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).

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:

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]".

Thus the approach above is appropriate.

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:

7t + 8

Step-by-step explanation:

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.

Using proportional relations, it is found that:

-------------------------------

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]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.
