The degree of a polynomial is given by the higher exponent of the variable.
In this polynomial, we have terms with the variable with exponents 6, 0, 1 and 9.
Therefore the degree of the polynomial is 9.
The leading coefficient is the number that multiplies the variable with a higher exponent.
The leading term is 18u^9, so the leading coefficient is 18.

450 students are graduating. 68% are going to college. 14% are working. How many students are unsure about what to do?
ANSWER
81 students
EXPLANATION
We have that 450 students are graduating.
68% (out of 100%) are going to college while 14% (out of 100%) are working.
To find the percentage of the studetns that are unsure about what to do, we have to subtract the percentages of those that know what to do from 100%.
That is:
100 - (68 + 14)
=> 100 - 82
=> 18%
Therefore, 18% of people are unsure about what to do.
Now, to find the number of students, we multiply this percent by the total number of students (450):
[tex]\begin{gathered} \frac{18}{100}\cdot450 \\ =\text{ 81} \end{gathered}[/tex]81 students are unsure about what to do.

For us to be able to determine the distance along an arc on the surface of the earth, we will be using the following formula:
[tex]\text{ S = r}\theta[/tex]Where,
S = arc length
r = radius (radius of the earth)
θ = central angle (in radian)
Given:
r = 3960 miles
θ = 48 mins.
a.) Let's convert the given measure of the central angle to radian.
[tex]\theta=48mins.\text{ = (48 mins.) x }\frac{1^{\circ}}{(60\text{ mins.})}\text{ = }\frac{48}{60}(1^{\circ})[/tex][tex]\theta\text{ = }\frac{4}{5}^{\circ}[/tex][tex]\text{ }\theta_{radian}\text{ = }\theta_{degrees}\text{ x }\frac{\pi}{180^{\circ}}[/tex][tex]\text{ }\theta_{radian}\text{ = }\frac{4}{5}\text{ x }\frac{\pi}{180}\text{ = }\frac{4\pi}{900}\text{ = }\frac{\pi}{225}\text{ radians}[/tex]b.) Let's now determine the distance (arc length).
[tex]\text{ S = r}\theta[/tex][tex]\text{ S = (3960)(}\frac{\pi}{225}\text{ ) = }\frac{3960\pi}{225}\text{ miles = 17.6}\pi\text{ miles = 55.2920307 }\approx\text{ 55.292 miles}[/tex]Therefore, the answer is 55.292 miles.

Given systemx + 2y = 5 x² + y² = 25Rearrange the first equationx = 5 - 2y Substitute the value of x into second equation(5 - 2y)² + y² = 254y² - 20y + 25 + y² = 255y² - 20y = 0y² - 4y = 0y(y - 4) = 0y = 0 and y = 4Find the value of xy = 0 ⇒ x = 5 - 2*0 = 5y = 4 ⇒ x = 5 - 2*4 = -3Answer:
[tex](x,y)=\left(\; \boxed{-3,4} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]
[tex](x,y)=\left(\; \boxed{5,0} \; \right)\quad \textsf{(larger $x$-value)}[/tex]
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}\;x+2y=5\\x^2+y^2=25\end{cases}[/tex]
To solve by the method of substitution, rearrange the first equation to make x the subject:
[tex]\implies x=5-2y[/tex]
Substitute the found expression for x into the second equation and rearrange so that the equation equals zero:
[tex]\begin{aligned}x=5-2y \implies (5-2y)^2+y^2&=25\\25-20y+4y^2+y^2&=25\\5y^2-20y+25&=25\\5y^2-20y&=0\end{aligned}[/tex]
Factor the equation:
[tex]\begin{aligned}5y^2-20y&=0\\5y(y-4)&=0\end{aligned}[/tex]
Apply the zero-product property and solve for y:
[tex]5y=0 \implies y=0[/tex]
[tex]y-4=0 \implies y=4[/tex]
Substitute the found values of y into the first equation and solve for x:
[tex]\begin{aligned}y=0 \implies x+2(0)&=5\\x&=5\end{aligned}[/tex]
[tex]\begin{aligned}y=4 \implies x+2(4)&=5\\x+8&=5\\x&=-3\end{aligned}[/tex]
Therefore, the solutions are:
[tex](x,y)=\left(\; \boxed{-3,4} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]
[tex](x,y)=\left(\; \boxed{5,0} \; \right)\quad \textsf{(larger $x$-value)}[/tex]

