Describe the end behavior of a ninth-degree polynomial with a negative leading coefficient
Given:
The degree of polynomial = 9
Leading coefficient is negative.
To find:
The end behavior of the polynomial.
Solution:
Let the polynomial be P(x).
We have,
Degree of polynomial = 9, which is odd.
Leading coefficient is negative.
If the degree of a polynomial is odd and leading coefficient is negative, then
[tex]P(x)\to \infty\text{ as }x\to -\infty[/tex]
[tex]P(x)\to -\infty\text{ as }x\to \infty[/tex]
Therefore, the end behavior of the given polynomial is [tex]P(x)\to \infty\text{ as }x\to -\infty,P(x)\to -\infty\text{ as }x\to \infty[/tex].
The number of pounds that can be safely loaded onto an elevator, X, can be represented by
the inequality x < 1,200. Which number line correctly represents this inequality?
Answer:
the third one
Step-by-step explanation:
The inequality says X is less than 1200, this means the arrow needs to be pointing to the left. Because X cannot equal 1200, the circle on 1200 should not be filled in. It is only filled in if it is included.

Group of answer choices
y = –0.8x + 10
y = 0.8x – 10
y = 0.8x + 10
y = 5/7x + 10
Answer:
y = 0.8x – 10
This is the correct answer.
Step-by-step explanation:
Suppose a friend tells you she paid a total of $20,500 for a car, and you’d like to know the car’s list price (the price before taxes) so that you can compare prices at various dealers. Find the list price of the car if your friend bought the car in:
Roswell, where the sales tax is 6.5%
Given :
Total amount paid for the car is, A = $20,500.
Sales tax is 6.5%.
To Find :
The list price i.e. price without tax.
Solution :
Let, list price is P.
P = A - 0.65A
P = A( 1 - 0.65 )
P = 20500×( 1 - 0.065 )
P = $19167.5
Therefore, the list price of car is $19167.5 .

f(x)=6x+4. Find the inverse of f(x).
Answer:
c
Step-by-step explanation:
f(x)=6x+4
y=6x+4
x=6y+4
6y=x-4
y=(x-4)/6
f^-1(x)=(x-4)/6
Answer is Option-C
How to find Inverse Function:
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y.
(Here), Given
f(x) = 6x + 4
Let's inverse function be y.
y = 6x + 4
First step is to switch the positions of x and y.
Inverse: x = 6y + 4
x - 4 = 6y
=> y = (1/6) * (x - 4)

Answer:
8 hours and 54 minuter
Step-by-step explanation:
1 hour is equal to 60 minutes
we have 8 hours and 0.9 hours
0.9*60=54 minutes
we have 8 hours and 54 minuter
Answer:
The last one
Step-by-step explanation:
First you need to figure out how many minutes are in 0.1 hours
you can do this by dividing 60 minutes by 10
you get 6
multiply 6 and 9 so that you can find out how many minutes 0.9 hours are
this leaves you with 54 minutes
so your answer is 8 hours and 54 minutes
Two angle measures of this triangle are 60°. Which type of triangle is it?
Answer:
It's an equilateral triangle.
Step-by-step explanation:
For starters, the angle measures of any triangle all add up to 180 degrees. Because 2 sides of this triangle are 60 degrees, the two sides added up would be 120 degrees. Because 180 - 120 = 60, the unknown side is 60 degrees. Because an equilateral triangle is a triangle where all the angles or sides are equal, and all of the angle measures of the triangle are equal, it is an equilateral triangle.
A ball is launched into the sky at 54.4 feet per second from a 268.8 meter tall building. The equation for the ball’s height, h, at time t seconds is h = -3.2t^2 + 54.4t + 268.8. When will the ball strike the ground?
Answer:
7.41
Step-by-step explanation:
Vertical component:
S = 268.8
U = 0
V =?
A = 9.8
T=?
S = ut + 0.5at^2. u = 0
268.8 = 0.5x9. 8xt^2

Find the slope intercept equation of the line
Answer:
Step-by-step explanation:
slope-intercept formula looks like [y=mx + b]
use two points to find the slope.. or look at the graph carefully to see it there are easy points to count from.... hmmm
yes.. this is very easy to just count.. no math needed :P
the slope is posive. b/c the graph looks like you are walking up hill.. and it's rise over run is 2/1 .. so the slope is 2
then by looking at the graph I can also see that when x = 0 the line pass exactly thur +1.. sooo that tells me all I need to know for the sloop-intercept formula

Answer:
Below
Step-by-step explanation:
Always
Sometimes
Never
Always
Answer:
always,sometimes,never,always
Step-by-step explanation:
Equilateral triangles are
always
acute triangles. Yes, because acute is always 60 degrees, and equilateral is basically your average triangle, so its corners have 60 degrees.
Scalene triangles are
sometimes
acute triangles. Scalene triangles always dont have that sharp corner..they sometimes do, the sharp turn which is 60 degrees, ACUTE IS ALWAYS 60 DEGREES.
Right triangles are
never
acute triangles. A right angle cant be a acute, not 60 degrees..
Obtuse triangles are
always
isosceles triangles. Isosceles means atleast 2 of the sides look the same, i included how to recognize obtuse, right,etc

There are 500 cars in Frank's junkyard; 350 blue and 150 red. If Joe randomly selects 25 cars from his yard, what's the probability he'll get from 14 to 20 blue cars, inclusive? Could this be considered an almost binomial event?
A. P(x=14) + P(x=15) + P(x=16) + P(x=17) + P(x=18) + P(x=19) This is an almost binomial event.
B. binomcdf(25,.7,20) - binomcdf(25,.7,14) This is almost binomial event.
C. (25/14)(.7)^14(.3)^11 + (25/15)(.7)^15(.3)^10 + ... + (25/19) (.7)^19(.3)^6 + (25/20)(.7)^20(.3)^5 This is an almost binomial event

Which of these expressions equal 15 when x=1/2 and y=3? Circle all that apply. Please help with this my teacher need me to work out xy+3 1/2+20x Btw guys 3 1/2 are mixed numbers if your wondering
Answer:
15
Step-by-step explanation:
First you would replace the x and y's with 1/2 and 3.
So it would look like: (1/2) (3) + 3 1/2 + 20 (1/2)
Next, you go by PEMDAS (parenthesis, exponents, multiplications, division, addition, subtraction)
So you would first multiply and the parenthesis that I added mean multiplication.
1.5 + 3.5 + 10
So then all that is left to do is add because I multiplied everything out.
So it is 5 + 10 which is 15
