The kinetic energy is 1000J.
Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. It is the measure of the work that an object does by virtue of its motion.
Kinetic energy is the product of half the product of mass and the square of the speed.
K.I = 1/2 m v²
Here m = 20kg, v = 10m/s
K.I = 1/2 × 20 × 10²
= 10 ×10²
= 1000
Therefore the kinetic energy is 1000J.

If angle 6 measures 9x+13 and angle 2 measures 11x-3 what is the measurement of angle 2
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
⇒ 13+3=11x-9x
⇒ 16=2x
⇒ x=8
Now, ∠2=11x-3
=11×8-3=85°
Therefore, the measure of an angle 2 is 85°.

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?
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

125 is greater than 23.
Given the question is to explain 125 > 23.
Here we have two numbers which are 125 and 23.
Inequalities:
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.

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.

Given [tex]f(x)=\frac{1}{x+5}[/tex], find the average rate of change of f(x) on the interval
[1,1+h]. Your answer will be an expression involving h.
Pls halp
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

The number of days taken to complete the production of a batch of pens are 22, as calculated by basic algebra.
What is basic algebra?Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra. Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.
Now, According to the question, the factories used all 12 machines in the last days, Also, for the first 8 days, only 9 machines were in use.
Thus, If the factories used all 12 machines, the batch of pens took 20 days to be manufactured.
Hence, the equation formed from the given information by basic algebra is: 20 + 12 - 9(8) / 12

Since p-value > α, H0 is accepted.
The sample standard deviation (S) of LaJolla.res' population is considered to be equal to the sample standard deviation (S) of Pt.Loma.ke's population.
In other words, the difference between the sample standard deviation (S) of the LaJolla.res and Pt.Loma.ke populations is not big enough to be statistically significant.
