Answer:
1. z^2
2. 14z
Step-by-step explanation:
We know that (a^m)^n = a^(mn) = (a^n) ^mWe also know that (a^m)(a^n) = a^(m+n)
36 can be written as 6^2 and here 36^(500) can be written as (6^2)^500 which also can be written as (6^500)^2 and as already it is mentioned that 6^500 as z we can write the above as z^22. 8 x 6^500 = 8z
And we can also write 6^(501) as 6^(500+1) which is equivalent to 6(6^500) which is 6z.
From the above we can make sure that the question is the sum of the above which is 8z + 6z = 14z.
a block of wood has a mass of 3.5 kilogram. the wood has density 0.065 kg/m3
work out the volume of the block of wood
Step-by-step explanation:
Given :-
A block of wood has a mass of 3.5 kilogram. The wood has density 0.065 kg/m³.And we need to find out the volume of the wood. Density , volume and mass are related as ,
Density :-
Mass per unit Volume .\(\implies\rm Density =\dfrac{Mass}{Volume}\)
Substitute the respective values :-
\(\implies\rm Density =\dfrac{Mass}{Volume}\\\\\rm\implies 0.065 kg/m^3=\dfrac{3.5kg}{V}\\\\\rm\implies Volume = \dfrac{3.5kg}{0.065 kg/m^3}\\\\\implies\boxed{\red{\rm Volume = 53.84 m^3}}\)

solve the system of equations y = 2x - 5; y = -2x + 3
Answer:
Solving gives us the result, x = 2, y = -1
Step-by-step explanation:
The system of equations is,
y = 2x-5
y=-2x+3
equating the two equations, we get,
(since y = y)
\(2x-5 = -2x + 3\\4x -5 = 3\\4x = 3+5\\4x=8\\x=8/4\\x=2\)
and then since y = 2x-5
\(y=2(2)-5\\y=-1\)
so, x =2, y = -1

A number line goes from negative 10 to positive 10. An open circle appears at positive 1. The number line is shaded from positive 1 toward negative 10.
Answer:
the solution set of inequality 2.9 (x + 8) less-than 26.1 is \(x<1\)
Option D is correct.
Step-by-step explanation:
We need to find the graph that shows the solution set of the inequality 2.9 (x + 8) less-than 26.1
First we will solve the inequality to find value of x
\(2.9 (x + 8) <26.1\)
Divide both sides by 2.9
\(\frac{2.9 (x + 8)}{2.9} < \frac{26.1}{2.9} \\x+8 < 9\)
Subtract both sides by -8
\(x+8-8<9-8\\x<1\)
So, the solution set of inequality 2.9 (x + 8) less-than 26.1 is \(x<1\)
The graph would be:
A number line goes from negative 10 to positive 10. An open circle appears at positive 1. The number line is shaded from positive 1 toward negative 10.
Option D is correct.

C) x-intercept is 2 and y-intercept is 4
D) x- intercept is 2 and y-intercept is -4
Look at the image!!!!
Answer:
(see explanation below)
Step-by-step explanation:
The x-intercept is where the line intersects with the x-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the x-axis at (-2, 0). Therefore, the x-intercept is -2.
The y-intercept is where the line intersects with the y-axis. If you look at the given line in the coordinate plane, you can see that the line intersects the y-axis at (0, 4). Therefore, the y-intercept (also represented by the variable b) is 4.
Peter is going to visit 5 cities this summer. He will choose from 7 different cities, and the order in which he visits the cities does not matter. How many different city combinations are possible for the summer traveling?
There are 21 different city combinations possible for Peter's summer traveling.
To determine the number of different city combinations possible for Peter's summer traveling, we need to calculate the number of combinations of choosing 5 cities out of the 7 available cities.
Since the order in which he visits the cities does not matter, we are dealing with combinations rather than permutations.
The formula to calculate the number of combinations is given by the binomial coefficient, also known as "n choose k," denoted as C(n, k) or (nCk).
In this case, we have 7 cities to choose from, and Peter will visit 5 cities. Thus, we can calculate the number of city combinations as follows:
C(7, 5) = 7! / (5! * (7-5)!)
= 7! / (5! * 2!)
= (7 * 6 * 5!) / (5! * 2)
= (7 * 6) / 2
= 42 / 2
= 21

