what is the coefficient of a^8b^2 in the expansion (1/3a^2 - 4b)^6
Step-by-step explanation:
(1/3a^2-4b)^6 for such an expansion the general term is
[tex]tr + 1 = \binom{6}{r} \times ( \frac{1}{3} {a}^{2} ) ^{6 - r} \times (4b)^{r} [/tex]
we want b^2 so r=2
so the formula transform to:
C6,2*(1/3)^4*a^8*4^2*b^2 so the coefficient of a^8b^2 is
(6*5/2*1)*(1/3^4)*4^2=
6*5*4*4/2*3*3*3*3=16*5/27=80/27

What is x
Answer:
x = 109°
Step-by-step explanation:
Angle x lies outside of line d, and is also positioned just on the side of line a that is opposite to the side of line a occupied by angle 109°.
Therefore, angle x and the angle measure of 109° are alternate exterior angles.
Alternate exterior angles are congruent.
x = 109°.

Each day Marisa runs the same distance. She ran 35 miles in the last 5 days. What is the unit rate?
Answer:
7 miles
Step-by-step explanation:
As, we will take unit rate as "x"
So, for one day = x distance
For 5 days = 5(x)
For 5 days she covered 35 miles
So therefore,
5(x) = 35 miles
X= 35/5
X=7 miles
For a day= 7 miles are covered

The scale of a map says that 2 cm represents 10 km. What is the actual number of kilometers that is represented by 6 centimeters on the map?
Answer:
6 times 10 to the minus 5
6 cm on the map represents 30 kilometers in reality, with a scale of 2 cm representing 10 km.
In the given map, the scale is 2 cm represents 10 km.
Each centimeter on the map represents 5 km (10 km divided by 2 cm).
We can use the scale of the map, which states that 2 cm represents 10 km, to determine the precise number of kilometers that 6 centimeters on the map represent.
If 2 cm represents 10 km, then 1 cm represents 10 km / 2 cm = 5 km.
6 centimeters on the map represent 6 cm × 5 km/cm = 30 kilometers in reality.

What’s meaning of x in math
Answer:
variable
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Explain how to use the distributive property to find the product 3 x 4 1/5
Answer:
12.6
Step-by-step explanation:
The answer is 12.6 and here is the explanation of using the Distributive Property. Because we are multiplying a whole number by a mixed number, we have to multiply the whole number by the whole number in the mixed number and then multiply the whole number by the fraction. In this case, we have 3 x 4 1/5. We multiply 3x4=12 first, and then we multiply 3x1/5 to get 0.6. 12+0.6=12.6. Hope it helps!
The product of 3 x [tex]4\frac{1}{5}[/tex] is 12.6.
What is Number system?A number system is defined as a system of writing to express numbers.
The distributive property tells us how to solve expressions in the form of a(b + c).
The given expression is 3 x [tex]4\frac{1}{5}[/tex]
This expression can be written as 3(4+1/5)
The value of 1/5 is 0.2
3(4+0.2)
Now add 4 and 0.2
3(4.2)
Now multiply 3 and 4.2
12.6
Hence, the product of 3 x [tex]4\frac{1}{5}[/tex] is 12.6.

Helpp meee pleaseeeeeeeeeee !!!!
Step-by-step explanation:
since the domain of the function is given, you just have to plug in the numbers to the function:
13x - x²
it's basically asking: if x was any of the numbers in the given domain, what would it be the answer be?
for example:
I'll solve for -2 and you can do the rest.
13 • -2 -(-2 ²) =
13 • 2 + 4 =
26 + 4 = 30
so the range for -2 would be 30

Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 mile route every morning. His goal is to run at least 6 miles
by the end of the week. Which inequality represents the least number of days after Monday that Joseph needs to run to reach his goal?
Sine he runs 2 miles on Monday, we already have a +2.
Then, he runs by a constant rate of 1, which is the constant rate of change per day.
Let x represent the number of days he runs and y the total amount of miles he runs. Now, the equation is y = x + 2
However, he needs to run at least 6 miles. At least means greater than or equal to. The values for y can be greater than 6, or equal to 6.
y ≥ 6
y = x + 2
Now substitute x + 2 for y.
x + 2 ≥ 6
Subtract 2.
x ≥ 4
This is the inequality. He has to run for at least 4 days.
9 hundreds equals how many tens
Answer:
90 tens
Step-by-step explanation:
900 = 10x
Variable x refers to how many 10's are needed to equal 900
To solve for this, divide both sides of the equation by 10
900 ÷ 10 = 10x ÷ 10
90 = 1x
90 = x
It will take 90 tens to equal 900

If f (x) = one-ninth x minus 2, what is f>1(x)
Answer: f-1(x) = 9x + 18.
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
Multiply through by 9 to clear the fraction
9y + 18 = x
Change y back into terms of x
(x) = 9x + 18
Answer:
Answer: f-1(x) = 9x + 18.
