The square root of 138 lies between 11 and 12, as 11²=121 and 12²=144.
What is number?Number is a mathematical object used to count, measure, and label. Numbers are used in almost every field of mathematics and science, including algebra, calculus, geometry, physics, and computer science. Numbers can also be used to represent data, such as population, income, temperature, or time. In addition, numbers are used to represent abstract concepts, such as love, truth, beauty, and justice.
This is because the square root of a number is the number that, when multiplied by itself, produces the original number. Therefore, to find the square root of 138, we need to identify two consecutive integers such that one of them squared is smaller than 138 and the other squared is larger than 138.
To do this, we can work our way up from the integer closer to 0, in this case 11. 11 squared is 121, which is smaller than 138, so we know that the square root of 138 must be between 11 and a larger integer. Then, if we square 12, we get 144, which is larger than 138. Therefore, we can definitively say that the square root of 138 lies between 11 and 12.

The area of a sector of a circle with a central angle of 5 radians is 15cm². Find the radius of the circle.
Do not round any intermediate computations. Round your answer to the nearest tenth.
The area of a sector of a circle is equal to the central angle in radians multiplied by the square of the radius.
Therefore, we can use this formula to solve for the radius:
Area = (Central Angle) × (Radius)²
Therefore, we can rearrange this formula to solve for the radius:
Radius = √(Area / Central Angle)
Plugging in the values given, we get:
Radius = √(15 cm² / 5 rad)
Simplifying, we get:
Radius = 3 cm
Therefore, the radius of the circle is 3 cm, rounded to the nearest tenth.

how many positive perfect square integers are factors of the product $\left(2^{10}\right)\left(3^{12}\right)\left(5^{15}\right)$?
By the multiplication principle of counting, the total number of positive perfect square factors of the product is the product of the number of choices for each prime factor, which is $6\times7\times8=336$. Therefore, 336 positive perfect square integers are factors of(2¹⁰ )(3¹² )(5¹⁵)
We can find the number of positive perfect square integers that are factors of the given product by first considering the prime factorization of the product, which is (2¹⁰ )(3¹² )(5¹⁵)
To get a perfect square factor, we need each prime factor to have an even exponent. Therefore, we can choose any even exponent for the prime factors of 2, 3, and 5, respectively, as long as the exponents are not greater than 10, 12, and 15, respectively.
For the factor of 2, we can choose any even exponent from 0 to 10, so there are 6 choices. Similarly, for the factor of 3, we can choose any even exponent from 0 to 12, so there are 7 choices. Finally, for the factor of 5, we can choose any even exponent from 0 to 15, so there are 8 choices.

Here are the 4 Theorems you can choose from:
1. Angle Sum Theorem

4. Corollary of Exterior Angle Theorem
I chose to explore the Angle Sum Theorem because it is a fundamental theorem in geometry, and it has important implications for many geometric proofs and applications. Moreover, the theorem can be easily visualized and understood, making it a great starting point for learning geometry.
What is the theorem about?The formal definition of the Angle Sum Theorem is: "In any triangle, the sum of the interior angles is equal to 180 degrees."
In simpler terms, the Angle Sum Theorem states that if you add up all the angles inside a triangle, you will always get a total of 180 degrees. This means that no matter how you move the sides of the triangle or what shape it takes, the total measure of the angles will always be the same.
Let's consider a triangle with angles of 30 degrees, 60 degrees, and 90 degrees. According to the Angle Sum Theorem, the sum of the interior angles of any triangle must be 180 degrees.
So, in this case, we have:
30 degrees + 60 degrees + 90 degrees = 180 degrees
Therefore, the Angle Sum Theorem holds true for this example.
I taught the Angle Sum Theorem to my younger brother, and he was fascinated by it. He said that he had never thought about triangles in this way and found it cool that the angles always added up to the same number, no matter what the triangle looked like. He then went on to ask me more questions about triangles and geometry, which I was happy to answer.

Marcia Gadzera wants to retire in San Diego when she is 65 years old. Marcia is now 50 and believes she will need $90,000 to retire comfortably. To date, she has set aside no retirement money. If she gets interest of 10% compounded semiannually, how much must she invest today to meet her goal of $90,000?
Answer:
Step-by-step explanation:
We can use the formula for the future value of an annuity to determine how much Marcia needs to invest today to meet her retirement goal of $90,000. The formula for the future value of an annuity is:
FV = PMT x [(1 + r/n)^(n*t) - 1] / (r/n)
where:
FV = future value of the annuity
PMT = payment (or deposit) made at the end of each compounding period
r = annual interest rate
n = number of compounding periods per year
t = number of years
In this case, we want to solve for the PMT (the amount Marcia needs to invest today). We know that:
Marcia wants to retire in 15 years (when she is 65), so t = 15
The interest rate is 10% per year, compounded semiannually, so r = 0.10/2 = 0.05 and n = 2
Marcia wants to have $90,000 in her retirement account
Substituting these values into the formula, we get:
$90,000 = PMT x [(1 + 0.05/2)^(2*15) - 1] / (0.05/2)
Simplifying the formula, we get:
PMT = $90,000 / [(1.025)^30 - 1] / 0.025
PMT = $90,000 / 19.7588
PMT = $4,553.39 (rounded to the nearest cent)
Therefore, Marcia needs to invest $4,553.39 today in order to meet her retirement goal of $90,000, assuming an interest rate of 10% per year, compounded semiannually.

