1. Solve triangle ABC if A = 42.3º, b = 12.9 meters, and c = 15.4 meters.
this is trigonometry, you have to use the cosine law to solve it
Answer:
a = 10.36m
B = 47.7º
C = 90º
Step-by-step explanation:
we know the angle of A so we do the sin of A; Spoiler: its 0.67
0.67 = a / 15.4
0.67 * 15.4 = a
a = 10.36
----------
B = 90 - 42.3 = 47.7º
I recently took a review test and it talked about amount of error (percent error) . The question said that , “the estimate number of balls in each bag was 86. It turned out to be 104. What is the percent of error? Round to the nearest tenth.” I wrote 17.3%. The teacher said it was wrong and claimed that you had to divide it by expected, not real. (Formula is (expected-real)/real.)) Can someone help me out, am I wrong or the teacher?
The percent of error is 20.9302%. The solution has been obtained by using percent error.
What is percent error?
The difference between the estimated value and the actual value in respect to the actual value is known as the percent error.
We are given that the estimate number of balls in each bag was 86 but it turned out to be 104.
So, the percent error is
⇒Percent error = [Estimated Value - Actual value] / Actual value
⇒Percent error = [104 - 86] / 86
⇒Percent error = 18 / 86
⇒Percent error = 20.9302%
Hence, the percent of error is 20.9302%.

Find the measures of the angles of the triangle whose vertices are A=(−2,0),B=(3,2), and C=(3,−3). The measure of ∠ABC is (Round to the nearest thousandth.)
The measure of ∠ABC in the triangle ABC is approximately 59.804 degrees.
To find the measures of the angles of the triangle ABC, we can use the angle formula based on the coordinates of the vertices. Let's calculate the angles step by step:
Find the length of each side of the triangle using the distance formula:
AB = √[(x2 - x1)² + (y2 - y1)²] = √[(3 - (-2))² + (2 - 0)²] = √[5² + 2²] = √(25 + 4) = √29
BC = √[(x2 - x1)² + (y2 - y1)²] = √[(3 - 3)² + (-3 - 2)²] = √[0² + (-5)²] = √25 = 5
AC = √[(x2 - x1)² + (y2 - y1)²] = √[(-2 - 3)² + (0 - 2)²] = √[(-5)² + (-2)²] = √(25 + 4) = √29
Use the law of cosines to find the measures of the angles:
Let's calculate ∠ABC:
cos(∠ABC) = (AB² + BC² - AC²) / (2 * AB * BC)
cos(∠ABC) = (29 + 25 - 29) / (2 * √29 * 5)
cos(∠ABC) = 25 / (2 * √29 * 5)
∠ABC = cos⁻¹(25 / (2 * √29 * 5))
Using a calculator, we can find the value of ∠ABC as approximately 59.804 degrees.
Therefore, the measure of ∠ABC in the triangle ABC is approximately 59.804 degrees.

T/F. Exception reports show a greater level of detail than is included in routine reports.
True. Exception reports show a greater level of detail than is included in routine reports.
Exception reports are reports that help in identifying data that does not conform to expected patterns. Exception reports show information about an exception in the data set.
This helps to identify irregularities or anomalies in data or system operations.Exception reports are used to analyze system performance, monitor resource consumption, and to detect unusual activity.
This type of report is important to identify issues or errors, where the routine reports or standard reports would not provide enough detail or insight to do so.
It provides detailed information on any unusual event or anomaly that occurred beyond the usual course of events or processes.Exception reports are generated and distributed when the data is not expected or when an event occurs that is outside of what is considered typical.
For example, a financial system might generate an exception report if a transaction is entered that exceeds the maximum allowed amount. This report would show the details of the transaction and highlight the exception.
The purpose of exception reports is to provide users with a higher level of detail than they would find in routine reports. Exception reports are used to highlight significant data, which will be used for further analysis or action.

