In circle M, segment AB is tangent to the circle at point C. AB has endpoints such that AM BM ,
AC 9 and BC 4 . What is the length of the radius of circle M. Show how you arrived at your answer.
Answer:
6
Step-by-step explanation:
We can use the geometric mean theorem:
The altitude on the hypotenuse is the geometric mean of the two segments it creates.
In your triangle, the altitude is the radius CM and the segments are AC and BC.
[tex]CM = \sqrt{AC \times BC} = \sqrt{ 9 \times 4} = \sqrt{36} = \mathbf{6}\\\text{The radius of the circle M is $\large \boxed{\mathbf{6}}$}[/tex]
The length of the radius of the circle is 6 units
How to determine the radius of the circle?The given parameters are:
AC = 9
BC = 4
To calculate the radius (r), we make use of the following equation:
[tex]r = \sqrt{AC * BC}[/tex]
Substitute known values
[tex]r = \sqrt{9 * 4}[/tex]
Evaluate the product
[tex]r = \sqrt{36}[/tex]
Evaluate the square root
[tex]r = 6[/tex]
Hence, the length of the radius of the circle is 6 units

Will a set of data always have a mode? Explain your answer.
A set of data will not always have a mode.
A mode is defined as the value that appears the most often in a set.
For instance, a set of 1, 2, 3, 3, 4, 4, 4, 4, 4, 5, 5, 5, 6 would have a mode of 4, as it appears more often than any other number in the set.
However, a set of 1, 2, 3, 4, 5, 6 has no mode as there is no number that appears more than other numbers in the set.

Factor x^4+xy^3+x^3+y^3 out completely. Hint: first factor out a monomial.
pls put the explanation and thank uu
Answer:
(x + y)(x² - xy + y²)(x + 1)
Step-by-step explanation:
Given
[tex]x^{4}[/tex] + xy³ + x³ + y³ ( factor out x from the first 2 terms )
= x(x³ + y³) + 1(x³ + y³) ← factor out (x³ + y³) from each term

Which of the points is NOT one of the vertices (s,t) of the shaded region of the set of inequalities shown below?
Please help
Answer:
Option D
Step-by-step explanation:
Given: set of inequalities
To find: Points which do not satisfy all the inequalities
Solution:
For point [tex](15,0)[/tex]:
[tex]15\leq 30-3(0)=30\\15\geq 15-0=15\\15\leq 25-0=25\\15\geq 0\\0\geq 0[/tex]
So, (15, 0) satisfies all the inequalities
For point [tex](7.5,7.5)[/tex]:
[tex]7.5\leq 30-3(7.5)=30-22.5=7.5\\7.5\geq 15-7.5=7.5\\7.5\leq 25-7.5=17.5\\7.5\geq 0\\7.5\geq 0[/tex]
So, (7.5, 7.5) satisfies all the inequalities
For point (22.5,2.5):
[tex]22.5\leq 30-3(2.5)=30-7.5=22.5\\22.5\geq 15-2.5=12.5\\22.5\leq 25-2.5=22.5\\22.5\geq 0\\2.5\geq 0\\[/tex]
So, (22.5,2.5) satisfies all the inequalities
For point (7.5 ,0):
Put s = 7.5 and t = 0 in [tex]s\geq 15-t[/tex]
[tex]7.5\geq 15-0=15[/tex] which is false
So, [tex](s,t)\neq (7.5,0)[/tex]

What are the leading coefficient, constant term and degree, if any, of the algebraic expression (x - 1)(x^2+1)
a. leading coefficient: 1; constant term: -1; degree: 3 b. leading coefficient: -1; constant term: 1; degree: 3
c. leading coefficient: 1; constant term: 1; degree: -3. d. none, expression is not a polynomial
Answer:
See below in bold.
Step-by-step explanation:
(x - 1)(x^2 + 1)
= x(x^2 + 1) - 1(x^2 + 1)
= x^3 + x - x^2 - 1
= x^3 - x^2 - x - 1.
Leading coefficient = 1.
Constant term = -1.
Degree = 3. (because of the x^3).
If the algebraic expression is (x - 1)(x² + 1). The leading coefficient is 1, the constant term is -1 and the degree is 3. Option A is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that the expression is,
(x - 1)(x² + 1)
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
=(x - 1)(x²+ 1)
= x(x² + 1) - 1(x² + 1)
= x³ + x - x² - 1
= x³ - x² - x - 1.
From the expression the obtained result is,
Leading coefficient = 1
Constant term: -1
Degree: 3
Thus, if the algebraic expression is (x - 1)(x² + 1). The leading coefficient is 1, the constant term is -1 and the degree is 3. Option A is correct.

