The diameter of a circle is 38 centimeters. What is the circle's circumference?
Use 3.14 for л.

The polynomial can be written as:

f(x) = x³ - 3x² + 4x - 2

We know that the degree is 3, and two of the roots are x = 1 and x = 1 + i.

Then the last root must be 1 - i, so the polynomial is real, then if the leading coeficient of the polynomial is a, we can write:

f(x) = a*(x - 1)*(x - (1+ i))*(x - (1 - i))

Expanding that:

f(x) = a*(x - 1)*[x² -2x + 2]

f(x) = a*(x³ - 2x² + 2x - x² + 2x - 2)

f(x) = a*(x³ - 3x² + 4x - 2)

And we know that f(0) = -2, then we need to solve:

-2 = a*(0³ - 3*0² + 4*0 - 2)

-2 = a*-2

So a = 1

The polynomial is:

f(x) = x³ - 3x² + 4x - 2

Clara should use the 50% off coupon to save the most money on a tent originally priced at $46.


To determine which coupon will save Clara the most money, we need to calculate the final price of the tent with each coupon.

For the $24 off coupon:
Final price = Original price - Coupon amount
Final price = $46 - $24
Final price = $22

For the 50% off coupon:
Final price = Original price - (Original price x Coupon percentage)
Final price = $46 - ($46 x 0.50)
Final price = $46 - $23
Final price = $23

As we can see, the final price of the tent with the $24 off coupon is $22, while the final price with the 50% off coupon is $23. Therefore, Clara should use the $24 off coupon to save the most money.

Based on the figure, the measure of the angle GPY is 118 degrees.

Alternate angles are a pair of angles that are formed by a transversal intersecting two parallel lines.

When a transversal intersects a parallel line, it creates four angles.

Alternate angles are the pairs of angles that are on opposite sides of the transversal and on opposite sides of the parallel lines.

The key property of alternate angles is that they are congruent, meaning they have the same measure.

Here angle GPY is alternate to angle RPK.

Thus;

8p + 94 = 5p + 103

8p - 5p = 103 - 94

3p = 9

Divide both sides by 3;

p = 3

The measure of angle GPY becomes ;

The limiting probabilities are π0 = 7/12 and π1 = 5/12.

Verify that this is an irreducible ergodic Markov chain.

An irreducible Markov chain is one in which it is possible to move from any state to any other state in a finite number of steps. In this case, the probability transition matrix P is:

P = [0.4 0.6]

   [0.7 0.3]

Since there are non-zero probabilities in every row and column, it is possible to move from any state to any other state in a finite number of steps. Therefore, this is an irreducible Markov chain.

An ergodic Markov chain is one in which every state is positive recurrent and aperiodic. Since this is an irreducible Markov chain, every state is positive recurrent. Additionally, there are no cycles in the transition matrix, so every state is aperiodic. Therefore, this is an ergodic Markov chain.

Compute the two step transition probability matrix P(2).

The two step transition probability matrix P(2) is obtained by multiplying the matrix P by itself:

P(2) = P * P = [0.4 0.6] * [0.4 0.6]

                  [0.7 0.3]                    [0.7 0.3]

         = [0.4*0.4 + 0.6*0.7  0.4*0.6 + 0.6*0.3]

              [0.7*0.4 + 0.3*0.7  0.7*0.6 + 0.3*0.3]

         = [0.58  0.42]

              [0.49  0.51]

Find the limiting probability π0 and π1.

The limiting probabilities are the stationary probabilities of the Markov chain, which are obtained by solving the following system of equations:

π0 = 0.4*π0 + 0.7*π1

π1 = 0.6*π0 + 0.3*π1

π0 + π1 = 1

Solving this system of equations gives:

π0 = 7/12

π1 = 5/12

Therefore, the limiting probabilities are π0 = 7/12 and π1 = 5/12.

The ANOVA will depend on the total sample size.

a. False. The psychologist's reasoning is incorrect, as the critical value for evaluating the ratio of between-group mean squares to within-group mean squares for the ANOVA does not depend solely on the total sample size, but also on the number of groups being compared and the level of significance. Furthermore, a Bonferroni adjusted post-hoc test does not require the p-value for each pairwise comparison to be no more than .0083 to be considered as statistically significant.

b. True. The critical value for evaluating the ratio of between-group mean squares to within-group mean squares for the ANOVA will depend on the total sample size, as well as on the number of groups being compared and the level of significance.

If 41 grams of sugar is 14% of the normal daily allowance for sugar, we can set up a proportion to solve for the recommended amount:

41 grams / x = 14% / 100%

where x is the recommended amount of sugar.

To solve for x, we can cross-multiply and simplify:

41 / 0.14 = x / 1

x = 292.86

Rounding to the nearest gram, the recommended amount of sugar in a normal diet is approximately 293 grams.

The equation of the line with slope 4 that goes through the point (-3,0) is y = 4x + 12.

The equation of the line passing through the point (-3,0) with a slope of 4 can be found using the point-slope form of a line's equation:

y - y1 = m(x - x1)

where the provided point is (x1, y1), and m is the slope.

When we change the values, we obtain:

y - 0 = 4(x - (-3))

Making the right side simpler:

y = 4x + 12

The reflection of the shape over the line p is drawn and added as an attachment

When a shape is reflected over a line, it is flipped across that line. The reflected image of the shape is a mirror image of the original shape, and appears to be a mirror image of the original shape.

This means that we simply flip the shape over the line of reflection

The line over which the shape is reflected is called the line of reflection, and it acts as a mirror. In this case, it is the line p. The shape and its reflected image are symmetric with respect to the line of reflection.

Flipping the shape would result in any point on the original shape and its corresponding point on the reflected image are equidistant from the line of reflection, as the distance between a point and its reflected image is equal to twice the perpendicular distance from the point to the line of reflection.

The torque required to maintain motion of the rotating conical body in the oil film is 0.149 N·m.

The torque required to maintain motion of a rotating conical body in an oil film can be found using the equation T = (2πμωR^3h)/ln(R/h), where T is the torque, μ is the viscosity of the oil, ω is the angular velocity of the cone, R is the radius of the base of the cone, and h is the thickness of the oil film.

First, we need to convert the given values into the appropriate units. The diameter of the base of the cone is 18cm, so the radius is 9cm or 0.09m. The thickness of the oil film is 0.8mm, or 0.0008m. The viscosity of the oil is 4·10^-3 N·S/m^2, and the angular velocity of the cone is 37 rad/s.

Now we can plug these values into the equation:

T = (2π)(4·10^-3 N·S/m^2)(37 rad/s)(0.09m)^3/(0.0008m)

T = 0.149 N·m

Therefore, the torque required to maintain motion of the rotating conical body in the oil film is 0.149 N·m.

To select the indicated motor, we need to find a motor that can provide a torque of at least 0.149 N·m. This will ensure that the motor can maintain the constant motion of the conical body in the oil film.