Why does cube root 7 equal 7 to the 1/3 power
Answer:
Step-by-step explanation:
Here's how you convert:
\(\sqrt[n]{x^m}=x^{\frac{m}{n}\) The little number outside the radical, called the index, serves as the denominator in the rational power, and the power on the x inside the radical serves as the numerator in the rational power on the x.
A couple of examples:
\(\sqrt[3]{x^4}=x^{\frac{4}{3}\)

mrs wu spent 1/6 of her on a dress and 2 blouses. the dress cost 3 times as much as each blouse. mrs wu spent 3/4 of her remaining money on a watch. she spent $220.50 more on the watch than on the dress.
Mrs. Wu initially had $1062.40.
Let's break down the given information step by step:
1. Mrs. Wu spent 1/6 of her money on a dress and 2 blouses.
Let's assume Mrs. Wu's total money is represented by the variable M. She spent 1/6 of M on the dress, which means she spent (1/6)M on the dress and the same amount on two blouses.
2. The dress cost 3 times as much as each blouse.
Let's assume the cost of each blouse is represented by the variable B. Therefore, the cost of the dress would be 3B.
3. Mrs. Wu spent 3/4 of her remaining money on a watch.
After spending on the dress and blouses, Mrs. Wu has (M - (1/6)M) = (5/6)M remaining. She spent 3/4 of this remaining money on a watch, which is (3/4) * (5/6)M = (15/24)M.
4. She spent $220.50 more on the watch than on the dress.
The amount spent on the watch is (15/24)M, and the amount spent on the dress is (1/6)M. The difference between these amounts is $220.50.
To find the value of M, we can set up an equation:
(15/24)M - (1/6)M = $220.50
Simplifying the equation:
(15/24 - 1/6)M = $220.50
(5/24)M = $220.50
Multiplying both sides by (24/5):
M = $220.50 * (24/5)
M = $1062.40

If the function y=sin(x) is transformed to y = sin(2x), how does the graph change?
It is stretched vertically.
It is compressed vertically.
It is stretched horizontally.
It is compressed horizontally..
Step-by-step explanation:
The transformation y = sin(2x) affects the graph of y = sin(x) by compressing it horizontally.
The function y = sin(2x) has a coefficient of 2 in front of the x variable. This means that for every x value in the original function, the transformed function will have half the x value.
To see the effect of this transformation, let's compare the graphs of y = sin(x) and y = sin(2x) by plotting some points:
For y = sin(x):
x = 0, y = 0
x = π/2, y = 1
x = π, y = 0
x = 3π/2, y = -1
x = 2π, y = 0
For y = sin(2x):
x = 0, y = 0
x = π/2, y = 0
x = π, y = 0
x = 3π/2, y = 0
x = 2π, y = 0
As you can see, the y-values of the transformed function remain the same as the original function at every x-value, while the x-values of the transformed function are compressed by a factor of 2. This means that the graph of y = sin(2x) appears narrower or more "squeezed" horizontally compared to y = sin(x).
Therefore, the correct statement is: It is compressed horizontally.

A spinner is divided into three sections: red, blue, and green. The red section is 2/5 of the area of the spinner. The blue section is 1/2 of the area of the spinner. Give the probability for each outcome. Express your answers as fractions.
Probability of red = \(\frac{4}{10}\) , blue = \(\frac{5}{10}\) , green = \(\frac{1}{10}\).
Meaning of probability :
Probability is calculation of how likely some event will happen. Whenever we are not sure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are going to happen.
The analysis of events governed by probability is called statistics.
According to the given information :
Red section = \(\frac{2}{5}\)
multiply numerator and denominator by \(2\) we get
Red section = \(\frac{4}{10}\)
Blue section = \(\frac{1}{2}\)
multiply numerator and denominator by \(5\) we get
Blue section = \(\frac{5}{10}\)
Green section = \(1\)- Red section - Blue section
Green section =\(1-\frac{4}{10} -\frac{5}{10}\)
Green section = \(\frac{1}{10}\)
Therefore Probability of red = \(\frac{4}{10}\) , blue = \(\frac{5}{10}\) , green = \(\frac{1}{10}\).
