Answer:

The measure of arc AB is [tex]88\°[/tex]

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<ACB=\frac{1}{2}(arc\ AB)[/tex]

we have

[tex]m<ACB=44\°[/tex]

substitute

[tex]44\°=\frac{1}{2}(arc\ AB)[/tex]

[tex]88\°=arc\ AB[/tex]

rewrite

[tex]arc\ AB=88\°[/tex]

The measure of arc AB is 88°

The inscribed angle measures half that of the arc comprising

so

[tex]m < ACB=(1)/(2)(arc\ AB)[/tex]

we have

[tex]m < ACB=44°[/tex]

substitute

[tex]44\°=(1)/(2)(arc\ AB)[/tex]

[tex]88\°=arc\ AB[/tex]

To express both logarithms in terms of the natural logarithm (for example, any common base would be fine:

[tex]\log_c(x) = \dfrac{\ln(x)}{\ln(c)},\quad \log_d(x) = \dfrac{\ln(x)}{\ln(d)}[/tex]

Since the natural logarithm is an increasing function, we have

[tex]c<d\implies \ln(c)>\ln(d)[/tex]

which implies

[tex]\dfrac{\ln(x)}{\ln(c)}=\log_c(x)<\log_d(x)=\dfrac{\ln(x)}{\ln(d)}[/tex]

Answer:

(-2, 0)

Step-by-step explanation:

Because both equations are to find Y, set them equal to each other to solve:

3x+6 = x+2

Subtract x from both sides:

2x + 6 = 2

Subtract 6 from both sides:

2x = -4

Divide both sides by 2:

x = -4 /2

x = -2

Now you have a value for x, replace X with -2 in one of the equations and solve for y:

y = 3x +6 = 3(-2) +6 = -6 +6 = 0

X = -2 and Y = 0

(-2,0)

Answer:

9.09%

Step-by-step explanation:

You over estimated by 2 feet.  Find out how much 2 feet of 22 is by dividing 2 by 22...

2/22 = 0.090909090909

To convert a decimal to a percent, multiply the decimal by 100%

0.0909090909(100%) = 9.0909090909% or 9.09%

Final answer:

The percent error in the student's estimate of the board's length is approximately 9.09%. The exercise demonstrates the value of precise calculations over rough estimates, although some thoughtful guesses can be quite close.

Explanation:

To find the percent error of the student's estimate, we'll use the following formula:

Percent Error = |(Actual Value - Estimated Value) / Actual Value| × 100%

The actual length of the board is 22 feet, and the estimated length is 24 feet. So we can calculate the percent error as follows:

|(22 - 24) / 22| × 100% = |(-2) / 22| × 100% = (2 / 22) × 100% ≈ 9.09%

The percent error in the student's estimate is approximately 9.09%. This calculation underscores the importance of making careful calculations rather than relying on rough guesstimates, which can lead to significant errors in certain situations. However, it can also show that even guesses made with some thought, like the example of 10 feet versus an actual of 12 feet, can sometimes be surprisingly close.

Answer:

The answer is vertical translation down 9 units  ⇒ answer (d)

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) - k

* Lets study the problem

- The basic function is y = csc(x)

∵ y = csc(x) - 9

- That means the function translated vertically 9 units down

* Vertical translation 9 units down

* Look to the graph

-The red graph is y = csc(x)

- The green graph is y = csc(x) - 9

The value of x is 2.

(132°-x)+(6x-12°) = 180°(Co-interior Angles)

132°-12°-x+6x = 180°

120° + 5x = 180°

5x = 180° - 120°

5x = 60°

x = 12°

(132°-x)+(6y+18°) = 180°(Co-interior Angles)

132°-x+6y+18°=180°

132°-12°+18°+6y=180°

138°+6y=180°

6y=180°-138°

Answer:

9,150,625.

Step-by-step explanation:

Any  one of the 55 numbers can be combined with any one of the 55 in the other cylinders.

So the number of different combinations are 55^4

= 9,150,625.

The total number of different combinations that can be made with a four-cylinder combination lock that has 55 numbers on each cylinder is 9,150,625. This is calculated using the multiplication principle of counting.

This question involves the principle of counting or combinatorics in mathematics. Specifically, it relates to the multiplication principle, which says that if event A can occur in m ways, and after it happens, event B can occur in n independent ways, then the total number of ways in which both events can occur is calculated as m times n.

In the case of the four-cylinder combination lock with 55 possible numbers for each cylinder, there are 55 ways to choose a number for the first cylinder. Since repetitions are allowed and each choice is independent, there are also 55 ways to choose a number for the second cylinder, 55 ways for the third cylinder, and 55 ways for the fourth cylinder. Using the multiplication principle, we can find the total number of possible lock combinations by calculating 55 * 55 * 55 * 55 = 9,150,625 possible combinations.

The solution to the given system of linear equations is (3, 2), which is found by eliminating y and solving for x, then substituting back to find y.

Given the system of equations:

x + 2y = 7
x - 2y = -1

To find the solution to the system, we can add the two equations to eliminate y:

(x + 2y) + (x - 2y) = 7 + (-1)
2x = 6
x = 3

Substituting x = 3 into the first equation:

3 + 2y = 7
2y = 4
y = 2

So, the solution to the system of equations is (3, 2). None of the other provided options, {(-8, -12)} or {(-4, 6)}, match this solution.

-1.144 , 1.144

Step-by-step explanation:

Since we are dealing with trascendental equations, it is best if we solve the problem graphically with the help of a calculator or any plotting tool.

Please, see attached image

We graph both equations and find the intersection between them in the interval from -pi to pi

This will give the solution to the equation

tan(x) = 2* csc(x)

The answer is

x = -1.144

x =  1.144

The question requires solving a trigonometric equation tan x = 2 csc x by using trigonometric identities to express it in terms of sine and cosine and then finding the approximate solutions within the interval -π to π.

