How do I describe the end behavior, determine if it's an odd or even degree, and the real number of zeros? Please help me.
Answers
Answer:
1. Even Degree
2. 6 zeros
Step-by-step explanation:
Determine if it’s an odd or even degree:—
- The graph is shown approach positive infinity when both sides of x-values, negative and positive, both approach their respective infinity sides.
To put it simply, see when both negative x-values and positive x-values approach their negative or positive infinity, the y-values will always be positive, even if negative x-values approach negative infinity.
For a polynomial function to be an even degree, it must satisfy the following:—
[tex]\displaystyle \large{ \lim_{x \to \pm \infty} f(x) = \infty}[/tex]
As an odd degree, either negative or positive x-values will approach positive infinity or negative infinity, depending on the function itself.
From the graph, we can say that the function is an even degree.
__________________________________________________________
Summary I
Even-Odd Degree
Even Degree, when both sides of x-value approach their respective infinity, y-value will always approach positive infinity.
Odd Degree, one side of y-value will approach positive infinity and another will approach negative infinity.
__________________________________________________________
Determine numbers of zeros:—
- We can determine numbers of zeros by examining x-axis and the graph. How many times does the graph intersect or pass through x-axis? Count and you should get 6 intercepts.
Therefore, there are 6 real solutions/zeros for this function/equation.
__________________________________________________________
Summary II
Determine zeros
To determine or check how many solutions or zeros do the graph/function/equation has, you can use the graph method. Simply count how many times does the graph pass through x-axis and x-intercepts are zeros.

[tex]\left[Here\; your \;Answer\; below}\right][/tex]
Answer:
7
Step-by-step explanation:
Given;
Kyle has 13 notebooks (1 for each class) and he puts 5 stickers on each one
Solve;
If Kyle wants to put 5 stickers on each of his 13 classroom notebooks, then we simply multiply 5*13 to find out how many stickers he will use in total.
5 * 13 =65
Kyle used 65 stickers total.
Then, to find out how many sheets he used, we will simply divide the total amount of stickers (T) by the amount of stickers on a sheet (S).
T = 65
S = 10
65/10 = 6.5
Thus, He will need 7 sheets, but will only use 6 and a half sheets.

The z-probability for the condition -0.78 ≤ z ≤ 1.16 is 66%.
What is a z-score?
A z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.
It is given that
-0.78 ≤ z ≤ 1.16
We have to find the p-value corresponding to -0.78 ≤ z ≤ 1.16.
This means, p(-0.78 ≤ z ≤ 1.16)
p(0.78≤ z ≤1.16) can be written as p(z ≤ 1.16) - p(z ≤ -0.78)
p(0.78≤ z ≤1.16) = p(z ≤ 1.16) - (1-p(z ≤ 0.78))
p(0.78≤ z ≤1.16) = p(z ≤ 1.16) -1 + p(z ≤ 0.78)
From the standard normal table,
p(z ≤ 1.16)=0.87698
p(z ≤ 0.78)=0.78230
So, p(0.78≤ z ≤1.16)= 0.87698-1+0.78230
p(0.78≤ z ≤1.16) = 0.65928≈0.66 i.e 66%
Therefore, the z-probability for the condition -0.78 ≤ z ≤ 1.16 is 66%.

The school drama club sold 2,400 tickets to a play and made $9,000 from the ticket sales. Student tickets,
X, were $3 and adult tickets, y, were $5.
Create a system of two equations to represent this situation.
Answers
Hi!
Given:
total tickets = 2,400 total profit = 9,000student tickets cost $3adult tickets cost $5x = student ticketsy = adult ticketsThe first equation we can make can use the total number of tickets. The total number of tickets would be equal to the number of student tickets plus the number of adult tickets, correct? Therefore:
[tex]x+y=2400[/tex]
Now, the second one can use the profit and the price of each ticket. The number of student tickets multiplied by 3 (for the price) plus the number of adult tickets multiplied by 5 would be equal to the total profit. Hence:
[tex]3x+5y=9000[/tex]
Therefore, your system of equations is:
[tex]x+y=2400[/tex]
[tex]3x+5y=9000[/tex]

