Answer:

Width __6___ cm

Length __12__ cm

Step-by-step explanation:

hello :

x : the width   and y : Length    P : the  perimeter

P=2(x+y )        but : P=36cm  and : y = 2x

36 = 2(x+2x)

36 = 2(3x)

6x =36   so : x=6 cm   and y = 2×6=12cm

Step-by-step explanation:

If breadth is b,then length will be 2b,so

Perimeter=36

2(2b+b)=36

3b=18

b=6,so,l=2×6=12

So,length is 12 and breadth is 6,

Answer:

see explanation

Step-by-step explanation:

Given

tan a = \(\frac{9}{40}\) = \(\frac{opposite}{adjacent}\)

We require the hypotenuse h

Using Pythagoras' identity

h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )

h = \(\sqrt{1681}\) = 41 , thus

sin a = \(\frac{opposite}{hypotenuse}\) = \(\frac{9}{41}\)

cos a = \(\frac{adjacent}{hypotenuse}\) = \(\frac{40}{41}\)

Finding the centroid of a triangle is an important task in mathematics as it helps in determining the center of mass of the triangle. The centroid is a point where all three medians of the triangle intersect. A median is a line segment that connects a vertex to the midpoint of the opposite side. In this case, we have been given the vertices of a triangle, and we need to find its centroid. The given vertices are D(2,-8), E(2, -2), F(8, -2).

To find the centroid of the triangle, we need to first find the coordinates of the midpoints of each side. We can do this by using the midpoint formula which states that the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2). Using this formula, we find that the midpoints of the sides are (2, -5), (5, -2), and (5, -5).

Next, we need to find the equation of the medians. We can do this by using the point-slope formula which states that the equation of a line passing through a point (x1, y1) with slope m is y-y1=m(x-x1). Using this formula, we find that the equations of the medians passing through the midpoints (2, -5), (5, -2), and (5, -5) are x=3.5, y=-5/3 x - 11/3, and y=-x+10, respectively.

Finally, we find the point of intersection of these three medians to get the centroid of the triangle. Solving the equations, we find that the centroid is at (5, -4). Therefore, the coordinates of the centroid of the triangle with vertices D(2,-8), E(2, -2), F(8, -2) are (5, -4).

The higher bacterial count means dirtier hands after washing.

Given data: A student decides to investigate how effective washing with soap is in eliminating bacteria. To do this, she tested four different methods: washing with water only, washing with regular soap, washing with antibacterial soap, and spraying hands with an antibacterial spray (containing 65% ethanol as an active ingredient). She suspected that the number of bacteria on her hands before washing might vary considerably from day to day. To help even out the effects of those changes, she generated random numbers to determine the order of the four treatments.

Each morning she washed her hands according to the treatment randomly chosen. Then she placed her right hand on a sterile media plate designed to encourage bacterial growth. She incubated each play for 2 days at 360C, after which she counted the number of bacteria colonies. She replicated this procedure 8 times for each of the four treatments. Remember that higher bacteria count means dirtier hands after washing.

While it is not very likely that there will be exactly 14 births on any given day, it is still possible, and the probability of it happening is about 8.3%.

Let's start by calculating the mean or average number of births per day. To do this, we divide the total number of births in a year (4126) by the number of days in a year. Since there are 365 days in a year, the mean number of births per day is:

4126 / 365 = 11.3

This means that on average, there are about 11 to 12 births per day in this hospital.

In this case, the average rate of occurrence is 11.3 births per day. Using the Poisson distribution formula, we can calculate the probability of having 14 births in a day as follows:

P(X=14) = (e⁻¹¹°³) x (11.3¹⁴) / 14!

where e is the mathematical constant approximately equal to 2.71828, X is the random variable representing the number of births in a day, and ! represents the factorial function.

Using a calculator or a software tool, we get:

P(X=14) = 0.083

This means that the probability of having exactly 14 births in a day is about 8.3%.

Answer:

120° will be found on in the second quadrant of the unit circle. Specifically, the reference angle will be 60°. This is because the angle measurement starts from the positive x axis, and rotates 120° counter-clockwise. The angle formed at this point between the line and the x-axis (negative direction) is 60°.

