find all values of x such that (3, x, −5) and (2, x, x) are orthogonal. (enter your answers as a comma-separated list.)

Answers

Answer 1

Two vectors are orthogonal if their dot product is zero. So, we need to find the dot product of (3, x, -5) and (2, x, x) and set it equal to zero:

(3, x, -5) ⋅ (2, x, x) = (3)(2) + (x)(x) + (-5)(x) = 6 + x^2 - 5x

Setting 6 + x^2 - 5x = 0 and solving for x gives:

x^2 - 5x + 6 = 0

Factoring the quadratic equation, we get:

(x - 2)(x - 3) = 0

So, the solutions are x = 2 and x = 3.

Therefore, the values of x such that (3, x, −5) and (2, x, x) are orthogonal are x = 2 and x = 3.

Note that the above problems are solved using the knowledge of the sum of angles in a triangle.

10) when computed, x = 13°
11) when computed m∠S = 158°

12) when computed, ∠P = 115.625°; ∠Q = 21.125°; ∠R = 43.25°

13) when computed, angles L, J, K is 52°, 45°, 83° respectively.
14) When computed,

∠b = 108°

∠c = 36°

∠d = 36°

What is the sum of angles in a Triangle?

Note that the Triangles Theorem posits that the sum of Angles in a Triangle = 180°

10) To solve for x, we know that:

the triangle is an Equilateralall the angles are equalAll the angles sum up to 180°one of the angles is given as 8x-44°

Given the above, we can state:

8x-44 = 180/3
8x-44 = 60

8x = 60 +44

x = 104/8

x = 13°

Thus x = 13°

11) For this problem, the key to solving for x is to note that the triangle is isosceles.

This means that,

15x - 31 = 9x + 11

Thus, collecting like terms, we have:

15x-9x = 11+ 31

24x = 42

x = 42/24

Thus,

x = 1.75

Since we are looking for m∠S, we can arrive at this by removing (15x - 31 ) + (9x + 11) from 180° based on the rule of the Sum of Angles in a triangle.
That is:

180 -  (15x - 31 ) + (9x + 11) = m∠S


To do this, we must impute the value of x in to the above equation:
⇒ m∠S = 180 -  ((15 * 1.75) - 31 ) + ((9 * 1.75) + 11)
⇒ m∠S = 180 -  (-4.75) + 26.75
m∠S = 180 -  22; thus

m∠S = 158°

12) <M, <P, <R, recall that the sum of the interior angles of triangle MPR will add up to 180 degrees

so <M + <P + <R = 180

We have ∠P is 14 less than five times x = 5x-15

∠Q is five less than x = x - 5

∠R is nine less than twice x =2x - 9

Recall the angle sum property of the triangle: The sum of all angles of a triangle is 180°

So, 5x -15 + x - 5 + 2x - 9 = 180°

Collect like terms to get

8x - 29 = 180

8x = 180+29

Thus,

x= 26.125

So,∠P  = 5x-15

=5 (26.125) -15

∠P = 115.625°

∠Q =x-5

=26.125 - 5

∠ Q =21.125°

∠R = 2x - 9

=2(26.125)-9

Thus

∠R = 43.25°

To confirm, if the above ∠ sum up to 180°, we say

Check 43.25+21.125+115.625

⇒ 43.25+21.125+115.625 = 180° is TRUE.

13) To solve for ∠J, ∠K  and ∠ L, recall that

The sum of the interior angles of triangle JKL will add up to 180 degrees

so <J + <K + <L = 180

L = measure of angle L

J = measure of angle J = L - 7

K = measure of angle K = 2L - 21

Thus, L + L-7 + 2L - 21 = 180; Collect like terms and we have

4L - 28 = 180

4L = 208

L = 52°,

If L is 52 then

J = L - 7 = 52 - 7

= 45°

K = 2L - 21 = 2(52) - 21

= 83

To check that they all sum up to 180° we say:

52+ 45+83

= 180°


14)

The sum of angle in a triangle is 180 degrees

Hence <b + <c + <d = 180

13x-35 + 5x - 19 + 2x + 14 = 180

13x+5x+2x-35-19+14 = 180

20x-40 = 180

20x = 180 + 40

20 x = 220

x = 220/20

x = 11

Get <b

<b = 13x-35

<b = 13(11) - 35

<b = 143-35

<b = 108 degrees

Get <c

c =5x-19

<c = 5(11)-19

<c = 55-19

<c = 36degrees

<d = 2x+14

What is empirical rule?

The empirical rule, also known as the three-sigma rule or the 68-95-99.7 rule, is a statistical rule stating that for a normal distribution, nearly all observed data will fall within three standard deviations (denoted by σ) of the mean or average (denoted by µ).

The Empirical Rule states that 99.7% of data from a normal distribution is within 3 standard deviations of the mean.

68% of the data is within one standard deviation of the mean, 95% is within two standard deviations, and 99.7% is within three standard deviations, according to this rule.

What is m/M?

Answers

Answer:  ∠M = 98°

Step-by-step explanation:

Given:

∠M = (3x-16)°

∠N = x°

∠O = (x+6)°

Sum of all angles in a triangle is 180°

Therefore, 180° = ∠M +∠N +∠O, substitute the given values

180° = (3x-16)° + x° + (x+6)° (add/combine like terms)

180° = (3x+x+x)° + (-16+6)°

180° = (5x)° + (-10°)

180° + 10° = (5x)° ( divide both sides by 5)

190°/5 = (5x)°/5

38° = x°

IF ∠M = (3x-16)°, substitute x°=38°,

Therefore, ∠M = 3(38)-16

                   ∠M = 114 - 16 = 98°

By calculating the price change percentage for each decade, you can calculate the overall rate of change between 1960 and 2000.

