What is the volume of the cylinder below? Radius of 8 height of 3

Answers

Answer 1

Volume = pi times r^2 times height.
So 3.14x8^2x3
8^2 (8 squared=64)
So the answer is 3.14x64x3 which equals 602.88

Answer 2

ANSWER

The volume of the cylinder is

[tex]V= 602.88 \: square \: units[/tex]

EXPLANATION

The formula for calculating the volume of a cylinder is,

[tex]V = \pi \: {r}^{2} h[/tex]

Where

[tex]r = 8[/tex]
is the radius of the cylinder and

[tex]h = 3[/tex]

is the height of the cylinder.

Also we use the approximate value for π which is
[tex]3.14[/tex]

We substitute the above values into the formula to get

[tex]V = 3.14\times {8}^{2} \times 3[/tex]

[tex]V =3.14\times 64 \times 3[/tex]

[tex]V = 602.88 \: square \: units[/tex]

Hence the volume of the cylinder is 602.88 square units.

Solve by using the quadratic formula. 9x2 + 24x + 32 = 0

Answers

The quadratic formula is:

[tex]x= \frac{-b+- \sqrt{ b^{2} -4ac} }{2a} [/tex]

b =coefficient of x term = 24
a = coefficient of squared term = 9
c = constant term = 32

Using the values, we get:

[tex]x= \frac{-24+- \sqrt{576-4(9)(32)} }{2(9)} \\ \\ x= \frac{-24+- \sqrt{-576} }{18} \\ \\ x= \frac{-24+-24i}{18} \\ \\ x= \frac{-4+-4i}{3} \\ \\ x= \frac{-4+4i}{3}, x \frac{-4-4i}{2} [/tex]

The first step for solving this equation is to multiply the first two numbers together.
18 + 24x + 32 = 0
Add together 18 and 32.
50 + 24x = 0
Now move the constant to the right side of the equation and change its sign.
24x = -50
Lastly,, divide both sides of the equation by 24.
x = [tex]- \frac{25}{12} [/tex]
This means that the correct answer to your question is going to be x = [tex]- \frac{25}{12} [/tex] or x = [tex]-2 \frac{1}{12} [/tex] simplified.

Find the absolute maximum of f(x,y) = e^(-x^2-y^2)(x^2+2y^2) on x^2 + y^2 < 2

Answers

[tex]f(x,y)=e^{-x^2-y^2}(x^2+y^2)[/tex]

Notice that converting to polar coordinates, setting
[tex]x=r\cos\theta[/tex]
[tex]y=r\sin\theta[/tex]
[tex]\implies r^2=x^2+y^2[/tex]

allows us to consider [tex]f(x,y)[/tex] as a function of one variable; let's call it [tex]F(r)[/tex], where

[tex]f(x,y)\equiv F(r)=re^{-r}[/tex]

Then

[tex]F'(r)=e^{-r}(1-r)=0\implies r=1[/tex]

We have [tex]F'(r)>0[/tex] for [tex]r<1[/tex], and [tex]F'(r)<0[/tex] for [tex]r>1[/tex], which means [tex]F[/tex] is increasing, then decreasing as [tex]r[/tex] exceeds 1. This suggests that extrema occur for [tex]f(x,y)[/tex] wherever [tex]r^2=x^2+y^2=1[/tex], i.e. along the intersection of the cylinder [tex]x^2+y^2=1[/tex] and [tex]f(x,y)[/tex].

Computing the second derivative of [tex]F(r)[/tex] and setting equal to 0 gives

[tex]F''(r)=-e^{-r}(2-r)=0\implies r=2[/tex]

as a possible point of inflection. We have [tex]F''(r)<0[/tex] for [tex]r<2[/tex], and namely when [tex]r=1[/tex], which means [tex]F(r)[/tex] is concave downward around this point. This confirms that [tex]r=1[/tex] is a site of a maximum. Along this path, we have a maximum value of [tex]F(1)=e^{-1}\approx0.368[/tex].

Next, to check for possible extrema along the border, we can parameterize [tex]f(x,y)[/tex] by [tex]x=\sqrt2\cos t[/tex] and [tex]y=\sqrt2\sin t[/tex], so that

[tex]x^2+y^2=(\sqrt2\cos t)^2+(\sqrt2\sin t)^2=2[/tex]

and we can think of [tex]f(x,y)[/tex] as a function a single variable, [tex]F(t)[/tex], where

[tex]F(t)=2e^{-2}\approx0.271[/tex]

In other words, [tex]f(x,y)[/tex] is constant along its boundary [tex]x^2+y^2=2[/tex], and this is smaller than the maximum we found before.

So to recap, the maximum value of [tex]f(x,y)[/tex] is [tex]\dfrac1e\approx0.368[/tex], which is attained along the surface above the circle [tex]x^2+y^2=1[/tex] in the [tex]x-y[/tex] plane.

