Solve the following equation for θ on the interval [0,2π).
2sec(θ)+3=0
Round your answers to the nearest thousandth of a radian.
there should be 2 answers

Answers

Answer 1

We can start by isolating the secant term and then taking the inverse cosine of both sides. Remember that the inverse cosine function only gives results on the interval [0,π], so we will need to adjust our solutions accordingly:

2sec(θ) + 3 = 0

2sec(θ) = -3

sec(θ) = -3/2

cos(θ) = -2/3

θ = ±cos⁻¹(-2/3)

Using a calculator, we find:

θ ≈ 2.302, 4.981 radians

What is the value of 0 in the equation?

However, we need to adjust these solutions to be within the interval [0,2π). Since cos(x) = cos(2π - x), we can add to the negative solution to get an equivalent positive solution:

θ ≈ 2.302, 7.438 radians

Rounding to the nearest thousandth, we get:

θ ≈ 2.302, 7.438 radians

A Norman window is constructed by adjoining a semicircle to the top of an ordinary rectangular window. Find the dimensions of a Norman window of maximum area when the total perimeter is 20 feet.

Answers

As a result, when the entire circumference is 20 feet, the Norman window's maximum area measurements are as follows: x = 8 feet, or around 2.546 feet, is the width, Height: 9.087 feet, or about y = 16 - 16/feet.

Define Perimeter.

Perimeter is the total distance around the boundary of a two-dimensional shape, such as a polygon, a circle, or a rectangle. It is the sum of the lengths of all sides or edges of the shape.

Define Area.

Area is a measure of the size or extent of a two-dimensional surface or region. It is the amount of space enclosed within a closed shape or boundary.

Let's assume that the width of the rectangular part of the window is x and the height is y.

The perimeter of the window is given by:

Perimeter = width + height + semicircle circumference

Perimeter = x + y + πx/2

We are given that the total perimeter is 20 feet, so we can write:

x + y + πx/2 = 20

We can solve for y in terms of x:

y = 20 - x - πx/2

The area of the window is given by:

Area = rectangular part area + semicircle area

Area = xy + πx^2/8

We can substitute the expression we obtained for y into the equation for the area:

Area = x(20 - x - πx/2) + πx^2/8

Simplifying this expression, we get:

Area = 20x - (π/2)x^2 + πx^2/8

Area = 20x - (π/2)x^2/4

To find the maximum area, we can take the derivative of the area function with respect to x and set it equal to zero:

d/dx (Area) = 20 - (π/2)x/2 = 0

Solving for x, we get:

x = 8/π

Substituting this value back into the expression for y that we obtained earlier, we get:

y = 20 - 8/π - π(8/π)/2 = 20 - 4π/π - 16/π = 20 - 4 - 16/π = 16 - 16/π

Therefore, the dimensions of the Norman window of maximum area when the total perimeter is 20 feet are:

Width: x = 8/π feet (approximately 2.546 feet)

Height: y = 16 - 16/π feet (approximately 9.087 feet)

If two  lines intersect  at an angle of 90˚ or are perpendicular to each other, they form a right angle. A right angle is indicated by the symbol ∟Angle is always 90° or a right angle. The  opposite angle of 90° is the hypotenuse. The hypotenuse is always the longest side. The sum of the remaining two interior angles is  90°.  In a right-angled triangle, the side opposite  the 90-degree angle is called the hypotenuse, indicated by the letter "c". The sides adjacent to a 37 degree angle and a right angle are called "ab" and "bc" respectively.  

Using trigonometry, we  find the length of "ab" as follows:

Give your answer to two decimal places.​

Answers

Therefore, a sharpening costs Dollar 1.85.

what is dollar

The US, Canada, Australia, and some nations in the Pacific, Caribbean, Southeast Asia, Africa, and South America all use the dollar as their primary unit of exchange. The word "$" is used to denote it.

Let's use $a for the sharpener's price. We can state that the price of a book is $a + 1.95 because it costs $1.95 more than a sharpening.

We are aware of the $26.10 total cost of 10 sharpeners and 2 books. This can be expressed as an equation:

10a + 2(a + 1.95) = 26.10

If we simplify this equation, we get:

12a + 3.90 = 26.10

3.90 less from each side results in:

12a = 22.20

By multiplying both sides by 12, you get:

The distance between Point A and Point B along a jogging track is 24 Km. Gerald
starts from Point A and jogs at a speed of 6 Km/h. Shaun starts from Point B 30 min
after Gerald but reaches Point A 30 min earlier. What is Shaun's average speed?

