solve the inequality square root of c plus 9 end root minus square root of c greater than square root of 3. show all work, including testing and verifying your solution set. full credit will not be given if you do not include this in your work.
Our solution set is correct because it contains valid solutions.
We want to eliminate the inequality:
√c + 9 - √c > √3
First, we simplify the inequality's left side:
9 - √c > √3
Following that, we square both sides of the inequality:
81 - 2√c + c > 3
Now we simplify the inequality's right side:
c + 78 > 3
Finally, take 78 off both sides of the inequality:
c > -75
This gives us the following solution set:
c ∈ (-∞, -75) U (-75, ∞)
We test a value from each interval to validate our solution set:
Let's go with c = -100, which is in the range (-, -75). Putting it into context with the original inequality:
√(-100) + 9 - √(-100) > √3
Because the square root of a negative number is not defined, this choice of c is invalid.
Let us choose c = 0, which is in the range (-75,). Putting it into context with the original inequality:
√0 + 9 - √0 > √3
Because 9 > 3, this choice of c is a valid solution.
We can conclude that our solution set is correct because it contains valid solutions.

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
= (-1)² + 3/ (-1)²
= 1 + 3
F(2) = 4

Which measure best describes the typical route time?
mean
spread
median
weighted mean
none of the above
The measure best describes the typical route time is, Median. So option C is correct.
What is the median?The middle number or piece of data in a collection is known as the median. Three alternative metrics are employed in mathematics to determine the average value for a given group of integers. They are the mode, median, and mean. The measures of central tendency are this trio of measurements.
Median = {(n+1)/2}th term (for odd)
Median = [(n/2)th term + {(n/2)+1}th term]/2 (for even)
The median is the middle value in a set of data, and is often used to describe the typical or central value in a dataset. Unlike the mean, which can be affected by extreme values, the median is not sensitive to outliers and provides a better representation of the typical value in the dataset.
For example, if the bus route times are listed in a frequency table, the median can be found by ordering the values and finding the middle value (or the average of the two middle values, if the number of observations is even).
In the context of driving a school bus, the median route time would give the most accurate representation of the typical time it takes to complete the daily route, and would provide a better indicator of the bus driver's performance than the mean or any other measures of central tendency.

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.

He puts twice as much in the lower-yielding account
because it is less risky. His annual interest is $7612
dollars. How much did he invest at each rate?
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%]

From equation 1
x= 30 - y
Substitute 30-y for x in equation 2
8(30-y) + 4y= 220
240 - 8y + 4y= 220
240-4y= 220
-4y= 220-240
-4y= -20
y= 20/4
y= 5
Substitute 5 for y in equation 1
x + y= 30
x + 5= 30
x= 30-5
x= 25

Define the term drainage density
Drainage density is a measure of the frequency and spacing of stream channels within a drainage basin, expressed as the ratio of the total length of streams within a given area to the total area of the drainage basin.
What is the function of Drainage density?Drainage density is used to quantify the efficiency of the drainage system in carrying water away from the land surface and helps in understanding the hydrological and geomorphological processes that shape the landscape.
Therefore, a measure of the frequency and spacing of stream channels within a drainage basin, expressed as the ratio of the total length of streams within a given area to the total area of the drainage basin is drainage density.

The distance, s (in feet), traveled by a car moving in a straight line is given by the function, st=t2+t where t is measured in seconds. Find the average velocity for the time period from t = 1 to t = 4. Hint: Average velocity is displacement divided by time interval of the displacement.
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
s(4) = (4)^2 + 4
s(4) = 16 + 4
s(4) = 20
Let at t = 1, it is t(1) and at t = 4 it is t(2)
Displacement of car between t(1) and t(4) = s(2) - s(1)
Displacement of car between t(1) and t(4) = 20 - 2
Displacement of car between t(1) and t(4) = 18 feet
Time travel between t(1) and t(4) = 4 - 1
Time travel between t(1) and t(4) = 3
Now,
Average velocity = Displacement of car between t(1) and t(4)/Time travel between t(1) and t(4)
Average velocity = 18/3
Average velocity = 6 feet/s
