What ray is between OC and OA?

Answer:

A: 6X6 + 8x5 + 2x4

Step-by-step explanation:

The unit price per folder in one box of "1/5 cut color hanging folders" at the regular price is $0.2996 per folder. The unit price on the special offer, "buy 2 get 1 free," is $0.1997 per folder.

To calculate the unit price per folder, we divide the total price by the number of folders in a box. The regular price is $7.49 per box, and there are 25 folders in a box. Therefore, the unit price per folder in one box at the regular price is $7.49 / 25 = $0.2996 per folder.

On the special offer, "buy 2 get 1 free," we need to consider the total price for two boxes since we get one box free. The total price for two boxes is $7.49 * 2 = $14.98. Considering that we get three boxes (75 folders) in total, the unit price per folder on the special offer is $14.98 / 75 = $0.1997 per folder.

Comparing the unit prices, the special offer provides a better buy with a lower unit price per folder ($0.1997) compared to the regular price per folder ($0.2996).

It will take the town 21 years 4 months to reach 4600 in population

a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

initial population = 3000

population increase every year = 2.5% of 3000

which is 2.5/100 x 3000 = 75

let the time taken to reach 4600 be d

increment for d number of years = 75d

Total population after d years is 75d + 3000

so 75d + 3000 = 4600

75d = 4600  - 3000

75d = 1600

d = 1600/75

d = 21.33 years which is 21 years 4 months

In conclusion 21 years 4 months is the time taken for the ton tto get tto 4600

The value of the missing angles of the quadrilateral are:

a = 110°

b = 70°

c = 20°

Theorem sum of angles in a triangle states that they sum up to 180 degrees. Thus:

d = 180 - (78 + 32)

d = 70°

Similarly:

e = 180 - (78 + 32 + 18)

e = 20°

Sum of angles on a straight line is 180 degrees. Thus:

a = 180 - 70

a = 110°

We can see that e + b will be equal to 90 degrees because of the definition of right angles. Thus:

b = 90° - 20°

b = 70°

From sum of angles in a triangle as 180° is:

c = 180 - (90 + 70)

The dimensions of the scale model of your room would be 3/4 inch represents 1 foot. To determine the dimensions of the scale model, we need to apply the scale ratio of 3/4 inch represents 1 foot.

Let's assume the length and width of your actual room are L feet and W feet, respectively. To find the dimensions of the scale model, we can multiply the actual dimensions by the scale ratio.

The length of the scale model would be L * (3/4) inch, and the width would be W * (3/4) inch.

For example, if your actual room is 12 feet long and 10 feet wide, the dimensions of the scale model would be:

Length of the scale model = 12 feet * (3/4) inch = 9 inches

Width of the scale model = 10 feet * (3/4) inch = 7.5 inches

Therefore, the scale model would have a length of 9 inches and a width of 7.5 inches, based on the given scale ratio.

It's important to note that when creating a scale model, maintaining the proportionality between the actual dimensions and the model dimensions is crucial to accurately represent the physical space in a smaller scale.

Answer:

the answer is nonagon

A nonagon is a polygon made up of 9 sides and 9 angles.

Answer:

The slope is 2/3 and for the unit rate I think it has to do with how the sales go up $1,000 every three days.

Answer:

The measures of those two angles are 45 and 85 degrees.

Step-by-step explanation:

The three interior angles of a triangle add up to 180 degrees.

So if one angle is 50 degrees then

180 - 50 = 130

The other two angles must add up to 130

If the ratio is 9:17 that means there must be 26 equal parts

9 + 17 = 26

130/26 = 5

Every part equals 5 so

9 x 5 = 45

17 x 5 = 85

The measure of the two angles are 45 and 85 degrees.

Step-by-step explanation:

We can use the formula for exponential growth to find the rate at which the sunfish gains mass:

M(t) = M(0) * e^(kt)

where:

M(0) = the initial mass of the sunfish (which we don't know)

k = the growth rate constant (which we also don't know yet)

t = the elapsed time since the sunfish was born (in days)

e = the mathematical constant approximately equal to 2.71828...

We are given the formula for M(t), which is:

M(t) = 4 * (81/49)^t

This means that M(0) = 4 * (81/49)^0 = 4.

To find the growth rate constant k, we can use the fact that the sunfish gains 2/7 of its mass every day. This means that the daily growth rate is 2/7 of the current mass. In other words, the daily growth rate is:

(2/7) * M(t)

We can relate this to the exponential growth formula by taking the derivative of M(t) with respect to t:

dM/dt = k * M(t)

Taking the derivative of M(t), we get:

dM/dt = ln(81/49) * 4 * (81/49)^t

Setting this equal to the daily growth rate, we get:

(2/7) * M(t) = ln(81/49) * 4 * (81/49)^t

Simplifying this expression, we get:

k = ln(81/49) * 4/7

Using a calculator, we can evaluate this expression to get:

k ≈ 0.0919

Therefore, the rate at which the sunfish gains mass is given by:

dM/dt = 0.0919 * M(t)

To find out how much mass the sunfish gains in one day, we can substitute M(t) = 4 * (81/49)^t into this formula and evaluate it at t = 1 (since we want to know the daily rate of change):

dM/dt = 0.0919 * 4 * (81/49)^1

dM/dt ≈ 0.54

This means that the sunfish gains 0.54 milligrams every day. To express this as a fraction of its mass, we can divide by the current mass:

(0.54/4) ≈ 0.1375

So the sunfish gains approximately 2/7 (or 0.2857) of its mass every 2.08 (or 7/2.54) days. Rounded to two decimal places, this is 0.14 or approximately 2/7 of its mass every 2.08 days.

