Answer:
180
Step-by-step explanation:
A word has n letters.
There are m repeating letters, each of them repeating \(r_{0}, r_{1}, ..., r_{m}\) times
So the number of distincts ways the letters can be permutated is:
\(N_{A} = \frac{n!}{r_{1}! \times r_{2}! \times ... \times r_{m}}\)
In this question:
Extent has 6 letters.
E and r repeat 2 times. So
\(N = \frac{6!}{2!*2!} = 180\)
So the answer is 180.

Jose weighed himself on monday and he weighed 170 pounds. Two weeks later he weighed 165 pounds. write a linera function in the form y=mx+b to model jose's weight loss each week, where x is the number of weeks and y is joses weight. assume a constant weight loss over the two weeks.
Answer: Hello i am here to anwser your 2 part queston! <3
Step-by-step explanation:
the linear functon is Y= -2.5x+170
after 5 weeks he will have lost 157.5 lbs!!
The linear function in the form y = mx + b to model Jose's weight loss each week is → y = - 2.5x + 170.
What is linear function? What is a mathematical function, equation and expression? The linear function is given by → y = ax + bfunction : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Jose weighed himself on Monday and he weighed 170 pounds. Two weeks later he weighed 165 pounds.
The linear function is given by → y = ax + b. We can write the slope -
{a} = (165 - 170)/(2 - 0)
{a} = - 5/ 2
{a} = - 2.5
The linear function will become -
y = -2.5x + b
At [x] = 0, the value of [y] is 170.
So, the linear function can be written as -
y = - 2.5x + 170
Therefore, the linear function in the form y = mx + b to model Jose's weight loss each week is → y = - 2.5x + 170.

The error is with the order of subtraction in the formula for the distance between two points.
Heather did not make any errors in calculating the distance between two points. Therefore, the correct answer to the question above is (OD) She made no errors.
The formula for the distance between two points, A (x1, y1) and B (x2, y2), in the coordinate plane is given as;
dAB = \(\sqrt{ ((x^2 - x1)^2 + (y2 - y1)^2)\)
Comparing the given question with the formula above, we have;
A = R (-3, -4) and B = S (5, 7)The distance, AB = RS.
Therefore, we have;
RS = \(\sqrt{ ((5 - (-3))^2 + (7 - (-4))^2)\)
On solving the above equation;RS = \(\sqrt{ ((5 + 3)^2 + (7 + 4)^2)\)RS
= \(\sqrt{ (8^2 + 11^2)RS\)
= \(\sqrt{ (64 + 121)RS\)
= \(\sqrt{ (185)\)
Therefore, the distance between points R and S is \(\sqrt{ (185)\).
From the calculation, it is clear that Heather did not make any errors while calculating the distance between two points. The answer obtained by Heather is correct.

F. What does the answer from part E tell us about the trout population?
The answer from part A tells us that the trout population was 10 in the first month after it was introduced.
How solve the problem?A. P(0) = 740 / (1 + 73e^-0) = 740 / (1 + 73) = 740 / 74 = 10, so the answer is 10.
B. The answer from part A tells us that the trout population was 10 in the first month after it was introduced.
C. To find the number of trout in the lake after 1 year, we need to find P(12): P(12) = 740 / (1 + 73e^-0.07*12) = 740 / (1 + 73e^-0.84) ≈ 490, so the answer is 490.
D. To find the number of trout in the lake after 10 years, we need to find P(120): P(120) = 740 / (1 + 73e^-0.07*120) = 740 / (1 + 73e^-8.4) ≈ 740, so the answer is 740.
E. lim t→∞ P(t) = 740, so the answer is 740.
F. The answer from part E tells us that as the number of months t approaches infinity, the trout population will approach 740. This means that the trout population will eventually stabilize at 740 if no other factors such as predators, disease, or lack of food affect the population.

What are the domain and range of the function
Therefore, the domain is (-∞, ∞) and the range is (-∞, ∞) for the given function.
What is function?In mathematics, a function is a relation between a set of inputs (called the domain) and a set of possible outputs (called the range) with the property that each input is associated with exactly one output. In other words, a function is a rule that assigns a unique output value to each input value.
Here,
To find the domain and range of the function f(x) = -1/4(x³ + 6x² + 5x - 4), we need to consider the restrictions on x and the possible values of f(x).
Domain:
Since the function involves a cubic expression in the numerator, there are no restrictions on x, and the domain of the function is all real numbers, or (-∞, ∞).
Range:
To find the range of the function, we need to consider the behavior of the cubic expression as x goes to positive infinity or negative infinity. As x becomes very large or very small, the dominant term in the expression becomes x³, and the other terms become negligible. The coefficient of x³ is negative, which means that the cubic expression approaches negative infinity as x goes to negative infinity and approaches positive infinity as x goes to positive infinity.
Therefore, as x approaches negative infinity, f(x) approaches positive infinity, and as x approaches positive infinity, f(x) approaches negative infinity. Hence, the range of the function is all real numbers, or (-∞, ∞).

If f and g are both even functions, is the product fg even? If f and g are both odd functions, is fg odd? What if f is even and g is odd?
F g - x hence equals -f x. -g x. It follows from this that f g - x = f g x. Given that f and g are two odd functions, it follows that f g is an even function. As a result, f g is not an unusual function.
What is meant by odd function?If the equation for every x and x in the domain of f holds, then a function f is odd. F(x)=F(x) or F(x)=F(x) An odd function has a graph that, geometrically speaking, is rotationally symmetric with respect to the origin, meaning that the graph is unaffected by a 180° rotation of the origin.
If f - x = f x, then a function f x is said to be even. These functions have symmetric properties around the y-axis.
F - x Equals F x if two functions f and g are two even functions.
g - x = g x
Now, the definition of the product function f g is as follows:
\($f g x=f x \cdot g x$\)
Analyze the fg at -x product function.
\($f g-x=f-x \cdot g-x$\)
The two functions are currently equal functions. Utilize the knowledge that f - x = f and g - x = g.
Consequently, f g - x = f x. g x It follows from this that f g - x = f g x. This suggests that f g, where f and g are two even functions, is an even function.
If f - x = -f x, then a function f x is said to be odd. These functions have symmetry at their origin.
If f and g are two odd functions, then f - x = -f x and g - x = -g x, respectively.
Now, the definition of the product function f g is as follows:
\($f g x=f x \cdot g x$\)
Evaluate the product function f g at -x
\($f g-x=f-x \cdot g-x$\)
The two functions are now peculiar functions. Utilize the knowledge that f-x = -f-x and g-x = -g-x.
F g - x hence equals -f x. -g x. It follows from this that f g - x = f g x. Given that f and g are two odd functions, it follows that f g is an even function. As a result, f g is not an unusual function.
Assume that g is odd and f is even. G - x = -g x and f - x = f x, respectively.
The following is a definition of the product function:
\(f g-x & =f-x \cdot g-x \\\)
\(& =f x \cdot-g x \\\)
\(& =-f x \cdot g x \\\)

What is meant by tangent?
A plane or straight line that meets a curve or curved surface at a particular place but does not cross it when extended.
Given function is f(x)=4-2secx
We can write it as
