Work out the size of angle 0.
Give reasons for your answer.
Answer:
θ = 56°
Step-by-step explanation:
As OA and OB are both radii, triangle AOB is an isosceles triangle:
⇒ m∠ABO = m∠OAB = 48°
Interior angles of a triangle sum to 180°:
⇒ m∠ABO + m∠OAB + m∠AOB = 180°
⇒ 48° + 48° + m∠AOB = 180°
⇒ m∠AOB = 180° - 48° - 48°
⇒ m∠AOB = 84°
Angles on a straight line sum to 180°:
⇒ m∠AOB + m∠DOB = 180°
⇒ 84° + m∠DOB = 180°
⇒ m∠DOB = 180° - 84°
⇒ m∠DOB = 96°
The tangent of a circle is always perpendicular to the radius.
Therefore, tangent BC is perpendicular to radius OB, and tangent DE is perpendicular to radius OD, so:
m∠OBC = 90°m∠ODE = 90°OBCD is a quadrilateral.
The interior angles of a quadrilateral sum to 360°:
⇒ m∠OBC + m∠BCD + m∠CDO + m∠DOB = 360°
⇒ 90° + θ + 28° + 90° + 96° = 360°
⇒ θ + 304° = 360°
⇒ θ = 360° - 304°
⇒ θ = 56°

How do you express .13 as a percentage?
.13 can be expressed in the form of percentage as 13%.
In order to convert numbers in decimal into percentage we only need to multiply the given number with 100 and after multiplying the number with hundred it can be written in percentage form. Like in the question given number is 0.13 and we need to express this in form of percentage. So in order to express this number in percentage we just multiply it with 100 which will be equal to 13% i.e
0.13 x 100 = 13%
By multiplying a decimal value by 100 and adding the percentage (%) sign, you can turn a decimal value into a percentage. A decimal multiplied moves the decimal point two places to the right.

the monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). the monthly cost for 45 minutes of calls is $14.40 and the monthly cost for 102 minutes is $19.53. what is the monthly cost for 66 minutes of calls?
The monthly cost for 66 minutes of calls will be $15.84.
Monthly cost is the payment or the bill amount that needs to be paid at the end of the month.
The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes)
The monthly cost for 45 minutes of calls = $14.40
The monthly cost for 102 minutes = $19.53
The above values can be paired in groups so as to satisfies the coordinates of a linear function
(45,14.40) and (102,19.53)
Finding the slope of the graph using these points
slope, m=Δy/Δx
m=Δy=19.53 - 14.40 = 5.13
Δx=102 - 45 = 57
m = 5.13/57 =0.09
Finding the equation of the linear function using m = 0.09, and point (45,14.40)
m=Δy/Δx
0.09=y-14.40/x-45
0.09(x-45)=y-14.40
0.09x-4.05=y-14.40
0.09x-4.5+14.40=y
y=0.09x + 9.9
So for 66 minutes, the cost will be;
x = 66, y = ?
y=0.09*66 + 9.9
y=5.94+9.9 = $15.84

based on your site data sheet and your sample identification, do you feel that you determine an appropriate stream rating? (why or why not). do you feel using macroinvertebrates is a good method to evaluate stream conditions?
When collecting quantitative data you can use a statistical formula to give you a rough estimate of the sample size you will need. When collecting qualitative data, however, the rule of thumb is to have as representative of a sample as possible that will allow you to exhaust the knowledge you could learn from the population.
Macroinvertebrate sampling provides a relatively easy way to assess the water quality of a stream. The types and numbers of macroinvertebrates (mostly insect larvae/nymphs) that form the biological community at a particular stream location are shaped by both the nature of the stream and the quality of water that drains into the stream.