The student is asking for an approximate solution for a trigonometric equation within a specified interval. The equation given is tan x = 2 csc x. To solve this trigonometric equation, you need to use trigonometric identities to express both sides of the equation in terms of a single trigonometric function and then find the values of x that satisfy the equation within the given interval.

To start with, we can use the identity csc x = 1/sin x and then rewrite the equation as tan x = 2/sin x. Since tan x = sin x/cos x, we can now express the equation purely in terms of sine and cosine:

sin x/cos x = 2/sin x

Multiplying both sides by sin x cos x, we obtain sin2 x = 2 cos x. From here, we can use numerical methods or graphing techniques to find an approximate solution for x within the interval -π to π.

Answer:

l = 4, w = 14

Step-by-step explanation:

[tex]A_r = 56 = l * w[/tex]

l - length;

w - width;

l = w - 10;

We substitute the 'l' using the previous formula =>

[tex][tex]A_r = (w -10) \cdot w = w^2 - 10w = 56 =>\\w^2 - 10w - 56 = 0\\[/tex]

By the quadratic formula we solve for 'w':(we will use the positive value, because we're talking about lengths of planes in a Euclidean space)

[tex]w = \frac{10 + \sqrt{100+224} }{2} =  \frac{10+18}{2} = \frac{28}{2} = 14[/tex]

l = w - 10 = 14 -10 = 4

Answer:

The speeds are 34 mph for the slower car and 68 mph for the faster car.

Step-by-step explanation:

speed = distance/time

Using s for speed, d for distance, and t for time, we have the equation for speed:

s = d/t

Solve for distance, d, by multiplying both sides by t.

d = st

Now we use the given information.

Speed of slower car: s

Speed of faster car: 2s

Distance traveled by faster car: d

Distance traveled by slower car: d - 204

time traveled by faster car = time traveled by slower car = 6

Distance equation for faster car:

d = st

d = 2s * 6

d = 12s     <---- equation 1

Distance equation for slower car:

d = st

d - 204 = s * 6

d - 204 = 6s

d = 6s + 204    <----- equation 2

Now, using equations 1 and 2, we have a system of two equations in two unknowns.

d = 12s

d = 6s + 204

Since the first equation is already solved for d, we can use the substitution method. Substitute 12s for d in the second equation:

12s = 6s + 204

6s = 204

s = 34

The speed of the slower car is 34 mph.

The speed of the faster car is

2s = 2(34) = 68

The speed of the faster care is 68 mph.

Two cars started moving simultaneously where one was twice as fast as the other. After setting x as the speed of the slower car, the equations showed the slower car traveled at 34 mph and the faster car at 68 mph, based on being 204 miles apart after 6 hours.

Two cars started moving at the same time and direction where one car's speed was twice as fast as the other. After 6 hours, they were 204 miles apart. To solve for the speed of each car, let's set up an equation where the speed of the slower car is x miles per hour and the faster car is 2x miles per hour.

The distance covered by each car after 6 hours would then be:

Since the cars are 204 miles apart after 6 hours, the equation can be set up as:

12x - 6x = 204

So the distance difference is:

6x = 204

Divide both sides by 6 to find the speed of the slower car:

x = 34

Therefore, the slower car travels at 34 mph and the faster car travels at 68 mph (twice the speed of the slow car).

Answer:

5π/2 it is not a solution for the equation 2sin²x - sinx - 1 = 0

Step-by-step explanation:

∵ 2sin²x - sin x - 1 = 0

* Lets factorize it as a quadratic equation

∴ ( 2sinx + 1)(sinx - 1) = 0

∴ 2sinx + 1 = 0 ⇒ 2sinx = -1 ⇒ sinx = -1/2

* ∵ The value of sinx is -ve

  ∴ x is in the 3rd or 4th quadrant ⇒ According to ASTC Rule

- ASTC Rule:  1st all +ve , 2nd sin only +ve ,

                      3rd tan only +ve , 4th cos only +ve

* Let sinα = 1/2 where α is an acute angle

∴ α = π/6

∵ x is in 3rd or 4th quadrant

∴ x = π + α = π + π/6 = 7π/6 or

∴ x = 2π - π/6 = 11π/6

OR

∴ sinx - 1 = 0 ⇒ sinx = 1

∴ x = π/2

∴ ALL values of x are π/2 , 7π/2 , 11π/2 if 0 ≤ x ≤ 2π

∴ 5π/2 it is not a solution for the given equation

Since n < 30, we will find the t-score and compare that to the t-score of a significance level of 1%.    

Since they are asking if the difference is significant, we will have a two tailed test, with degree of freedom being 22, so our critical values are

t < -2.704 and t > 2.704

Our t-value for this situation is

t = ([µ + 5.8] - µ)/(1.4/√23)

It's µ + 5.8 because the problem told us that their levels are 5.8 mm higher than the average, so it's the average, plus 5.8

Simplify the equation...

t = 5.8/(1.4/√23)

t = 19.868

19.868 > 2.704, the evidence supports that there is significant difference between the sample and the population

There is a significant difference between the sample and the population.

A standard deviation (or σ) indicates how dispersed the data is in relation to the mean.

The t-distribution indicates the standardized distances of sample means to the population mean when the population standard deviation is not known, and the observations come from a normally distributed population.

A t-score is the number of standard deviations away from the mean of the t-distribution.

Here the degree of freedom is 22 and so the critical values are:

t < -2.704 and t > 2.704

∴ The t-value for this situation is

t = ([µ + 5.8] - µ)/(1.4/√23)

⇒ t = 5.8/(1.4/√23)

⇒t = 19.868

So, we can say that there is significant difference between the sample and the population.
