A belt runs a pulley at 80 revolutions per minute.

(a) To find the angular speed of the pulley in radians per second, we can use the formula

ω = 2πf

Where

ω = angular speed in radians per second

f = frequency in Hertz

We know that the pulley rotates at a rate of 80 revolutions per minute. To convert this to a frequency in Hertz, we can divide by 60 seconds per minute

f = 80 rev/min ÷ 60 min/s = 4/3 Hz

Now we can plug in this value for f into the formula

ω = 2πf = 2π(4/3) = 8π/3 rad/sec

Therefore, the angular speed of the pulley is 8π/3 radians per second.

(b) To find the linear speed of the belt in centimeters per second, we can use the formula

v = rω

Where

v = linear speed in centimeters per second

r = radius of the pulley in centimeters

ω = angular speed in radians per second

We know the radius of the pulley is given in centimeters. Let's assume it is r cm. We just found the angular speed to be 8π/3 radians per second. Now we can plug in these values into the formula

v = rω = r(8π/3) = (8π/3)r cm/s

Therefore, the linear speed of the belt is (8π/3)r centimeters per second.

The area of the curve in the normal distribution is 1.3788.

A probability bell curve should be referred to as the normal distribution. The mean and standard deviation of a normal distribution are 0 and 1, respectively. The kurtosis is 3, and there is no skew. Not all symmetrical distributions are normal, but all normal distributions are symmetrical. A lot of naturally occurring phenomena resemble the normal distribution The majority of price distributions in finance, however, are not exactly normal.

The area for the curve of the normal distribution can be calculated using the area of z-score table.

For the left region we have:

z-score (-0.29) = 0.3859

For the right region we have:

z-score (2.45) = 0.9929

The total area is:

Area = 0.3859 + 0.9929

Area = 1.3788

Hence, the area of the curve in the normal distribution is 1.3788.

Answer:sometimes

Step-by-step explanation:

The equation of a parabola that opens up and has a vertex at (7,7) can be written in the form

The focal diameter of the parabola is 16, which means that the distance from the vertex to the focus is 8 (since the focal diameter is the sum of the distances from the vertex to the focus and from the vertex to the directrix).

To find the equation of the parabola, we need to determine the value of a that will give us the correct focal diameter. The distance from the vertex to the focus is given by the equation sqrt(4a(y - 7)), so we can set this equal to 8 and solve for a:

sqrt(4a(y - 7)) = 8

4a(y - 7) = 64

a(y - 7) = 16

a = 16 / (y - 7)

Substituting this value of a back into the equation for the parabola gives us:

y = (16 / (y - 7))(x - 7)^2 + 7

This is the equation of the parabola that opens up, has a vertex at (7,7), and a focal diameter of 16.

Answer:

r is the radius of the base and s is the slant height of the cone. From the options given, We can make s the subject of the formula. Hence: Option a) s equals StartFraction L A Over pi r EndFraction

Two equivalent equations are s = LA/πr and r = LA/πs

A cone is a shape formed using a series of line segments or lines that connect a common point, called a apex or vertex, to all points on the base of a circle that do not contain a vertex. The distance from the apex of the cone to the base is the height of the cone. A circular base has a measured radius value. And the length from the apex of the cone to any point around the base is the height of the slope. Equations for the surface area and volume of a cone can be derived from these quantities

Volume(V) = ⅓ πr²h cubic units

The total surface area of the cone = πrs + πr²

where, r is radius of the base, s is slant height and h is height of the cone

Given,

Lateral area of cone is denoted by LA

Lateral area of cone = πrs

where r is radius and s is slant height

⇒ LA = πrs

⇒ s = LA/πr

⇒ r = LA/πs

Recall that in this method, we add two terms with the same variable, but with opposite coefficients, so that the sum is zero. In our case, both equations are already set equal to a constant. Notice that the coefficient of y in the second equation, –1, is the opposite of the coefficient of y in the first equation, 1. We can add the two equations to eliminate y without needing to multiply by a constant.