The Bronsted-Lowry corrosive base hypothesis incorporates the ideas of form acids and form bases. At the point when a corrosive separates into its particles in water, it loses a hydrogen particle. The species that is shaped is the corrosive's form base.
A more broad definition is that a form base is the base part, X-, of a couple of mixtures that change into one another by acquiring or losing a proton. The form base can acquire or retain a proton in a synthetic response. The form corrosive gives the proton or hydrogen in the response.
In a corrosive base response, the substance response is:
Corrosive + Base ⇌ Form Base + Form Corrosive
We know very well that from equilibrium state theories that pk[tex]_b[/tex] +pk[tex]_a[/tex] =14
where pk[tex]_a[/tex] = - log( k[tex]_a[/tex] )
So, we have k[tex]_a[/tex] =5.57×10⁻⁵

Step-by-step explanation:
A theater seats 500 people. Each adult ticket, a, sells for $7.50, and each student ticket, s, for $4.50. On a Friday evening, every seat was filled, and the theater made $3,150 in ticket sales. Which system of equations could be used to find the number of adult and student tickets sold on Friday evening?
a + s = 3,150
7.5a + 4.5s = 3,150
a + s = 500
7.5a + 4.5s = 3,150
a + s = 3,150
7.5s + 4.5a = 500
a + s = 500
7.5a + 4.5s = 500
Answer:
The two equations that can be used are 7.50a + 4.50s = 3150, and
a + s = 500.
----------------------
a + s = 3,150 NO
7.5a + 4.5s = 3,150 YES
a + s = 500 YES
7.5s + 4.5a = 500 NO
Step-by-step explanation:
We know that a + s = 500.
Total sales would be the product of the number of adult and student tickets times their repsective prices:
Total Sales ($) = $7.50a + $4.50s = $3150
Leaving off the units for the next steps, we have two equations and we can rearrange one of them to substitute into the other.
1) Rearrange the first equation to isolate a: a = 500-s
Now use this definition of a in the second equation:
7.50a + 4.50s = 3150
7.50(500-s) + 4.50s = 3150
3750 - 7.5s + 4.50s = 3150
-3s = -600
s = 200 student tickets were sold
Use a+s=500 to find a:
a+200 = 500
a=300 300 adult tickets were sold.
================
The two equations we used to find this answer were:
7.50a + 4.50s = 3150, and
a + s = 500
How do you find the nth term of the sequence 2,4,16,256,... ?
The [tex]n^{th[/tex] term of an exponentially increasing sequence can be found using the formula:
[tex]a_n = a_1[/tex] × [tex]r^(^n^-^1^)[/tex]
To find the [tex]n^{th[/tex] term of a sequence, you can use a formula that defines the relationship between the terms of the sequence. In this particular sequence, the terms seem to be increasing exponentially, with each term being the square of the previous term.
The [tex]n^{th[/tex] term of an exponentially increasing sequence can be found using the formula:
[tex]a_n = a_1[/tex] × [tex]r^(^n^-^1^)[/tex]
where [tex]a_n[/tex] is the nth term of the sequence, [tex]a_1[/tex] is the first term of the sequence, and r is the common ratio.
In this case, the first term is 2, and the common ratio is the previous term divided by the term before it. In this sequence, the common ratio is [tex]\frac{4}2=2[/tex]
Therefore, the [tex]n^{th}[/tex] term of the sequence can be found using the following formula:
[tex]a_n = 2[/tex] × [tex]2^{(n-1)[/tex]
So to find the [tex]n^{th[/tex] term, you would plug in the value of n into the formula. For example, to find the fifth term of the sequence, you would plug in 5 for n:
[tex]a_5 = 2[/tex] × [tex]2^{(5-1)[/tex]
= 2 × [tex]2^4[/tex]
= 2 × 16 = 32
So the fifth term of the sequence is 32

