Answer: x8 i really don't know if it is correct tell me plz
Step-by-step explanation:
The expression (x²)⁴ without exponents can be written as x × x × x × x × x × x × x × x.
The given expression is (x²)⁴.
It is known that the power rule of exponents states that:
(xᵃ)ᵇ = xᵃᵇ
Here, a = 2 and b = 4.
So using the power rule,
(x²)⁴ = x²⁽⁴⁾
= x⁸
Now, it is known that exponents are actually the multiplication of the number with the same number again and again.
Here x is multiplied by itself 8 times.
So the expression can be written as:
x × x × x × x × x × x × x × x.

1. Simplify the expression: 2(5a−4a)+6a =
2. −2(x−9)=44
Answer:
1. 8a
2. -13
Step-by-step explanation:
1. 2(5a − 4a) + 6a
= 10a - 8a + 6a
= 2a + 6a
= 8a
2. −2(x − 9) = 44
-2x + 18 = 44
-2x = 44 - 18
-2x = 26
x = 26/-2
x = -13
1) open the bracket
10a-8a+6a
2a+6a
8a
2) open the bracket
-2x+18=44. Remember - × - = +
Collect like terms
-2x=44-18
-2x=26
Divide both side by -2
x=-13

Find THe QUADRATIC equation 100 POINTS PLS HELP: (0,6),(1,6.5),(2,8),(3,10.5),(4,14)
Answer:
y = 1/2x^2 +6
Step-by-step explanation:
The quadratic regression function of a calculator or spreadsheet is useful for this purpose. It shows you the equation is ...
y = 1/2x^2 +6
_____
Alternate solution
Another way to approach this is to look at first and second differences of the y-values.
Sequence of y-values:
6, 6.5, 8, 10.5, 14
Sequence of first differences:
0.5, 1.5, 2.5, 3.5
Sequence of second differences:
1, 1, 1, 1
The leading coefficient of the quadratic is half the value of the second differences: a = 1/2. The constant in the quadratic is the y-intercept, the value when x=0. The first point gives that as 6.
__
Now, you can check some other point to see what the linear term coefficient might be:
y = 1/2x^2 +bx +6
For x=2, this is ...
8 = 1/2(2^2) +b(2) +6 = 8 +2b . . . . . substitute (x, y) = (2, 8), simplify
0 = 2b ⇒ b = 0
Then the quadratic is ...
y = 1/2x^2 +6
_____
Additional comment
You may not know the relation between second differences and the leading coefficient. The most general way to solve this is to write three equations in the unknown coefficients. Since y has integer values for x=0, 2, 4, you may want to use these. For (x, y) = (0, 6), (2, 8), and (4, 14), you have ...
y = ax² +bx +c
6 = 0a +0b +c8 = a(2²) +b(2) +c14 = a(4²) +b(4) +cAfter finding c=6 in the first equation, you have two equations in 2 unknowns:
2 = 4a +2b ⇒ 2a +b = 18 = 16a +4b ⇒ 4a +b = 2The solution to these is a=1/2, b=0, as above.

Answer:
y=4x
Step-by-step explanation:
In a proportional relationship, two values always have the same ratio to each other. This means that when we look at the equation of a line, y=mx+b, where m=slope and b=how much more plus the slope y is, there cannot be a "b" value.
An example of this is:
If the slope is 3,
y=3x
If x=2, y=6
If x=5, y=15
We can see that for every pair of coordinates, the ratio (5) between x and y remain the same.
y cannot have anything added to i (ex: y=3x+1), otherwise the ratio would change.
Ex:
If the equation is y=3x+1,
If x=1, y=4
If x=2, y=7
We can see that the ratios between the two numbers (1/4, 2/7) are not the same.
In this problem, the only equation without "b" is y=4x. Therefore, the answer is y=4x.

Find the Mean for 15 points
Hello there!
Mean is the average of a set of numbers.
To find the mean, we have to add all the numbers and divide by how many there are.
Add: 68 + 55 + 72
Equals: 195
However, we have to find the mean of the 3 rounds in the 4th fight.
Add: 55 + 42 + 40
Equals: 137
Then, we divide it by 3.
Equals: 45.7
Next, add it to 195 since it was of 3 separate fights.
195 + 45.7 = 242.5
Lastly, divide it by 6 since there were 6 numbers in the data set.
Divide: 242.5/6
Equals: 40.42
Therefore, our mean for the 4 fights is 40.42 or 40.
There's another answer that we can get by simply adding up all the numbers and dividing it by 6.
Add: 68 + 55 + 72 + 55 + 42 + 40
Equals: 332
Then, we divide by 6.
Divide: 332/6
Equals: 55.33
So, yeah 55.33 would be the better mean then 40 since 40 makes it seem very low.