What is the sum of the first 35 terms in the series 7 + 9 + 11 + ...?

a.

29

c.

1645

b.

1399

d.

1435

Answers

The answer is d
Hope this helps :)

First find the 35th number in the series using the formula:
an = a1 + (n - 1)d
a1 = first number in the series
d = difference between successive number
n = number of terms
a35 = 7 + (35 - 1)2
a35 = 7 + (34)2
a35 = 7 + 68 = 75.
Therefore, the 35th term is 75.
To find the sum of the first 35 numbers, use the formula:
Sn = n(a1 + an) / 2
Sn = 35(7 + 75) / 2
Sn = 2870 / 2 = 1,435.
Therefore, the sum of the first 35th term is 1,435.
The correct answer is D.

50 POINTS...Which equation would best help solve the following problem? Tania releases a javelin 1.6 meters above the ground with an initial vertical velocity of 25 meters per second. How long will it take the javelin to hit the ground?

Answers

Let [tex]x(t)[/tex] be the vertical position of the javelin at time [tex]t[/tex]. Once it's thrown in the air, the only force acting on it is gravity, so the javelin would be subjected to a constant downward acceleration of approx. 9.8 meters per second per second. So

[tex]x''(t)=-9.8[/tex]

Integrating once with respect to [tex]t[/tex], we get

[tex]x'(t)=-9.8t+C_1[/tex]

where [tex]x'(t)[/tex] is the velocity of the javelin. We're told that [tex]x'(0)=25[/tex], so

[tex]25=-9.8\cdot0+C_1\implies C_1=25[/tex]

Integrating again with respect to [tex]x[/tex] to get

[tex]x(t)=-4.9t^2+25t+C_2[/tex]

and we know the javelin was initially thrown 1.6 meters above the ground, or [tex]x(0)=1.6[/tex], so we get

[tex]1.6=-4.9\cdot0^2+25\cdot0+C_2\implies C_2=1.6[/tex]

So the javelin's position at any time [tex]t[/tex] is given by

[tex]x(t)=-4.9t^2+25t+1.6[/tex]

It will hit ground when [tex]x(t)=0[/tex]. Solve this however you want; you'll find that this will happen at about [tex]t=5.165[/tex] seconds after the javelin has been thrown.

Lana is trying to find an equation for a line that passes through (5, 2) and is parallel to 3x + 2y = 15. explain the steps that lana could take to determine the equation.

Answers

We have the following equation:
3x + 2y = 15

Step 1:
Rewrite given equation:
2y = 15 - 3x
y = 15/2 - (3/2) x

Step 2:
Parallel lines have the same slope:
y = mx + b
m = -3 / 2
y = (- 3/2) x + b

Step 3:
Find b, for this we evaluate the point (5, 2) in the equation:
2 = (- 3/2) (5) + b
2 = (- 15/2) + b
2 + 15/2 = b
19/2

Step 4:
The parallel line is:
y = (- 3/2) x + 19/2

Find the horizontal or oblique asymptote of f(x) = negative 3 x squared plus 7 x plus 1, all over x minus 2

Answers

Find the horizontal or oblique asymptote of f(x) = negative 3 x squared plus 7 x plus 1, all over x minus 2

Finding the horizontal and oblique asymptote of
f(x)= (-3x^2+7x+1)/(x-2)

Solution:

For Horizontal Asymptote:
Line y=L is a horizontal asymptote of the function y=f(x), if either limx→∞f(x)=Llimx→∞f(x)=L or limx→−∞f(x)=Llimx→−∞f(x)=L, and LL is finite.

Calulate limits:

limx→∞(1x−2(−3x2+7x+1))=−∞

limx→−∞(1x−2(−3x2+7x+1))=∞

Thus, there are no horizontal asymptotes.

For Oblique Asymptote:

Do polynomial long division (−3x2+7x+1)/(x-2)=−3x+1+3/(x−2)

The rational term approaches 0 as the variable approaches infinity.

Thus, the slant asymptote is y=−3x+1y=−3x+1.

Two transformations are applied to F(x) to obtain G(x)

1) F(x) is multiplied by 2.
Multiplying a function by a magnitude greater than 1 results vertical stretch.
So, F(x) is stretched by a factor of 2.

2) 5 is subtracted from the function value.
Subtraction of a number indicates downward shift.

So, G(x) is obtained from F(x) by stretching it vertically by a factor of 2 and shifting down by 5 units

Hugo is a veterinarian. He knows the following information about his 41 patrons: 20 patrons in total do not have a dog. 17 patrons in total have a cat. 7 patrons have neither a dog nor a cat. Can you help Hugo organize the results into a two-way frequency table?

Answers

Answer:

4,17,13,7

Step-by-step explanation:

i got it right :)

Final answer:

To assist Hugo in organizing patron pet ownership into a two-way frequency table, calculations were made to determine the number of patrons with both a dog and a cat, leading to a complete frequency table illustrating pet ownership among 41 patrons.