Now that we have eliminated y, we can solve the resulting equation for x

Then, we substitute this value for x into one of the original equations and solve for y.

Answer:

At least 8.96 hours of sleep to be in the top 1%.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\(\mu = 7.45, \sigma = 0.65\)

How many hours of sleep to be on the top 1%?

The top 1% is the 100 - 1 = 99th percentile, which is X when Z has a pvalue of 0.99. So X when Z = 2.327. Then

\(Z = \frac{X - \mu}{\sigma}\)

\(2.327 = \frac{X - 7.45}{0.65}\)

\(X - 7.45 = 0.65*2.327\)

\(X = 8.96\)

At least 8.96 hours of sleep to be in the top 1%.

Thus, the mass is increasing at a rate of 0.15625 kg per hour, and the mass on this day is 4.5 kg.

Let's consider a general formula for finding the rate of increase:Rate of increase = k x original valueHere, k is a constant that represents the rate of increase per unit of time, and the original value is the initial value of the quantity being measured.

For example, if the original value is 3.2 kg and the rate of increase is 0.5 kg per hour, we can use the formula to calculate the mass at any time t as follows: Mass at

time t = 3.2 + (0.5 x t)

where t is the time elapsed in hours.In order to find k, we need to know the rate of increase and the original value.

Once we have these values, we can rearrange the formula to solve for

k:k = rate of increase / original value

For example, if the mass is increasing at a rate of 0.5 kg per hour and the original value is 3.2 kg, we can calculate k as follows:

k = 0.5 / 3.2k = 0.15625

To find the rate of increase on a specific day, we need to know how much time has elapsed since the original value was measured. Once we have this information, we can plug it into the formula we derived earlier:Mass at time t = 3.2 + (k x t)For example, if 8 hours have elapsed since the original value was measured, we can calculate the mass on that day as follows:

Mass at time t = 3.2 + (0.15625 x 8)

Mass at time t = 4.5 kg

Answer:

x = 6 and y = 10

Step-by-step explanation:

If triangle ZMK is congruent to triangle APY, then;

<Z = <A

<M = <P

<K = <Y

Given the following angles

<M = 112

<Y = 41

<K = 13x - 37

<A = 2y + 7

Required

Value of x and y

Since <K = <Y, then;

13x - 37 = 41

Add 37 to both sides

13x - 37 + 37 = 41 + 37

13x = 78

x = 78/13

x = 6

Also <Z + <M + <K = 180

<Z + 112+41 = 180

<Z + 153 = 180

<Z = 180-153

<Z = 27 degrees

Since <Z = <A

27 = 2y + 7

2y = 27-7

2y = 20

y = 20/2

y = 10

Hence x = 6 and y = 10

The dimensions of the smaller rectangle are 13 centimeters by 52 centimeters.

Let's assume the dimensions of the smaller rectangle are length L and width W (in centimeters).

We know that the area of the smaller rectangle is 676 square centimeters:

L * W = 676    ----(1)

We also know that the larger rectangle has a shorter side of 41 centimeters. Let's say the corresponding longer side of the larger rectangle is H centimeters.

The area of the larger rectangle is 3457 square centimeters:

41 * H = 3457    ----(2)

Our current set of equations contains two unknowns. In order to get the smaller rectangle's dimensions, we can simultaneously solve these equations.

In order to find H, we can use equation (2):

H = 3457 / 41

H ≈ 84.22

Now we can substitute this value of H into equation (1):

L * W = 676

We need to find the dimensions (L and W) that multiply to give 676. We can start by looking for factors of 676.

Factors of 676: 1, 2, 4, 13, 26, 52, 169, 338, 676

By trial and error, we can see that the factors that give a close match to the dimensions of the larger rectangle (41 and 84.22) are 13 and 52:

L = 13

W = 52

Therefore, the smaller rectangle has measurements of 13 by 52 centimetres.