Answer:

(-7x + 4)(-7x - 4)

Step-by-step explanation:

When you multiply two binomials together and you want the result to be the difference of squares, the two binomials must have the same terms and ONE of the terms must have the opposite sign.

Ex: (a+b)(a-b)

OR (x+2)(x-2)

OR (m-3)(m+3)

OR (2x+1)(2x-1)

OR (-5n+7)(-5n-7)

These multiplications

(–7x + 4)(–7x + 4) and

(-7x + 4)(4 - 7x) yield a perfect square trinomial.. Both factors are identical, so they are not the answer.

(–7x + 4)(7x – 4) is also not the answer because one factor is the opposite of the other factor. That is, both terms in one factor are the opposite sign from the other. We need just ONE term to have the opposite sign.

Difference of squares:

(a+b)(a-b)=

a^2 - b^2

The equation of the tangent line to the curve y = 2x cos(n) at the point (π, -π) is y = -2x + (2π + 2nπ sin(n) - π), where m = -2 - 2nπ sin(n) and b = 2π + 2nπ sin(n) - π.

To find the equation of the tangent line, we need to find the derivative of y with respect to x, and then evaluate it at the given point (π, -π) to find the slope of the tangent line. Then we can use the point-slope form of a line to find the equation of the tangent line in the form y = mx + b.

Taking the derivative of y with respect to x, we get:

dy/dx = 2cos(n) - 2n x sin(n)

Evaluating this derivative at x = π, we get:

dy/dx |x=π = 2cos(n) - 2n π sin(n)

Substituting x = π and y = -π into the original equation, we get:

-π = 2πcos(n)

cos(n) = -1/2

Since we want the equation of the tangent line at the point (π, -π), we can substitute x = π and y = -π into the point-slope form of a line:

y - (-π) = m(x - π)

Simplifying, we get:

y = m(x - π) - π

Substituting cos(n) = -1/2, we have:

dy/dx |x=π = 2cos(n) - 2n π sin(n) = -2 - 2nπ sin(n)

Setting this equal to the slope of the tangent line, we have:

m = -2 - 2nπ sin(n)

Substituting this value of m into the equation of the tangent line, we have:

y = (-2 - 2nπ sin(n))(x - π) - π

Therefore, the equation of the tangent line is:

y = -2x + (2π + 2nπ sin(n) - π)

To test for an association between a categorical variable and a numerical variable, you can use a statistical method called Analysis of Variance (ANOVA).

In this case, you would use a one-way ANOVA to compare the mean salaries of professors across the four different ranks. This would allow you to determine if there is a significant difference in salary between the different ranks. It is important to note that ANOVA assumes that the numerical variable is normally distributed and that the variances are equal across the different groups. Additionally, post-hoc tests may be necessary to determine which specific groups have significantly different mean salaries. Keep in mind that the sample size and distribution of data can affect the validity of your results. A larger sample size and more normally distributed data will generally result in more accurate conclusions. To test the association between a categorical variable (professor rank with four levels) and a numerical variable (yearly salary), you can use the Analysis of Variance (ANOVA) test. ANOVA helps determine if there are significant differences among the means of different groups (ranks) and if these differences are not due to random chance. If the ANOVA test results show a significant association, it implies that the professor's rank is related to their yearly salary.

Step-by-step explanation:

They are congruent so there side leghths are the same.

Step 1: The proposed probe for flaw detection in type 316L austenitic stainless steel plates is an eddy current probe with a suitable height, diameter, and frequency.

Step 2: Eddy current testing is an effective non-destructive testing method for detecting flaws in conductive materials. In this case, the eddy current probe should have a suitable height, diameter, and frequency to ensure accurate flaw detection.

The height of the probe should be adjusted to maintain a constant lift-off of 0.2 mm, which is the distance between the probe and the surface of the material being tested. This ensures consistent measurement conditions and reduces the influence of lift-off variations on the test results.

The diameter of the probe should be selected based on the size of the flaws and the desired spatial resolution. It should be small enough to accurately detect the flaws but large enough to cover the entire flaw area during scanning.

The frequency of the eddy current probe determines the depth of penetration into the material. Higher frequencies provide shallower penetration but higher resolution, while lower frequencies provide deeper penetration but lower resolution. The frequency should be chosen based on the expected depth of the flaws and the desired level of sensitivity.

Overall, the eddy current probe with suitable height, diameter, and frequency can effectively detect the artificial flaws in type 316L austenitic stainless steel plates fabricated using a powderbed-based laser metal additive manufacturing machine.
