Answer:
The equation of a circle can be represented in the form (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center of the circle and r is the radius.
A diameter of a circle is a straight line passing through the center of the circle and has endpoints on the circle.
Given that the equation of the diameter of a circle is x+y-14=0 and 2x-y-4=0, we can find the center of the circle by solving for the intersection of these two lines.
We can find the intersection point of these lines by solving the system of equations using the substitution method:
x+y-14=0 and 2x-y-4=0
x = 14/3, y = 10/3
So the center of the circle is (14/3, 10/3)
Since we know that the point (3,4) lies on the circle, we can use the distance formula to find the radius of the circle.
r = sqrt((x-h)^2 + (y-k)^2)
r = sqrt((3-(14/3))^2 + (4-(10/3))^2) = sqrt(5)
Therefore, the equation of the circle is (x-14/3)^2 + (y-10/3)^2 = 5^2
or (x-14/3)^2 + (y-10/3)^2 = 25
So, the equation of the circle passing through point (3,4) and having equation of its diameter x+y-14=0 and 2x-y-4=0 is (x-14/3)^2 + (y-10/3)^2 = 25

The value for the function f(x) = z² + 3/z² for f(2) is 4.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range.
Given:
f(x) = z² + 3/z²
Also we have f(1)= 2 then
f(1) = z² + 3/z²
2 = z² + 3/z²
2z² = [tex]z^4[/tex] + 3
-3 = [tex]z^4[/tex] - 2z²
-3 = z²(z²-2)
So, z²= -3 or z²-2 = -3
z= ±√3i or z =i
Now, F(2) we get
F(2) = z² + 3/z²

The average velocity for the time period from t = 1 to t = 4 is 6 feet/s.
The distance driven in a car is shown by
s(t) = t^2 + t
The distance driven in a car at t = 1
s(1) = (1)^2 + 1
s(1) = 1 + 1
s(1) = 2
The distance driven in a car at t = 4

If x is normally distributed with mean 140 and standard deviation 20, find P(140 < x < 150) (round off to fourth decimal place).
P(140 < x < 150) is 0.1915 when x is normally distributed with mean 140 and standard deviation 20.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value
μ = mean = 140
σ = standard deviation = 20
z-score(x = 140) = (140 - 140) / 20
z-score(x = 140) = 0
z-score(x = 150) =(150 - 140) / 20
z-score(x = 150) = 0.5
Find the probability that corresponds to the z-score in the z-table. (see attached images)
z-score = 0 probability = 0.5000
z-score = 0.5 probability = 0.6915
This means that there's a probability of 0.500 and 0.6915 that the value of x is less than 140 and 150, respectively.
P(140 < x < 150) = 0.6915 - 0.5000 = 0.1915
Therefore, the probability that the value of x is between 140 and 150 is 0.1915.

It is only appropriate and possible to calculate the variance and standard deviation as measures of variability for variables measured using a(n) scale of measurement. O ordinal O ratio O interval or ratio O ordinal or nominal
Variance and standard deviation are measures of variability that are appropriate and possible to calculate for variables measured on an interval or ratio scale of measurement.
Interval scales have a true zero point, meaning that a difference of zero on the scale represents a lack of the characteristic being measured (e.g. temperature measured in degrees Celsius). Ratio scales are similar to interval scales, but also have a meaningful zero point, meaning that a value of zero on the scale represents a complete absence of the characteristic being measured (e.g. height measured in meters).
Variance and standard deviation can be calculated for interval and ratio variables because these scales provide meaningful differences and ratios between values. The calculation of variance involves finding the average squared difference between each value and the mean of the values, while standard deviation is the square root of the variance. Both variance and standard deviation provide information about how spread out the values of a variable are and are useful in statistical analysis.
On the other hand, nominal and ordinal scales only provide categories or rank order for values, without any meaningful differences or ratios between values. As such, it is not appropriate or possible to calculate variance or standard deviation for variables measured on nominal or ordinal scales.

Simple Interest Consider making an investment of $100 (the principal) at a 5% yearly rate for a year. Simple interest is calculated as follows: $100 multiplied by.05 percent per year for a total of $5 after a year.
What is the simple interest per year?Let x represent the sum of money invested at a simple interest rate of 6%. Let y represent the sum of money invested at a simple interest rate of 10%.
Decimalize the interest rates as follows: 6% equals 0.06 and 10% equals 0.10. The interest earned on the first account is equal to 0.06 times the interest rate multiplied by the amount invested.
Similar to the first account, the second account's interest earnings are calculated as the interest rate times the amount invested, or 0.10*y.
Now that we have the data from the problem, we need to model the scenario with two equations. Because it is less hazardous, the man invests twice as much in the lower-yielding account. Otherwise put,
[the investment amount at 6%] = [2] * [the investment amount at 10%]
We can represent this relationship in algebra as
x=2y
Therefore, the amount the man earns in interest is $4,180.

Let w = f(x^2 − y^2, y^2 − x^2), where f is a differentiable two-variable function. Calculate y.∂w / ∂x + x. ∂w / ∂y
The value of y. (∂w / ∂x) + x. (∂w / ∂y) is,
⇒ - 4xy f ' (x² - y², y² - x²)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The two-variable function is,
⇒ w = f (x² - y², y² - x²)
Now, We can differentiate the function as;
⇒ (∂w / ∂x) = f ' (x² - y², y² - x²) × (2x , - 2x)
⇒ (∂w / ∂y) = f ' (x² - y², y² - x²) × (- 2y , 2y)
Thus, The value of y. (∂w / ∂x) + x. (∂w / ∂y) is,
⇒ y. (∂w / ∂x) + x. (∂w / ∂y)
⇒ y × f ' (x² - y², y² - x²) × (2x , - 2x) + x × f ' (x² - y², y² - x²) × (- 2y , 2y)
⇒ - 2xy × f ' (x² - y², y² - x²) - 2xy × f ' (x² - y², y² - x²)
⇒ - 4xy f ' (x² - y², y² - x²)
