Find the slope of the tangent line mtan = f'(a)and b. find the equation of the tangent line to f at x = a f(x)=√x+8, a = 1
The slope of the tangent line mtan = f'(a) is equal to the derivative of the function f(x) at the point a. Since f(x) = √x + 8, we can find the derivative using the power rule, which gives f'(x) = 1 / (2√x + 8). Evaluating this at a = 1, we get f'(1) = 1 / (2√1 + 8) = 1 / 6. Therefore, the slope of the tangent line is 1/6.
To find the equation of the tangent line to f at x = a, we can use the point-slope form of the equation of a line, which is y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope of the line. Since we know that the slope of the tangent line is 1/6 and the point on the line is (1, 3), we can substitute these values into the equation to get y - 3 = (1/6)(x - 1). Simplifying this equation gives us y = (1/6)x + (17/6). Therefore, the equation of the tangent line to f at x = 1 is y = (1/6)x + (17/6).

(L2) A circle that contains a polygon so that it passes through each vertex of the polygon is a(n) _____ circle.
(L2) An inscribed circle is one that encompasses a polygon so that it passes by each of the polygon's vertices.
A circumcircle, not an inscribed circle, is a circle that encircles a polygon at each vertex. A circle that is enclosed within a polygon and intersects each side of the polygon exactly once is said to be inscribed. A circumcircle, on the other hand, is a circle that goes through every vertex of the polygon, with its center located at the point where the perpendicular bisectors of the polygon's sides converge. The greatest circle that can be drawn within a polygon is the circumcircle, while the largest circle that can be drawn inside a triangle is the inscribed circle.

For the function -3x^2+12
find the interval over which the function is increasing.
Answer:
The given function is:
f(x) = -3x^2 + 12
To find the interval over which the function is increasing, we need to find the critical points of the function.
f'(x) = -6x
The critical point is where f'(x) = 0
-6x = 0
x = 0
Now, we need to check the sign of f'(x) on either side of the critical point to determine whether the function is increasing or decreasing.
If x < 0, then f'(x) < 0, so the function is decreasing.
If x > 0, then f'(x) > 0, so the function is increasing.
Therefore, the interval over which the function is increasing is:
(0, infinity)

The height, h, in feet of a ball above the ground is given by h = −16t2 + 64t + 80, where t is the time in seconds. How long does it take the ball to hit the ground?
Answer:
t = 5 seconds
Step-by-step explanation:
It is given that, the height h, in feet of a ball above the ground is given by :
\(h=-16t^2+64t+80\)
Where t is in seconds
We need to find how long does it take the ball to hit the ground? When it hits the ground, its height will be equal to 0. So,
\(-16t^2+64t+80=0\\\\t=\dfrac{-64\pm \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=\dfrac{-64+ \sqrt{(64)^2-4\times (-16)(80)} }{2\times -16},\dfrac{-64-\sqrt{(64)^2-4\times (-16)(80)} }{2\times -16}\\\\t=-1\ s\ \text{and}\ t=5\ s\)
Neglecting negative time.
It means ball will take 5 seconds to hit the ground.

The radius of the ball, to the nearest hundredth, is approximately 10.63 cm.
To find the radius of the spherical ball, we'll use the formula for the surface area of a sphere, which is given by:
Surface Area = 4πr²
Given that the surface area of the ball is 452 cm², we can set up the equation:
452 = 4πr²
Dividing both sides of the equation by 4π, we get:
113 = r²
Taking the square root of both sides, we find:
r ≈ √113
Evaluating √113 to the nearest hundredth, we have:
r ≈ 10.63 cm
Therefore, the radius of the ball, to the nearest hundredth, is approximately 10.63 cm.

in evaluating the results of a compliance test that utilizes statistical sampling, what course of action could the auditor take if the computed upper deviation rate (sample deviation rate projected to the population and adjusted for sampling risk) exceeds the tolerable deviation rate?
If the computed upper deviation rate (sample deviation rate projected to the population and adjusted for sampling risk) exceeds the tolerable deviation rate during a compliance test that utilizes statistical sampling,
it means that the test results indicate, the population of items being tested is not in compliance with the standards or regulations.
There are several actions that the auditor could take in this situation, depending on the specific circumstances of the test and the nature of the non-compliance. These are:
Conduct additional testing: The auditor may decide to conduct additional testing to confirm the results of the initial test and to identify the specific items or areas that are out of compliance.Address the non-compliance: The organization or individual being tested should address the non-compliance by implementing corrective actions to bring the items into compliance with the standards or regulations.Notify the relevant authorities: Depending on the nature of the non-compliance, the debtor may be required to notify relevant authorities such as regulatory bodies or government agencies.Review and improve internal processes: The debtor should review and improve internal processes to ensure that they are in compliance with standards and regulations in the future.Investigate and report: The debtor should investigate the cause of the non-compliance and report the findings to the relevant authorities.Note that: the specific course of action will depend on the nature of the non-com pliance and the regulations or standards that apply. It is recommended that the debtor consults with legal or regulatory experts to ensure that they are taking the appropriate actions to address the non-compliance.

what type of rank 8 spell is granted to death students at level 58?
The Death students in Wizard101 are granted with the Scarecrow spell as their rank 8 spell at level 58.What is Scarecrow? Scarecrow is a rank 8 spell that is only granted to Death wizards. This spell deals 530-610 damage to all enemies and gives the player half of that damage back as health.
It also costs 7 pips to cast, making it a powerful spell that can help the wizard defeat multiple enemies at once. Scarecrow's damage output, as well as its healing effects, make it an excellent choice for Death wizards who are soloing the game or facing multiple enemies in a battle. Its main weakness is its high pip cost, which can make it difficult to cast in the early stages of a battle when the wizard may not have accumulated enough pips yet to cast it. Nonetheless, Scarecrow is a powerful and useful spell that can help Death wizards survive tough battles.The Scarecrow spell is not only exclusive to Death students but also a prized possession of some of the toughest bosses and enemies in the game. For example, Malistaire the Undying, one of the most difficult bosses in the game, uses Scarecrow as one of his main spells, making it an even more coveted and powerful spell for Death wizards to have in their arsenal.