One type of flower is growing in a pond. The flowers F in the pond are growing exponentially.
0 200
1 800
Answer:
The function that models the number of flowers, F(t), is given as F(t) = cd, where c and d are constants. We need to find the values of c and d in order to write the equation for the number of flowers in the pond at time, t.
From the table, we know that when t=0, F(t) = 200. This means that:
F(0) = cd = 200
Similarly, when t=1, F(t) = 800. This means that:
F(1) = cd = 800
We can solve this system of equations for c and d by dividing the second equation by the first equation:
F(1)/F(0) = 800/200
4 = d/c
Now we can substitute the value of d/c into either equation to solve for one of the constants. Let's use the first equation:
cd = 200
c(d/c) = 200
d = 200/c
Substituting this into the equation d/c = 4, we get:
4 = d/c = (200/c) / c
4c = 200
c = 50
Now we can find the value of d using d = 200/c:
d = 200/50 = 4
Therefore, the equation for the number of flowers in the pond at time, t, is:
N(t) = cd = 50(4) = 200
So, the answer is N(t) = 200(1), which means that at any time t, the number of flowers in the pond is 200.

What is equation?In mathematics, an equation is a statement that two expressions are equal. The equation consists of her two sides divided by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the statement "2x + 3" equals the value "9". The goal of solving an equation is to find the values of the variables to make the equation true. Simple or complex equations, regular or nonlinear, and equations involving one or more factors are all possible. For example, the expression "x2 + 2x - 3 = 0" squares the variable x. Lines are used in many areas of mathematics, including algebra, calculus, and geometry.

Find theangle to the nearest degree. To the nearest mile,how many miles would be saved by travelingdirectly from New York City to Buffalo rather thanby traveling first to Albany and then to Buffalo?
By using trigonometry, we find that Traveling directly from New York City to Buffalo would save approximately 50 miles.
To find the angle at which the engineer should build the highway, we can use trigonometry. Let's call the distance between New York City and Buffalo "d". Then, the distance traveled if going through Albany would be 170 + 280 = 450 miles.
We can use the cosine function to find the angle x:
cos(x) = adjacent/hypotenuse = d/450
x = cos^(-1)(d/450)
To find the value of x, we need to know the value of d. If we assume that the distance between New York City and Buffalo is approximately 400 miles, then:
x = cos^(-1)(400/450) = 23.6 degrees (rounded to the nearest tenth)
Therefore, the engineer would need to build the highway at an angle of approximately 23.6 degrees.
To find how many miles would be saved by traveling directly from New York City to Buffalo rather than going through Albany, we can subtract the distances:
450 - d = 450 - 400 = 50 miles (rounded to the nearest mile)
Therefore, traveling directly would save approximately 50 miles.

The values of x for which the series converges is x ∈ (-1/5, 1/5). The sum of the series for those values of x is (-5x)/(1 + 5x).
The series is [tex]\Sigma^{\infty}_{n=1}(-5)^nx^n[/tex].
We can write this series as [tex]\Sigma^{\infty}_{n=1}(-5x)^n[/tex].
This is a infinite geometric series with first term a = -5x and common ration r = -5x.
It is convergent when
|r| < 1
|-5x| < 1
|-5| |x| < 1
5|x| < 1
Divide by 5 on both side, we get
|x| < 1/5
The series is convergent when x ∈ (-1/5, 1/5).
Sum of the series is
Sₙ = a/1 - n
Sₙ = (-5x)/{1 - (-5x)}
Sₙ = (-5x)/(1 + 5x)

The probability of drawing three kings in a row from a standard deck of cards when the drawn card is not returned to the deck each time is..................
The probability of drawing three kings in a row from a standard deck of cards when the drawn card is not returned to the deck each time is 0.000055
The multiplication rule of probability can be used to determine the likelihood of drawing three kings consecutively from a standard deck of cards when the drawn card is not put back into the deck each time.
Since there are four kings in a deck of 52 cards, the likelihood of drawing a king from a standard 52-card deck is 4/52 or 1/13.
There are still 51 cards in the deck after the first king is drawn, and three of them are kings. Therefore, there is a 3/51 chance of drawing another king.
There are 50 cards left in the deck after drawing the second king, and two of them are kings. The likelihood of drawing a third king is therefore 2/50 or 1/25.
Therefore, the probability of drawing three kings in a row from a standard deck of cards when the drawn card is not returned to the deck each time is:
(1/13) x (3/51) x (1/25) = 3/54,600 or approximately 0.000055.
Hence, 0.000055 is the probability of drawing three kings in a row from a standard deck of cards when the drawn card is not returned to the deck each time.
