Find the length of side of square ABCD when diagonal is √ cm long. Also find the perimeter and area of the square
The length of each side of the square is 16 cm, the perimeter is 64 cm, and the area is 256 cm^2.
Let's solve the problem step by step. We have a square ABCD, and we need to find the length of its sides when the diagonal is 16√2 cm long.
In a square, the diagonal forms a right triangle with the sides. The sides of a square are equal in length, so let's assume the length of one side of the square is 'x' cm.
Using the Pythagorean theorem, we can find the relationship between the side length and the diagonal:
x^2 + x^2 = (16√2)^2
2x^2 = 512
Dividing both sides by 2, we have:
x^2 = 256
Taking the square root of both sides:
x = √256
x = 16 cm
So, the length of each side of the square is 16 cm.
To find the perimeter of the square, we simply multiply the length of one side by 4 since all sides are equal:
Perimeter = 4 * 16 cm = 64 cm
To find the area of the square, we square the length of one side:
Area = (16 cm)^2 = 256 cm^2

What is the meaning of "\(F=\left \{ (x,y):\varphi (x,y,p) \right \}\)"?
The expression "F = {(x, y) : φ(x, y, p)}" represents a set of ordered pairs (x, y) that satisfy a condition defined by the function φ. The interpretation and nature of the set F depend on the specific function φ and the parameter p, which determine the relationship between the variables x, y, and p.
The expression "F = {(x, y) : φ(x, y, p)}" represents a set F consisting of ordered pairs (x, y) that satisfy a particular condition defined by the function φ, which takes the variables x, y, and p as inputs.
To fully understand the meaning of F, we need to delve into the function φ and its relationship with the variables x, y, and p. The function φ could represent a wide range of mathematical relationships or conditions that determine the inclusion of certain pairs (x, y) in the set F.
For instance, let's consider a specific example where vraphi(x, y, p) is defined φ(x, y, p) = \(x^2 + y^2 - p^2.\)In this case, F = {(x, y) : \(x^2 + y^2 - p^2\)= 0} represents a set of ordered pairs (x, y) that satisfy the equation \(x^2 + y^2 - p^2 = 0.\) This equation represents a circle with radius p centered at the origin (0, 0). Consequently, F corresponds to all the points lying on the circumference of this circle.
It is important to note that the specific meaning and implications of F heavily rely on the nature of the function φ and the parameter p. Different functions and parameters will yield distinct sets F with their own unique characteristics and interpretations.

Sara, Emma, and Anna are buying party decorations. Sara is paying 1/2 of the total cost. Emma contributes 1/3 of the money, and Anna contributes 1/4. When they arrive at the checkout line, they realize that there is sales tax on the purchase. Luckily, they have exactly the right amount of money to pay for the decorations. ANSWER BOTH TY
Question 1
Which fraction represents the amount of tax added to the cost of the items?
Responses
A. 1/12
B. 1/4
C. 1/3
D. 1/6
Question 2
If the cost of all the items before tax is added is $24.00, how much tax is added?
Responses
A $2.40
B $2.00
C $3.00
D $.80
Answer:
We can start by finding the combined fraction of the amount of money contributed by the three friends:
Sara pays 1/2 of the total cost, which is equivalent to 6/12.
Emma contributes 1/3 of the money, which is equivalent to 4/12.
Anna contributes 1/4 of the money, which is equivalent to 3/12.
Adding these fractions gives us:
6/12 + 4/12 + 3/12 = 13/12
This means that the total cost of the decorations plus tax is 13/12 of the original cost. Since they have exactly the right amount of money to pay for the decorations, we can infer that the tax is equal to 1/12 of the original cost. Therefore, the answer is A. 1/12.
If the cost of all the items before tax is $24.00, then we can calculate the amount of tax added by multiplying the cost by the fraction that represents the tax. From the previous question, we know that the fraction representing the tax is 1/12. Multiplying $24.00 by 1/12 gives:
$24.00 x 1/12 = $2.00
Therefore, the answer is B. $2.00.

There are 5 red marbles, 8 blue marbles, and 12 green marbles in a bag.
What is the theoretical probability of randomly drawing a red marble?
25%
62.5%
20%
41.7%
Answer:
20%
Step-by-step explanation:
The theoretical probability of drawing a red marble can be found by dividing the number of red marbles by the total number of marbles in the bag:
P(red) = number of red marbles / total number of marbles
P(red) = 5 / (5 + 8 + 12)
P(red) = 5 / 25
P(red) = 0.2
So the theoretical probability of randomly drawing a red marble is 20%, which corresponds to option (C).