Explanation:

Hugo, the veterinarian, is attempting to organize patron pet ownership information into a two-way frequency table. First, let's establish the total number of patrons which is 41. Since 20 patrons do not have a dog, it implies that 41 - 20 = 21 patrons have a dog. Of the 41 patrons, we know that 17 have a cat. Also, 7 patrons have neither a dog nor a cat. To create the two-way frequency table, we need to figure out how many patrons have both a dog and a cat.

To find the number of patrons with both pets, we add the number of patrons without pets to those with dogs and then subtract from the total number of patrons, which gives us 41 - 20 + 7 = 28. However, since this number includes all dog owners, we need to subtract those who only have dogs and no cats, which gives us 28 - (41 - 17) = 28 - 24 = 4 patrons with both a dog and a cat.

With these calculations, we can now fill out the two-way frequency table:

Patron\PetDogNo DogTotalCat41317No Cat17724Total212041

Note: The sum of the numbers for dog owners and non-dog owners must equal the total number of patrons, and the same applies for cat ownership.

Costs for standard veterinary services at a local animal hospital follow a normal distribution with a mean of $88 and a standard deviation of $24. what is the probability that one bill for veterinary services costs between $42 and $133?

Answers

the probability that one bill for veterinary services costs between $42 and $133 will be given as follows
P(42<x<133)
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus
when x=42:
z=(42-88)/24=-1.92
thus
P(x<42)=0.0281

when x=133
x=(133-88)/24=1.875
thus
P(x<133)=0.9699
Thus
P(42<x<133)
=0.9699-0.0281
=0.9418

Answer: 0.9418

Final answer:

There is a 94.25% probability that a bill for veterinary services costs between $42 and $133 in this local animal hospital, based on calculating Z-scores for $42 and $133 and finding the difference between probabilities.

Explanation:

The question pertains to the concepts of statistics, specifically the normal distribution which often appear in situations describing natural phenomena and social behavior. To solve this, we need to calculate the Z-scores for both values given and then look those Z-scores up in a standard normal distribution table, or use a calculator or software that can do this.

A Z-score is a statistical measurement that describes a value's relationship to the mean of a group of values. It's measured in terms of standard deviations from the mean.

If X is a random variable from a normal distribution with mean (µ) and standard deviation (σ), the Z-score is calculated by the formula Z = (X - µ)/σ.

For X =$42, Z1 = ($42 - $88)/$24 = -1.92 and for X=$133, Z2=($133-$88)/$24 = 1.88.

The probability that one bill for veterinary services costs between $42 and $133 equals the probability for Z values falling between -1.92 and 1.88. Refer to the standard normal distribution table or a calculator for the corresponding probabilities. The probability for Z1 equals approximately 0.0274, probability for Z2 equals approximately 0.9699. The required probability is then P(Z1

So, "there's a 94.25% chance that a bill for veterinary services costs between $42 and $133 in this local animal hospital".

Since the payment is made quarterly, it is made 4 times per year; therefore, [tex]k=4[/tex].
Since the type of the annuity is due, payments are made at the beginning of each period, and we know that we have 4 periods, so [tex]n=4[/tex].
Lets replace those values in our formula:

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

A teacher grades 25 students essays in 4 hours.

And, To find the time take him to grade 35 essays.

Now, Let us assume that,

Time take him to grade 35 essays is, x

Hence, We get;

25 / 4 = 35 / x

Solve for x;

x = 35 × 4 / 25

x = 5.6 hours

Determine the mean ,median,modes ,IQR,and rage for the data 3,8,6,6,4,6,9,9,12

Answers

Mean:

Add all the numbers:

3 + 8 + 6 + 6 +4 + 6 + 9 + 9 + 12 = 63

There are 9 numbers.

63 / 9 = 7

Mean = 7

Median:

Order all the numbers:

3, 4, 6, 6, 6, 8, 9, 9, 12

The median is 6.

Mode:

The number that appears the most is 6.

The mode is 6.

Inter-Quartile Range :

Median of 2nd part = 9

Median of 1st part = 5

Subtract:

9 - 5 = 4

The IQR is 4.

Range:

The highest number is 12. The lowest is 3

Subtract:

12 - 3 = 9

The range is 9.

Hope this helped☺☺

Mean=Average/add all the numbers and divide it by how many numbers there are

3+8+6+6+4+6+9+9+12

=63

63/9

=7 is your mean

Median=The middle number in a set of ordered numbers

first place all the numbers from least to greatest

3,4,6,6,6,8,9,9,12

The middle number of this set is 6 so 6 is your median

Mode is the most numbers repeated so if no numbers are repeated there is no mode

6 is repeated 3 times so 6 is your mode

Range: greatest number minus least number

12-3

=9 is your range

IQR=since the median is 6 we would split it and then minus it

so 3,4,6,6,6,8,9,9,12

It would be 9-5

=4is your IQR I am pretty sure that is correct!
