A cone has a base radius of 3 cm and a slant height of 5 cm.
Find h, the perpendicular height of the cone.

Answers

Answer 1

Answer:

h=4

Step-by-step explanation:

5²-3²=h²

h²=16

h=4cm

Answer 2

Answer:

I=4 (Slant height)

R=3 (Radius)

H=5 (slant height)

Step-by-step explanation:

Imagine inclination, peprendicular height and radius as a triangle, so this will have a 90 degrees angle and Pythagor theorem will imply to the calculations, as :

[tex]a^{2}+b^{2}= c^{2}\\[/tex]

where Height is A , Radius is B, and Inclination is C we have:

[tex]3^{2} +I^{2} = 5^{2}[/tex]

from above we have:

[tex]I^{2} =25-9[/tex]

and

[tex]\sqrt{I}=\sqrt{16} =4[/tex]

Question 13 I don’t know how to do it

Answers

Answer:

y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)

Step-by-step explanation:

The roots from the graph are

x = - 6 , then factor is (x + 6)

x = - 2 , then factor is (x + 2)

x = 1 ( multiplicity 2 ) , then factor is (x - 1)² then

y = a(x - 1)²(x + 2)(x + 6) ← a is a multiplier

To find a substitute any point on the graph into the equation

Using (0, - 3 ), then

- 3 = a(- 1)²(2)(6) = 12a ( divide both sides by 12 )

- [tex]\frac{1}{4}[/tex] = a

Then

y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)

Mr. Litterski creates a ball from rubber bands.



The circumference of the ball is 9.4 inches. What is the approximate surface area and volume of the ball? Round your answers to the nearest unit. HELP PLEASE!!

Answers

Answer:

The surface area of the ball is of 29 square inches.

The volume of the ball is of 15 cubic inches.

Step-by-step explanation:

The ball has an spherical format:

Circumference of a sphere:

The circumference of a sphere is 6.2832 times the radius.

Surface area

[tex]A = 4\pi r[/tex]

In which r is the radius.

Volume:

[tex]V = \frac{4\pi r^3}{3}[/tex]

The circumference of the ball is 9.4 inches.

So the radius is:

[tex]6.2832r = 9.4[/tex]

[tex]r = \frac{9.4}{6.2832} = 1.53[/tex]

Surface area

[tex]A = 4\pi(1.53)^2 = 29.3[/tex]

Rounding to the nearest unit, the surface area of the ball is of 29 square inches.

Volume:

[tex]V = \frac{4\pi (1.53)^3}{3} = 14.9[/tex]

Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.

Answers

Answer:  x = 3

Step-by-step explanation:

Subtract 1

 2^x = 8

Take the log.

 x·log(2) = log(8)

Divide by the coefficient of x.

 x = log(8)/log(2) = log₂(8)

We know that 8 = 2³, so log₂(8) = 3.

 x = 3

_____

If your equation is ...

 2^(x+1) = 9

then

 x + 1 = log(9)/log(2)

 x = log(9)/log(2) -1 . . . . . . change of base formula can be used, but isn't helpful unless you have a calculator that computes log₂(9).

 x ≈ 2.170

The value of x from the logarithmic equation is x = 3

What is Logarithm?

The power to which a number must be increased in order to obtain another number is known as the logarithm. A power is the opposite of a logarithm. In other words, if we subtract an exponentiation from a number by taking its logarithm

The properties of Logarithm are :

log A + log B = log AB

log A − log B = log A/B

log Aⁿ = n log A

Given data ,

Let the logarithmic equation be represented as A

Now , the value of A is

2ˣ + 1 = 9   be equation (1)

On simplifying the equation , we get

Subtracting 1 on both sides of the equation , we get

2ˣ = 8

Now , taking logarithm on both sides of the equation , we get

log ( 2 )ˣ = log ( 8 )

From the laws of logarithm , we can simplify

x log ( 2 ) = log ( 8 )

And , on further simplification , we get

x log ( 2 ) = log ( 2 )³

So , x log ( 2 ) = 3 log ( 2 )

Divide by log ( 2 ) on both sides of the equation , we get

x = 3

Hence , the value of x = 3

At the city Museum child admission is $6.20 an adult admission is $9.90 on Sunday 142 tickets were sold for a total sales of $1183.80 how much adult tickets were sold that day

Answers

Answer:

82

Step-by-step explanation:

Set the number of adult tickets sold as x. Then, the number of tickets for children would be 142-x

The total cost of all the tickets would be:

6.2(142 - x) + 9.9(x) = 1183.80

Simplify and solve

3.7x + 880.4 = 1183.8

3.7x = 303.4

x = 82

So, the answer is 82 tickets.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
time that the rocket will hit the ground, to the nearest 100th of second.
y = -16x^2+ 181x + 59

Answers

Answer:

The rocket will hit the ground after about 11.63 seconds.