Answer:

Step-by-step explanation:
Square root of(x^2-4x-5)=2x-10
Answer:
x = 7
x = 5
Step-by-step explanation:
\(\sqrt{x^2-4x-5}=2x-10\)
We square both sides to get rid of the square root.
\((\sqrt{x^2-4x-5})^2=(2x-10)^2\)
\(x^2-4x-5=(2x-10)^2\)
We know (a + b)^2 = a^2 + 2ab + b^2 so now the right side becomes,
\(x^2-4x-5={(2x)^2-2(2x)(10)+(10)^2}\\\)
\(x^2-4x-5=4x^2-40x+100\\\)
Now move everything to the right side,
\(4x^2-x^2-40x+4x+100+5=0\\3x^2-36x+105=0\\\)
Now we can take 3 common ,
\(3(x^2-12x+35)=0\\x^2-12x+35=0\)
now this is a simple quadratic equation, we can use two methods.
1) Quadratic formula
2) Factorize
We use the factorizing method,
we need two numbers when multiplied give us +35 and when added give us -12 so the numbers are -7 and -5 because -7 x -5 = +35 and
- 7 - 5 = -12
\(x^2-7x-5x+35=0\)
\(x(x-7)-5(x-7)=0\\(x-7)(x-5)=0\\x-7=0 \ \ \ , \ \ \ x-5=0\\x=7 \ \ \ \ \ \ \ \ , \ \ \ \ x=5\)
What is the product? 6x[4-21 730]
Answer:C
Step-by-step explanation:
4×6≈24...To find the product of 6x and [4-21 730], we need to simplify the expression first.
To simplify, we perform the subtraction first and then multiply.
So, [4-21 730] can be simplified as follows: [4-21 730] = 4 - 21730 = -21726
Now, we can find the product of 6x and -21726 as follows: 6x(-21726) = -130356
Therefore, the product of 6x and [4-21 730] is -130356.
Find an equation of the line perpendicular to the line 3x+6y=5 and passing through the point (1,3). Write the equation in the standard form.
The standard form of the equation of a line perpendicular to the line (3x + 6y = 5) and passing through the point (1, 3) is (2x - y = -1)
To determine the equation of a line perpendicular to the line (3x + 6y = 5) and passing through the point (1, 3), we can follow these steps:
1. Obtain the slope of the provided line.
To do this, we rearrange the equation (3x + 6y = 5) into slope-intercept form (y = mx + b):
6y = -3x + 5
y =\(-\frac{1}{2}x + \frac{5}{6}\)
The slope of the line is the coefficient of x, which is \(\(-\frac{1}{2}\)\).
2. Determine the slope of the line perpendicular to the provided line.
The slope of a line perpendicular to another line is the negative reciprocal of the slope of the provided line.
So, the slope of the perpendicular line is \(\(\frac{2}{1}\)\) or simply 2.
3. Use the slope and the provided point to obtain the equation of the perpendicular line.
We can use the point-slope form of a line to determine the equation:
y - y1 = m(x - x1)
where x1, y1 is the provided point and m is the slope.
Substituting the provided point (1, 3) and the slope 2 into the equation, we have:
y - 3 = 2(x - 1)
4. Convert the equation to standard form.
To convert the equation to standard form, we expand the expression:
y - 3 = 2x - 2
2x - y = -1
Rearranging the equation in the form (Ax + By = C), where A, B, and C are constants, we obtain the standard form:
2x - y = -1

