EXPLANATION
The volume of a right cylinder is given by the formula:
[tex]Volume = \pi \: {r}^{2} h[/tex]
From the given information, the height of the cylinder is 2 inches and the base radius is 14 inches.
This implies that, r=14 inches and r=2 inches.
We plug in the values into the formula to get;
[tex]Volume = \pi \times {14}^{2} \times 2[/tex]
[tex]Volume = \pi \times 196 \times 2[/tex]
[tex]Volume =392 \pi [/tex]

Can someone just explain pre-image and image to me?
Answer: in doing transformations, the pre-image is the image you start with. The task is to move the pre-image so that it is contiguous with the (target) image. This is typically done by translation, rotation or reflection or a combination of those moves.
Hope that helps
Step-by-step explanation:
Image is a related term of preimage. Preimage is a derived term of image.
In context terms the difference between preimage and image is that preimage is the set containing exactly every member of the domain of a function such that the member is mapped by the function onto an element of a given subset of the codomain of the function formally, of a subset b'' of the codomain ''y'' under a function ƒ, the subset of the domain ''x defined by while image is the subset of a codomain comprising those elements that are images of something.
As nouns the difference between preimage and image is that preimage is the set containing exactly every member of the domain of a function such that the member is mapped by the function onto an element of a given subset of the codomain of the function formally, of a subset b'' of the codomain ''y'' under a function ƒ, the subset of the domain ''x defined by while image is an optical or other representation of a real object; a graphic; a picture.

1 over the quantity x minus 3 times the quantity x plus 2
1 over the quantity x plus 4 times the quantity x minus 5
1 over the quantity x plus 2 times the quantity x minus 5
Answer:
The simplified form is 1 over the quantity x plus 2 times the quantity
x minus 5 ⇒ 1/(x+2)(x-5) ⇒ last answer
Step-by-step explanation:
* Lets write the product of the two fraction
∵ [tex]\frac{x+4}{x^{2}-3x-10} *\frac{x-3}{x^{2}+x-12}[/tex]
- At first factorize the denominators
# x² - 3x - 10
∵ x² = x × x ⇒ 1st term in the 1st bracket and 1st term in the
2nd bracket
∵ -10 = 2 × -5 ⇒ 2nd term in the 1st bracket and 2nd term in the
2nd bracket
∵ x × - 5 = -5x ⇒ ext-reams
∵ x × 2 = 2x ⇒ means
∵ 2x + -5x = -3x ⇒ middle term
∴ x² - 3x - 10 = (x + 2)(x - 5)
# x² + x - 12
∵ x² = x × x ⇒ 1st term in the 1st bracket and 1st term in the
2nd bracket
∵ -12 = -3 × 4 ⇒ 2nd term in the 1st bracket and 2nd term in the
2nd bracket
∵ x × 4 = 4x ⇒ ext-reams
∵ x × -3 = -3x ⇒ means
∵ 4x + -3x = x ⇒ middle term
∴ x² + x - 12 = (x - 3)(x + 4)
* Lets write the fractions after factorization
∴ [tex]\frac{x+4}{(x+2)(x-5)}*\frac{x-3}{(x-3)(x+4)}[/tex]
- lets simplify the fractions by cancel (x - 3) up with (x - 3) down
and cancel(x + 4) up with (x + 4) down
∴ [tex]\frac{1}{(x+2)(x-5)}*1=\frac{1}{(x+2)(x-5)}[/tex]

