A ball is thrown straight up from a height of 3 ft with a speed of 32 ft/s. Its height above the ground after x seconds is given by the quadratic function y = -16x^2 + 32x + 3. Explain the steps you would use to determine the path of the ball in terms of a transformation of the graph of y = x^2.

Answers

The height above ground (y) as function of time (x) is given as
y = -16x² + 32x + 3

Write the equation in the standard form for a parabola.
y = -16[x² - 2x] + 3
   = -16[(x-1)² - 1] + 3
   = -16(x-1)² + 16 + 3
y = -16(x-1)² + 19
This equation shows that the parabola is downward, has its vertex at (1,19), and has its axis of symmetry at x = 1.
A plot of the graph is shown below.

Transformations of y = x².
The equation for the parabola can be obtained from y = x² in the following steps:
1. Shift right by 1 to obtain y = (x-1)².
2. Dilate by -16 to obtain y = -16(x-1)².
3. Shift up by 19 to obtain y = -16(x-1)² + 19.

Two complementary angles have measures of 15° and (x+5)°. what is the value of x? *

Answers

The equation would look like this: 15 + x + 5 = 90.
Combine like terms to get this: 20 + x = 90.
Subtract 20 from both sides to get this: x = 70.

x = 70
Final answer:

The value of x is 70 degrees. This is obtained by solving the equation formed from the definition of complementary angles (the sum of the angles is 90 degrees).

Explanation:

In mathematics, two angles are said to be complementary if the sum of their measures is 90 degrees. In this case, the two angles in question have measures of 15 degrees and (x+5) degrees. Therefore, we can create an equation by adding the two measures and setting the sum equal to 90.

So, 15 + (x+5) = 90.

Solving for x, we first combine like terms, yielding x + 20 = 90. Then we simply subtract 20 from both sides of the equation to obtain the value for x. So, x = 90 - 20 = 70 degrees.

What is the difference between advanced calculus and real analysis?

Answers

The content of any course depends on where you take it--- even two courses with the title "real analysis" at different schools can cover different material (or the same material, but at different levels of depth).

But yeah, generally speaking, "real analysis" and "advanced calculus" are synonyms. Schools never offer courses with *both* names, and whichever one they do offer, it is probably a class that covers the subject matter of calculus, but in a way that emphasizes the logical structure of the material (in particular, precise definitions and proofs) over just doing calculation.

My impression is that "advanced calculus" is an "older" name for this topic, and that "real analysis" is a somewhat "newer" name for the same topic. At least, most textbooks currently written in this area seem to have titles with "real analysis" in them, and titles including the phrase "advanced calculus" are less common. (There are a number of popular books with "advanced calculus" in the title, but all of the ones I've seen or used are reprints/updates of books originally written decades ago.)

There have been similar shifts in other course names. What is mostly called "complex analysis" now in course titles and textbooks, used to be called "function theory" (sometimes "analytic function theory" or "complex function theory"), or "complex variables". You still see some courses and textbooks with "variables" in the title, but like "advanced calculus", it seems to be on the way out, and not on the way in. The trend seems to be toward "complex analysis."  hope it helps

Final answer:

Advanced calculus covers computational aspects and applications of calculus in multiple dimensions, while real analysis focuses on the theoretical fundamentals, such as rigorous development of the real number system and proof-based examination of limits and continuity.

Explanation:

The difference between advanced calculus and real analysis lies in the focus and depth of the subjects. Advanced calculus, also known as calculus III in some curricula, typically extends the study of calculus to multiple dimensions, covering topics such as partial derivatives, multiple integrals, and vector calculus. It focuses more on the computational aspects and applications of calculus.

Real analysis, on the other hand, delves deeper into the theoretical underpinnings of calculus and analysis. It deals with the rigorous development of the real number system, sequences and series, continuity, differentiation, integration, and convergence. Real analysis puts a strong emphasis on proof and logical reasoning, providing a foundation for the truth and logic behind the mathematics used in calculus.

