Final answer:
To find the outside temperature T when the temperature of dry ice is -109.3°F, and it is 184.9°F less than the outside temperature, we simply need to add those two numbers. The outside temperature T is found to be 75.6°F.
Explanation:
The student is asked to find the outside temperature T given that the temperature of dry ice is −109.3°F. The temperature of dry ice is 184.9°F less than the outside temperature. To find the outside temperature, we can set up the following equation:
T = (-109.3°F) + 184.9°F
Now, we simply add the two numbers to solve for T:
T = 75.6°F
The calculation shows that the outside temperature T is 75.6°F.
What is the difference between advanced calculus and real analysis?
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.

What values of c and d make the equation true?
c = 2, d = 2
c = 2, d = 4
c = 6, d = 2
c = 6, d = 4
Answer:
c=6 and d=2 makes the equation true
Step-by-step explanation:
[tex]\sqrt[3]{162x^cy^5} = 3x^2y(\sqrt[3]{6y^d})[/tex]
plug in c=2 and check
[tex]\sqrt[3]{162x^2y^5}[/tex]
We cannot simplify cuberoot (x^2)
So c=2 does not works
Lets try with c=6 and d=2
[tex]\sqrt[3]{162x^6y^5}[/tex]
Cuberoot(x^6) = x^2
cuberoot (y^5)= ycuberoot (y^2)
[tex]\sqrt[3]{162x^6y^5} = 3x^2y(\sqrt[3]{6y^2})[/tex]
So c=6 and d=2 makes the equation true

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

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.
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

factor x^2 + 3x + 2
infinity/infinity
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.
Classify the following triangle.Check all that apply.
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.
The complete question is: Classify the following triangle.Check all that apply.

The average yearly snowfall in chillyville is normally distributed with a mean of 55 inches. if the snowfall in chillyville exceeds 60 inches in 15% of the years, what is the standard deviation?
The standard deviation of the snowfall in Chillyville, when the snowfall exceeds 60 inches in 15 percent of the years, is 5 inches.
Explanation:The question is about finding the standard deviation of the normally distributed data for snowfall in Chillyville. From the given problem, we have the mean (μ) as 55 inches and the given probability for snowfall exceeding 60 inches is 15% or 0.15 which happens to correspond to 1 - 0.85 = 0.15 in the standard normal distribution. This places it in the 85th percentile of the standard normal distribution, which corresponds to a Z-score of about 1.
From the Z-score formula Z = (X - μ)/σ, where X is the data point, μ is the mean and σ is the standard deviation, we can substitute the known values: 1 = (60 - 55)/σ . Solving it gives σ = 60 - 55, which implies the standard deviation is 5 inches.