Mean x¯¯¯ 55.333333333333

3x-2y
-2y+5x
x?y2
(-2y+5x) (3x-2y)
(-2y+5x) (3x-2y)
x?y?
Answer:
Step-by-step explanation:
Answer:
(-2y+5x) / (3x - 2y)
Step-by-step explanation:
If we write this sentence, we have:
((-2/x) + (5/y)) / ((3/y) - (2/x))
If we do LCM in the denominators of each fraction, we have:
((-2y+5x)/xy) / ((3x - 2y)/xy)
We can cut the 'xy' in the numerator and denominator of the whole fraction:
(-2y+5x) / (3x - 2y)
The final expression we have is (-2y+5x) / (3x - 2y)
The sum of two numbers is 73. When the smaller number is subtracted from twice the greater number, the result is 50. Find the numbers. Please use a let statment and an algebraic solution. Thanks! :)
Answer:
The big number is 41 and the small number is 32.
Step-by-step explanation:
b + s = 73
2b - s = 50 Add these equations together
3b = 123 Divide both sides by 3
b = 41
Now plug this into the first equation to find s
41 + s = 73
-41 - 41
s = 32

Which is the measure of the reference angle for 227?
a. 35
b. 23
c. 47
d. 43
Answer:
c
Step-by-step explanation:
227° is in the third quadrant. To find the reference angle subtract 180° from it.
reference angle = 227° - 180° = 47° → c
To avoid a storm, a pilot of a vintage biplane flies up 2,500 feet, but stays below 32,000 feet. Write and solve an inequality to find the maximum original altitude of the plane.
a + 2,500 > 32,000; a > 34,500
a + 2,500 < 32,000; a < 29,500
a + 2,500 < 32,000; a < 34,500
a + 2,500 > 32,000; a > 29,500
Answer:
a + 2,500 < 32,000; a < 29,500
Step-by-step explanation:
This shows the 2,500 can be adapted to become less than 29,500 in additional measure when flying.
As 2,500+ 29,500 = 32,000
The a+2,500<32,000 is also correct as this shows less than and confirms that the biplane stays below 32,000.
A man is able to run an arc of 150° along a circular track, whose radius is 150 ft. How far did the man run?
Answer:
392.5 ft
Step-by-step explanation:
First, let's find the circumference of the track. This is 2 * 3.14 * 150 = 942 ft. 150° is 5 / 12 of 360° (the full circle) so that means that the minor arc it forms (which is also the arc the man ran) is 5/12 of the circumference. This means that the answer is 5/12 * 942 = 392.5 ft. Hope this helps!
Answer:
Step-by-step explanation:
length of the arc = angle/360 * 2 * pi * r
150/360 * 2 * 22/7 * 150
393 ft
Archie plays a word board game. He places 98
lettered tiles and 2 blank tiles in a bag. Players
will draw tiles from the bag one at a time
without looking.
What is the probability that the first tile drawn
will be a blank tile? Labeled with a letter? A
vowel? A consonant?
Select each type of tile to see its probability.
Answer:
blank: 0.02
lettered: 0.98
vowel: 0.42
consonant: 0.56
Step-by-step explanation:
In the figure attached, the number of tiles of each letter are shown.
number of blank outcomes: 2
number of lettered outcomes: 98
number of vowel outcomes: 9 + 12 + 9 + 8 + 4 = 42
number of consonant outcomes: 98 - 42 = 56
Total number of outcomes: 100
Probability that first tile drawn is a blank tile: 2/100 = 0.02
Probability that first tile drawn is labeled with a letter: 98/100 = 0.98
Probability that first tile drawn is a vowel: 42/100 = 0.42
Probability that first tile drawn is a consonant: 56/100 = 0.56

you could either substitute (0,-4) or (1,2) into the equationn
y = 6x + b
-4 = 6(0) +b
-4 = 0+b
b = -4
or
y = 6x +b
2 = 6(1) + b
2= 6 +b
b= -4
Answer:
-4
Step-by-step explanation:
Y = mx+b is the slope intercept form of the equation
where m is the slope and b is the y intercept
The y intercept is where the line crosses the y axis
It is the value where x is zero
(0,-4) the x value is zero so the y intercept is -4

Also set the height of the pyramid to the same side length as the cube. Note the volumes of the cube and the pyramid. Record the volumes for a few sets of heights and bases, and then calculate the ratio of the volumes. Be sure the dimensions for the cube and the pyramid are the same in each set. (You might see some discrepancies in the tool due to rounding of decimals.) Round your calculations for the ratio to the hundredths place. The first one has been done for you.