Using interval notation , identify the domain for the function!!! Math 3 - 10 points. Help needed
Answer:
The domain by the interval notation is (-∞ , 3)∪(3 , 4)∪(4 , ∞) ⇒ 3rd answer
Step-by-step explanation:
* Lets revise how to find the domain of the function
- The domain is all values of x that make the expression defined
- To find where the expression is undefined put the denominator
equal 0, to get the values of x which make denominator equal to 0
- The domain will be all the real number except those values
* Now lets solve the problem
∵ f(x) = (x² - 9)/(x² - 7x + 12)
- Let the denominator x² − 7x + 12 equal to 0
∵ x² − 7x + 12 = 0 ⇒ factorize it
- Consider the form x² + bx + c
- Find a pair of integers whose product is c and whose sum is b
- In this case, whose product is 12 and whose sum is −7
- They are -3 and -4
- Write the factored form using these integers.
∴ (x -3)(x - 4) = 0 ⇒ put each bracket = 0
∴ x - 3 = 0 or x - 4 = 0
∵ x - 3 = 0 ⇒ add 3 to both sides
∴ x = 3
∵ x - 4 = 0 ⇒ add 4 to both sides
∴ x = 4
∴ The domain of f(x) is all real number except 3 and 4
* The domain by the interval notation is
(-∞ , 3)∪(3 , 4)∪(4 , ∞)
Suppose θ is an angle in the standard position whose terminal side is in Quadrant IV and . Find the exact values of the five remaining trigonometric functions of θ.
If [tex]\theta[/tex] falls in quadrant IV, then we know [tex]\sin\theta<0[/tex] and [tex]\cos\theta>0[/tex]. By definition of cosecant,
[tex]\csc\theta=\dfrac1{\sin\theta}[/tex]
so we also know that [tex]\csc\theta<0[/tex]. Recall that
[tex]\cot^2\theta+1=\csc^2\theta[/tex]
which means
[tex]\csc\theta=-\sqrt{\cot^2\theta+1}=-\dfrac{\sqrt{10}}3[/tex]
[tex]\implies\sin\theta=-\dfrac3{\sqrt{10}}[/tex]
By definition of cotangent,
[tex]\cot\theta=\dfrac{\cos\theta}{\sin\theta}\implies\cos\theta=\dfrac1{\sqrt{10}}[/tex]
[tex]\implies\sec\theta=\sqrt{10}[/tex]
We also immediately know that
[tex]\tan\theta=-\dfrac{21}7[/tex]
The listed answers are unsimplified relative to the ones we've come up with here, but with some manipulation we find
[tex]\sin\theta=-\dfrac3{\sqrt{10}}=-\dfrac{7\cdot3}{7\sqrt{10}}=-\dfrac{21}{\sqrt{490}}[/tex]
[tex]\cos\theta=\dfrac1{\sqrt{10}}=\dfrac7{7\sqrt{10}}=\dfrac7{\sqrt{490}}[/tex]
[tex]\csc\theta=\dfrac1{\sin\theta}=-\dfrac{\sqrt{490}}{21}[/tex]
[tex]\sec\theta=\dfrac1{\cos\theta}=\dfrac{\sqrt{490}}7[/tex]
[tex]\tan\theta=\dfrac1{\cot\theta}=-\dfrac{21}7[/tex]
so that the third option is correct.
The surface area of a sphere having a diameter of 8 inches is:
64 is the correct answer
Answer: [tex]A = 201.06\ in^2[/tex] or [tex]A = 64\pi\ in^2[/tex]
Step-by-step explanation:
The surface area of a sphere is calculated by the following formula
[tex]A = 4\pi r^2[/tex]
Where r is the radius of the sphere
In this case we know that the diameter d of the sphere is
[tex]d=8\ inches[/tex]
So the radius r is:
[tex]r=\frac{d}{2}\\\\r=\frac{8}{2}\\\\r=4\ inches[/tex]
So the surface area of the sphere is:
[tex]A = 4\pi (4)^2[/tex]
[tex]A = 64\pi[/tex]
[tex]A = 201.06\ in^2[/tex]