Answers

Answer: Let's start by finding out the time it takes for Gerald to jog from Point A to Point B. We can use the formula:

distance = rate x time

to do this. Since the distance between Point A and Point B is 24 km and Gerald's speed is 6 km/h, we have:

24 = 6t

where "t" is the time it takes for Gerald to jog from Point A to Point B. Solving for "t", we get:

t = 4

So Gerald takes 4 hours to jog from Point A to Point B.

Now, let's look at Shaun's journey. We know that he starts 30 minutes after Gerald and reaches Point A 30 minutes earlier than Gerald. This means that the time it takes for Shaun to travel from Point B to Point A is 3.5 hours (i.e., 4 hours - 0.5 hours + 0.5 hours).

Using the formula distance = rate x time again, we can find out Shaun's average speed:

24 = rate x 3.5

simplifying, we get:

rate = 6.857 km/h

So Shaun's average speed is 6.857 km/h (or approximately 6.86 km/h rounded to two decimal places).

Answer:

  8 km/h

Step-by-step explanation:

You want to know Shaun's average speed on a 24 km jogging track if Gerald jogged at 6 km/h for the distance, while Shaun left half and hour later and arrived half an hour earlier than Gerald.

Gerald's time

The time it took Gerald to complete the distance is found from ...

  time = distance/speed

  time = (24 km)/(6 km/h) = (24/6) h = 4 h

Shaun's time

Shaun left half an hour later than Gerald, and completed the trip half an hour before Gerald did. Shaun's time was 1 hour less than Gerald's, so was ...

  4 h -1 h = 3 h

Shaun's speed

Shaun's average speed can be found from ...

  speed = distance/time

  speed = (24 km)/(3 h) = 8 km/h

Shaun's average speed was 8 km/h.

Since the zeros of the function are at x = -5, -1, and 4, the factors of the equation will be:

(x + 5), (x + 1), and (x - 4)

Multiplying these factors together gives us:

f(x) = a(x + 5)(x + 1)(x - 4)

To find the value of the constant term a, we can use the fact that the graph passes through the point (0, -4):

-4 = a(0 + 5)(0 + 1)(0 - 4)

-4 = -20a

So, we have

a = 1/5

Therefore, the function equation is:

Anthony has decided to purchase a $19,000 car. He plans to put 20% down toward the purchase and to finance the rest at a 6.8% interest rate for 4 years. Find his monthly payment.
Find the total price Anthony paid for his vehicle.

Answers

The monthly payment and total price paid by Antony at interest rate of 6.8% for vehicle is $362.59 and $21204.4 respectively.

Cost price of the car Antony decided to purchase = $19,000

Down payment =  20% of purchase value

Interest rate of amount to be finance = 6.8%

Time period of finance amount = 4 years

Down payment = 0.2 × $19,000

                         = $3,800

Amount that Anthony needs to finance,

Amount to finance = $19,000 - $3,800

                               = $15,200

The monthly payment , use the formula for the monthly payment on a loan,

M = P × r × (1 + r)ⁿ / ((1 + r)ⁿ - 1)

where M is the monthly payment,

P is the principal the amount to finance

r is the monthly interest rate

n is the total number of payments which is the number of years multiplied by 12

The monthly interest rate is 6.8% / 12 = 0.00567,

and the total number of payments is 4 × 12 = 48.

Substituting these values into the formula, we get,

⇒M = $15,200 × 0.00567 × (1 + 0.00567)⁴⁸ / ((1 + 0.00567)⁴⁸ - 1)

⇒M = $15,200 × 0.00567 × 1.3118 / (1.3118 -1)

⇒M = $15,200 × 0.00567 × 1.3118 / 0.3118

⇒M = 113.056 / 0.3118

⇒M ≈ $362.59

Anthony's monthly payment will be about $362.59

Total price that Anthony paid for his vehicle,

add up the down payment and the total amount of payments over the 4-year period.

Total price = $3,800 + ( $362.59 × 48)

                  = $21204.4

Therefore, the monthly payment and the total price at interest rate of 6.8% that Anthony paid for vehicle is $362.59 and $21204.4 respectively.

To find the positive zero of the given polynomial function f(x), we can use a numerical method such as the Newton-Raphson method or the bisection method. However, since an exact method is not specified in the question, we can use a graphing calculator or software to approximate the zero.

Using a graphing calculator or software, we can plot the graph of the function f(x) and find the x-value where the graph intersects the x-axis (i.e., where f(x) = 0) and is positive. This x-value will be the approximate positive zero of the function f(x).

For the function f(x) = 2x² - 1, the positive zero can be found by setting f(x) = 0 and solving for x:

2x² - 1 = 0
2x² = 1
x² = 1/2
x = ±√(1/2)

Since we are looking for the positive zero, we take x = √(1/2) ≈ 0.71 (rounded to two decimal places).