A quick calculation shows how much gasoline prices are expected to climb over the next ten years. Subtract the original price from the new price to determine the percent change, then divide the result by the original price and multiply by 100. We must now calculate the percentage change when 25 is raised to 45. To determine the percentage change, we can easily use the formula.

An Isosceles triangle has two congruent sides. the first side is expressed by x+2 and the second side is expressed by 2x-25 what is the value of X

Answers

The value of x is 27

How to determine the value

From the information given, we have that the triangle is an isosceles triangle.

The properties of an isosceles triangle are;

It has two equal sidesTwo equal anglesIt has three edges and three verticesSum of internal angles is 180

We have that;

First side = x + 2

Second side = 2x - 25

Equate the two sides, we get;

x+ 2 = 2x - 25

collect like terms

x - 2x = - 25 - 2

subtract like terms

-x= -27

make 'x' the subject

x = 27

Hence, the value is 27

You deposit $1000 in a savings account that earns 5% annual interest compounded yearly.
a. Write an exponential equation to determine when the balance of the account will be $1500
b. Solve the equation.

Answers

Answer:

a. 1500 = 1000 × 1.05^x

b. 1500 = 1000 × 1.05^x

Divide both sides by 1000

1500/1000 = 1.05^x

Take the natural log of both sides

ln(1500/1000) = ln(1.05^x)

ln(1.5) = x ln(1.05)

x = ln(1.5) / ln(1.05)

x = 5.12 years

Bus 1 leaves Bulawayo at a constant speed of 80mph headed for Harare, 550 miles away. Bus 2 leaves Harare at 8:30AM traveling at 50mph. At what time will the buses pass each other?

Answers

The buses will pass each other at 12:37:30 PM

Calculation of time two buses pass each other.Bus 1 leaves Bulawayo at a constant speed of 80 mph headed for Harare, 550 miles away, Bus 2 leaves Harare at 8:30 AM traveling at 50 mph.

To find the time when the two buses will meet, you need to find the time that Bus 2 will take to travel to the point where the buses will meet, and the time that Bus 1 will take to travel the same distance.

You can find the time that Bus 2 will take to travel to the point where the buses will meet by dividing the distance (550 miles) by the speed of Bus 2 (50 mph), which is 11 hours.

Then you can find the time that Bus 1 will take to travel the same distance by dividing the distance (550 miles) by the speed of Bus 1 (80 mph), which is 6.875 hours (or 6 hours and 52.5 minutes).

Now, you can subtract the time that Bus 2 takes to reach the point of intersection from the time that Bus 1 takes to reach the same point.

6.875 hours (or 6 hours and 52.5 minutes) - 11 hours = -4.125 hours (or -4 hours and 7.5 minutes)

Since Bus 2 leaves Harare at 8:30AM, you can subtract -4.125 hours from 8:30AM to find the time the buses will meet.

8:30AM - -4.125 hours = 12:37:30 PM

So the buses will pass each other at 12:37:30 PM

Richard Rambo presently owns the Marine Tower office building, which is 20 years old, and is considering renovating it. He purchased the property two years ago for $800,000 and financed it with a 20-year, 75 percent loan at 4.5 percent interest (monthly payments). Of the $800,000, the appraiser indicated that the land was worth $200,000 and the building $600,000. Rambo has been using straight-line depreciation over 39 years (1/39 per year for simplicity). At the present time Marine Tower is producing $52,000 in NOI, and the NOI and property value are expected to increase 2 percent per year. The current market value of the property is $820,000. Rambo estimates that if the Marine Tower office building is renovated at a cost of $200,000, NOI will be about 20 percent higher next year ($62,400 vs. $52,000) due to higher rents and lower expenses. He also expects that with the renovation the NOI will increase 3 percent per year instead of 2 percent. Furthermore, Rambo believes that after five years, a new investor will purchase the Marine Tower office building at a price based on capitalizing the projected NOI six years from now at a 6 percent capitalization rate. Selling costs would be 6 percent of the sale price. Rambo is currently having to pay 35 percent tax on ordinary income, 20 percent on capital gain, and 25 percent on depreciation recapture which he expects to remain the same in the future. He also would not be subject to any passive activity loss limitations. If Rambo does the renovation, he believes that he could obtain a new loan at a 5 percent interest rate and a 20-year loan term (monthly payments).Required: a. Assume that if Rambo does the renovation, he will be able to obtain a new loan that is equal to the balance of the existing loan plus 75 percent of the renovation costs.

Once a customer arrives, an order will be placed immediately and the cooks of the restaurant will process orders in a first come first serve pattern. After an order is finished by a cook, the customer will pick up the food and leave immediately. During the time the food is prepared, a customer waits in the restaurant. For simplicity, we assume this restaurant opens 24 hours every day and customers arrive to the restaurant according to a Poisson process with constant rate 20 per hour. The cooking time for each order is exponentially distributed with rate 10 per hour. Each cook in the restaurant can only process one order at one time. Each cook works independently. The time it takes to place an order is considered to be negligible (e.g., through mobile apps or kiosks) and is not counted in the model. Consider a continuous time stochastic process {X(t):t> 0} where X(t) is the number of customers in the restaurant at time t. a.) Suppose that there is only one cook in the restaurant.