Step-by-step explanation:
since the polynomial is in the form
+x² - nx - m
we know that we are looking for 2 factors of x (to create x²).
and they must be in the form of
(x + a)(x - b)
to create the negative "m" at the end.
and "b" must be larger than "a" to create the negative "n" in the middle.
let's do the multiplication and compare the parts with our actual expression :
(x + a)(x - b) = x² - bx + ax - ab = x² + (a - b)x - ab
so, we know now in numbers that
-ab = -44
ab = 44
and
a - b = -7
a = b - 7
the short solution here is trial and error with the factors of 44 :
44 = 1×44 = 2×22 = 4×11
ah, only one combination has a difference of the factors of 7 or -7 : 4 and 11.
since b has to be larger (as a - b = -7), we have a = 4 and b = 11
and the factorization of our original expression is
f(x) = (x + 4)(x - 11)
FYI
if there is not such a short list of options to try, we can also go the full formal way :
we can use the second equation as identity in the first equation and get
(b - 7)b = 44
b² - 7b = 44
b² - 7b - 44 = 0
by the way, it is not surprising that it looks the same way as the original expression in x, because the factorization uses exactly the zero solutions for the original expression.
anyway, the formal solution to a quadratic equation of
ax² + bx + c = 0 is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = b (the variable of our equation above)
a = 1
b = -7
c = -44
b = (7 ± sqrt((-7)² - 4×1×-44))/(2×1) =
= (7 ± sqrt(49 + 176))/2 = (7 ± sqrt(225))/2 =
= (7 ± 15)/2
b1 = (7 + 15) / 2 = 22/2 = 11
b2 = (7 - 15) / 2 = 8/2 = 4
based again on the original equations and the fact that b has to be the larger number, we get again (of course) that b1 is the valid solution and
b = 11 and a = 4

The rectangles length is ______ feet, and its width is_____feet.
Answers
Answer:
length= 108 feet,
width= 50 feet
Overview of steps:
Define variablesForm two equations using given informationSolve for one variable through substitution/ eliminationSolve for the other variable through substitutionWorking:
Let the length and the width of the rectangle be L and W feet respectively.
L= 2W +8 -----(1)
Perimeter= 2(length) +2(width)
316= 2L +2W
2L +2W= 316
Divide both sides by 2:
L +W= 158 -----(2)
Substitute (1) into (2):
2W +8 +W= 158
Simplify:
3W +8= 158
3W= 158 -8
3W= 150
Divide both sides by 3:
W= 150 ÷3
W= 50
Substitute W= 50 into (1):
L= 2(50) +8
L= 100 +8
L= 108
Thus, the rectangle's length is 108 feet, and its width is 50 feet.

What is an Arithmetic Progression?An arithmetic progression(A.P.) is a series, where the difference between consecutive numbers is constant.
The first term of an A.P. is denoted by a, and the common difference is denoted by d.
The nth term of an A.P. series is found using the formula:
aₙ = a + (n-1)d.
The sum of n terms of an A.P. series is found using the formula:
Sₙ = (n/2)(2a + (n-1)d)
How do we solve the given question?We are said that every tree is equally spaced. So the distance between the trees is in arithmetic progression.
With the first tree being at 0 feet from itself, our a = 0.
The distance from the first tree to the sixth tree is 60 feet, so we can say that the 6th term is 60
6th term = a + 5d
or, 60 = 0 + 5d
or, d = 60/5 = 12 feet.
To find the distance between the first tree and the last tree(12th tree), we will find the 12th term of the series,
12th term = a + (12-1)d = 0 + 11(12) = 132 feet.
∴ The distance in feet between the first and last tree is 132 feet.
