Find the height of a cylinder with a volume of 36pie cm with an exponent of 3 and a base with a radius of 3 cm.h = ???cmv \: is \: 36\pi \: cm ^{3}vis36πcm3r \: is \: 3cmris3cm
Data
Volume = 36 cm3
radius = 3 cm
Formula
Volume of a cylinder = pi x r2 x h
Solve for h
h = Volume / (pi x r2)
Substitution
h = 36 / (3.1416 x (3)2)
Simplification
h = 36 / (3.1416 x 9)
h = 36 / 28.2744
Result
height = 1.27 cm
Bud Graham owns property in Salinas assessed at $250,000 and pays a property tax rate of $1.96 per $100 of assessed value. He also owns property in Modesto assessedat the same $250,000 and pays property tax at a rate of $21.50 per $1,000 of assessed value. What is Bud's total property tax bill for properties in both towns?$10,275$9,965$11,045$10,996None of these choices are correct.
Ok so first we are gonna calculate the tax bill for each town independently and then we are gonna add their values. The tax rate in Salinas is $1.96 per $100 of assessed value and we know Mr. Graham's property is assessed at $250000 so we can use the rule of three:
$100-----------$1.96
$250000----------x
Where x represents his property tax bill for Salinas. According to the rule of three:
[tex]x=\frac{250000\cdot1.96}{100}=4900[/tex]So he has to pay $4900 in taxes for that property. Now we make the same process for his property on Modesto:
$1000-----------$21.5
$250000----------x
[tex]x=\frac{250000\cdot21.5}{1000}=5375[/tex]So he has to pay $5375 for his property in Modesto. Adding the two bills we know the total property bill: $4900 + $5375 = $10275

To find the limit we need to rationalize the function, we achieve this by multiplying by a one written in an appropiate way:
[tex]\begin{gathered} \lim_{h\to0}\frac{2-\sqrt{4+h}}{h}=\lim_{h\to0}\frac{2-\sqrt{4+h}}{h}\cdot\frac{2+\sqrt{4+h}}{2+\sqrt{4+h}} \\ =\lim_{h\to0}\frac{(4-(\sqrt{4+h})^2)}{h(2+\sqrt{4+h})} \\ =\lim_{h\to0}\frac{4-(4+h)}{h(2+\sqrt{4+h})} \\ =\lim_{h\to0}\frac{4-4-h}{h(2+\sqrt{4+h})} \\ =\lim_{h\to0}\frac{-h}{h(2+\sqrt{4+h})} \\ =\lim_{h\to0}\frac{-1}{2+\sqrt{4+h}} \\ =-\frac{1}{2+\sqrt{4+0}} \\ =-\frac{1}{2+\sqrt{4}} \\ =-\frac{1}{2+2} \\ =-\frac{1}{4} \end{gathered}[/tex]Therefore:

EXPLANATION
Given that the slant represents the diagonal side of a solid, we can use the Pythagorean Theorem as shown as follows:
Thus, if we know the height and the base, we can compute the slant height by the Pythagorean as explained above.
The Pythagorean Theorem says:
Therefore, we can substitute the radius and the height in the Pytagorean Equation to obtain the slant height.
[tex]\text{radius}^2+\text{height}^2=\text{slant height\textasciicircum{}2}[/tex][tex]r^2+h^2=s^2[/tex]Pluggin in the given values into the equation:
[tex]5^2+7^2=s^2[/tex]Isolating the slant height:

Thus, the surface area is:
[tex]Total\text{ Surface Area=}\frac{SurfaceArea_{\text{sphere}}}{2}+Surface\text{ Area of the Cone}-\text{ Surface Area of the Base}[/tex]Replacing terms:
[tex]=\frac{4\cdot\pi\cdot r^2}{2}+(\pi rs+\pi r^2)-\pi r^2[/tex]We can apply the same reasoning to the Volume:

Okay, here we have this:
Considering the provided function, we are going to replace the coordinate pairs one by one in the function, to observe which of the pairs maximizes the function, so we obtain the following:
(6, 5):
p=22x+14y
p=22(6)+14(5)
p=132+70
p=202
(0,0):
p=22x+14y
p=22(0)+14(0)
p=0+0
p=0
(0, 12):
p=22x+14y
p=22(0)+14(12)
p=0+168
p=168
(15, 0):
p=22x+14y
p=22(15)+14(0)
p=330+0
p=330
(11, 13):
p=22x+14y
p=22(11)+14(13)
p=242+182
p=424
Finally we obtain that the corner point that maximizes the function p=22x+14y is the last option (11, 13).

Cooper, Sha'NiyaThe sum of three consecutive integers is 177. What is the largest of the integers, and why?
We can represent the sum of the three consecutive integers as:
[tex]n+(n+1)+(n+2)=177[/tex]Then, we need to solve the equation for n, then:
[tex]3n+3=177_{}\Rightarrow3n=177-3\Rightarrow3n=174\Rightarrow n=\frac{174}{3}\Rightarrow n=58[/tex]Then, the largest of the integers is n + 2 or 58 +2 = 60.
The reason is that the other integers are 58, 58 + 1 = 59, that is, 58 and 59.
We can check that:
58 + 59 + 60 = 177.
Divide (41°48') = 4.
The division of 41°48' by 4 gives the result 10°27'.
What is termed as the division?Multiplication is the inverse of division. If 3 groups of 4 add up to 12, 12 divided into 3 equal portions adds up to 4 in each group in division. Each component of a division eqn has its own name.Dividend: A dividend is indeed the number divided during the division process.Divisor: The divisor is the number in which the dividend is divided.Quotient: A quotient is an outcome of the division process.Remainder: We can't always divide things exactly. There could be an extra number. The leftover number is known as the remainder.The following describes the relationship between such four parts:
Dividend = Divisor x Quotient + Remainder
For the given expression,
(41°48') divided by 4.
= 41°48' / 4
= 10°27'.
Thus, the division of the expression 41°48' by 4 gives 10°27'.

V is the midpoint of UW. If UV = 2x and VW = x + 8,what is UV?
Please explain and show work
Based on the definition of the midpoint of a line segment, the length of UV is determined as: 16 units.
What is the Midpoint Definition of a Segment?The midpoint of a segment is defined as the point on a line segment where the line segment is bisected into two equal smaller segments. The length of the smaller segments formed will be equal to each other.
Given that V is the midpoint of segment UW, it means that V divides segment UW into two equal smaller segments, UV and VW.
UV = 2x
VW = x + 8
Therefore:
UV = VW
Substitute
2x = x + 8
2x - x = x + 8 - x [subtraction property of equality]
x = 8
Find the length of UV:
