the vertices of triangle wxy are located at w(-14,20). x(10,4) and y (-2,-4). what is the approximate length of the midsegment parallel to xy?

Answers

The approximate length of the midsegment parallel to xy is 6.63

The midsegment of a triangle is a line segment that connects the midpoints of two sides of the triangle and has the same length as each of the two sides.

To find the midpoint of a line segment, we average the x-coordinates and the y-coordinates of its endpoints.

Since the question stated that the midsegment is parallel to xy, we need to find midpoint of xw and yw.

First, let's find the midpoint of side xw:

Midpoint of xw : ((-14+10)/2, (20+4)/2) = (-2, 12)

Midpoint of yw : ((-14-2)/2, (20-4)/2) = (-8, 8 )

The length of a line segment between two points (x1, y1) and (x2, y2) in a two-dimensional coordinate system can be calculated using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Length line of midpoint xw and midpoint yw :

√((-2-(-8))^2 + (12-(8))^2) = √(6^2 + 4^2) = √(36 + 8) = √44

So, the length of the midsegment is parallel to XY, which is approximately equal to √44 = 6.63

Step-by-step explanation:

taco=3.50
burrito = 9.50
raised 1,020
Sold-120 items
How many tacos and burritos did they sell?

Answers

By using substitution method to solve the given equation they sold 20 tacos and 100 burritos .

Substitution method:

The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.

For example - x +y = 2 , x = 2-y

                       3x+3y = 6

            substituting value of x in equation 2 we get

                      y = 1

                       x = 1

According to the given information:

Let's assume x is the number of tacos sold and y is the number of burritos sold.

We know that:

The total amount raised from selling tacos and burritos is $1,020

The cost of one taco is $3.50

The cost of one burrito is $9.50

The total number of items sold is 120

Using this information, we can set up two equations:

3.50x + 9.50y = 1020 (total amount raised)

x + y = 120 (total number of items sold)

We can solve for x and y by using any method of solving systems of equations, such as substitution or elimination.

Let's use the substitution method:

x + y = 120 (equation 2)

y = 120 - x (solve for y)

3.50x + 9.50y = 1020 (equation 1)

3.50x + 9.50(120 - x) = 1020 (substitute y from equation 2)

3.50x + 1140 - 9.50x = 1020 (distribute)

-6x = -120 (subtract 1140 from both sides)

x = 20 (divide both sides by -6)

Now that we know x = 20, we can substitute it back into either equation to find y:

x + y = 120 (equation 2)

20 + y = 120 (substitute x = 20)

y = 100

Therefore, they sold 20 tacos and 100 burritos.

.Kwan is driving at a constant speed. After 141 hours he has driven a total distance of 90 miles. (a) How far will Kwan drive in 2 hours at this rate? (b) If D represents the distance Kwan has driven in miles and t represents the time he has been driving, in hours, then write an equation for D in terms of t. (c) Use your equation from (b) to determine how far Kwan drives in 15 minutes. (d) Kwan is driving a total of 234 miles. How long will his trip take him, to the nearest tenth of an hour, assuming he travels at this constant rate? Use proper units.

Answers

(a) Kwan will drive approximately 1.276 miles in 2 hours at his constant speed. (b) The equation representing the distance Kwan has driven (D) in terms of time (t) is D = 0.638t. (c) Kwan will drive approximately 0.1595 miles in 15 minutes, and (d) Kwan's trip of 234 miles will take approximately 366.8 hours at his constant rate.

(a) To determine how far Kwan will drive in 2 hours at the same constant speed, we can use the concept of proportionality. We can set up a ratio between the distance and time:

Distance / Time = Constant Speed

Let's calculate the constant speed first:

Constant Speed = Distance / Time

                 = 90 miles / 141 hours

                 ≈ 0.638 miles per hour

Now we can use the constant speed to find the distance Kwan will drive in 2 hours:

Distance = Constant Speed × Time

            = 0.638 miles per hour × 2 hours

            ≈ 1.276 miles

Therefore, Kwan will drive approximately 1.276 miles in 2 hours at this rate.

(b) The equation for D (distance) in terms of t (time) can be written as follows:

D = Constant Speed × t

Using the constant speed calculated earlier (0.638 miles per hour), the equation becomes:

D = 0.638t

(c) To determine how far Kwan drives in 15 minutes (0.25 hours), we can substitute t = 0.25 into the equation from part (b):

D = 0.638 × 0.25

    = 0.1595 miles

Therefore, Kwan will drive approximately 0.1595 miles in 15 minutes at this rate.

(d) If Kwan is driving a total of 234 miles, we can rearrange the equation from part (b) to solve for t:

D = 0.638t

234 = 0.638t

Dividing both sides of the equation by 0.638:

t = 234 / 0.638

   ≈ 366.77 hours

Kwan's trip will take approximately 366.8 hours.

1) Water is pumped from a lower reservoir to a higher reservoir by a pump that provides mechanical power to the water. The free surface of the upper reservoir is 45m higher than the surface of the lower reservoir. If the flow rate of water is measured to be 0.03m3/s and the diameter of the pipe is 0.025m determine the mechanical power of the pump in Watts. Assume a pipe friction factor of 0.007.

Answers

The mechanical power of the pump is 2,648,366.75 W (approx).

Given Data:

Flow rate of water = 0.03 m³/s

Diameter of the pipe = 0.025 m

Pipe friction factor = 0.007

Difference in height between two reservoirs = 45 m

We have to find the mechanical power of the pump in watts.

Power is defined as the amount of work done per unit time.

So, we can write the formula for power as:

P = W/t

Where,

P is the power in watts

W is the work done in joules and

t is the time taken in seconds.

The work done in pumping the water is given as:

W = mgh

where

m is the mass of the water,

g is the acceleration due to gravity and

h is the height difference between the two reservoirs.

To calculate the mass of water, we have to use the formula:

Density = mass/volume

The density of water is 1000 kg/m³.

Volume = Flow rate of water/ Cross-sectional area of the pipe

Volume = 0.03/π(0.025/2)²

Volume = 0.03/0.00004909

Volume = 610.9 m³/kg

The mass of water is given by:

M = Density x Volume

M = 1000 x 610.9

M = 610900 kg

So, the work done is given by:

W = mgh

W = 610900 x 9.8 x 45

W = 2,642,710 J

Let's calculate the power now:

V = Flow rate of water/ Cross-sectional area of the pipe

V = 0.03/π(0.025/2)²

V = 0.03/0.00004909

V = 610.9 m/s

Velocity head = V²/2g

Velocity head = 610.9²/2 x 9.8

Velocity head = 19051.26 m

Pipe friction loss = fLV²/2gd

where,

L is the length of the pipe

V is the velocity of water

d is the diameter of the pipe

f is the pipe friction factor

Given, L = 150m

Pipe friction loss = 0.007 x 150 x 610.9²/2 x 9.8 x 0.025⁴

Pipe friction loss = 5,656.75 m

Mechanical power = (W+pipe friction loss)/t Mechanical power

                               = (2,642,710 + 5,656.75)/1Mechanical power

                               = 2,648,366.75 W

Therefore, the mechanical power of the pump is 2,648,366.75 W (approx).

Hence, the required solution.

Two standard number cubes are rolled. What is the probability that the sum is greater than 9 or less than 6?

Answers

To find the probability that the sum of two standard number cubes is greater than 9 or less than 6, we need to consider the possible outcomes.


A standard number cube has 6 sides, numbered from 1 to 6. When two number cubes are rolled, there are 6 x 6 = 36 possible outcomes, as each cube has 6 possible outcomes.
To find the outcomes that satisfy the given condition, we can make a table to list all the possible sums:


Sum | Outcomes
2   | 1 + 1
3   | 1 + 2, 2 + 1
4   | 1 + 3, 2 + 2, 3 + 1
5   | 1 + 4, 2 + 3, 3 + 2, 4 + 1
6   | 1 + 5, 2 + 4, 3 + 3, 4 + 2, 5 + 1
7   | 1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, 6 + 1
8   | 2 + 6, 3 + 5, 4 + 4, 5 + 3, 6 + 2
9   | 3 + 6, 4 + 5, 5 + 4, 6 + 3
10  | 4 + 6, 5 + 5, 6 + 4
11  | 5 + 6, 6 + 5
12  | 6 + 6


From the table, we can see that there are 7 outcomes where the sum is greater than 9 or less than 6 (i.e., 10, 11, and 12).
The total number of possible outcomes is 36, so the probability of getting a sum greater than 9 or less than 6 is 7/36.
The probability that the sum is greater than 9 or less than 6 when two standard number cubes are rolled is 7/36.

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

the scores on a standardized test are normally distributed with a mmean of 90 and a standard deviation of 15. what is the percentage of scores that are greater than 69?

Answers

Approximately 91.92% of test-takers scored higher than 69 on this standardized test.

To find the percentage of scores that are greater than 69, we need to standardize the score by calculating its z-score:

z = (69 - 90) / 15 = -1.4

The z-score represents the number of standard deviations away from the mean a score is. Since the normal distribution is symmetric, we can find the percentage of scores greater than 69 by finding the area under the curve to the right of the z-score.

Using a standard normal distribution table or calculator, we find that the area to the right of a z-score of -1.4 is 0.9192.

random variables x and y have the joint cdf fx,y (x, y) = (1 − e−x )(1 − e−y ) x ≥ 0; y ≥ 0, 0 otherwise

Answers

The marginal CDF for y is Fᵧ(y) =\(y + e^{(-y) }- 1\), for y ≥ 0

How to find the marginal CDF?

The given joint cumulative distribution function (CDF) for random variables x and y is:

Fₓ,ᵧ(x, y) = \((1 - e^{(-x)})(1 - e^{(-y)})\), for x ≥ 0 and y ≥ 0

           = 0, otherwise.

From the joint CDF, we can determine the marginal CDFs for x and y by integrating the joint CDF with respect to the respective variable.

Marginal CDF for x:

Fₓ(x) = ∫[0,x] ∫[0,∞] fₓ,ᵧ(u, v) dv du

Since fₓ,ᵧ(u, v) is zero outside the domain x ≥ 0 and y ≥ 0, we can simplify the integration limits:

Fₓ(x) =\(\int _{[0,x]} \int _{[0,\infty]}\) \((1 - e^{(-u)})(1 - e^{(-v)})\) dv du

      = ∫\([0,x] [1 - e^{(-u)}]\) du

      = \([u + e^(-u)]\)|[0,x]

      = \(x + e^{(-x)} - 1\), for x ≥ 0

Therefore, the marginal CDF for x is given by:

\(Fₓ(x) = x + e{(-x)} - 1\), for x ≥ 0

Marginal CDF for y:

Fᵧ(y) = ∫[0,∞] ∫[0,y] fₓ,ᵧ(u, v) du dv

Using similar reasoning as above, we can simplify the integration limits:

Fᵧ(y) = \(\int _{[0,\infty]} \int_{[0,y]}\)(1 - \(e^{(-u)}\))(1 - \(e^{(-v)}\)) du dv

      = \(\int_{[0,y]}\) [1 -\(e^{(-v)}\)] dv

      = [v +\(e^{(-v)}\)]|[0,y]

      = y + \(e^(-y)\) - 1, for y ≥ 0

Therefore, the marginal CDF for y is given by:

Fᵧ(y) =\(y + e^{(-y)} - 1\), for y ≥ 0

These are the marginal CDFs for the random variables x and y based on the given joint CDF.

Consider the Solow growth model with neither technological nor population change. The parameters of the model are given by s=0.3 (savings rate) and

δ=0.08(depreciation rate).

Let k denote capital per worker; y output per worker;

Solve for output per worker (y*) in the steady state. Show your derivations.

Answers

The steady-state output per worker (y*) is given by y* = A*(k*)^(1/3), and the level of technology (A) remains constant in the steady state.

To derive the steady-state output per worker (y*) in the Solow growth model, we start with the production function:

y = Ak^(1/3)

Where y represents output per worker, A is the level of technology, and k is capital per worker. In the steady state, capital per worker remains constant, so we have dk/dt = 0, where d represents the derivative.

Taking the derivative of the production function with respect to time (t), we get:

dy/dt = (dA/dt)k^(1/3) + A(1/3)k^(-2/3)dk/dt

Since dk/dt = 0 in the steady state, the equation simplifies to:

dy/dt = (dA/dt)k^(1/3)

In the steady state, output per worker does not change over time, so dy/dt = 0. This leads to:

(dA/dt)k^(1/3) = 0

Since k^(1/3) is positive, we must have dA/dt = 0. This means that the level of technology (A) remains constant in the steady state.

Now, substituting A = A* (where A* represents the steady-state level of technology) into the production function, we have:

y* = A*(k*)^(1/3)

where k* represents the steady-state capital per worker.

Therefore, the steady-state output per worker (y*) is given by y* = A*(k*)^(1/3), and the level of technology (A) remains constant in the steady state.

1. Start with the function f(x) = sin√(2x+3).

2. Apply the chain rule: d/dx(sin(u)) = cos(u) * du/dx, where u = √(2x+3).

3. Differentiate the inside function u = √(2x+3) with respect to x. We get du/dx = 1 / (2√(2x+3)).

4. Multiply the derivative of the inside function (du/dx) with the derivative of the outside function (cos(u)).

5. Substitute the values back: f'(x) = (cos√(2x+3)) / (2√(2x+3)).

what is the smallest possible perimeter, in units, of a triangle whose side-length measures are consecutive integer values?

Answers

If a triangle whose sides length measures are consecutive integers, then the smallest possible perimeter is 9 units

If a, b and c are the sides of the triangle

Then it will be

a + b > c

b + c > a

c + a > b

Given that the side length of the measures are consecutive integer

Smallest consecutive integer is 1, 2 and 3

But

1 +2 > 3

3 = 3

Therefore it will not be the sides of the triangle

Next smallest consecutive integers are 2, 3 and 4

Then,

2+3 > 4

5 > 4

3+4 > 2

7 > 2

2+4 > 3

6 > 3

This will be the sides of the triangle

The perimeter of the triangle is the sum of sides of the triangle

The perimeter = 2 + 3 + 4

= 9 units

Hence, if a triangle whose sides length measures are consecutive integers, then the smallest possible perimeter is 9 units

if r(t) = (4t, 3tยฒ, 4tยณ) , find r'(t), T(1), r''(t), and r'(t) ร r ''(t).

Answers

The value of the expression is r'(t) = (4, 6t, 12t²), T(1) = (2/7, 3/7, 6/7), r''(t) = (0, 6, 24t), r'(t) ร r''(t) = 144t³.

We are given the vector-valued function r(t) = (4t, 3t², 4t³).

To find r'(t), we need to take the derivative of each component of r(t) with respect to t:

r'(t) = (d/dt)(4t), (d/dt)(3t²), (d/dt)(4t³)

r'(t) = (4, 6t, 12t²)

To find T(1), we need to evaluate r'(t) at t = 1 and then divide by the magnitude of r'(1):

r'(1) = (4, 6(1), 12(1)²) = (4, 6, 12)

| r'(1) | = sqrt(4² + 6² + 12²) = sqrt(196) = 14

T(1) = r'(1) / | r'(1) | = (4/14, 6/14, 12/14) = (2/7, 3/7, 6/7)

To find r''(t), we need to take the derivative of each component of r'(t) with respect to t:

r''(t) = (d/dt)(4), (d/dt)(6t), (d/dt)(12t²)

r''(t) = (0, 6, 24t)

Finally, to find r'(t) ร r''(t), we need to take the dot product of r'(t) and r''(t):

r'(t) ร r''(t) = (4, 6t, 12t²) ร (0, 6, 24t)

r'(t) ร r''(t) = 0 + 6t(6t) + 12t²(24t)

r'(t) ร r''(t) = 144t³

Therefore, we have:

r'(t) = (4, 6t, 12t²)

T(1) = (2/7, 3/7, 6/7)

r''(t) = (0, 6, 24t)

r'(t) ร r''(t) = 144t³