What is 1,000,000,000,000 as a power of 10?
Answer:
1,000,000,000 as a power of 10, is: 10^12
Step-by-step Solution:
We can expand 1,000,000,000, and write this number as a multiplication sentence using only the number 10. By doing this, we can count the number of tens needed to be multiplied to get to his answer:
1,000,000,000 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10
Since 10 is multiplied by itself 12 times, we can therefore say that 10^12 is equal to 1,000,000,000
Answer:
10^12 (10 to the 12th power)
Step-by-step explanation:
10 to the twelth power would basically be 10x10x10x10x10x10x10x10x10x10x10x10
This equals 1,000,000,000,000, which is one trillion.
ernie and lori are playing a game. the table shows their scores for 5 times they have played the game. which statement is true?
the medians are equal.
ernie has the greater range.
the means are equal.
ernie has the greater mode.
Answer:
Ernie has a greater range
The statement "the medians are equal" is true for the given table of data about playing a game by Ernie and Lori. This is obtained by calculating the mean, median, mode, and range of the data elements of each.
What are the mean, median, mode, and range for a set of data?Mean: This gives the average value of the data set and is calculated by adding all the elements in the data set and the result is divided by 2.Median: This is the middle value of the data set and it is calculated by rearranging the data in numerical order and then finding [tex]\frac{n}{2}[/tex] or [tex]\frac{n+1}{2}[/tex] for an even or odd number of data elements respectively.Mode: This gives the value that occurs most often in the data set.Range: The difference between the largest and smallest values of the data set is said to be the range.Calculating all the values for both Ernie and Lori:Given data sets for Ernie and Lori as follows:
Ernie: {18, 24, 17, 19, 17} and Lori: {16, 22, 18, 14, 18}
The number of elements in both the data sets is equal and it is 5
Calculating Mean:
For Ernie: {18, 24, 17, 19, 17}
Mean=(18+24+17+19+17)/2
=19
For Lori: {16, 22, 18, 14, 18}
Mean=(16+22+18+14+18)/2
=17.6
Thus, their "means are not equal". (3rd statement is false)
Calculating Median:
For Ernie: {18, 24, 17, 19, 17}
Re-arranging the data - 17, 17, 18, 19, 24
Since n=5 (odd), then the median is at (5+1)/2 th term i.e., 3rd term
So, the median is 18
For Lori: {16, 22, 18, 14, 18}
Re-arranging the data - 14, 16, 18, 18, 22
Since n=5 (odd), then the median is at (5+1)/2 th term i.e., 3rd term
So, the median is 18
Thus, their "medians are equal". (first statement is true)
Calculating Mode:
The most occurring number in Ernie: {18, 24, 17, 19, 17} is 17 and
The most occurring number in Lori: {16, 22, 18, 14, 18} is 18
Thus, their modes are not equal, and "Lori has the greater mode".
(4th statement is false)
Calculating Range:
The range for Ernie's data set is 24 - 17=7
The range for Lori's data set is 22 - 14=8
Thus, their ranges are also not equal but "Lori has the greater range".
(2nd statement is false).
Therefore, 1st statement - " the medians are equal" is true.

What is the 15th term of the sequence 4,-8, 16, -32, 64...?
Answer: 16384
Step-by-step explanation:
The 15th term of the geometric sequence 4,-8, 16, -32, 64... is 131072. The term is obtained by using the formula for the nth term of a geometric sequence.
Explanation:The sequence given is a geometric sequence. This means every term is obtained by multiplying the previous term by a constant. In this case, the constant is -2 (since -8 = 4*-2, 16 = -8*-2, -32 = 16*-2, etc).
The formula for the nth term of a geometric sequence is a*r^(n-1), where a is the first term, r is the ratio (constant), and n is the position of the term in the sequence. In this case, the first term a is 4 and the ratio r is -2. Substituting these values and n=15 into the formula, we get the 15th term as 4*(-2)^(15-1) = 131072.
Therefore, the 15th term of the sequence 4,-8, 16, -32, 64... is 131072. This can be found by applying the formula for the nth term of a geometric sequence and substituting the given values.

how do you graph y = -4/3x+8
Answer:
Below.
Step-by-step explanation:
The y-intercept of the graph is at (0, 8)
Plugging in x = 0 we get y = -4/3 * 0 + 8 = 8.
So we can mark 2 points on the graph paper.
One is at (0, 8).
If we let x = 3 then y = -4/3 * 3 + 8
y = -4 + 8
y = 4.
So our second point is at (3, 4)
We draw a line through these 2 points to get our graph.

Answer:
D. more than 102
E. between 90 and 102 messages

Step-by-step explanation:
The median number of texts is 90, with approximately 25 students sending fewer than 78 texts (Q1) and 25 sending more than 102 texts (Q3) per day.
Explanation:For a sample of 100 students, the median number of text messages sent per day is 90, the first quartile (Q1) is 78, and the third quartile (Q3) is 102. This implies that approximately 25 students in the sample send fewer than 78 text messages per day (since Q1 marks the 25th percentile) and approximately another 25 students send more than 102 text messages per day (since Q3 marks the 75th percentile). Hence, the interquartile range (IQR), which measures the middle 50% of the data, is the difference between the third and first quartiles, which is 102 - 78 = 24 messages.

Step-by-step explanation:
On a coordinate plane, coordinates of the points J, K and L are (-2, 1), (0, 3) and (2, -1) respectively.
If we reflect these points over the line x = 0 or y-axis, rule to be followed is
(x, y) → (-x, y)
Only sign of x coordinates get changed while y coordinates remain the same.