Step-by-step explanation:

A rocket is launched from a tower. Its height y in feet after x seconds is modeled by the equation:

[tex]y=-16x^2+181x+59[/tex]

We want to determine the time at which the rocket will hit the ground.

If it hits the ground, its height y above the ground will be 0. So, we can set y = 0 and solve for x:

[tex]0=-16x^2+181x+59[/tex]

Solve the quadratic. Factoring is too tedious or impossible, and completing the square is also very tedious. So, we can use the quadratic formula:

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

In this case, a = -16, b = 181, and c = 59. Substitute:

[tex]\displaystyle x=\frac{-(181)\pm\sqrt{(181)^2-4(-16)(59)}}{2(-16)}[/tex]

Evaluate:

[tex]\displaystyle x=\frac{-181\pm\sqrt{36537}}{-32}[/tex]

Simplify:

[tex]\displaystyle x=\frac{181\pm\sqrt{36537}}{32}[/tex]

Hence, our solutions are:

[tex]\displaystyle x=\frac{181+\sqrt{36537}}{32}\approx 11.63\text{ or } x=\frac{181-\sqrt{36537}}{32}\approx-0.32[/tex]

Since time cannot be negative, we can ignore the second solution.

So, the rocket will hit the ground after about 11.63 seconds.

Nadia compares the weights, in grams, of some apples and oranges. She finds the median and interquartile range of the weights. Median Interquartile range (IQR) Apple sample 150 8 Orange sample 130 11 Answer the questions to compare the centers and variabilities of the samples. 1. Which sample has a greater typical value, or median? Write your answer in the space below. 2. Which sample has a greater variability, or spread? Write your answer in the space below. 3. According to these measures, is it possible that the heaviest piece of fruit in the two samples was an orange? Explain why or why not.

Answers

Answer:

The higher the interquartile range the bigger the variance as it the difference between the 0.25 and 0.75 quantiles. which basically means if the difference between the 25 percent and 75 percent is higher then there is more variety as they are further away.

Step-by-step explanation:

Which basically means if the difference between the 25 percent and 75 percent is higher then there is more variety as they are further away.

Would be amazing if you marked brainliest and feel free to comment any follow up questions ^^

The apple sample has a greater typical value or median.

The orange sample has a greater variability or spread.

No, it is not possible that the heaviest piece of fruit in the two samples was orange because the median weight of the orange sample is less than the median weight of the apple sample.

What is the interquartile range?

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

1.

The apple sample has a greater typical value or median, which is 150 grams, compared to the orange sample which has a median of 130 grams.

2.

The orange sample has a greater variability or spread as indicated by the interquartile range (IQR) of 11 grams, which is larger than the IQR of the apple sample which is 8 grams.

3.

No, it is not possible that the heaviest piece of fruit in the two samples was orange because the median weight of the orange sample is less than the median weight of the apple sample.

The median is a measure of central tendency and it indicates that at least half of the oranges weigh less than 130 grams, while at least half of the apples weigh more than 150 grams.

Therefore, it is more likely that the heaviest piece of fruit is an apple, not an orange.

However, we cannot be certain about this without knowing the actual weights of all the apples and oranges in the samples.

Thus,

The apple sample has a greater typical value or median.

The orange sample has a greater variability or spread.

No, it is not possible that the heaviest piece of fruit in the two samples was orange because the median weight of the orange sample is less than the median weight of the apple sample.

The word "vegan" (,begin bold,vee,end bold, gun) can refer to a particular kind of diet or the person who follows that diet. Vegans typically do not consume animal products, so their diets avoid meat, fish, poultry, eggs, or dairy products.

The animal and dairy products in a non-vegan diet provide important nutrients such as vitamin B12, calcium, and vitamin D. Vegans must find plant-based sources for these nutrients. For example, vegans can get vitamin B12 from fortified,superscript,1,baseline, breakfast cereals or foods made from soybeans. Many dark-green vegetables contain calcium; so do red beans and calcium-fortified fruit juices. Vegans can get vitamin D from fortified soy milk or rice milk. A healthy vegan diet includes a variety of fruits, vegetables, whole grains, nuts, seeds, and beans.People who want to switch to a vegan diet should start slowly.