The special right triangle formed will have a hypotenuse of 1, and a reference angle of 60°.

We know that the adjacent line, the line opposite the 30° angle, will be 1/2 the hypotenuse, or -1/2. Negative because it goes in the negative x direction.

The opposite end, or vertical side, will be √3/2.

sin(120) = opposite/hypotenuse = √3/2 ÷ 1 = √3/2

cos (120) = adjacent/hypotenuse = (-1/2) / 1 = -1/2

tan (120) = opposite / adjacent = (√3/2) / (-1/2) = -√3

The Euler equation represents the relationship between current-period consumption and future-period consumption in the optimum. It is derived from intertemporal optimization in economics.

In the context of consumption, the Euler equation can be expressed as:

u'(Ct) = β * u'(Ct+1)

where:

- u'(Ct) represents the marginal utility of consumption in the current period,

- Ct represents current-period consumption,

- β is the discount factor representing the individual's time preference,

- u'(Ct+1) represents the marginal utility of consumption in the future period.

This equation states that the marginal utility of consumption in the current period is equal to the discounted marginal utility of consumption in the future period. It implies that individuals make consumption decisions by considering the trade-off between present and future utility.

Note: The Euler equation assumes a constant discount factor and a utility function that is differentiable and strictly concave.

Area between the curve is -0.023 square units on the interval.

The area between the curve \(f(x) = sin^2(2x) and g(x) = tan^2(x)\) on the interval [0, π/3] as accurately as possible is to be calculated. The graphs of \(f(x) = sin^2(2x)\) and\(g(x) = tan^2(x)\) on the given interval are to be plotted and the area between the graphs is to be calculated as shown below: Interval: [0, π/3]

Graph:\(f(x) = sin^2(2x)g(x) = tan^2(x)\) The area between the two graphs on the given interval is to be calculated.The graph of tan²(x) intersects the x-axis at x = nπ, where n is an integer. Thus,\(tan^2(x)\) intersects the x-axis at x = 0 and x = π.

The intersection point of \(f(x) = sin^2(2x), g(x) = tan^2(x)\)is to be found by equating f(x) and g(x) and solving for x as shown below:sin²(2x) = tan²(x)sin²(2x) - tan²(x) = 0(sin(2x) + tan(x))(sin(2x) - tan(x)) = 0sin(2x) + tan(x) = 0 or sin(2x) - tan(x) = 0tan(x) = - sin(2x) or tan(x) = sin(2x)\(sin(2x)\)

Using the graph of tan(x) and sin(2x), the solution x = 0.384 is obtained for the equation tan(x) = sin(2x) in the given interval.Substituting the values of f(0.384) and g(0.384) into the expression for the area between the graphs using integral calculus:

\(∫[0,π/3] (sin²(2x) - tan²(x)) dx = [∫[0,0.384] (sin²(2x) - tan²(x)) dx] + [∫[0.384,π/3] (sin²(2x) - tan²(x)) dx]\)

Using substitution, u = 2x for the first integral and u = x for the second integral:

\(∫[0,π/3] (sin²(2x) - tan²(x)) dx= [1/2 ∫[0,0.768] (sin²(u) - tan²(u/2)) du] + [-∫[0.384,π/3] (tan²(u/2) - sin²(u/2)) du]\)

Evaluating each integral using integral calculus, the expression for the area between the curves on the interval [0, π/3] as accurately as possible is given by: \([1/2 (-1/2 cos(4x) + x) [0,0.768] - 1/2 (cos(u) + u) [0.384, π/3]] = [0.198 - 0.221]\) = -0.023 square units.

