What is the value of x? (Only type the numerical value. Do not type x= before your answer)

Answer:

[tex]A=53.13\°[/tex]

Step-by-step explanation:

The figure shows a right triangle.

To calculate the measure of the angle A, you can use the inverse trigonometric function arctangent:

[tex]\alpha=arctan(\frac{opposite}{adjacent})[/tex]

Identify the angle [tex]\alpha[/tex], the opposite side and the adjacent side:

[tex]\alpha=A\\opposite=4cm\\adjacent=3cm[/tex]

Substitute into [tex]\alpha=arctan(\frac{opposite}{adjacent})[/tex].

The measure of the angle A is:

[tex]A=arctan(\frac{4}{3})\\\\A=53.130\°[/tex]

Rounded to the nerarest hundreth:

[tex]A=53.13\°[/tex]

The answer is m∠A = 53.13 °

We kinda need the graph

Answer:

If the angle is in degrees, when taking the tangent, make sure your calculator is in Degree mode.

Answer:

$386794

Step-by-step explanation:

To be able to find how much we get in 5 years, we need to base it off the initial salary value.

So in the first year we get.

$70,000

To get how much we get in the 2nd year we add the extra 5%.

2nd year salary = (1.05)70000

2nd year salary = 73500

Now we continue to do that until the 5th year

3rd year = (1.05)73500

3rd year = 77175

4th year = (1.05) + 77175

4th year = 81033.75

5th year = (1.05) + 81033.75

5th year = 85085.44

Now we add them all up to get the total.

70000 + 73500 + 77175 + 81033.75 + 85085.44 = $386794.19 or $386794

Answer:

Sample mean for solution 1:  19.27; sample mean for solution 2:  10.32

Step-by-step explanation:

To find the sample mean, find the sum of the data values and divide by the sample size.

For solution 1, the sum is given by:

9.7+10.5+9.4+10.6+9.3+10.7+9.6+10.4+10.2+10.5 = 192.7

The sample size is 10; this gives us

192.7/10 = 19.27

For solution 2, the sum is given by:

10.6+10.3+10.3+10.2+10.0+10.7+10.3+10.4+10.1+10.3 = 103.2

The sample size is 10, this gives us

103.2/10 = 10.32

The sample mean for Solution 1 is 10.05 mils per minute, while the sample mean for Solution 2 is 10.32 mils per minute. These figures represent the average etch rates of each solution in the semiconductor manufacturing process. So here the sample mean should be calculated.

To calculate the sample means of Solution 1 and Solution 2, we first sum up the etch rates of each solution, and then divide by the number of samples in each solution.

For Solution 1, the etch rates sum up to 100.5 mils per minute. Dividing this by 10 (number of samples), we get a sample mean of 10.05 mils per minute.

For Solution 2, the etch rates sum up to 103.2 mils per minute. Dividing this by 10 (number of samples), we get a sample mean of 10.32 mils per minute.

So, the sample means for Solution 1 and Solution 2 are 10.05 and 10.32 mils per minute respectively. These means are useful to compare the average efficiency of these two solutions as a part of normal distribution analysis in the semiconductor manufacturing process.

Answer:

Option b (4,1)

Step-by-step explanation:

The region given by the system of inequalities is shown in the graph. We must look within this region for the point that minimizes the objective function [tex]f(x, y) = 8x + 8y[/tex]

The minimum points are found in the lower vertices of the region.

These vertices are found by equating the equations of the lines::

[tex]3x+2y=14\\-5x +5y=10[/tex]

-------------------

[tex]x = 2\\y = 4[/tex]

[tex]-8x + 3y = -29\\3x + 2y = 14[/tex]

---------------------

[tex]x = 4\\y = 1[/tex]

The lower vertices are:

(4, 1) (2, 4)

Now we substitute both points in the objective function to see which of them we get the lowest value of [tex]f(x, y)[/tex]

[tex]f(4, 1) = 8(4) +8(1) = 40\\f(2, 4) = 8(2) + 8(4) = 48[/tex]

Then the value that minimizes f(x, y) is (4,1).

Option b

Answer:

Step-by-step explanation:

For f(x) = 4x + 3 and g(x) = 9x

(a) (f o g) (x)

= f (g (x))

= f (9x)

= 4(9x) +3

= 36x + 3

Its domain is any real number.

(b) (g o f) (x)

= g (f (x))

= g (4x + 3)

= 9 (4x + 3)

= 36x + 27

Again its domain is any real number.

(c) (f o f) (x)

= f (f (x))

= f (4x + 3)

= 4(4x + 3) + 3

= 16x + 12 + 3

= 16x + 15

Again its domain is any real number.

