equivalent answers for 64 to the power of 2/3
Answer:
16
Step-by-step explanation:
Dealing with a fraction exponent on hand can be converted by using the fractional exponents rule where the fraction exponent is converted to something like this:
[tex]64^\frac{2}{3} = \sqrt[3]{64^{2}}\\[/tex]
As you can see, the denominator of the fractional exponent is now the index of the radical. Here is a guide to know what goes where.
[tex]64^\frac{x}{y} = \sqrt[y]{64^{x}}[/tex]
Both the original problem (64^2/3) and the converted formula can be put into a calculator.
Simplify (if you want to)
[tex]\sqrt[3]{64^{2}}\\\sqrt[3]{4096}\\16[/tex]
64 to the power of 2/3 is 16.

What is the equation for a circle with the center, (0,0) and a radius of 4?
Answer:
(X-x0)^2 +(y-y0)^2= r^2
R=4
R^2=16
(X-0)^2+(y-0)^2=16
2) (19,8) (3,4)
Find the slope?
Answer:
1/4
Step-by-step explanation:
the equation for slope is (y2 - y1) / (x2 - x1)
so the equation is (4-8)/(3-19)
= -4/-16
= 4/16
= 1/4, therefore, the slope is 1/4 or 0.25 as a decimal

Which of these relations is a function?
I’m I correct??
Answer:
the first one on the bottom
Step-by-step explanation:
There is a little trick to find out if it is a function or not. This trick is called the vertical line test. if you can scan the figure with a virtual line and it does not touch more than one side of the figure at one time then it is a function. if it touches more than one side or line of the figure it is not a function.
What is the answer?
Answer:
clockwise
Q= (5,-2)
R= (-1,-3)
S= (0,0)
T= (3,-2)
counterclockwise
Q= (-5,2)
R= (1,3)
S= (0,0)
T= (-3,-2)
Step-by-step explanation:
this might not be right im a little rusty on my transformations but here goes nothing.
i dont know if this is a clockwise or a counter clockwise rotation so ill do both options.
clockwise (x,y) - (y,-x)
q=(2,5) - (5,-2)
r=(3,-1) - (-1,-3)
s=(0,0) - (0,0)
t=(-2,3) - (3,2)
counterclockwise (x,y) - (-y,x)
q=(2,5) - (-5,2)
r=(3,-1) - (1,3)
s=(0,0) - (0,0)
t=(-2,3) - (-3,-2)
which shows the use of the associative property?
Answer:
The correct answer is Option 2:
[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]
Step-by-step explanation:
Associative property consists of three quantities. Associative property for addition states that the result of adding three numbers will be same no matter what the order of addition is.
Let a,b and c be three numbers
Then associative property can be stated as:
[tex]a+(b+c) = (a+b)+c[/tex]
Now looking at the options it can be observed that the following choice shows the associative property
[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]
Hence,
The correct answer is Option 2:
[tex]7+(\frac{1}{5}+n) = (7+\frac{1}{5})+n[/tex]

using the equation y=-6x+1: if you choose -2 as the input ,what will be the output
Answer: 13
Step-by-step explanation: you substitute x for -2 because the input is known as x. The output is known as y; solving the new equation y=-6(-2)+1 you will get y=12+1 then y=13
write an equation in slope-intercept form of the line that passes through the given points (-4,-2) (8,-2)
Answer:
y=-2
Step-by-step explanation:
First, find the slope using the slope formula: m=y2-y1/x2-x1
Plug the numbers into the equation and get 0
Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)
y+2=0(x+4)
Distribute and simplify to get the final answer.
y+2=0+0
y=-2
Prove step by step that 5^20-5^19 is an even number with out using a calculator Please can you tell me the steps and why?
9514 1404 393
Answer:
factor out 5^19
Step-by-step explanation:
a) Reason from parity:
both 5^20 and 5^19 are products with only odd numbers (5) as factors. Hence each is an odd number. The difference of odd numbers is always even.
__
b) Factor:
5^20 -5^19 = 5^19(5 -1) = 5^19×4
This product has an even factor (4), so is even.
Which statement is true about the graphs of the two lines y=-x+2 and y=-x- ?
O The lines are perpendicular to each other because - and - are opposite reciprocals of each other.
The lines are perpendicular to each other because 2 and - 1 are opposite reciprocals of each other.
O The lines are neither parallel nor perpendicular to each other because - and are not opposite reciprocals
of each other.
The lines are neither parallel nor perpendicular to each other because 2 and - 3 are not opposite reciprocals of
each other.
Answer:
The correct option is Option C
Step-by-step explanation:
We are given the lines: [tex]y=-\frac{4}{5}x+2 \ and \ \ y=-\frac{5}{4}x-\frac{1}{2}[/tex]
The lines are perpendicular if they have opposite slopes i,e [tex]m_1=-\frac{1}{m_2}[/tex]
In line 1 the slope is [tex]-\frac{4}{5}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-4/5)
In line 2 the slope is [tex]-\frac{5}{4}[/tex] (Comparing with slope-intercept form [tex]y=mx+b[/tex] we get the value of m=-5/4)
The opposite reciprocal of -4/5 is 5/4
So, the lines are not perpendicular as their slopes are not opposite reciprocal of each other.
If the lines are parallel there slope must be same. Hence lines are not parallel as well.
So, The correct option is Option C
Answer:
c

Which table has a constant of proportionality between yyy and xxx of 0.30.30, point, 3?
Answer:
Answer
Step-by-step explanation:
The answer is C
You would do 1.2 ÷ 4 which is 0.3
2.4 ÷ 8 is 0.3
3.9 ÷ 18 is 0.3
A is wrong because the constant of proportionality is 0.33333
B is wrong because the constant of proportionality is 0.6

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.
How to solve:
First use the formula: C = 3.14dReplace the d value with 30 and solve the equation:C = 3.14 x 30 ⇒ 94.2477796077
Then solve the equation again but 21 as the d value:C = 3.14 x 21 ⇒ 65.9734457254
Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8If eight trash bags last for thirty days then 28 trash bags will last for how long

Answer:
The rate is 15 minutes per meter.
Step-by-step explanation:
It takes 9 minutes to fill a depth of meters.
Filling meters take 9 minutes time.
Filling 3 meters of the aquarium takes = 45 minutes time (Multiplying by 5 both the numbers).
In order to fill 1 meter of the aquarium it will take minutes (Dividing by 3 both the numerical values).
===================================================
Work Shown:
8 minutes = (2/5) meters
5*(8 minutes) = 5*( (2/5) meters )
40 minutes = 2 meters
40/2 minutes = 2/2 meters
20 minutes = 1 meter
The unit rate in minutes per meter is 20 minutes per meter.
In other words, it takes 20 minutes to raise the level 1 meter.
