Answer:

Refer the attached figure below.                  

Step-by-step explanation:

Given : The rose curve  r=-3\sin (5\theta)

To find : Draw a graph of the rose curve?

Solution :

We have given the curve  r=-3\sin (5\theta) in polar form.

In Cartesian coordinates, a point is specified by X and Y values.

In polar coordinates, a point is specified by r and θ

Where, r is the point radical distance from the origin.

and θ is the angle that gives the direction between the positive x axis and the point.

Now, we plot the graph of curve r=-3\sin (5\theta)

where, 0\leq \theta \leq 2\pi

Refer the attached figure below.

9 ^ (- 1/2) + 25 ^ (- 1/2) + 32 ^ (3/5)<br> Evaluate
WINSTONCH [101]

Answer:

8.533333

Step-by-step explanation:

9^(− 1/ 2 )+25− 1 2 +32^ (3/ 5) = 9 (−1 /2) +25(− 1 /2) +32 ^(3 /5)

=0.333333+25^(− 1/ 2) +32 ^(3 /5)

=0.333333+25 ^(−1 /2) +32 ^(3/ 5)

=0.333333+0.2+32^ (3/ 5)

=0.533333+32 ^(3 /5)

=0.533333+8

=8.533333

The water works commission needs to know the mean household usage of water by the residents of a small town in gallons per day.
valina [46]

Answer:

A sample of 179 is needed.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.85}{2} = 0.075

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.075 = 0.925, so Z = 1.44.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

A previous study found that for an average family the variance is 1.69 gallon?

This means that \sigma = \sqrt{1.69} = 1.3

If they are using a 85% level of confidence, how large of a sample is required to estimate the mean usage of water?

A sample of n is needed, and n is found for M = 0.14. So

M = z\frac{\sigma}{\sqrt{n}}

0.14 = 1.44\frac{1.3}{\sqrt{n}}

0.14\sqrt{n} = 1.44*1.3

\sqrt{n} = \frac{1.44*1.3}{0.14}

(\sqrt{n})^2 = (\frac{1.44*1.3}{0.14})^2

n = 178.8

Rounding up

A sample of 179 is needed.

A construction worker fills a mold with concrete. This solid figure represents the mold.
nadezda [96]

Answer:

volume = 338 x 20 = 6760 cm^3

Step-by-step explanation:

large rectangular top area = 14 x 22 = 308 cm^2

small rectangular top area = 6x5 = 30 cm^2

total top area = 308 + 30 = 338 cm^2

volume = 338 x 20 = 6760 cm^3
