Answer:
[tex]\frac{3^{n} }{3^{2(n-1)} }[/tex]
Step-by-step explanation:
3²⁻ⁿ is the simplification of 3ⁿ/9ⁿ⁻¹ in powers of 3.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 3ⁿ/9ⁿ⁻¹
three power n divided by nine power n minus one.
To express to the power of 2, we have few properties of exponentials.
aˣ/aⁿ=aˣ⁻ⁿ
aˣ.aⁿ=aˣ⁺ⁿ
The given expression is
3ⁿ/9ⁿ⁻¹
3ⁿ/(3²)ⁿ⁻¹
3ⁿ/3²ⁿ⁻²
3ⁿ.3⁻²ⁿ⁺²
When bases are same then we will add the powers
3ⁿ⁻²ⁿ⁺²
3²⁻ⁿ
Hence 3²⁻ⁿ is the simplification of 3ⁿ/9ⁿ⁻¹ in powers of 3.

Only hash channel catfish typically was about 0.06 g during the first six weeks of life at weight increase about 10% each day right a exponential model for the weight how much will the catfish gain weight after six weeks
Answer:
3.225 gram
Step-by-step explanation:
Given that :
Initial weight = 0.06g
Rate of increase, r = 10% = 0.1 per day
Weight gain after 6 weeks
For an exponential model. f(x)
f(x) = a(1 + r)^x
Where ; a = initial amount ; r = growth rate ; x = period
Our model becomes :
f(x) : 0.06(1 + 0.1)^x
f(x) = 0.06(1.1)^x
Number of days in 6 weeks = 6*7 = 42 = x
f(42) : 0.06(1.1)^42
= 3.285 gram
Hence, weight gain after 6 weeks :
(3.285 - 0.06) g = 3.225 gram

Determine if the side lengths given form a triangle. Justify your response. 6.4 mm, 12.9 mm, 14.2 mm
Answer:
Step-by-step explanation: Yes I think since if you add 12.4 and 6.4 your answer is more then 14.2 so yes it is possible
Answer:
Yes, it does form a triangle
Step-by-step explanation:
According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.

1. square with a side 2.4 m in length find the perimeter and area
2. rectangle with length (x+3) and width 7
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle?
Answer:
1= Perimeter =9.6
Area = 5.76m^2
Answer:
find the perimeter and area:
1. square with a side 2.4 m in length find the perimeter and area
answer:
length [l]=2.4m
area of square=l²=2.4²=5.76m²
perimeter of square=4l=4×2.4=9.6m
2. rectangle with length (x+3) and width 7
answer:
length [l]=x+3
Breadth [b]=7
perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20
area of rectangle=l×b=(x+3)×7=7x+21
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle.
answer:
the term for the perimeter of a circle=2πr (when radius is given ) and πd (when diameter Is given)
find the length of the arc intercepted by a central angle of 1.5 radians in a circle of radius 9 cm.
Answer:
13.5 cm
Step-by-step explanation:
The length of an arc depends on the radius of a circle and the central angle θ. We know that for the angle equal to 360 degrees (2π), and the arc length is equal to circumference. Hence, as the proportion between angle and arc length is constant, we can say that:
L/θ = C/2π (C = Circumference = 2πr)
L/θ = 2πr/2π,
L/θ = r,
L = r*θ = 9 cm * 1.5 = 13.5 cm

Step-by-step explanation:
Calculate the sums within the brackets first and then multiplication, as stated by the BOMDAS rule.
B = Brackets
O = ?
M = Multiplication
D = Division
A = Addition
S = Substitution
(- 6 + 4) = -2
(5 + 9) = 14

Answer: 5.81%
Step-by-step explanation: Delta Math
A = 17700. P = 9900. t = 10
17700 = 9900e^r(10)
17700/9900 = 9900e^10r/9900
1.7878788 = e^10r
In(1.7878788) = In(e^10r)
In(1.7878788) = 10r
In(1.7878788)/10 = 10r/10
0.058103 = r
5.8103% = r
r = 5.81%

The scale factor is 2. Then the value of the variable 'x' is 1 cm.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.
The scale factor is given as,
SF = 14 / 7
SF = 2
Then the value of the variable 'x' is calculated as,
x = 8 / SF
x = 8 / 2
x = 4 cm
The scale factor is 2. Then the value of the variable 'x' is 1 cm.
