Step-by-step explanation:
Given an ABCD inscribed quadrilateral, where the AB side is the diagonal of the circum-circle of the quadrilateral, we can calculate various properties by using basic trigonometry. Firstly, let us determine the length of BD. Since BCDZ = 120° and BC = 3cm ,we can use Sine rule to find out BD which will be equal to 4 cm. Secondly, we need to find AB and AD sides lengths as well as other angles in order for our calculations to be complete. To do this we will use Cosine rule since all three sides are known: BC=3cm; CD=5cm;BD=4 cm . This gives us a value for angle CBD which is approximately 39° and consequently angle BAD is also 39° since they add up together (BAD+CBD)to 180 degrees due their being opposite each other on a straight line..Finally ,using cosine again with these new values gives us both AB(6)and AD(2).
To summarise : Lengths -AB: 6 cm ; BD : 4 cm ;AD 2CM Angles - BCDZ :120 ° ; CBD & BAD :39 °
In conclusion , given an ABCD inscribed quadrilateral whose one side was already identified as its circumference diameter it was possible through simple trigonometric equations such s Sines Rule or Cosines Rule determine its remaining lengths ans angles accurately .
Find the interest earned on a $50,000 deposited for six years at 4 1/8% interest, compounded continuously. (please help me I have until this Thurs. to turn in answer please show me the steps ☺️ if possible thanks ❣️)
Answer:
$275.00
Step-by-step explanation:
I= P. × T
100×R (
P=Principal ($50,000.00)
T=Time. (6 years)
R=Rate. (1/8%)
l=lnterest. (?)
l= $50,000.00 × 6×1
100. × 8
l= $500.00 ×6
8
l= $62.50 ×6
l= $275.00
Therefore the interest $275.00
the interest earned on a $50,000 deposited for six years at 4 1/8% interest compounded continuously is $14040.97
Given :
Amount $50,000 deposited for six years at 4 1/8% interest, compounded continuously.
Compounded continuously formula is
\(A=Pe^{rt}\)
Where P is the initial amount deposited
'r' is the rate of interest
t is the time period
A is the amount after 't' years
Lets find out A using the given information
\(A=Pe^{rt}\\P=50000\\r=4\frac{1}{8} =\frac{33}{8} \\\)
Divide by 100 to remove %
\(r=0.04125\\t=6\)
Substitute all the values
\(A=50000e^{0.04125\cdot \:6}\\A=50000e^{0.2475}\\A=64040.96811.....\)
Now we find out the interest
I=A-P
\(Interest = 64040.96811-50000=14040.9681\)
Interest = $14040.97

to know more about unitary method
https://brainly.com/question/28276953
Answer:
Step-by-step explanation
1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.
Now let's check if this result is correct:
1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.
So we have shown that each family paid **Rs 13,522** for the trip

Answer:
using the same procedures as for numerical fractions
Step-by-step explanation:
The thing that many Algebra students fail to recognize is that any algebraic expression is subject to the same rules of arithmetic as any numerical value. Addition and subtraction, multiplication and division of rational expressions works exactly the same way as it does with numerical fractions. The notions of "least common denominator" and "cancelling common factors" (to reduce the fraction) also apply.

The sentence translation of "2/3y - 9 < y + 1" is "Nine less than two-thirds of a number is less than the number."
To translate the inequality expression "2/3y - 9 < y + 1" into a sentence, we can break it down into smaller parts:
"2/3y" represents two-thirds of a number.
"9" represents the number nine.
"y + 1" represents the number increased by one.
Now let's construct the sentence:
"Nine less than two-thirds of a number" - This refers to the expression "2/3y - 9," indicating that we have subtracted nine from two-thirds of a number.
"is less than" - This is the comparison symbol in the inequality.
"the number" - This refers to the expression "y + 1," representing the number increased by one.
Combining these parts, we form the sentence: "Nine less than two-thirds of a number is less than the number."

The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8400ft, the liquid boils at 202.92°F. At an altitude of 4400ft, the liquid
boils at 207.72°F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the
liquid at 2200 ft?
Answer:(a) getting the equation:
We'll assume that the altitude is represented by the x-axis and that the boiling point is represented by the y-axis.
Therefore, we have two given points:
(8400 , 200.4) and (4200 , 206.7)
Since the relation is linear, therefore, the graph forms of straight line with the general equation:
y = mx + c where m is the slope and c is the y-intercept.
First, we will calculate the slope:
m = (y2-y1) / (x2-x1) = (206.7 - 200.4) / (4200 - 8400) = -0.0015
Therefore, the equation of the line now is:
y = -0.0015x + c
Then, we will need to calculate the y-intercept. In order to do so, we will use any give point and substitute in the previously obtained equation as follows:
y = -0.0015x + c
206.7 = -0.0015(4200) + c
c = 213
Based on the above calculations, the equation of the line is:
y = -0.0015x + 213
(b) getting the boiling point at altitude = 2100 ft:
Now, in order to calculate the boiling point at altitude 2100, we will substitute in the equation of the line as follows:
y = -0.0015(2100) + 213 = 209.85 degrees Fahrenheit