Find the H.C.F. of 567 and 255 using Euclid’s division lemma.
Step-by-step explanation:
To find the Highest Common Factor (H.C.F.) of 567 and 255 using Euclid's division lemma, we can follow these steps:
Step 1: Apply Euclid's division lemma:
Divide the larger number, 567, by the smaller number, 255, and find the remainder.
567 ÷ 255 = 2 remainder 57
Step 2: Apply Euclid's division lemma again:
Now, divide the previous divisor, 255, by the remainder, 57, and find the new remainder.
255 ÷ 57 = 4 remainder 27
Step 3: Repeat the process:
Next, divide the previous divisor, 57, by the remainder, 27, and find the new remainder.
57 ÷ 27 = 2 remainder 3
Step 4: Continue until we obtain a remainder of 0:
Now, divide the previous divisor, 27, by the remainder, 3, and find the new remainder.
27 ÷ 3 = 9 remainder 0
Since we have obtained a remainder of 0, the process ends here.
Step 5: The H.C.F. is the last non-zero remainder:
The H.C.F. of 567 and 255 is the last non-zero remainder obtained in the previous step, which is 3.
Therefore, the H.C.F. of 567 and 255 is 3.

Rounded to the nearest cent, the monthly finance charge is $1.88.To calculate the monthly finance charge for this credit card, we need to use the adjusted balance method.
This means we take the balance at the beginning of the billing cycle and subtract any payments made during the cycle. In this case, the balance is $200 and the payment is $50, so the adjusted balance is $150.
Next, we apply the interest rate of 15% to the adjusted balance. To do this, we first convert the annual rate to a monthly rate by dividing it by 12. So, the monthly rate is 15% / 12 = 1.25%.
Finally, we multiply the adjusted balance by the monthly rate to get the finance charge for the billing cycle:
Finance charge = $150 x 1.25% = $1.88
Rounding to the nearest cent, the monthly finance charge for this credit card is $1.88.

Using the information above, how much interest will Shirley "save" or be rebated if she can repay the loans after six months? Click on the table icon to view the MILPF table For a bank loan assuming a one-year repayment period and 13.5% interest, the monthly payment is $ (Round to the nearest cent.)
The monthly payment for a bank loan assuming a one-year repayment period and 13.5% interest is To calculate the monthly payment for a bank loan, we can use the formula:
Monthly payment = Total cost / Number of months
Given that the total cost is $1,800 and the repayment period is one year (12 months), we can substitute these values into the formula:
Monthly payment = $1,800 / 12 = $
Now, let's calculate the total cost for the bank loan:
Total cost = Monthly payment * Number of months
Total cost = $ * 12 = $
For the add-on method of interest calculation with a one-year repayment period and 11.5% interest, the monthly payment is $ (main answer).
The add-on method of interest calculation involves adding the interest to the principal amount and then dividing it by the number of months.
Given that the total cost is $1,800 and the repayment period is one year (12 months), we can calculate the interest as follows:
Interest = Total cost * Interest rate
Interest = $1,800 * 11.5% = $
Now, let's calculate the new principal amount:
New principal amount = Total cost + Interest
New principal amount = $1,800 + $ = $
Finally, we can calculate the monthly payment:
Monthly payment = New principal amount / Number of months
Monthly payment = $ / 12 = $

(a) The lower bound of the confidence interval is 7.917 minutes.
(b) The upper bound of the confidence interval is 8.483 minutes.
(c) The margin of error is 0.283 minutes.
(a) The point estimate of the population mean is 8.2 minutes.
To calculate the lower bound of the 90% confidence interval, we use the formula: lower bound = point estimate - z* (standard error), where z* is the z-score for the 90% confidence level, which is 1.645, and the standard error is equal to the population standard deviation divided by the square root of the sample size, i.e., 2.2 / sqrt(200) = 0.156.
Substituting these values in the formula, we get the lower bound as 8.2 - 1.645 * 0.156 = 7.917 minutes.
(b) To calculate the upper bound of the 90% confidence interval, we use the same formula: upper bound = point estimate + z* (standard error). Substituting the values, we get the upper bound as 8.2 + 1.645 * 0.156 = 8.483 minutes.
(c) The margin of error is the difference between the point estimate and the upper or lower bound of the confidence interval. In this case, it is equal to half the width of the confidence interval, which is (8.483 - 7.917) / 2 = 0.283 minutes.