Answer:

$600

Step-by-step explanation:

Let x be the total amount divided

Karen gets (2/7) x

Natasha gets  (5/7) x

(5/7) x  = (2/7) x + 210

Multiply both sides by 7

5x = 2x + 1470

3x = 1470

x = 490

Natasha gets (5/7) (490) = 350

Karen gets (2/7)(490) = 140

The difference in ration is 5 - 3 = 2. So divide 150 by 2 to get the amount for each part of the ratio which is 75. the total ration is 3 + 5 = 8. So to get the total original sum of money, multiply 75 and 8 which is $600. for each person just multiply 75 with their respective ratios. For A: 75 X 3 = $225. For B: 75 x 5= $375. To check that it is correct add 225 and 375, and you should get 600.

according to my calculations, the starting amount will be 600

Answer:

$280

Step-by-step explanation:

Ratio = 2 : 5

Karen's Share = 2x

Natasha's share = 5x

Natasha received $120 more than karen.

5x = 2x + 120

5x - 2x = 120

      3x = 120

        x = 120/3

x = 40

Karen's share = 2*40 = $ 80

Natasha's share = 5*40 = $ 200

Sum of money = 80 +200 = $ 280

To find the percent increase between the average low and high temperatures in July, we need to calculate the difference between the average high and low temperatures and then divide that difference by the average low temperature. Finally, we multiply the result by 100 to get the percentage increase.

The difference between the average high and low temperatures is:

90°F - 69°F = 21°F

To find the percentage increase, we need to divide the difference by the average low temperature and multiply by 100:

Percentage increase = (21°F / 69°F) × 100%

≈ 30.4%

Therefore, the percent of increase between the average low and high temperatures in July is approximately 30.4%, rounded to the tenths place.

The correct statement is c. The Adjusted R-squared is a measure used in multiple regression analysis that is between 0 and 1. It is different from the R-squared value in simple linear regression.

The Adjusted R-squared can decrease if the addition of another X regressor does not sufficiently lower the sum of squared residuals (SSR) relative to the impact of increasing the number of predictors (k). It measures the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size, rather than the ratio of the sum of squared residuals to the total sum of squares. It provides a measure of how well the regression model fits the data, and it ranges between 0 and 1. A value closer to 1 indicates that a higher proportion of the variance in the dependent variable is explained by the predictors.

Adding another X regressor to the multiple regression model can impact the Adjusted R-squared. If the additional regressor does not significantly contribute to reducing the sum of squared residuals (SSR) relative to the increase in the number of predictors (k), the Adjusted R-squared can decrease. This means that the added regressor does not improve the model's ability to explain the variance in the dependent variable adequately.

However, the Adjusted R-squared does not directly measure the ratio of the sum of squared residuals to the total sum of squares. Instead, it represents the proportion of the variance explained by the predictors, adjusted for the number of predictors and the sample size. It penalizes models with a large number of predictors that may overfit the data, thereby providing a more reliable measure of the model's goodness of fit.

The pirate has gone into debt by $38,979 in base 10 due to his encounter with Captain Rusczyk.

To determine the amount of debt, we need to calculate the difference between the value of the goods the pirate stole and the amount demanded by Captain Rusczyk. The pirate initially stole $2345_6, which means it is in base 6. Converting this to base 10, we have $2\times6^3 + 3\times6^2 + 4\times6^1 + 5\times6^0 = 2\times216 + 3\times36 + 4\times6 + 5\times1 = 432 + 108 + 24 + 5 = 569$.

Captain Rusczyk demanded $41324_5, which means it is in base 5. Converting this to base 10, we have $4\times5^4 + 1\times5^3 + 3\times5^2 + 2\times5^1 + 4\times5^0 = 4\times625 + 1\times125 + 3\times25 + 2\times5 + 4\times1 = 2500 + 125 + 75 + 10 + 4 = 2714$.

Therefore, the pirate has gone into debt by $569 - 2714 = -2145$. Since the pirate owes money, we consider it as a negative value, so the pirate has gone into debt by $38,979 in base 10.

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

Two functions,

f(x) = x + 4

g(x) = x – 3

the difference in values of function f(x) & g(x)

f(x) -  g(x) =  x + 4 - ( x – 3 )

                =  x + 4 - x +3

                =    7

So, if we subtract 7 from the function f(x)

⇒    x + 4 - 7

⇒    x  - 3

So, vertical translation required is  value 7 and in downward direction
