Answer: 16

Answer:

Up left, down right

Step-by-step explanation:

First, polynomials with odd degrees will have end behaviors in two different directions.

Since the leading coefficient is negative, the end behavior will be up left and down right.

So, the end behavior is up left, down right.

The end behavior of a 9th-degree polynomial with negative leading coefficients is up left, downright.

We have to determine

The end behavior of a 9th-degree polynomial with a negative leading coefficient??

If the leading coefficient is negative and the exponent of the leading term is even, the graph falls to the left and right.

The equation of the 9th-degree polynomial is;

[tex]\rm x^9+3x^8+4x^7+x^6+x^5+9x^3+2x^2+x+1=0[/tex]

The degree of the polynomial is 9 which is odd.

Hence, the end behavior of a 9th-degree polynomial with negative leading coefficients is up left, downright.

The graph for the given slope of 8 and includes the point (0,2) is given below.

Given that, the line that has a slope of 8 and includes the point (0,2).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Substitute m=8 and (x,y)=(0, 2) in y=mx+c, we get

2=8(0)+c

c=2

Put m=8 and c=2 in y=mx+c, we get

y=8x+2

Graph the line using the slope and y-intercept, or two points.

Slope: 8

y-intercept: (0,2)

Coordinate points are (0, 2) and (1, 10)

Hence, the graph for the given slope of 8 and includes the point (0,2) is given below.

Step-by-step explanation:

[tex]f(3)[/tex] means that the value of x is 3. Insert this into the equation for x, but DO NOT insert the value into f(x). To not get confused, remember that f(x) is basically y. You can insert y into the equation to not get mixed up:

[tex]f(x)=(3)^3-2\\\\or\\\\y=3^3-2[/tex]

Now simplify the equation, starting with exponents (PEMDAS):

[tex]x^3=x*x*x\\\\3*3*3\\\\9*3=27\\\\f(x)=27-2\\\\or\\\\y=27-2[/tex]

Simplify subtraction:

m= -1.3

Step-by-step explanation:

subtract 3.4 from both side and than simplify

The equation of this line in slope intercept form is y = 1.5x + 13.

The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis.

Equation of line: y = mx + c

where m is slope of line and c is the y intercept.

[tex]\frac{y+2}{x+10} = \frac{3}{2}\\ \\ 2(y+2) = 3(x+10)\\\\2y + 4 = 3x + 30\\\\2y = 3x + 26\\\\y = 1.5x + 13\\\\where\ slope = 1.5\ and\ y\ intercept\ is\ (0,13)[/tex].

Answer:

First Picture: Length = 30.82in

Second Picture: Length = 34.64in

Step-by-step explanation:

Given

Picture 1:

Area = 950in²

Picture 2:

Area = 1200in²

Required

Determine the length of each pictures

From the question, we understand that both pictures are square in shape and the area is calculated as thus:

Area = Length²

For the first picture, substitute 950 for Area

This gives:

950 = Length²

Length ² = 950

Take square root of both sides

Length = √950

Length = 30.8220700148448822

Length = 30.82 (approximated)

Hence, the length of the first picture is 30.82in

For the second picture, substitute 1200 for Area

This gives:

1200 = Length²

Length² = 1200

Take square root of both sides

Length = √1200

Length = 34.6410161513775458

Length = 34.64 (approximated)

Hence, the length of the second picture is 34.64in

Answer:

There are 10 dogs in the kennels

Step-by-step explanation:

The equivalent fraction relationship between the number of dogs and cats in the kennels is 1/2.

Which means, if [tex]n_d[/tex] the number of dods and [tex]n_c[/tex] is the number of cats, then,

[tex]\frac {n_d}{n_c}=\frac{1}{2}\cdots(i)[/tex]

Given that there are 20 cats, so [tex]n_c=20.[/tex]

Now, from equation (i) we have,

[tex]\frac {n_d}{20}=\frac{1}{2}[/tex]

[tex]\Rightarrow n_d=\frac{1}{2}\times 20[/tex]

[tex]\Rightarrow n_d= 10[/tex].

Hence, there are 10 dogs in the kennels.
