The mass of a certain grain of sand is 0.009 grams and the mass of the salt is 0.0006. Use scientific notation to compare the masses of the salt and sand grains. Show your work.
Pls Hurry !!!!!!!
i will give 100 points
Answers
Answer: The mass of the sand is greater than the mass of the salt.
Step-by-step explanation: Scientific notation is a way of writing numbers that are very large or very small. It is written in the form a x 10^b, where a is a number between 1 and 10 and b is an integer. For example, 300 can be written as 3 x 10^2 in scientific notation.
To compare the masses of the salt and sand grains using scientific notation, we first need to write them in scientific notation. The mass of the salt is 0.0006 grams, which can be written as 6 x 10^-4 grams. The mass of the sand is 0.009 grams, which can be written as 9 x 10^-3 grams.
Next, we compare the exponents. Since -3 < -4, we know that 9 x 10^-3 > 6 x 10^-4. This means that the mass of the sand is greater than the mass of the salt.
Hope this helps, and have a great day!

sketch the region enclosed by the given curves. (a graphing calculator is recommended.) y = 4 − x2, y = 0
Answers
The region enclosed by the curves y = 4 - \(x^{2}\) and y = 0 can be sketched as follows:
Consider the equation y = 4 - \(x^{2}\).
This equation represents a downward-opening parabola centered at the origin with a vertex at (0, 4).
As x increases or decreases, the value of y decreases, resulting in a curve that opens downwards.
the points of intersection between the curves y = 4 - \(x^{2}\) and y = 0. Setting
y = 0 in the equation y = 4 - \(x^{2}\), we can solve for x:
0 = 4 - \(x^{2}\)
\(x^{2}\) = 4
x = ±2
So, the points of intersection are (-2, 0) and (2, 0).
By plotting the parabola y = 4 - \(x^{2}\) and the x-axis, we can see that the region enclosed by the curves is a symmetric portion of the parabola below the x-axis, between x = -2 and x = 2.

Answers
The total materials cost before sales tax is $297.21.
How the total materials cost is determined:The total materials cost is the result of the addition of the total cost of posts, wire mesh, gate, and staples, as follows.
The length of the rectangular space = 6 meters
The width of the space = 10.5 meters'
The perimeter of the space = 33 meters [2(6 + 10.5)]
The space between posts = 1.5 meters
The number of posts = 22 (33 ÷ 1.5)
The cost per post = $2.69
a) The cost of the posts = $59.18 ($2.69 x 22)
The cost of wire mesh:
Cost per meter = $5.96
The number of meters of wire mesh = 33 meters
b) Total cost of the wire mesh = $196.68 ($5.96 x 33)
c) Cost of the gate = $25.39
Cost of Staples:
The number of staples per post = 7
The total number of staples required = 154 (22 x 7)
The number of boxes of staples = 4
The cost per box = $3.99
d) The total cost of staples = $15.96 (4 x $3.99)

Which number sentence states that x is at most 50?
A. x < 50
B. x < 50
C. x = 50
D.x > 50
E. x > 50
idk this one is kind of confusing me
Answers
Answer:
its A & B, x<50
Step-by-step explanation:
atmost means till 50.
atleast means more than 50.
The number sentence that states that x is at most 50 is option B: x ≤ 50.
In mathematical notation, the symbol "≤" means "less than or equal to." So, x ≤ 50 translates to "x is less than or equal to 50."
This means that x can be any value that is less than 50 or exactly 50.
Option A (x < 50) would mean "x is less than 50," excluding the value 50 itself.
Option C (x = 50) would mean "x is equal to 50," but it doesn't include any values less than 50.
Option D (x > 50) would mean "x is greater than 50," excluding the value 50 itself.
Option E (x ≥ 50) would mean "x is greater than or equal to 50," which includes values greater than 50, but it doesn't allow any values less than 50.
So, the correct choice to state that x is at most 50 (including the value 50) is option B: x ≤ 50.

find the nth maclaurin polynomial for the function. f(x) = sin(x), n = 3
P3(x) = ___
Answers
The third-degree Maclaurin polynomial for f(x) = sin(x) is P3(x) = x - (x^3) / 6.
To find the nth Maclaurin polynomial for the function f(x) = sin(x) when n = 3, we need to compute the polynomial up to the third-degree term.
The Maclaurin polynomial for a function f(x) centered at x = 0 is given by the formula:
Pn(x) = f(0) + f'(0)x + (f''(0)x^2) / 2! + (f'''(0)x^3) / 3! + ...
Let's calculate the nth Maclaurin polynomial for f(x) = sin(x) when n = 3:
First, we find the values of the function and its derivatives at x = 0:
f(0) = sin(0) = 0
f'(x) = cos(x), so f'(0) = cos(0) = 1
f''(x) = -sin(x), so f''(0) = -sin(0) = 0
f'''(x) = -cos(x), so f'''(0) = -cos(0) = -1
Using these values, we can write the Maclaurin polynomial:
P3(x) = 0 + 1x + (0x^2) / 2! + (-1x^3) / 3!
Simplifying further, we have:
P3(x) = x - (x^3) / 6.
Therefore, the third-degree Maclaurin polynomial for f(x) = sin(x) is:
P3(x) = x - (x^3) / 6.

