The formula for the surface area of a cylinder with radius r and height h is at times twice the product of the
radius and height plus twice the product of t and the square of the radius. Translate this verbal expression into
an algebraic expression.
Answer:
[tex]2\pi \: rh + 2\pi {r}^{2} = 2(t \times {r}^{2} )[/tex]
Step-by-step explanation:
The TSA of the cylinder
[tex]2\pi \: rh + 2\pi {r}^{2} [/tex]
In Mathematics, 'is' is =
Twice means 2( )
Product means ×
So we have
[tex]2\pi \: rh + 2\pi {r}^{2} = 2(t \times {r}^{2} )[/tex]
as the answer.
Find the volume of the following solid. Using cylindrical coordinates
z = 4 - 4(x^2 + y^2)
z = (x^2 + y^2)^2 -1
In cylindrical coordinates, the equations of the surfaces become
[tex]z = 4 - 4r^2 \\\\ z = (r^2)^2 - 1 = r^4 - 1[/tex]
These surfaces intersect on the cylinder of radius 1 with cross sections parallel to the x,y-plane:
[tex]4 - 4r^2 = r^4 - 1 \\\\ \implies r^4 + 4r^2 - 5 = (r-1)(r+1)(r^2+5) = 0 \\\\ \implies r=1[/tex]
Then in cylindrical coordinates, the volume of the space bounded by these surfaces is
[tex]\displaystyle \int_0^{2\pi}\int_0^1\int_{r^4-1}^{4-4r^2}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta = 2\pi \int_0^1 \int_{r^4 - 1}^{4-4r^2}r\,\mathrm dz\,\mathrm dr \\\\ = \pi \int_0^1 (4-4r^2)^2 - (r^4-1)^2 \,\mathrm dr \\\\ = \pi \int_0^1 (15-32r^2+18r^4-r^8)\,\mathrm dr = \boxed{\frac{352\pi}{45}}[/tex]

Answer and Step-by-step explanation:
This graph is a One to One Function.
For a function to be one-to-one, each x value must have its own y-value, which is the case for this graph.
The y value of a point where a vertical line intersects a graph represents an output for that input x value. If you draw a vertical line on the graph, and it intersects more than once, then the graph does not define as a function because that x value has more than one output (y).

The relationship between adult dog weight x in pounds and the daily recommended amount of dog food y in cups is proportional.
Write an equation for the relationship. How much dog food is recommended for a 25- pound adult dog?
please help me
no links or files
thank you !
Using proportional relations, it is found that:
The equation for the relationship is [tex]\frac{x}{60}[/tex].[tex]\frac{5}{12}[/tex] cups is recommended for a 25- pound adult dog.-------------------------------
The amount of cups of food y is proportional to the weight of a dog, which is of x pounds, and thus, the following equation models the situation:
[tex]y = cx[/tex]
In which c is the constant of proportionality.
-------------------------------
[tex]\frac{1}{6}[/tex] of a cup is needed to feed a dog of 10 lbs.This means that when [tex]x = 10, y = \frac{1}{6}[/tex]This is used to find c.[tex]y = cx[/tex]
[tex]\frac{1}{6} = 10c[/tex]
[tex]60c = 1[/tex]
[tex]c = \frac{1}{60}[/tex]
Thus, the equation for the relationship is:
[tex]y = \frac{x}{60}[/tex]
-------------------------------
The amount of cups needed for a 25-pound dog is y when x = 25, thus:
[tex]y = \frac{25}{60} = \frac{5}{12}[/tex]
[tex]\frac{5}{12}[/tex] cups is recommended for a 25- pound adult dog.

plz someone help I will mark brainlest diameter is 8.8 yd
Answer:
60.79 square yards.
Step-by-step explanation:
d = 2r; d = 8.8.
8.8 = 2r
r = 8.8 / 2
r = 4.4 yards.
Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.
4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.
Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.

Find the third term in the expansion of (a+b)^9 in the simplest form
Answer:
[tex]The\ third\ term\ is\ \boxed{36a^7b^2}\\[/tex]
Step-by-step explanation:
[tex]\left(\begin{array}{c}9\\ 1\end{array}\right)=\dfrac{9}{1} =9\\\\\left(\begin{array}{c}9\\ 2\end{array}\right)=\dfrac{9*8}{2*1} =36\\\\\\(a+b)^9=a^9+\left(\begin{array}{c}9\\ 1\end{array}\right)a^8b+\left(\begin{array}{c}9\\ 2\end{array}\right)a^7b^2+....+b^9\\\\\\The\ third\ term\ is\ \boxed{36a^7b^2}\\[/tex]
The given expression is:
[tex](a+b)^9[/tex]According to the question,
→ [tex]\binom{9}{1} = \frac{9}{1}[/tex]
[tex]= 9[/tex]
→ [tex]\binom{9}{2} = \frac{9\times 8}{2\times 1}[/tex]
[tex]= \frac{72}{2}[/tex]
[tex]= 36[/tex]
Now,
→ [tex](a+b)^9 = a^9+\binom{9}{1}a^8b+\binom{9}{2}a^7b^2+...+b^9[/tex]
hence,
The third term is "[tex]36a^7b^2[/tex]".
