There was a study done on oxygen consumption of snails as a function of pH, and the result was a degree 4 polynomial whose graph is shown.

Which of the following statements about this function is INCORRECT?​

There Was A Study Done On Oxygen Consumption Of Snails As A Function Of PH, And The Result Was A Degree

Answers

Answer 1

Answer:

A. There is a positive leading coefficient

Step-by-step explanation:

Answer 2

Polynomials can be represented as an equation or graphs.

The incorrect option is: (b) There is a positive leading coefficient.

The polynomial has a degree of 4; this means that the degree of the polynomial is even.

So option (a) The degree of the polynomial is even is true

From the graph, we can see that the function decreases at (7<x<8) and (9<x<10)

This means that, the function decreases at two intervals

So option (d) There are two intervals where the function is decreasing is also true

Also, the function is at maximum at x = 7 and x = 9.

This means that:

Option (c) At two pH values, there is a relative maximum value

Hence, the incorrect option is:

(b) There is a positive leading coefficient.

This is so because, the graph decreases at some points on the graph.

This means that, the graph has a negative leading coefficient.

Properties of Exponential Function for Roots.

[tex]a^{\frac{m}{n}}=\sqrt[n]{a^m}[/tex]

The first one is wrong as 4^1/2 would equal √4 = 2

The second choice is correct.

The third choice is correct because ∛8 = 2 and √4 also = 2

The fourth choice is wrong because √8 = 2√2

The fifth choice is also wrong because 2^1/2 would be √2 while √32 is 2^5

The sixth choice is 3^3/2 which would equal √27 = 3√3 which is correct.

What are coordinate plane?

A coordinate plane is a tool used for graphing points, lines, and other objects.

Some real life applications are:

Digital World

In this, any PDF file we open are created according to 2-D coordinates (x, y), all the concepts like distances, slopes and trigonometry are applicable in this.

Location of Air Transport

In this, air traffic are mainly managed by coordinates study, to find the location of a particular location for any change in location of a plane it is used.

Map Projections

The points usually provides the frame of references for your data, to locate the position on the surface of earth.

GPS

We use GPS for any specific location identifier on the earth which we get in the form of coordinates, these are points showing the asked location.

Latitude and Longitude

These are the parameter used to locate any specific point on the earth, Latitude and Longitude are always defined by a point, they constitute a coordinates system to identify any geographical location.

2x - y = 8
x + 3y = 4​

Answers

Answer:

x = 4, y = 0

Step-by-step explanation:

Two find x and y, we can simply solve one of the two equations for one of the variables, and substitute it into the other.  That will provide one of the two values, which can then be plugged into either equation for the other value.  Let's do it:

[tex]2x - y = 8\\y = 2x - 8\\\\x + 3y = 4\\x + 3(2x - 8) = 4\\x + 6x - 24 = 4\\7x = 28\\x = 4\\\\y = 2x - 8\\y = 2(4) - 8\\y = 0[/tex]

So x is equal to four, and y is equal to zero.

Use the Divergence Theorem to calculate the surface integral


S
F · dS;
that is, calculate the flux of F across S.
F(x, y, z) = x2yi + xy2j + 3xyzk,

S is the surface of the tetrahedron bounded by the planes x = 0, y = 0, z = 0, and
x + 4y + z = 4.

Answers

Answer:

[tex]\frac{56}{15}[/tex]

Step-by-step explanation:

Given that [tex]\vec F(x, y, z) = x^2y \hat i + xy^2 \hat j + 3xyz \hat k[/tex]

F(x, y, z) = x^2y \hat i + xy^2 \hat j + 3xyz \hat k

The flux of \vec F across the surface S is given by

[tex]\int \int _s \vec F \cdot dS[/tex]

Where the survare S is the surface of the tetrahedron bounded by the planes x = 0, y = 0, z = 0, and  x + 4y + z = 4.

Now, by using the Gauss Divergence theorem:

[tex]\int \int _s \vec{F} \cdot dS=\int \int \int _v \bigtriangledown \cdot \vec F dV[/tex]...(i)

where V is the volume enclosed by the surface S and [tex]dV=dxdydz[/tex]

\bigtriangledown \cdot \vec F = \hat i \frac {\partial \vec F}{\partial x}+\hat j \frac {\partial \vec F}{\partial y}+\hat k \frac {\partial \vec F}{\partial z}

=2xy+2xy+3xy=7xy

Putting this value in equation (i), we have

\int \int \int _v \bigtriangledown \cdot \vec F dV = \int \int \int _v (7xy)dxdydz

= [tex]7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y} \left( \int_{z=0}^{z=4-x-4y}xy\;dz\right)dxdy[/tex]

[tex]=7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y} xy(4-x-4y-0)dxdy \\\\=7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y}(4xy-x^2y-4xy^2)dxdy \\\\=7\int_{y=0}^{y=1} (2x^2y-\frac 1 3 x^3y-2 x^2y^2)|_{x=0}^{x=4-4y}dy \\\\[/tex]

[tex]=7\int_{y=0}^{y=1} (2(4-4y)^2y-\frac 1 3 (4-4y)^3y-2 (4-4y)^2y^2)dy[/tex]

[tex]=7\int_{y=0}^{y=1} (32(1-y)^2y-\frac {64}{3} (1-y)^3y-32(1-y)^2y^2)dy[/tex]

[tex]=7\int_{y=0}^{y=1} (32(1-2y+y^2)y-\frac {64}{3} (1-y^3-3y+3y^2)y-32(1-2y+y^2)y^2)dy[/tex]

[tex]=7\int_{y=0}^{y=1} \{32(y-2y^2+y^3)-\frac {64}{3} (y-y^4-3y^2+3y^3)-32(y^2-2y^3+y^4)\}dy[/tex]

[tex]=7 \{32(\frac 1 2 y^2- \frac 2 3 y^3+\frac 1 4 y^3)-\frac {64}{3} (\frac 1 2 y^2-\frac 1 5 y^5-y^3+\frac 3 4 y^4)-32(\frac 1 3 y^3-\frac 1 2 y^4+\frac 1 5 y^5)\} |_{y=0}^{y=1}[/tex]

[tex]=7 \{32(\frac 1 2 - \frac 2 3 +\frac 1 4 )-\frac {64}{3} (\frac 1 2 -\frac 1 5 -1+\frac 3 4 )-32(\frac 1 3 -\frac 1 2 +\frac 1 5 )\}[/tex]

[tex]=7\times \frac {8}{15} \\\\=\frac{56}{15}[/tex]

Hence, the flux of F across S is [tex]\frac{56}{15}[/tex].