A = πr² = π(8²) ≈ 201.06 square inches
C = 2πr = 2π(8) ≈ 50.27 inches
Rounding to the nearest hundredth:
A ≈ 201.06 square inches
C ≈ 50.27 inches
Therefore, the area is approximately 201.06 square inches and the circumference is approximately 50.27 inches.
A circle with a diameter of 20 meters has a radius of 10 meters. The area and circumference are given by:
A = πr² = π(10²) ≈ 314.16 square meters
C = 2πr = 2π(10) ≈ 62.83 meters
Rounding to the nearest hundredth:
A ≈ 314.16 square meters
C ≈ 62.83 meters
Therefore, the area is approximately 314.16 square meters and the circumference is approximately 62.83 meters.
Using these relationships, find the measures of some of the angles:
a) mJKP = mJKN (by vertical angles) and mJKP + mPKL = 90° (by complementary angles), so mJKN + mPKL = 90°.
b) mJKN = mJKP (by vertical angles) and mJKN + mKNM = 90° (by complementary angles), so mJKP + mKNM = 90°.
c) mJLK = mMPL (by alternate interior angles) and mMPL = 63°, so mJLK = 63°.
d) mKNM = 90° - mJKN (by complementary angles). We cannot determine the measure of mJKN.
e) mJLK = mMPL (by alternate interior angles) and mJLR = mJLP (by vertical angles), so:
mJLK + mKLP + mPLJ + mJLP = 360° (by the sum of angles in a quadrilateral)
63° + 90° + mPLJ + mJLP = 360°
mPLJ + mJLP = 207°
f) mJLR = mJLP (by vertical angles) and mKPL = 90°, so:
mJLR + mJLP + mKPL = 180° (by the angles in a triangle)
mJLR + mJLP + 90° = 180°

What is the distance between the points (7,5) (4,9)
The Distance will be 5.
The distance between two points is the length of the line segment connecting the two points on the plane. The formula for finding the distance between two points is usually d=√((x2 – x1)² + (y2 – y1)²). This formula is used to find the distance between any two points on the coordinate or x-y plane.
Let point (7,5) be A and point (4,9) be B
Distance formula =
Ab = √(x1- x2) ² + (y1 -y2) ²
Then Distance AB will be
Ab = √(7-4) ² + (5 -9) ²

The points \((7,5)\) \((4,9)\) are separated by a distance of \(5\) units.
The distance between the two points is given by the length of the segment between them.
The Distance Formula is a helpful tool for figuring out how far apart two points are when they are arbitrarily represented on a coordinate plane as points A\((x_{1},y_{1})\) and B\((x_{2},y_{2})\).
The Pythagorean Theorem is essentially the source of the Distance Formula. Calculating the right triangle's hypotenuse's length is the fundamental purpose of the distance formula.
Use the distance formula to get the distance between two places.
\(d = \sqrt{ (x_{2} - x_{1})^{2} +(y_{2} - y_{1})^{2} }\)

Brett and Andy applied for the same credit card from the same bank. Brett was given a card with an APR of 12.6%. What was his monthly percentage rate? Andy was given a card with an APR of 16.2% what was his monthly percentage rate? if each of them had an average daily balance of $7,980, and had to pay a finance charge, how much more would. Andy pay than Brett?
Andy would pay $23.94 more in finance charges compared to Brett, given their respective APRs, average daily balances, and monthly percentage rates.
To calculate the monthly percentage rate (MPR) from the given annual percentage rate (APR), we divide the APR by 12.
For Brett:
APR = 12.6%
MPR = 12.6% / 12 = 1.05%
For Andy:
APR = 16.2%
MPR = 16.2% / 12 = 1.35%
Next, we can calculate the finance charge for each individual using the formula: finance charge = average daily balance * MPR.
For Brett:
Finance charge = $7,980 * 1.05% = $83.79
For Andy:
Finance charge = $7,980 * 1.35% = $107.73
To find the difference in the finance charges between Andy and Brett, we subtract Brett's finance charge from Andy's finance charge:
Difference = $107.73 - $83.79 = $23.94

Answer: 523.3cm^3
Step By Step Explanation:-The volume of a sphere can be calculated using the formula:
V = (4/3) * π * r^3
where r is the radius of the sphere. The diameter of the sphere is 10 cm, so the radius is half of that, or 5 cm.
Substituting the radius into the formula, we get:
V = (4/3) * π * (5 cm)^3
= (4/3) * π * 125 cm^3
= approximately 523.6 cm^3
So, the closest measurement to the volume of the sphere in cubic centimeters is approximately 523.3 cm^3.