In the front of a building there are three doors each to be painted
a different color from 10 different available colors. How many color
arrangements for the doors are there?
In this case, the order doesn't matter and the colors cant be repeated.
Now, we need to use the permutation formula:
[tex]P(n,r)=\frac{n!}{(n-r)!}[/tex]Where n represents the total different available colors and r is equal to
the number of doors.
Replacing on the permutation formula:
[tex]P(10,3)=\frac{10!}{(10-3)!}[/tex][tex]P(10,3)=\frac{10!}{7!}[/tex][tex]P(10,3)=\frac{10x9x8x7!}{7!}[/tex][tex]P(10,3)=10x9x8![/tex]Then

Mary is 4 years older than Sue. If the sum of their ages is 16. How would you set up the equations?
Answer:
A. x=y-4, x+y=16
C. x=y-4, x+y=16
Explanation:
• Let Sue's age = x
Mary is 4 years older than Sue, therefore:
• Mary's age, y = x+4
[tex]\begin{gathered} y=x+4 \\ \implies x=y-4 \end{gathered}[/tex]Next, the sum of their ages is 16. This gives:
[tex]x+y=16[/tex]Therefore, the equation is:
[tex]\begin{gathered} x=y-4 \\ x+y=16 \end{gathered}[/tex]The correct choices are A and C.
Generalize Two data sets have the same number of values. The first data set has a mean of 7.2 and a standard deviation of 1.25. The second data set has a mean of 7.2 and a standard deviation of 2.5. Which data set is more spread out?
ANSWER
The second data set is more spread out
EXPLANATION
The standard deviation measures the spread of a data distribution. The more spread out a data distribution is, the greater its standard deviation.
In this problem, the second data set has twice the standard deviation of the first data set, so it's more spread out.

The points (x,y) whose values satisfy the equation -5y=13 belong to the graph of that equation.
First, isolate y by dividing both sides of the equation by -5 and simplifying:
[tex]\begin{gathered} -5y=13 \\ \Rightarrow\frac{-5y}{-5}=\frac{13}{-5} \\ \Rightarrow y=-\frac{13}{5} \end{gathered}[/tex]Then, the points (x,y) belon to the graph of the equation -5y=13 whenever the value of y is -13/5, regardless of the value of x. Then, choose two different values of x to find two points that belong to the graph. For example, x=0 and x=2. Then, this two points belong to the graph:
[tex]\begin{gathered} (0,-\frac{13}{5}) \\ (2,-\frac{13}{5}) \end{gathered}[/tex]Notice that -13/5=-2.6,
Plot the points (0,-2.6) and (2,-2.6) in a coordinate plane:

The length of the side rectangle perpendicular to the river is and the length of the side of the rectangle parallel to the river is.What is the maximum area?
The dimensions that will maximize the area are x = 354 ft and y = 708 ft
The length of the side rectangle perpendicular to the river is 354 ft
The length of the side of the rectangle parallel to the river is 708 ft
The maximum area = 250632 ft²
Explanation:Given:
The length of the fencing = 1416 ft
The length of the side rectangle perpendicular to the river = x
To find:
The dimensions that will maximize the area
To determine the dimensions, we will make an illustration of the given information:
let the length o the rectangle parallel to the river = y
Length of the for the enclosed area = Perimeter of the enclosed area
Perimeter of the enclosed area = x + x = y = 2x + y
[tex]1416=2x+y\text{ . . .\lparen1\rparen}[/tex]Area of the rectangle = length × width
length = y, width = x
let the Area of the rectangle = A(x)
[tex]A(x)\text{ = xy . . . \lparen2\rparen}[/tex]To get the expression for A(x), we will make y the subject of the formula in equation (1):
y = 1416 - 2x
substitute for y in equation (2):
[tex]\begin{gathered} A(x)\text{ = x\lparen1416 - 2x\rparen} \\ \\ A(x)\text{ = 14166x - 2x}^2 \end{gathered}[/tex]To get the maximum dimension, we will differentiate with respect to x:
[tex]\begin{gathered} A^{\prime}(x)\text{ = 1416 - 4x} \\ \\ At\text{ maximum, A'\lparen x\rparen = 0:} \\ 1416\text{ - 4x = 0} \\ 1416\text{ = 4x} \\ x\text{ = }\frac{1416}{4} \\ x\text{ = 354} \end{gathered}[/tex]substitute for x in equation (1):
[tex]\begin{gathered} 1416\text{ = 2\lparen354\rparen + y} \\ 1416\text{ - 708 = y} \\ y\text{ = 708} \end{gathered}[/tex]The dimensions that will maximize the area are x = 354 ft and y = 708 ft
The length of the side rectangle perpendicular to the river is 354 ft
The length of the side of the rectangle parallel to the river is 708 ft
The maximum area = 354 × 708