(d) (g o g) (x)

= g ( g (x))

= g (9x)

= 9(9x)

= 81x

Again its domain is any real number.

Answer:

solution given:

f(x) = 4x + 3

g(x) = 9x

answer:

a.fog(x)=f(9x)=4×9x+3=36x+3

domain=real number

b.gof (x)=g(4x+3)=9(4x+3)=36x+26

domain=real number

c.fof(x)=f(4x+3)=4(4x+3)+3=16x+12+3

=16x+15

domain: real number

The false statement among the options given is 'None of the other 3 statements here are false', because all the other three statements about the geometric series are actually true.

The question presents a geometric series: 1, 2, 4, ... Each term is double the previous term, which means that for this series, the common ratio (r) is 2. Now let us analyze the statements given:

S600 > a600: The sum of the first 600 terms of the series will be greater than the 600th term.

This is true, since the sum of a geometric series to n terms is given by the formula Sn = a1(1 - rn)/(1 - r) for r > 1, where Sn is the sum of the first n terms, a1 is the first term, and r is the common ratio.

Since the sum involves multiple terms and all terms are positive, it will be bigger than the last term.

S600 > S599: The sum of the first 600 terms will be greater than the sum of the first 599 terms.

This is also true, since each term added to the series is positive, so the sum will increase.

S1 = a1: The sum of the first term equals the first term itself.

This is true because the first term of the series is 1, and the sum of just one term (i.e., the first term) is the term itself.

Therefore, the false statement is 'None of the other 3 statements here are false' because actually, none of the other three statements provided are false.

Final answer:

The presented geometric series has a common ratio greater than 1, so the sum of the first 600 terms is greater than the 600th term; similarly, the sum of 600 terms is greater than the sum of 599 terms. Since all provided statements are true, the answer is that 'None of the other 3 statements here are false'.

Explanation:

The question presents a geometric series with the first term 1 and a common ratio of 2. This series is 1+2+4+8+... and so on. We are asked to identify which of the given statements is false regarding the series.

S600 > a600: This statement says that the sum of the first 600 terms is greater than the 600th term. In a geometric series where the common ratio is greater than 1, the sum of the first n terms is indeed greater than the nth term, so this statement is true.S600 > S599: This statement indicates that the sum of the first 600 terms is greater than the sum of the first 599 terms. Since each term in the series is positive, adding another term will always increase the sum, thus this statement is also true.

S1 = a1: This statement equates the sum of the first term to the first term itself. Since there's only one term involved, they are the same. Therefore, this statement is true.

By process of elimination, since the other statements are true, the correct answer would be 'None of the other 3 statements here are false'.

Answer:

2.8 putts in average on any given green

Step-by-step explanation:

To calculate how many putts Madison will need on any given green, we need to calculate the weighted average of his putts.

We use a global sample of 100 puts and factor in the fact he had a one-putt performance 15% of the time, two-putts 20% of the time and so on.

So, the calculation goes like this:

[tex]\frac{1 * 15 + 2 * 20 + 3 * 35 + 4 * 30}{100}  = \frac{280}{100}  = 2.8[/tex]

So, he'll need an average of 2.8 putts in average on any given green.

Which makes sense since 65% of the time, he needs 3 putts or more on the green.

The expected number of putts Madison will need for any given green is 2.85. This is calculated by multiplying each possible outcome by its probability and then summing these values.

The subject of this question is the calculation of an expected value in the context of a game of golf. The expected value is a weighted average, taking into account the probability of each event. Expected value calculations are common in probability and statistics.

In Madison's case, the expected number of putts can be calculated with the following formula:

E(X) = Σ [x * P(X = x)], where x is the outcome (number of putts) and P(X = x) is the probability of that outcome.

Applying the probabilities and outcomes given: E(X) = 1(0.15) + 2(0.20) + 3(0.35) + 4(0.30) = 2.85

So, the expected value of the number of putts Madison will need for any given green is 2.85.

To determine the number of apples John picks on the 10th day, we use the formula for the nth term of an arithmetic sequence. Given the first day's pick at 150 apples and an increase of 100 apples each day, we find that John picks 1050 apples on the 10th day.

An arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a constant difference to the preceding term.

In this case, the first term (the number of apples picked on the first day) is 150, and the common difference (the increase each day) is 100 apples.

