The four ways are :
If the value of V is quadrupledIf the value of radius (r) is halvedIf the value of V is enlarged 16 times and the value of r is doubledIf the values of V and r are quarteredWhat is cylinder?A cylinder is a 3-dimentional solid shape . It has two parallel bases which are joined by the curved surface. The cylinder has 2 circular bases one on the top and other at bottom and a curved region between them.
Important formulas of cylinder:
Base area of cylinder = π r²
Surface area of cylinder = 2 π r( r+ h)
Volume of cylinder = π r² h
where, h defines height and r defines the radius
According to ques , [tex]h= k\frac{V}{r^{2} }[/tex]
The four ways are :
1. when the value of volume V is quadrupled
i.e. V = 4V
then, h = [tex]k\frac{4V}{r^{2} }[/tex] = 4 ([tex]k\frac{V}{r^{2} }[/tex]) = 4h
2. when the value of radius (r) is halved
i.e. r = r/2
then , h = [tex]k \frac{V}{(\frac{r}{2} )^{2} }[/tex] = [tex]k\frac{4V}{r^{2} }[/tex] = 4 ([tex]k\frac{V}{r^{2} }[/tex]) = 4h
3. when the value of V is enlarged 16 times and the value of r is doubled
i.e. V= 16 V and r =2r
then, h = [tex]k \frac{16 V}{(2r)^{2}}[/tex] = [tex]k\frac{4V}{r^{2} }[/tex] = 4 ([tex]k\frac{V}{r^{2} }[/tex]) = 4h
4. If the values of V and r are quartered
i.e. V= V /4 and r =r/4
then, h = [tex]k \frac{(\frac{V}{4} ) }{(\frac{r}{4} )^{2} }[/tex] = [tex]k \frac{16 V}{(4r^{2})}[/tex] = [tex]k\frac{4V}{r^{2} }[/tex] = 4 ([tex]k\frac{V}{r^{2} }[/tex]) = 4h

For numbers 1 & 2, find the domain of the function in interval notation:
1.g(x)=13x-15/x+4
2.y=x2-10x+2
For numbers 3 & 4, solve the word problems:
3.The temperature in degrees Fahrenheit that is equivalent to a temperature in degrees Celsius is given by the function F(C)=95C+32. Find the temperature in degrees Fahrenheit that corresponds to a temperature of 15 degrees Celsius.
4.A ball is thrown in the air and its height after t seconds is given by the following function: h(t)=-16t2+32tHow high is the ball after 2 seconds?
1. The domain of the function in interval g(x) = 13x-15/x+4
Domain: (−∞,0)∪(0,∞),{x|x≠0
Range: (−∞,∞),{y|y∈R}
2. The domain of the function in interval y=x2-10x+2
Domain: (−∞,∞) {x|x∈R}
Range: (−23,∞),{y|y≥-23}
3. By rearranging the equation so that C is in terms of F, you may determine the inverse:
F= 5/9C+32
32 is deducted from both sides.
F−32= 5/9C
Add five to both sides:
5(F−32)=9C
multiply both sides by 9.
C= 5/9(F−32)
C=− 25/9
−2.78C o 2.dp
The inverse is, in fact, a one-to-one function.
4. We are looking for the height at t=0 in order to determine the beginning height. To do this, replace t with 0 and find h.
h(t)= -16t2 + 32t + 24
h(0) = -16(0)2 + 32(0) + 24
h(0) = 24
24 feet is the initial height
The constant in the equation often represents height. 24 in this instance.
The coefficient of x, in this case 32, represents the beginning velocity.
32 feet per second is the beginning velocity.

the height of a triangle is twice its base the area is 144cm³ find the base
Answer:
Base = 12cm
Height = 24cm
Step-by-step explanation:
Hello glittersplanet,
The formula for the area of a triangle is A = 1/2 b * h where A equals the area, b equals the base, and h equals the height. You are given the area in this problem.
Let the following conditions apply:
Base = x
Height 2x <-------Problem states the height is twice its base, correct?
Therefore:
A = 1/2 b*h
144 = 1/2 (x)(2x)
Simplify by removing the fraction by multiplying through by 1/2 and you are left with x^2 correct? Therefore:
144 = x^2
x = √144
x = 12
Therefore, base = x = 12 while height = 2x = 2(12) = 24
x = √144
Footing-x=12
Height-x2=24
Sean is exploring a coral reef 91 feet below sea level and liz is hiking 91 feet above sea level. Who is hiking farther away from sea level
They are about same distance from sea level.
Sean is exploring a coral reel below level= 91 feet
Liz is hiking above sea level= 91 feet
When, we compare both distance from sea level, both have the sane distance. Although, the distance between both Sean and Liz is 91+91= 182 feet.
When compare the level of both , both are at 91 feet one is below the sea level and another is above the sea level. Hence, both are at the same distance from the sea level.
Hence, the correct answer is both at 91 feet from seal level.

Write each equation in exponential form.
log 0.0001=-4
The exponential form of the given equation is 0.0001 = [tex]10^{-4}[/tex]
The exponential function is the inverse of the logarithmic function and vice versa. This means that the logarithm of a given number, say x, is the exponent to which another fixed number that is the base b, must be raised, so as to produce that number x. Mathematically this means,
logₐ x = y
then x = [tex]a^{y}[/tex]
Here, we are given a logarithmic function- log 0.0001 = -4
since no base is given, we always assume it to be 10
thus, the function can be written as- 0.0001 = [tex]10^{-4}[/tex]
Hence, the exponential form of this equation is 0.0001 = [tex]10^{-4}[/tex].

$57.96 is the value of each function after five years.
How does exponential growth utilise e?
e is the constant growth rate that all processes that are growing continuously share. With e, you may compare a simple growth rate—where all change occurs at the end of the year—with a compound, continuous growth rate, where growth occurs once per nanosecond or quicker.Let the principle sum be P
Let the number of years be n
Thus the total sum for n years is

Which function can be used to find the velocity at the bottom of the pendulum released from the same angle for any period, p?
A function which can be used to determine the velocity V(L(p)) at the bottom of the pendulum released from the same angle for any period, p is V(L(p)) = p/2π√192.08.
What is a function?A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable to an output variable.
Given the following data:
L(p) = 9.8(p/2π)².
V(L) = √19.6L
A function which can be used to determine the velocity V(L(p)) at the bottom of the pendulum released from the same angle for any period, p is given by:
V(L(p)) = √[19.6 × 9.8(p/2π)²]
V(L(p)) = √(19.6 × 9.8) × √(p/2π)²)

Moya is moving to a new house and packing up. She has 70 kilograms of books and 127 kg kilograms of clothing to send through the postal service. How much more do her clothes weigh than her books? How much is her shipping cost of she has to pay $80 per kg of books and $200 per kg of clothing?
The difference in her clothes and her books will be 57kg.
The difference in shipping cost if she has to pay $80 per kg of books and $200 per kg of clothing will be $19800.
How to calculate the value?From the information, Maya has 70 kilograms of books and 127 kg kilograms of clothing to send through the postal service, the difference in her clothes and her books will be:
= Weight of clothes - Weight of books
= 127 kg - 70 kg
= 57 kg
The difference in shipping cost if she has to pay $80 per kg of books and $200 per kg of clothing will be:
= 127(200) - 70(80)
= 25400 - 5600