An investor wants to save money to purchase real estate. She buys an annuity with yearly payments that earn 5.3% interest compounded annually payments will be made at the end of each year find the total value of the annuity in 16 years if each yearly payment is 693.
The total value of the annuity in 16 years, with yearly payments of $693 and an interest rate of 5.3% compounded annually, is approximately $12,739.62.
To calculate the total value of the annuity in 16 years, we can use the formula for the future value of an annuity:
FV = P * ((1 + r)^n - 1) / r
Where:
FV is the future value of the annuity,
P is the yearly payment,
r is the interest rate per compounding period, and
n is the number of compounding periods.
In this case, the yearly payment (P) is $693, the interest rate (r) is 5.3% or 0.053, and the number of compounding periods (n) is 16.
Let's substitute these values into the formula and calculate the total value of the annuity:
FV = 693 * ((1 + 0.053)^16 - 1) / 0.053
FV = 693 * (1.053^16 - 1) / 0.053
Using a calculator, we can evaluate the expression inside the parentheses:
1.053^16 ≈ 1.9738
Substituting this value back into the formula:
FV = 693 * (1.9738 - 1) / 0.053
FV = 693 * 0.9738 / 0.053
FV ≈ 12739.62
Therefore, the total value of the annuity in 16 years, with yearly payments of $693 and an interest rate of 5.3% compounded annually, is approximately $12,739.62.

Answer:3/4
Step-by-step explanation:
3/4
Answer:
3/4
Step-by-step explanation:
We need to list out the factors of each number, find the greatest common factor, and then divide both sides of the fraction by this number to find the fraction's most simplified form. So, let's list the factors of each number:
93: 1, 3, 31, 93
124: 1, 2, 4, 31, 62, 124
Notice the number that I put in bold - 31. This is a factor that both 93 and 124 share that we can use to simplify it. So, let's divide the numerator and the denominator of the fraction by 31.
93 ÷ 31 = 3, and 124 ÷ 31 = 4. So, we are left with 3/4, which cannot be simplified any further.

A 25-year, $1,000 par value bond has an 8.5% annual coupon. The bond currently sells for $875. If the yield to maturity remains at its current rate, what will the price be 5 years from now?
Given the current yield to maturity of the bond, the price of the bond five years for now is $883.10.
What is the price of the bond five years from now?The first step is to determine the yield to maturity of the bond. The yield to maturity is the return on the bond if the bond is held to matuity.
Yield to matuity can be determined using a financial calculator:
Cash flow in year 0 = -875
Cash flow each year from year 1 to 25 = 85
Cash flow in year 25 = $1000
Yield to matuity = 9.86%
Future price of the bond: (coupon x future price factor) + [FV / (1 + YTM)^n)]
Future price factor = [1 - (1/YTM)^n] / YTM
= [1 - 1/0.0986^20] 0.0986 = 8.595555

ducational Television In a random sample of people, said that they watched educational television. Find the confidence interval of the true proportion of people who watched educational television. Round the answers to at least three decimal places.
Complete Question
Educational Television In a random sample of 200 people, 159 said that they watched educational television. Find the 90% confidence interval of the true proportion of people who watched educational television. Round the answers to at least three decimal places.
Answer:
The 90% confidence interval is \(0.748 < p < 0.842\)
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The number of people that watched the educational television is \(k = 159\)
Generally the sample proportion is mathematically represented as
\(\^ p = \frac{159}{200}\)
=> \(\^ p = 0.795\)
From the question we are told the confidence level is 90% , hence the level of significance is
\(\alpha = (100 - 90) \%\)
=> \(\alpha = 0.10\)
Generally from the normal distribution table the critical value of \(\frac{\alpha }{2}\) is
\(Z_{\frac{\alpha }{2} } = 1.645\)
Generally the margin of error is mathematically represented as
\(E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } \)
=> \(E = 1.645 * \sqrt{\frac{0.795 (1- 0.795)}{200} } \)
=> \(E = 0.04696 \)
Generally 95% confidence interval is mathematically represented as
\(\^ p -E < p < \^ p +E\)
=> \(0.795 -0.04696 < p < 0.795 + 0.04696\)
=> \(0.748 < p < 0.842\)

Given that Ciera is creating a logo on the figure grid, let's find the area of inner square to the area of the outter square.
• Area of inner square:
Let's first find the length of one side of the inner square.
Take two end points:
(x1, y1) ==> (0, 4)
(x2, y2) ==> (4, 10)
Apply the distance formula:
\(\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ d=\sqrt{(4-0)^2+(10-4)^2} \\ \\ d=\sqrt{4^2+6^2} \\ \\ d=\sqrt{16+36} \\ \\ d=\sqrt{52} \\ \\ d=7.2\text{ units} \end{gathered}\)The length of one side of the inner square is 7.2 units.
To find the area, apply the formula:
\(A=l^2\)Where:
l = 7.2 units
We have:
\(Area=7.2^2=52\text{ square units}\)Therefore, the area of the inner square is 52 square units.
• Area of the outer square:
From the graph, the length of one side of the outer square is:
L = 10 units.
The area will be:
\(A=10^2=100\text{ square units}\)The area of the outer square is 100 square units.
• Ratio of area of inner square to area of outer square:
For the ratio, we have:
\(\begin{gathered} Ratio=Area\text{ of inner square : Area of outer square} \\ \\ Ratio=52:100 \\ \\ Ratio=13:25 \end{gathered}\)Therefore, the ratio of the area inner square to the area of the outer square is 13 : 25
ANSWER:
The area of the inner square is: 52 square units
The area of the outer square is: 100 square units
The ratio of the area of the inner square to the area of the outer square is: 13 : 25
1 : The area of the inner square is 52 square units. The area of the outer square is 100 square units.
2: The ratio of the area of the inner square to the area of the outer square is 0.52
Step-by-step explanation:
In circle O, secants ADB and AEC are drawn from external point A
such that points D, B, E, and C are on circle O. If AD = 8, AE = 6,
and EC is 12 more than BD, the length of BD is
(1) 6
(2) 22
(3) 36
(4) 48
The length of BD is 22.
In the given scenario, let's consider the following information.
AD = 8
AE = 6
EC is 12 more than BD.
To find the length of BD, we can utilize the Intercepted Arcs Theorem, which states that when two secants intersect outside a circle, the measure of an intercepted arc formed by those secants is equal to half the difference of the measures of the intercepted angles.
From the given information, we know that AD = 8 and AE = 6.
Since these are the lengths of the secants, we can use them to calculate the intercepted arcs.
First, let's find the intercepted arc corresponding to AD:
Intercepted Arc ADB = 2 \(\times\) AD = 2 \(\times\) 8 = 16
Similarly, we can find the intercepted arc corresponding to AE:
Intercepted Arc AEC = 2 \(\times\) AE = 2 \(\times\) 6 = 12
Now, we know that EC is 12 more than BD.
Let's assume the length of BD as x.
BD + 12 = EC
Now, let's consider the intercepted arcs theorem:
Intercepted Arc ADB - Intercepted Arc AEC = Intercepted Angle B - Intercepted Angle C
16 - 12 = Angle B - Angle C
4 = Angle B - Angle C.
Since Angle B and Angle C are vertical angles, they are congruent:
Angle B = Angle C.
Therefore, we can say:
4 = Angle B - Angle B

What are the exact solutions of x2 − 3x − 1 = 0 using x equals negative b plus or minus the square root of the quantity b squared minus 4 times a times c all over 2 times a? (1 point) x = the quantity of 3 plus or minus the square root of 5 all over 2 x = the quantity of negative 3 plus or minus the square root of 5 all over 2 x = the quantity of 3 plus or minus the square root of 13 all over 2 x = the quantity of negative 3 plus or minus the square root of 13 all over 2
Answer:
Step-by-step explanation:
x² - 3x - 1 = 0
a = 1, b = -3, c = -1
x₁ = (3 + sqrt(-3² - 4(1(-1))))/(2(1))
x₁ = (3 + sqrt(9 + 4))/2
x₁ = (3 + sqrt(13))/2
x₁ = 3.302...
x₂ = (3 - sqrt(-3² - 4(1(-1))))/(2(1))
x₂ = (3 - sqrt(9 + 4))/2
x₂ = (3 - sqrt(13))/2
x₂ = -0.302...