To find the number of apples picked on the 10th day, we use the formula for the nth term of an arithmetic sequence, which is:

an = a1 + (n - 1) × d

Where an is the nth term, a1 is the first term, n is the term number, and d is the common difference. For the 10th day:

a10 = 150 + (10 - 1) × 100

a10 = 150 + 9 × 100

a10 = 150 + 900

a10 = 1050

Therefore, John picks 1050 apples on the 10th day.

we don't have an f⁻¹(x), darn!! but but but, we do have an f(x) on the left-hand-side graph, and it has a pair where y = 2, namely ([ ] , 2), so then, f⁻¹(x) will have the same pair but sideways, let's inspect f(x).

hmmmmmm when y = 2, x = 0, notice the y-intercept on the graph, ( 0, 2 ).

so then, that means that f⁻¹(x) has a pair sideways of that, namely ( 2, 0), or f⁻¹(2) = 0.

so then, g(  f⁻¹(2)  ), is really the same as looking for g(  0  ), well then, what is "y" when x = 0 on g(x)?  let's inspect the right-hand-side graph.

Arrange the terms in descending powers of x and y.

x² + 24x  + y² + 64y = -137

Complete the squares  for x and y

(x² + 24x  + 144) + (y² + 64y + 1024) = -137 + 144 + 1024

Write the equation as the  squares of binomials of x and y

Answer: 2830.40

Step-by-step explanation:

By using mathematical formulas for calculating compound interest and the total payment of an installment loan, and then subtracting the original loan principal, the total interest paid on the loan is identified as $9,830.40.

To solve this problem, use the formula for the compound interest on a loan: A = P(1 + r/n)^(nt), where:

Since Randy is not going to start paying off his loan until 10 months later, the money will compound for 20 years and 10 months. Convert 10 months into years we get 10/12 = 0.833 years. Therefore, t = 20 + 0.833 = 20.833 years.

The loan was compounded monthly which means n = 12 and the rate is r = 3.6/100 = 0.036. Now you can substitute these values into the formula.

Next, find the total amount paid over the entire period of the loan by using the formula for the total payment of an installment loan: M = P*r*(1 + r)^n / [(1 + r)^n – 1], where M is monthly payment.

Subtract the principal from the total payment to find the total interest paid. From the given options, it appears that the answer is B.) $9,830.40

Answer:

2.25 hours for the man and 1.83 hours for the woman.

Step-by-step explanation:

We first find the number of calories consumed by both the man and the woman.

The man's calories are:

750+400+225 = 1375

The woman's calories are:

370+400+0 = 770

The man burns 610 calories per hour.  This means to find the number of hours, we divide the number of calories by the rate burned per hour:

1375/610 = 2.25 hours

The woman burns 770 calories per hour.  This means to find the number of hours, we divide the number of calories by the rate burned per hour:

770/420 = 1.83 hours

A 190-pound man needs to shovel snow for approximately 2.25 hours, and a 130-pound woman needs to shovel for approximately 1.83 hours to burn off the calories from their Burger King meal.

The question involves calculating the time it takes for a 190-pound man and a 130-pound woman to burn off the calories consumed from a meal at Burger King through the physical activity of shoveling snow. The man consumed a total of 1375 Calories (750 Cal for BK Big Fish sandwich, 400 Cal for medium french fries, and 225 Cal for a large Coke). The woman consumed a total of 770 Calories (370 Cal for a basic hamburger, 400 Cal for medium french fries, and 0 Cal for a diet Coke).

To find out how long each person needs to shovel snow to burn off the lunch calories, we divide the total number of calories consumed by the rate at which they burn calories while shoveling snow.

For the man: 1375 Calories / 610 Cal/h = approximately 2.25 hours.

For the woman: 770 Calories / 420 Cal/h = approximately 1.83 hours.

Answer:

35

Step-by-step explanation:

First, we will define range.

The difference between the highest and lowest values in a data is called range. To find the range, first the highest and lowest values are found from data, then the lowest value is subtracted from the highest value.  

In the above data,

Highest Value=71  

Lowest Value=36  

Range=Highest value-lowest value  

=71-36  

=35  

The range in the number of fish across the 12 large aquariums is 35, calculated by subtracting the minimum number of fish, 36, from the maximum number, 71.

The question asks us to calculate the range in the number of fish across 12 large aquariums at a zoo. To find the range, we need to identify the largest and smallest numbers in the given data set and then subtract the smallest from the largest.

Here is the list of the numbers of fish in each aquarium: 37, 58, 62, 36, 42, 71, 56, 58, 69, 66, 47, 68.

First, we find the maximum and minimum values:

Maximum (the largest number of fish in an aquarium): 71

Minimum (the smallest number of fish in an aquarium): 36

Next, we calculate the range by subtracting the minimum value from the maximum value:

Range = Maximum - Minimum

Range = 71 - 36

Range = 35

Therefore, the range in the number of fish across the 12 aquariums is 35.