If angle EGD=38 degrees, what is angle IGJ?
Answer :FDG AND IGJ
Step-by-step explanation: Since EGF is 90 degrees then and EGD equals 38 degrees you need to subtract 38 from 90 and you are left with 52 degrees for angle FGD. The alternate interior angle to FGD is IGJ which would make the angles congruent.
The measure of angle IGJ is 38 degrees.
Let's derive the measure of angle IGJ step by step:
Given: Angle EGD = 38 degrees
To find: Angle IGJ
In triangle IGJ, we know that the sum of the interior angles is 180 degrees. Therefore, we can write:
Angle I + Angle G + Angle J = 180 degrees
Now, let's focus on angle G. Angle G is opposite to angle EGD in triangle EGD. According to the angle opposite to the side in a triangle theorem (or the angle opposite to the side is equal in a triangle theorem), we can say:
Angle G = Angle EGD
Given that Angle EGD = 38 degrees, we have:
Angle G = 38 degrees
Now, let's substitute this value into the equation for triangle IGJ:
Angle I + 38 degrees + Angle J = 180 degrees
Now, let's isolate angle I and angle J by subtracting 38 degrees from both sides:
Angle I + Angle J = 180 degrees - 38 degrees
Angle I + Angle J = 142 degrees
Now, we have an equation relating angle I and angle J. However, we need more information to determine the measure of either angle. But, we know that the sum of the angles in triangle IGJ is 180 degrees. Therefore, we can conclude that:
Angle I + Angle G + Angle J = 180 degrees
Angle I + 38 degrees + Angle J = 180 degrees
Angle I + Angle J = 180 degrees - 38 degrees
Angle I + Angle J = 142 degrees
Since the sum of angles I and J is 142 degrees, and we know that angle G is 38 degrees, the remaining angle (IGJ) must be equal to angle G:
Angle IGJ = Angle G = 38 degrees
Therefore, the measure of angle IGJ is 38 degrees.

Kim made soup which contains 75 total ounces of beans
The soup has two kinds of beans ; black and red
There are 4 times as many ounces of black beans as red beans
How many ounces of red beans are in the soup?
Answer:
15 ounces of red beans
Step-by-step explanation:
So, we know Kim's soup contains a total of 75 ounces of beans, including red beans (r) and black beans (b), so r + b = 75
Then we know that for each ounce of red beans, there are 4 ounces of black beans, 1b = 4r
Then we merge both equations by replacing b's value in the first equation by its equivalent (b = 4r), since we are looking for the count of red beans.
r + b = 75
r + 4r = 75
5 r = 75
r = 15
There are 15 ounces of red beans in Kim's soup, that looks a lot like the last chili I made :-)

The probability of grabbing a diet soda and a snack bag of Cheetos is 42%.
The question is asking to find the probability of selecting a diet soda and a bag of Cheetos at a party. To calculate this probability, we need to look at the total number of each item and determine how many favorable outcomes there are based on the selections made.
Calculate the total number of sodas: 12 diet sodas + 8 regular sodas = 20 sodas.Calculate the probability of selecting a diet soda: P(diet soda) = 12 diet sodas / 20 total sodas = 0.6 or 60%.Calculate the total number of snack bags: 14 bags of Cheetos + 6 bags of pretzels = 20 snack bags.Calculate the probability of selecting a bag of Cheetos: P(Cheetos) = 14 bags of Cheetos / 20 total snack bags = 0.7 or 70%.Finally, calculate the probability of both events happening together, which is the product of the individual probabilities: P(diet soda and Cheetos) = P(diet soda)what steps can you use to make your nails grow faster

shen is fertilizing his garden. the garden is in the shape of a rectangle. its length is 12 feet and its width is 10 feet. suppose each bag of fertilizer cover 30 square feet. how many bags will he need to cover the garden?
12x10=120 now 120x30=3,600 so your answer is 3600
The area of Shen's rectangular garden is 120 square feet. Given that a bag of fertilizer covers 30 square feet, Shen will need 4 bags of fertilizer to cover his garden.
Explanation:This question relates to the area of a rectangle and unit conversion. The area of a rectangle can be calculated by multiplying its length and its width. In this case, the garden is a rectangle with a length of 12 feet and a width of 10 feet. By multiplying these two dimensions, we get an area of 120 square feet.
A single bag of fertilizer covers 30 square feet. To calculate the number of bags required to cover the garden, we can divide the total area of the garden (120 square feet) by the area that one bag of fertilizer can cover (30 square feet).
So, 120 ÷ 30 = 4. Therefore, Shen will need 4 bags of fertilizer to cover his garden.
