(x^(3-6))^2 = (x^-3)^2
x^3*2+x^-6*2 = x^6+x^-12
when the numbers are just next to each other (ex. x²x³) you just ADD the exponents and you get (in this case x^6)when the numbers and exponents are in and out of parentheses (ex. (x³)²) you MULTIPLY the exponents (in this case you get x^6)when you have both, you solve what is IN the parentheses (ex. (x²x³)²) first, making the equation (ex. (x^6)²) and then you multiply the exponent by 2 (ex. (x^12) and get the answer. NOTE - ^ means to the powerThe second from the top, and the second to last expressions should be the answer

n is a positive integer. (i) Explain why n(n - 1) must be an even number.
Answer:
Since the equation is n(n-1) where n is even, (n-1) will result to an odd number and when multiplied the answer with n( an even number), this will result to an EVEN NUMBER. Therefore, in any number that n can substitute, whether even or odd, the answer will always result to an even number

A tape diagram. There are 65 students out of 100 students who ride the bus. There are question mark students out of 800 students who ride the bus. 65% of the 800 students at North High School ride the bus. How many students ride the bus? 100 multiplied by is equal to 800. 65 multiplied by is equal to . out of students ride the bus.
Answer:
answer one is 8
answer two is 8
answer three is 520
answer four is 520
answer five is 800
Step-by-step explanation:
There are 520 students out of 800 ride the bus,
65% of 800 is 520,
100 multiplied by 8 is 800.
What are ratios and proportions?The majority of the explanations for ratios and proportions use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.
Given,
1: There are 65 students out of 100 students who ride the bus. There are question mark students out of 800 students who ride the bus.
let x student out of 800 rides the bus
so both conditions 65/100 and x/800 are in proportions,
65/100 = x/800
x = 800*65/100
x = 520
2: 65% of the 800 students at North High School ride the bus.
65% of 800 = 65/100 x 800
65% of 800 = 520
3: 100 multiplied by is equal to 800.
let x multiplied by 100 is 800
x*100 = 800
x = 800/100
x = 8
Hence 520 students out of 800 ride the bus,
65% of 800 is 520,
100 multiplied by 8 is 800.

A regular hexagon is inscribed in a circle with radius 9 cm. Find the area
Answer:
121.5sqrt(3)
Step-by-step explanation:
Ok, so all regular hexagons are made out of 6 equilateral triangles. If the hexagon is inscribed in the circle, the radius lines up with a side of one of the 6 equilateral triangles and you get 6 equilateral triangles with a side length of 9.
The formula for an equilateral triangle's area is (a/2)^2 * sqrt(3) where a = side length. That means we just plug in 9 to find the area of one of these six triangles. We get 20.25sqrt(3).
We multiply this by 6 (to find the sum of the areas of 6 equilateral triangles) and get 121.5sqrt(3)
The area of the hexagon will be 210.4 cm².
What is a hexagon?The definition of a hexagon in mathematics and geometry is a polygon with six straight sides that is closed in two dimensions.
Given, a circle with a radius of 9 cm. which have a regular hexagon whose all corner touch the circle. If we draw a radius of a circle at the corner of the hexagon. then we get six equilateral triangles.
A regular hexagon is 6 equilateral triangles of side r and area
Area of triangle = (r/2)(√3r/2)
so the total area is
A(hex ) = (6/4) √3r² = 3√3(r²)/2
r = 9m so
A = 210.4m²
Hence the Area of the given hexagon is 210.4 square meters.

Lines AB and CD are parallel. Find the measures of the three angles in triangle ABF.
What is the angle measurement for A, B, and F. (Make sure they are degrees)
Can you help me with this math question?
A = 42°
B= 23°
F = 115°
Step-by-step explanation:
The required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.
What are Alternate Interior Angles?Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines
Given that Lines AB and CD are parallel.
To determine the measures of the three angles in triangle ABF.
For finding ∠F,
∠CDF = 180° - 157° = 23°
∠F = 180° - ∠C - ∠CDF
∠F = 180° - 42° - 23°
∠F = 115°
However, if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
So ∠A = ∠CDF = 23°
And ∠B = ∠C = 42°
Thus, the required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.

The mean and standard deviation for number of battery crimes in the U.S. from 1985 to 2000 are X = 326,845 and sx = 27,569. The mean and standard deviation for number of property crimes in the U.S. for the same time period are y = 634,235 and Sy = 42,268. The correlation coefficient is r = 0.92. Find the equation for the least- squares regression line for number of property crimes compared with number of battery crimes.
A: y = 1.41 + 173,214.37x
B: y = 173,214.37 + 1.41x
C: y = 421,052.69 + 0.65x
D: y = 0.65 + 421,052.69x
E: Unable to determine the equation
Answer:
The correct answer is: A
Step-by-step explanation:
The value of the slope and intercept is:
=0.92(42268/27569)
=1.410518
a=y-bx
=634235-1.410518×326845
=173214.3716
The eququation for the least-square regression line is:
y=173214.3716 + 1.4105518x
Round to the 2 decimal place:
=173,214.37 +1.41x
The equation for the least squares regression line for number of property crimes compared with number of battery crimes is (b) y = 141x + 173214.37
How to determine the least square regression equation?The given parameters are:
Mean x, μ = 326,845 Standard deviation of x, σ = 27,569Mean y, μ = 634,235 Standard deviation of y, σ = 42,268Correlation coefficient, r = 0.92Calculate the slope (m) using:
m = r * Sy/Sx
This gives
m = 0.92 * 42268/27569
Evaluate
m =1.41051761036
Approximate
m = 1.41
The y-intercept (c) is calculated using:
c = μy -m * μx
So, we have:
c = 634235 - 1.41051761036 * 326845
Evaluate
c = 173214.371642
Approximate
c =173214.37
The least-square regression line equation is represented as:
y = mx + c
So, we have:
y = 141x + 173214.37
Hence, the equation for the least squares regression line for number of property crimes compared with number of battery crimes is (b) y = 141x + 173214.37
