Find the derivative using the definition of derivatives
The derivative of the given expression is as follows = [tex]\frac{1}{2 \sqrt{x_0}}[/tex]
definition of derivatives:The derivative is the rate of change in a function without respect to a variable in mathematics. Derivatives are essential for solving calculus as well as differential equations problems.
What is a derivative and what are the many types?Options, forwards, futures, and swaps are the four primary types of derivative contracts. Options represent derivative contracts that provide the buyer the right to buy or sell the underlying asset at a predetermined price during a specific time period. The purchaser is not required to execute the option.
According to the given data:Let f:(0,∞)→R;
f(x)=√x, and x₀∈(0,∞) be an accumulation point of (0,∞).
We must find f′ such that for all x₀, f′(x₀) defined as:
limx→x₀(f(x)−f(x₀))/(x−x₀) exists.
Now,
x−x₀=(√x−√(x₀))(√x +√(x₀)).
Then:
[tex]\lim _{x \rightarrow x_0} \frac{f(x)-f\left(x_0\right)}{x-x_0}[/tex] = [tex]\lim _{x \rightarrow x_0} \frac{\sqrt{x}-\sqrt{x_0}}{\left(\sqrt{x}-\sqrt{x_0}\right)\left(\sqrt{x}+\sqrt{x_0}\right)}[/tex]
= [tex]\lim _{x \rightarrow x_0} \frac{1}{\sqrt{x}+\sqrt{x_0}}[/tex]
= [tex]\frac{1}{2 \sqrt{x_0}}[/tex]
The derivative of the given expression is as follows = [tex]\frac{1}{2 \sqrt{x_0}}[/tex]

Volume, or how much liquid a container can hold, is measured in quarts in both British Imperial and US customary measurements. A quart is equal to two pints or one-fourth of a gallon.
One standard imperial quart, which is equal to two imperial pints or one-fourth of an imperial gallon, is used in the British imperial system for both dry and liquid measurements. The US Customary system has two units called quarts, one for measuring liquids and the other, a little bigger, for measuring dry goods.

I have been stuck on this for the past 10 mins PLS HELP
Answer:
55°
Step-by-step explanation:
m∠D = m∠A + m∠B since for a triangle, the exterior angle = sum of interior angles
We can rewrite this as
m∠A + m∠B = m∠D
Given m∠A = (2x)° , m∠B = (3x + 41)° and m∠D = 124° and substituting in the above equation,
2x + (x + 41.5) = 124
2x + x + 41.5 = 124
3x + 41.5 = 124
3x = 124 - 41.5 = 82.5
x = 82.5/3 = 27.5
But m∠A = (2x) = 2 x 27.5 = 55°

A research group surveyed 250 students. The students were asked how often they go to the movies and whether they prefer comedies or dramas
A percentage can be defined as any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.
The percentage of the students who go to the movies three times a month or more is given by:
Total students = 30 + 55 = 85 students.
Percentage = 85/250 × 100
Percentage = 0.34 × 100

You are building an arc entrance over a roadway. The road under
the arc is 20 feet wide with a 6-foot sidewalk on both sides of
the road. Write an equation to accomplish this task.
The equation of the parabolic arc that accomplishes this task is:
y = (-k/256)(x - 16)² + k.
In which k is the maximum height of the arc.
What is the equation of a parabola given it’s vertex?The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
For this problem, the arc has these following characteristics:
Parabolic.Concave down.The peak is at half the road.The road under the arc is 20 feet wide with a 6-foot sidewalk on both sides of the road, hence it's total length is of 20 + 2 x 6 = 32 feet, and the peak of the arc will be at h = 16.
Hence:
y = a(x - 16)² + k.
The height is of 0 at x = 0 and x = 32, hence:
0 = 256a + k.
a = -k/256
y = (-k/256)(x - 16)² + k.
In which k is the maximum height of the arc.

What is the value of k?
Answer:
k = 2
Step-by-step explanation:
in such a case we look immediately at the cases y = 0 and/or x = 0
only if that does not lead us to an answer, do we need to look further.
y = 0, that means according to the graph that x = -2.
so, we have
0 = |x + k| = |-2 + k|
that can only be the case, if k = 2

Kaylee owns a food truck that sells tacos and burritos. She only has enough supplies to make 120 tacos or burritos. She sells each taco for $3 and each burrito for $6. Kaylee must sell at least $480 worth of tacos and burritos each day. If xx represents the number of tacos sold and yy represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
The system of inequalities is:
x + y ≤ 120
x*3 + y*6 ≥ 480
And one possible solution to it is x = 20 and y = 80.
How to find the system of inequalities?
First, we need to define two variables, we will be using:
x = number of tacos.y = number of burritos.We know that she can make at most 120 units, then:
x + y ≤ 120
And she wants to win at leastt $480, then:
x*3 + y*6 ≥ 480
So our system of inequalities is:
x + y ≤ 120
x*3 + y*6 ≥ 480
And the graph can be seen in the image below, the solution set of the system is given by the region where both shaded areas intersect.
There we can see that one possible solution is x = 20 and y = 80, in that case the total number of items made is:
20 + 80 = 100, which is less than 120
And the income is:
20*3 + 80*6 = 540.

At a particular restaurant, each mini hotdog has 90 calories and each pizza roll has 50 calories. A combination meal with pizza rolls and mini hotdogs is shown to have 860 total calories and 6 more pizza rolls than mini hotdogs. Write a system of equations that could be used to determine the number of mini hotdogs in the combination meal and the number of pizza rolls in the combination meal. Define the variables that you use to write the system.
The system of equations we need to solve is:
x*90 + y*50 = 860
y = x + 6
Solving that we will see that there are 4 mini hot dogs and 10 pizza rolls.
How to write the system of equations?First, we need to define the variables we will be using, these are:
x = number of mini hotdogs.
y = number of pizza rolls.
We know that the combination has 860 calories in total, so:
x*90 + y*50 = 860
We also know that there are 6 more pizza rolls than mini hotdogs, so:
y = x + 6
Then the system of equations is:
x*90 + y*50 = 860
y = x + 6
Replacing the second equation into the first one, we will get:
x*90 + (x + 6)*50 = 860
Now we can solve this for x.
x*90 + x*50 + 300 = 860
x*140 + 300 = 860
x*140 = 860 - 300
x*140 = 560
x = 560/140 = 4
So there are 4 mini hotdogs, and:
y = x + 6
y = 4 + 6 = 10
There are 10 pizza rolls.

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.Hence, the middle 95% of values is within 2 standard deviations of the mean, with bounds given as follows:

A student states that a triangle can be formed with side lengths 4 in, 5 in, and 8 in. Is the student correct? Why, or why not?
Its formed an obtuse triangle with side lengths 4 in, 5 in, and 8 in.
What is obtuse triangle?
A triangle is said to have an obtuse angle if one of the inner angles is greater than 90 degrees. If one of the angles of an obtuse triangle is greater than 90°, then the total of the other two angles is also less than 90°.Any two of a triangle's angles that are equal in size are said to be in an isosceles triangle. Furthermore, the length of the two sides that are opposite those equal angles is also equal. A triangle is said to be obtuse if one of the angles is between 90 and 180 degrees, while the other two are acute (less than 90 degrees).When given 3 sides of a triangle, the longest side must be less than the sum of the other 2 sides.
8 < 4 + 5 so a triangle can be formed.
