1- For what values of x will the expression log x be undefined?
2- put the following in order from smallest to largest : log^2 16, log 100, log^3 30, log^5 40, log ^20 200
3- if you invested money into an account that pays 9% a compounded weekly, how many years would it take for your deposit to double?
9- The function S(d)= 86log d +112 relates the speed of wind, S, in miles per hour, near the centre of a tornado to the distance the tornado travels, d, in miles. Estimate the rate at which the speed of the wind at the centre of the tornado is changing the moment it has traveled its 50th mile.
When x0 x 0, log x is NOT defined (undefined). As a result, when x is in [(−∞,0]), log x is undefined.
1) We are aware that only when x is positive is a logarithmic function, log x, defined. i.e., x>0 . Therefore, when x0 x 0, log x is NOT defined (undefined). As a result, when x is in [(−∞,0]), log x is undefined.
2) Order from smallest to largest:
[tex]log^{200}_{20} < log 100 < log^{5}_{40} < log^{3}_{60} < log^{2}_{16}[/tex]
3)
[tex]\(2A=A(1+\frac{0.09}{52})^{n}\\\\ 2=(1+\frac{0.09}{52})^{n}\\\\ log2=log(1+\frac{0.09}{52})^{n}\\\\ log2=nlog(1+\frac{0.09}{52})\\\\ n=log2\div log(1+\frac{0.09}{52})\\\)[/tex]
log(2)/log(1+0.09/52 = 400.831511360387616 weeks
400.831511360387616/52 = 7.708298295392069538
7.7 years
Hence, It take 7.7 years for deposit to double.

a)
[tex]S= 86 \ log d+112\\\\S= 86 log 50 +112\\\\S = 86*1.7+112\\\\S= 258.2[/tex]
S = 258.2 mph
b)
S = 258.2 mph ; find d
258 =86 log10 (d) + 112
146 = 86 log10 (d)
1.7 = log10 (d)

124.6135grams to the nearest kilogram
Answer: The correct answer is 0.1246135 kilograms
Step-by-step explanation:
1,000 grams = 1 kilogram
Therefore 124.6135 grams / 1000 = 0.1246135 kilograms
Answer:
124.6135 grams to the nearest kilogram would be none if you want to round how you are supposed to, or one if round to the next number up.
Step-by-step explanation:
What is 124.6135 grams compared to kilograms? Well, it's simple. A single kilogram has kilo in it. Kilo is a prefix meaning thousand, so therefor, a kilo gram is a thousand grams. since you have 124.6135 grams if you divide that by a thousand, you get 0.1246135. And using the rounding rule five or more, raise the score, four or less, let it rest; 1 is less than four so it would be zero.

What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence.Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty. Probability is a crucial subject because it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.Expected profit of the game =expected value received from this game- cost to play the game

which dimconstraint option allows you to create a dimensional constraint that has extension lines perpendicular to an angled surface?
Aligned Dim constraint option allows you to create a dimensional constraint that has extension lines perpendicular to an angled surface.
What are constraints?In CAD software, a constraint is a restriction or limitation placed on geometric properties by a designer or engineer: An entity in a design model that keeps its structure when the model is altered is referred to as type 203. In addition to relative length and angle, these properties may also include size, shift, and displacement.
The term "plural form constraints" refers to the delineations of geometrical characteristics between two or more entities or solid modelling bodies; these delimiters are definitive for properties of hypothetical physical position and motion, or displacement in parametric design. However, a CAD programme vendor may use different terminology than another.

Thus , probability of very last passenger getting seat comes out to be
P = 0.5 .
What is the process of probability?
Mathematics' field of probability deals with numerical representations of the possibility that an event will take place or that a statement is true. An event's probability is a number between 0 and 1, with 1 generally denoting certainty and 0 generally denoting impossibility.
Here,
If everyone chose at random, you would only have a 1/100 chance of receiving your own seat on a plane with 100 seats. However, in the context of this riddle, each participant does not make a random selection; rather, they only do so if all available seats have been occupied.
This indicates that half of the scenarios will resolve themselves (i.e., someone takes the mystery ticket holder's assigned seat allowing every subsequent passenger to take their assigned seat), while the other half will not resolve themselves and you will be seated in the incorrect location, making the probability of any plane occupancy equal to half.

What are basic theorems of Right angle Triangle?The Pythagoras Theorem defines the relationship between a triangle's perpendicular, hypotenuse, and base. The right-angled triangle theorem is another name for this. The Pythagoras theorem states that a triangle is said to be right-angled if the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be said in the following way:
If Angle equals 90° then Hypotenuse = Perpendicular∧2+ Base∧2.
The base is the side that the right angle is connected to, the neighboring side of the right angle is connected to the hypotenuse by the perpendicular, and the side that the angle is opposite to is known as the hypotenuse. The legs of the hypotenuse are another name for the base.

True
False
The answer is false just took the exam.
As of 1995, the human population was expected to double within 50 years. If we calculated r for the human population, we would get 1.39. statement is False.
To determine whether the statement is true or false, we need to calculate the doubling time (DT) based on the given growth rate (r) and see if it aligns with the expected doubling time of 50 years.
The formula to calculate the doubling time (DT) for a population with a constant growth rate (r) is:
DT = ln(2) / r
where ln is the natural logarithm (base e).
If the expected doubling time is 50 years, then:
DT = 50 years.
Now, we can calculate the value of r:
r = ln(2) / DT
Plugging in the values:
r = ln(2) / 50 ≈ 0.01386
Comparing the calculated value of r (approximately 0.01386) with the given value of 1.39, we can see that they are not the same.
Therefore, the statement is False. The calculated value of r (0.01386) does not match the given value of 1.39, and it would not result in the human population doubling within 50 years. In reality, with a growth rate of 1.39, the population would grow at an unsustainable rate, leading to an even faster increase in population over time.

suppose that a and b are independent events with p(a) 5 .5 and p(b) 5 .6. can a and b be mutually exclusive events?
Yes, Since a and b are independent event then therefore, a and b are mutually exclusive events.
P(a) +P(b) = 0.5+0.5
therefore, P(a ∪b) = 1.0
Mutually exclusive events are events that do not occur at the same time. For example, when you toss a coin, the result is either heads or tails, but you cannot get both results. Such events are also called disjoint events because they do not occur at the same time. If A and B are mutually exclusive events, their probabilities are given by P(A or B) or P(A U B).
According to the question:
P(a) = 0.5 and P(b)=0.5
therefore,
P(a) +P(b) = P(a ∪ b)
