Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m +n)}[/tex]
[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , [tex]a^{0}[/tex] = 1
given
[tex]3^{-6}[/tex] × ([tex]3^{4}[/tex] ÷ [tex]3^{0}[/tex] )²

Answers
Answer:
[tex]352\ ft ^2[/tex]
Step-by-step explanation:
The formula for the area of a trapezoid is:
[tex]A=\frac{b_1+b_2}{2}*h[/tex]
In this case [tex]b_1 b_2[/tex] represent the two bases of the trapezoid.
We can plug in the given lengths into the equation:
[tex]A=\frac{13+31}{2}*16=\frac{44}{2}*16=22*16=352\ ft^2[/tex]
Answer:
352 ft
Step-by-step explanation:
to do area of a trapezoid you do: (a+b) *h/ 2
a would be 13 b would b 31 and h would be 16 : (13+31) * 16/2
now you will have 44*16/2
now you have 704/2
your final answer is 352

2000 is the y-intercept, it is the amount of money in the account initially.
Exponential functionAn exponential function is in the form:

where a is the initial value of y, b is the multiplier, y, x are variables.
Let y represent the amount in the bank after x years.
Given the function y=2000(0.64)ˣ
Hence:
a = 2000, b = 0.64
0.64 = 1 + x

Equivalent expressions are expressions with same simplified form. Equivalent expressions for the given expression are;
Expression 2: [tex]\ln(a) + 2\ln(b) = \ln(a) + \ln(b^2) = \ln(ab^2)[/tex]Expression 3: [tex]\ln(a^2) + \ln(b^2) - \ln(a) = \ln(a^2b^2/a) = \ln(ab^2)[/tex]Expression 5: [tex]\ln(ab^2)[/tex]What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
What is logarithm and some of its useful properties?When you raise a number with an exponent, there comes a result.
Lets say you get
[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = log_a(c)[/tex]
Some properties of logarithm are:
[tex]log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})\\\\log_a(b^c) = c \times log_a(b)\\\\log_b(b) = 1\\\\ log_a(b) + log_b(c) = log_a(c)[/tex]
Log with base e = 2.71828.... is written as [tex]\ln(x)[/tex] simply.
The expression given is [tex]2\ln(a) + 2\ln(b) - \ln(a)[/tex]
We get its simplified form as
[tex]2\ln(a) + 2\ln(b) - \ln(a) = \ln(a) + \ln(b^2) = \ln(ab^2)[/tex]
Simplifying given expressions:
Expression 1: [tex]\ln(ab^2) - \ln(a) = \ln(ab^2/a) = \ln(b^2)[/tex]This isn't same as simplified form of original

What is the equation of the line that passes through the points (6,6) and (9,8)?
Answers
Answer:
[tex]y=\frac{2}{3}x+2[/tex]
Step-by-step explanation:
The equation for a line is:
y=mx+b
m=slope
b=y-intercept
x,y=(x,y) coordinate pair
Start by finding the slope. The equation for slope is...
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug in the given coordinates into the equation
[tex]Slope=\frac{8-6}{9-6}=\frac{2}{3}[/tex]
Now, we can use the slope and an x,y coordinate pair to find the y-intercept...
y=mx+b
6=2/3(6)+b
6=12/3+b
6=4+b
Subtract 4 from both sides
b=2
Therefore the equation is...
[tex]y=\frac{2}{3}x+2[/tex]

parent function. He wants to write a rule that will make the graph vertically
stretched, reflect it over the x-axis, and shift the graph down. Which of the
following would meet Daniel's needs?
Answers
Using translation concepts, it is found that the function that would meet Daniel's needs is:
g(x) = -cf(x) - b, c > 1, b > 0
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the parent function is f(x).
The transformations are as follows:
Vertical stretch, hence the function has to be multiplied by a constant c that is greater than 1, that is, [tex]g(x) = cf(x), c > 1[/tex].Reflection over the x-axis, hence the function is multiplied by -1, that is, [tex]g(x) = -cf(x), c > 1[/tex].Shift down, hence a constant b is subtracted from the graph, that is, [tex]g(x) = -cf(x) - b, c > 1, b > 0[/tex].You can learn more about translation concepts at https://brainly.com/question/21197885