For the function f(x) = -16x³ - 3x² - 8x - 2, we can also use a graphing calculator or software to find the positive zero. When we plot the graph of this function, we can see that the positive zero is between x = 0 and x = 1. We can then use a numerical method or trial-and-error to approximate the zero more accurately. One possible approximation is x ≈ 0.17 (rounded to two decimal places).

Answers

The likelihood that the average tariff rate of 400 shipments of ethanol picked at random will be inside $80 of the average tariff rate of all shipments is roughly 0.789, or 78.9%.

What is probability?

The probability that an event will occur or that a proposition is true is quantified by probability theory, a branch of mathematics. A number from zero to one, where 0 approximately indicates how likely the event will happen and 1 generally indicates certainty, is the probability given an occurrence. In mathematics, probability is a measure of how likely an event is to take place. Probability levels can also be expressed as percent between 0 and 100 percent in addition to the numerals 0 to 1. the percentage of all outcomes out of all equally likely alternatives that lead to a specific occurrence, represented as a ratio.

given,

To solve this problem, we need to use the central limit theorem, which states that the distribution of sample means is approximately normal, with mean equal to the population mean and a standard deviation determined by dividing the population's standard deviation by the sample size square root.

We are given that the standard deviation of the population of tariff rates is $1200. Let mu be the population mean tariff rate, and x-bar be the sample mean tariff rate. We want to find the probability that the sample mean is within $80 of the population mean, i.e., |x-bar - mu| <= $80.

Using the formula for the standard error of the mean, we have:

SE = sigma/sqrt(n) = $1200/sqrt(400) = $60

Now, we can standardize the variable z = (x-bar - mu)/SE, and find the probability of |z| <= 80/60 = 4/3 using a standard normal distribution table or calculator.

P(|z| <= 4/3) = 0.7887

Therefore, the probability that the mean tariff rate of 400 randomly selected railroad-car shipments of ethanol will be within $80 of the mean tariff rate of all railroad-car shipments of ethanol is approximately 0.789 or 78.9% (rounded to three decimal places).

Interpretation: Sampling error refers to the natural variation in sample statistics (such as the sample mean) that occurs due to chance, even when the sample is randomly selected and representative of the population. In this case, the probability of the sample mean tariff rate being within $80 of the population mean is high (78.9%), which suggests that the amount of sampling error in estimating the population mean using a sample of 400 observations is relatively small.

Chairs need to be set up for the audience members. You want to use. the fewest number of chairs and still meet these three additional condions.
• There are 23 rows of chairs.
• There are the same number of chairs in esch row.
• There are an even number of chairs in cads rom.
Based on the number of students expected to attend, design a plan to set up the chairs. State how many total chairs there are, and explain why your plan meets these conditions.

Answers

There must be 46 chairs in each row and total number of chairs are 1058

To meet the given conditions, we need to find a number that has the following properties:

It should be divisible by 2, as there are an even number of chairs in each row.

It should be divisible by 23, as there are 23 rows of chairs.

It should be the same number in each row.

The smallest number that satisfies these conditions is 46, which is the least common multiple of 2 and 23.

So, we need to set up 46 chairs in each row.

The total number of chairs required will be:

Total number of chairs = 23 rows x 46 chairs per row = 1058 chairs

Hence, the total number of chairs are 1058

For 4. y = -x² - 8x -16

Axis of symmetry

x = -b / (2a)

x = -(-8) / (2 × -1) = 8 / (-2) = -4

Vertex

y = -(-4)² - 8(-4) - 16

= -16 + 32 - 16

= 0  therefore Vertex is (-4, 0)

Therefore range function  (-∞, ∞)

The above answers are for the questions below as seen in the picture

Which of the following gives the circumference, C, of a circle with a radius of 4?
OC 4T
OC=4T²
OC=8T
O C=16T

Answers

The circumference of a circle with a radius of 4 is 8π.

What is the circumference of a circle with a radius of 4?

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is the distance around a circle or the length of a circle. It is expressed mathematically as;

C = 2πr

Where r is radius and π is constant pi.

Given that the radius of the circle is 4 units.

Plug into the above formula.

C = 2πr

C = 2 × π × 4

C = 8π

Therefore, the circumference is 8π.

Answers

Given the function h(x) = -2√(x + 3) - 1, the statement that is true about h(x) include the following: B. the function is decreasing on the interval (-3, ∞).

What is a decreasing function?

For any given function, y = f(x), if the output value (range or y-value) is decreasing when the input value (domain or x-value) is increased, then, the function is generally referred to as a decreasing function.

For any given function, y = f(x), if the output value (range) is increasing when the input value (domain) is increased, then, the function is generally referred to as an increasing function.

By critically observing the graph of the given function, we can reasonably infer and logically deduce that it is decreasing over the interval (-3, ∞).
