The degrees of the whole segment is 90 because we know that a right angle is 90 degrees and can be shown with a square in the corner. One angle inside the 90 degrees is 50 degrees and the other two values are the same. Since 90 - 50 = 40, we know that the remaining is 40 degrees. Since x is the same, we divide 40 by 2, getting 20 degrees.
ANSWER: x = 20 degrees

No, it is not it true that for any integer n ≤ 2, φ(n) has a primitive root
What is primitive root?In modular arithmetic, a number g is called a primitive root modulo n if every number coprime to n is congruent to a power of modulo . Mathematically, g is a primitive root modulo n if and only if for any integer a such that gcd(a, n)=1 , there exists an integer k such that:
.[tex]g^{k}[/tex]≡ a (mod n)
Now,
Existence of Primitive root modulo n exists if and only if:
n is 1, 2, 4, orn is power of an odd prime number , orn is twice power of an odd prime number .So,
if n be a positive integer. A primitive root mod n is an integer g such that every integer relatively prime to n is congruent to a power of g mod n.
For example,
As ϕ(11)=10, the order of 2(mod11) must divide 10.
So we check 22≡4(mod11) and 25≡10(mod11).
Since neither of these are 1, and
we know 2ϕ(11)=210≡1(mod11) by Euler's Theorem,
ord112=ϕ(11), making 2 a primitive root modulo 11.

Given [tex]f(x)=\frac{1}{x+5}[/tex], find the average rate of change of f(x) on the interval

Pls halp
Answers
The average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h
How to find the average rate of change of f(x) on the interval [1,1+h]?The function is given as
f(x) = 1/(x + 5)
The interval is given as
[1, 1 + h]
Calculate f(1) as follows
So, we have
f(1) = 1/(1 + 5)
f(1) = 1/6
Calculate f(1 + h) as follows
So, we have
f(1 + h) = 1/(1 + h + 5)
f(1 + h) = 1/(h + 6)
The average rate of change of f(x) on the interval [1,1+h] is then calculated as
Rate = [f(1 + h) - f(1)]/[1 + h - 1]
This gives
Rate = [1/(h + 6) - 1/6]/h
Hence, the average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h

5,435,778 in scientific notation will be 5.435778×10⁶.
Scientific notation is the way to represents huge numbers in simple form. This ease understanding and calculation of the numbers. When written in a scientific notation, the number is called coefficient, the number to which power is raised is called base and raised power is called exponent. For instance, in the given answer, 5.435778 is coefficient, 10 is base and 6 is exponent.
While converting the numbers into scientific notation, we need to remember following points -
If the number is greater than 1 or is a multiple of 10, the decimal will be placed on the Left Hand Side. Like in the number in question, decimal moved to left and we got positive exponent. If the number is less than 1, then decimal will be placed at Right Hand Side. In this case, the exponent will be negative.

Rhiannon and Sophie both started saving for a new piano this month. Rhiannon will deposit $35.80 per week, but her bank account is currently overdrawn with a -$253.50 balance. Sophie also has a negative bank account balance of -$78.25 and will deposit $23.30 each week. How many weeks (w) will it take for the two bank accounts to have the same balance?
Answers
It will take 14.02 weeks for both the accounts to have the same balance
Bank account balance of Rhiannon = -$253.50
Money deposited by Rhiannon in the bank account each week = $35.80
Bank account balance of Sophie = -$78.25
Money deposited by Sophie in the bank account each week = $23.30
Let the number of weeks it takes to have the same account balance be x, therefore formulating the algebric equation we get:
Bank balance of Rhiannon + Money deposited by her each week*No of weeks it will take for the balance to be equal = Bank balance of Sophie + Money deposited by her each week*No of weeks it will take for the balance to be equal
= -253.5 + 35.8(x) = -78.25 + 23.3(x)
= -175.25 = -12.5(x)
x = 14.02 weeks
Therefore, it will take 14.02 weeks for both the accounts to have the same balance

Whenever we check the number which is greater or lesser by taking the difference between those two numbers we conclude which is greater or lesser.
If the difference between the numbers gets a positive number then the first number is greater than the second.
If the difference between the numbers gets a negative number then the first number is lesser than the second.
If the difference between the numbers gets zero value then the two numbers are equal.

The measure of an angle 2 is 85°.
Given that, ∠6=9x+13 and ∠2=11x-3.
What are corresponding angles?Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line.
As we know, corresponding angles are congruent.
So, ∠6= ∠2
⇒ 9x+13=11x-3
