  -120° = (360 - 120)°  = 240° = 60°

Put the value of -2π/3 in tan -2π/3, we get

tan -2π/3 =  tan (60)  = √3

7π/4 × 180/π  =  7 × (180/4)  =  7 × 45  =  315° =  45°

Put the value of 7π/4 in sin 7π/4, and we get

sin 7π/4 = sin (45°) = √2/2

sec (-π)  =  sec (π)  = -1

Now, substitute all the values in the given equation,

= {√3/(√2/2)} - (-1)

= (2√3/√2) + 1

= (2√3 × √2/√2 × √2) +1

= (2√6/2) + 1

Answer:

the length and width be 13.33 feet and 34.67 feet respectively

Step-by-step explanation:

The computation is shown below:

Let us assume the width be x

So, the length be 2x + 8

As we know that

The perimeter of the rectangle = 2(length + width)

96 = 2(2x + 8 + x)

96 = 4x + 16 + 2x

96 - 16 = 6x

80 = 6x

x = 80 ÷ 6

= 13.33 feet

So, the length would be

= 2 × 13.33 + 8

= 34.67 feet

Hence, the length and width be 13.33 feet and 34.67 feet respectively

The antiderivative of f(x) = tan⁻¹(x) is x tan⁻¹(x) − ln(x²+1)/2 + C

The term antiderivative in math is referred as a function that reverses what the derivative does

Here we have given the expression f(x) = tan⁻¹(x).

Now, the antiderivative of the expression is calculated by doing the integral

=> ∫tan⁻¹(x)dx

By using the integration by parts ∫udv = uv−∫vdu

Here let us consider that u=tan⁻¹(x) and dv=dx

And the value of du is calculated as,

=> du =  ∫tan⁻¹(x)dx =  dx/(x² + 1)

And the value of v = x.

Then the expression is written as,

=>  ∫tan⁻¹(x)dx = x tan⁻¹(x) - ∫x/(x² + 1)dx

As per the concept of the constant of integration, it can be simplified as,

=> x tan⁻¹(x) − ln(x²+1)/2 + C
