Given:
A right-angled triangle.
The value of the base is 12 units.

There are 51 runners in a race. how many ways can the runner finish first, second and third
Answers
Answer: 124950
Step-by-step explanation:
So, let’s look at this logically. For first place, you can any one of the 51 runners finish there. For 2nd place, you can have any one of the remaining 50 runners finish there. For 3rd place, you can have any one of the 49 runners who haven’t finished finish there. runners who haven’t finished finish doesn’t matter .So, you take all of the possibilities, and times them together, 51*50*40 different possibilities.Now, if you want a generic equation, you can run it through this equation, x being the number of possibilities, and n being the number of ones your choosing:

Describe how the graph of
g(x) = 4(0.5)x - 3
compares to the graph of
f(x) = 4(0.5)x .
Answers
Answer:
the graph of g(x) will be the same shape as the graph of f(x), but shifted downward by 3 units.
Step-by-step explanation:
The functions g(x) = 4(0.5)^x - 3 and f(x) = 4(0.5)^x are both exponential functions with the same base of 0.5 and the same coefficient of 4.
However, the graph of g(x) will be shifted downward by 3 units compared to the graph of f(x), because of the constant subtraction of 3 at the end of the function. This shift will occur for all values of x, meaning that the distance between the two graphs will remain constant as x changes.
In other words, the graph of g(x) will be the same shape as the graph of f(x), but shifted downward by 3 units.
Solve the equation AB=BC for A, assuming that A,B and C are square matrices and B is invertible.
Answers
The solution of AB = BC for A, assuming that A,B and C are square matrices and B is invertible is [tex]A = BCB^{-1}[/tex]
We have to solve the equation
AB = BC , given that these all are square matrices and B is invertible.
Write the required Equation:
AB = BC
Multiply both sides by inverse of B
The multiplicative inverse of a matrix is the matrix that gives you the identity matrix when multiplied by the original matrix.
Matrix multiplied by an identity matrix, the result is always the same original non-identity (non-unit) matrix, and thus, as explained before, the identity matrix gets the nickname of "unit matrix"
[tex]ABB^{-1} = BCB^{-1}\\AI = BCB^{-1}\\A = BCB^{-1}[/tex]

mathematical evidence to justify your answer.
Answers
AB and CD are not parallel lines.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
If the slope of AB and CD are equal then the lines are parallel.
A(-3, 5), B(1, 13), C(4, 2), and D(10, 5)
AB=13-5/1+3
=8/4=2
CD=5-2/10-4

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.
In given two triangles,
RST and NLM
In the triangle RST ,
The sum of angles is 180
so,
44 + 15 + S = 180
S = 180 - 59
S = 121
And similarly in the triangle NLM,
N + 121 + 44 = 180
N = 180 - 165
N = 15
Therefore, The values of given angles S and N are 121 , 15 respectively
SR / ML = 3.61 / 5.415 = 0.667
ST / MN = 9.71 / 14.565 = 0.667

Answers
All 4 helpers will be at the clinic on the same day 7 times in 12 weeks.
What is Prime Factorization?
"Prime Factorization" is the process of determining which prime numbers multiply together to get the original number.
To find the number of times in 12 weeks that all 4 helpers will be at the clinic on the same day, we need to find the least common multiple (LCM) of the numbers 4, 6, 2, and 3.
First, we can find the prime factorization of each number:
4 = 2 x 2
6 = 2 x 3
2 = 2
3 = 3
Next, we can find the LCM by taking the highest power of each prime factor that appears in the factorizations:
LCM = 2 x 2 x 3 = 12
Therefore, all 4 helpers will be at the clinic on the same day every 12 days. Since 12 weeks is equivalent to 84 days, we can divide 84 by 12 to get the number of times:
84 ÷ 12 = 7
So, all 4 helpers will be at the clinic on the same day 7 times in 12 weeks.

If two events are collectively exhaustive, what is the probability that both occur at the same time?
a) 0. b) 0.50. c) 1.00. d) Cannot be determined from the information given
Answers
If two events are collectively exhaustive, then the probability that both occur at the same time is 1.00 (Option c)
What do you mean by Probability?Probability is a quantification of how likely an event is to occur. Typically, probabilities are defined as the chances that a specific outcome will occur out of a given selection of outcomes. A probability is expressed mostly in decimal form, taking values between 0 and 1. Probabilities cannot exceed this particular range of values.
Firstly, To clarify : You are confusing mutually exclusive and jointly collectively exhaustive.
The former describes condition which cannot both (or all) obtain. and so exclude one another.
i.e., "not - (both A and not - A)"
The latter describes conditions, one of which must obtain, and so exhaust the field of possibilities. i.e., "either A or not - A"
I presume you intend to refer to the latter.
Second, to answer your question: If two events - are jointly exhaustive, their probabilities must by definition sum to 1.
It is thus certain, not merely probable, that one or the other will obtain.

what will be the value of |2-3i| ?
Answers
The value of complex number |2 - 3i| will be, 3.605
What is a complex number ?A complex number is one that has the formula a + bi, where I is the imaginary unit and a and b are real numbers. A and b are the real and imaginary halves of a complex number, respectively.
In order to expand the real number system to include answers to polynomial equations that couldn't be solved with just real numbers, complex numbers were first introduced. Many branches of mathematics and science, such as computer science, physics, and engineering, are based on the idea of a complex number.
The absolute value of a complex number "a + bi" can be calculated as the square root of the sum of the squares of its real and imaginary parts:
|a + bi| = √(a² + b²)
In this case, a = 2 and b = -3, so:
|2 - 3i| = √(2 + (-3)²)
= √(4 + 9)
= √(13)
= approximately 3.6055
So, the value of |2 - 3i| is approximately 3.6055.

How do you validate a min-heap?
Answers
To validate a min-heap, you can follow these steps: Start at the root, Check each subtree, Repeat the process recursively, If any node violates the min-heap property, then the heap is not valid.
Start at the root: Verify that the value at the root node is the minimum value in the heap. This is the defining property of a min-heap. Check each subtree: For each subtree, check that the value at the root of the subtree is less than or equal to the values of its child nodes. If this property holds true for all subtrees, the heap is a valid min-heap. Repeat the process recursively: Continue the above steps for each subtree until all nodes have been checked. If any node violates the min-heap property, then the heap is not valid. In that case, you can either rebuild the heap or identify the specific node or subtree that violates the property and fix it. In summary, to validate a min-heap, you need to check that the root node contains the minimum value, and each subtree obeys the min-heap property. You can check the property recursively until all nodes have been verified, and identify any nodes that violate the property for correction.

Step-by-step explanation:
You want to know if scatter plot or a line graph more appropriate to construct for seeing the relationship between a manatee's weight and height.
VariablesThe variables involved are "weight" and "height". Notice that "time" is not involved. (This eliminates choices B and D.)
GraphA line graph is useful for showing how one variable relates to another as the value of one variable changes. It would be useful for plotting the weight and height of one animal as it changes during the animal's lifetime.
When multiple animals are involved, a scatter plot might be more helpful for showing the relationship.
The context is given as "a manatee's weight and height", not "manatees' weight and height." Hence it seems we can assume that we're looking at data for only one animal.
The appropriate graph would be ...