consider the curve defined by y2=x3−3x 3 for x>0. at what value of x does the curve have a horizontal tangent?
At x = 0 and x = 2, the curve defined by y² = x³ - 3x² has a horizontal tangent.
We have,
First, let's find the derivative of y with respect to x.
We can rewrite the equation as:
y² = x³ - 3x²
y = (x³ - 3x²)^(1/2)
Now, differentiating y with respect to x using the chain rule:
dy/dx = (1/2) * (x³ - 3x²)^(-1/2) * (3x² - 6x)
Next, we set the derivative equal to 0 to find the values of x where the curve has a horizontal tangent:
(1/2) * (x³ - 3x²)^(-1/2) * (3x² - 6x) = 0
We can disregard the constant factor of (1/2) since it doesn't affect the solution.
Thus, we have:
(x³ - 3x²)^(-1/2) * (3x² - 6x) = 0
To have a horizontal tangent, the slope of the curve should be 0, which means the derivative is equal to 0.
Now, we have two factors to consider:
(x³ - 3x²)^(-1/2) = 0, which means the expression inside the parentheses is equal to 0. However, this does not yield a real solution.
(3x² - 6x) = 0, which means the quadratic term equals 0.
Solving this quadratic equation:
3x² - 6x = 0
3x(x - 2) = 0
This equation has two solutions: x = 0 and x = 2.
Therefore,
At x = 0 and x = 2, the curve defined by y² = x³ - 3x² has a horizontal tangent.

queuing system a has a utilization of 80 percent, and queuing system b has a utilization of 90 percent. both have a single server. say the utilization of both systems increases by 5 percent; that is, a increases from 80 percent to 85 percent while b increases from 90 percent to 95 percent. which system is likely to experience the bigger change in the average time in queue?
For queuing system B, the average time in queue ids going to change significantly as a result of increased utilization.
This is because queuing system B is initially heavily loaded and has less capacity to handle more requests. As a result, an increase in utilization can cause a significant increase in average queue latency on system B compared to system A.
Average Queue Time is a measure of the time a customer or request spends being processed by a server. It is affected by several factors such as server load, customer or request arrival rate, and server service rate. As the load on the queuing system increases, it means that the server is being used more frequently and is no longer available to process incoming requests. This will increase the average time in the queue as more requests accumulate and have to wait to be processed. The greater the increase in occupancy, the greater the impact on average latency.

The transition to -24 degrees will take three hours .The balance between energy coming into and going out of the planet's system determines its temperature.
What influences how the temperature fluctuates?The balance between energy coming into and going out of the planet's system determines its temperature. The Earth warms up when incoming solar energy is absorbed by the Earth system. Earth does not warm as a result of solar energy being reflected back into space. Earth cools as energy that has been absorbed is ejected back into space.Since 1880, the Earth's average temperature has increased by 0.14° F (0.08° C) every decade; however, since 1981, the pace of warming has increased by 0.32° F (0.18° C) per decade, or more than twice as fast. Using NOAA's temperature data, 2021 ranked as the sixth-warmest year ever.Explanation:

How do you simplify (2−i) / (5+i) ?
To simplify [tex]\frac{2-i}{5+i} = \frac{9}{26} -\frac{7}{26} i[/tex] , multiply the numerator and denominator by the conjugate of the denominator.
A complex number's conjugate A+bi equals a-bi. A real number is the result of a complex number and its conjugate. That fact will be used here.
[tex]\frac{2-i}{5+i} =\frac{2-i}{5+i} . \frac{5-i}{5-i}[/tex]
[tex]= \frac{(2-i)(5-i)}{(5+i)(5-i)}[/tex]
[tex]=\frac{10-2i-5i-1}{25-5i+5i+1}[/tex]
[tex]=\frac{9-7i}{26}[/tex]

The graph of Stewart's assignment added as an attachment
How to draw the graph of the scenario?From the question, we have the following parameters that can be used in our computation:
Number of assignments = 36
Rate of assignment per day = 4
This means that the equation of the scenario is
Number of assignments remaining = Initial number of assignments - Rate of assignment per day * Number of days
Represent the number of assignments remaining with y and the number of days with x
So, we have the following representation
y = Initial number of assignments - Rate of assignment per day * x
Substitute the known values in the above equation, so, we have the following representation
y = 36 - 4 * x
Evaluate the products
y = 36 - 4x
So, the equation is y = 36 - 4x and the graph is added as an attachment