While both subjects are mathematically advanced, real analysis is considered to be more abstract and is often a stepping stone for further study in pure mathematics. Familiarity with calculus is often a prerequisite before studying real analysis as it lays the groundwork for the more complex theoretical concepts.

Classify the following triangle.Check all that apply.

Answers

Answer:

Obtuse and Isosceles

:) Apex

The triangle in the image can be classified as follows:

The correct options will be

Right [ F] : One of the angles is 90 degrees.

Isosceles [ D]: Two of the sides are equal (the two shorter sides).

We can see from the triangle that two of the angles measure 41 degrees each and the third angle is 98 degrees. The sum of the angles in a triangle is 180 degrees, and since 41 + 41 + 98 = 180, we know that the triangle is valid.

Right triangles can also be isosceles (in fact, there is a specific type of right triangle called a 45-45-90 triangle). So, this triangle qualifies for both classifications.

The triangle cannot be classified as:

Acute [ B]: Acute triangles have all angles less than 90 degrees.

Obtuse [ A]: Obtuse triangles have one angle greater than 90 degrees.

Equilateral [ E]: Equilateral triangles have all three sides equal.

A polynomial function P(x) has a degree n. If n is even is the number of turning points of the graph of p(x) even or odd? What can you say about the number of turning points if n is odd?

Answers

I think the number of turning points if n is even  is odd.
For n = odd it could be odd or even.

The number of turning points if n is odd if A polynomial function P(x) has a degree n, is even.

What is polynomial?

A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.

Given:

A polynomial function P(x) has a degree n,

A turning point is when the derivative's sign changes. A relative maximum or relative minimum might mark a turning point (also known as local minimum and maximum). A turning point is a stationary point if the function is differentiable, however not all stationary points are turning points.

For example, if the degree is 2 then the number of turning points will be 1

The general formula is, the number of turning points = n - 1

Thus, for odd n, the turning point will be even.

Sales fall from 300 per week to 270 per week what’s the percentage change

Answers

Hi there! 

Your question: 

Sales fall from 300 per week to 270 per week what's the percentage change?

My answer:

The formula for calculating percent change is as follows: 

[(y2 - y1)/y1]*100=your percent change 

y2= first value 
y1=second value 

Plug the numbers in: 

[(300-270)/300]*100

[30/300]*100

0.1*100

10 

Therefore, the percent change is 10%

Trevor is swimming laps to raise money for the local food bank. He earns $1.85 per lap and has already swum 23 laps.
• Write an inequality to show how many more laps Trevor needs to swim in order to raise more than $100.

Answers

Answer: L greater than 31

Step-by-step explanation:

Trevor is swimming laps to raise at over 100 dollars for the local food bank. He earns $1.85 per lap and has already swum 23 laps.

This means that the total amount that he has raised is number of laps that he has swum × the amount he earns per lap. Therefore,

Amount that he has already raised

= 1.85 × 23 = $42.55

100 - 42.55 = 57.45

He still needs to raise an amount greater than $57.45

To raise this amount, he needs to swim more laps. Number of laps that he needs to swim will be

57.45/1.85 = 31.05

Approximately 31 laps

Let the number of laps that he needs to swim be L

The inequality to show how many more laps Trevor needs to swim in order to raise more than $100 will be

L greater than 31

Have an awesome day! :)

To factor the quadratic x^2 + 3x + 2, it can be written as (x + 1)(x + 2). The concept of infinity over infinity (∞/∞) is an indeterminate form in limits and usually requires further techniques to evaluate.

To factor x^2 + 3x + 2, you want to find two numbers that both add up to +3 (the coefficient of x) and multiply to +2 (the constant term). These numbers are +1 and +2. Thus, you can express the quadratic equation as a product of two binomials:

x^2 + 3x + 2 = (x + 1)(x + 2).

As for the concept of limits like ∞/∞, it commonly arises when evaluating the behavior of functions as the variable approaches infinity. It represents an indeterminate form which requires further algebraic manipulation or techniques such as L'Hôpital's rule to find a meaningful limit.