(0.06) · (0.154)When multiplying decimals, multiply as if there are no decimal points:
\(\implies 6 \times 154 = 924\)
Count the number of digits after the decimal in each factor:
0.06 → 2 digits0.154 → 3 digitsTherefore, there is a total of 5 digits.
Put the same number of total digits after the decimal point in the product:
\(\implies (0.06) \cdot (0.154)=0.00924\)
-----------------------------------------------------------------------------------------------
Answer option A
\(\boxed{6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}}\)
When dividing by multiples of 10 (e.g. 10, 100, 1000 etc.), move the decimal point to the left the same number of places as the number of zeros.
Therefore:
6 ÷ 100 = 0.06154 ÷ 1000 = 0.154\(\implies 6 \cdot \dfrac{1}{100} \cdot 154 \cdot \dfrac{1}{1000}=(0.06) \cdot (0.154)\)
Therefore, this is a valid answer option.
Answer option B
\(\boxed{6 \cdot 154 \cdot \dfrac{1}{100000}}\)
Multiply the numbers 6 and 154:
\(\implies 6 \times 154 = 924\)
Divide by 100,000 by moving the decimal point to the left 5 places (since 100,000 has 5 zeros).
\(\implies 6 \cdot 154 \cdot \dfrac{1}{100000}=0.00924\)
Therefore, this is a valid answer option.
Answer option C
\(\boxed{6 \cdot (0.1) \cdot 154 \cdot (0.01)}\)
Again, employ the technique of multiplying decimals by first multiplying the numbers 6 and 154:
\(\implies 6 \cdot 154 = 924\)
Count the number of digits after the decimal in each factor:
0.1 → 1 digit0.01 → 2 digitsTherefore, there is a total of 3 digits.
Put the same number of digits after the decimal point in the product:
\(\implies 0.924\)
Therefore, as (0.06) · (0.154) = 0.00924, this answer option does not equal the given expression.
Answer option D
\(\boxed{6 \cdot 154 \cdot (0.00001)}\)
Again, employing the technique of multiplying decimals.
As there are a total of 5 digits after the decimals:
\(\implies 6 \cdot 154 \cdot (0.00001)=0.00924\)
Therefore, this is a valid answer option.
Answer option E
\(\boxed{0.00924}\)
As we have already calculated, (0.06) · (0.154) = 0.00924.
Therefore, this is a valid answer option.

The NWBC found that 16.5% of women-owned businesses did not provide any employee benefits. What sample size could be 99% confident that the estimated (sample) proportion is within 6 percentage points of the true population proportion?
Answers
A sample size of 329 would be required to be 99% confident that the estimated proportion of women-owned businesses not providing employee benefits is within 6 percentage points of the true population proportion.
To calculate the required sample size, we can use the formula:
n = (\(z^2\) * p * q) /\(e^2\)
where n is the sample size, z is the z-score corresponding to the desired level of confidence (in this case, 2.576 for 99% confidence), p is the estimated population proportion (0.165, based on the NWBC's finding), q is 1-p, and e is the maximum error we want to tolerate (in this case, 0.06 or 6 percentage points).
Substituting the values, we get:
n = (2.576^2 * 0.165 * 0.835) / \(0.06^2\)
Solving for n, we get:
n ≈ 329
Therefore, a sample size of 329 would be required to be 99% confident that the estimated proportion of women-owned businesses not providing employee benefits is within 6 percentage points of the true population proportion. Note that this assumes a simple random sample and that the population size is much larger than the sample size, so the finite population correction is not needed.

Given that ⁵∫₀ (x)x = -9 and ⁵∫₀ (x)x = 26, we need to evaluate the integral ⁵∫₀ ((x)+(x))x. By applying the linearity property of integrals, we can split the integral into two parts: ⁵∫₀ (x)x dx + ⁵∫₀ (x)x dx. Substituting the given values, we have -9 + 26 = 17 as the result of the integral.
To calculate ⁵∫₀ ((x)+(x))x, we can apply the linearity property of integrals, which states that the integral of a sum is equal to the sum of the integrals.
Therefore, we can rewrite the integral as ⁵∫₀ (x)x dx + ⁵∫₀ (x)x dx.
Substituting the given values, we have ⁵∫₀ (x)x dx + ⁵∫₀ (x)x dx = -9 + 26 = 17.
