The following correctly refers to the last element in the array of integers called numbers:
numbers[length of numbers-1].
An array is a collection of items, which can be of the same type and stored in contiguous memory. Once an array is created, its size cannot be altered during program execution. The last element in an array of integers called numbers can be referred to using numbers[length of numbers-1]. This is because array indexing starts from zero and the length of an array is the number of elements it contains, but indexing ends at length-1. Therefore, the last element in an array is always at the index length-1.It is important to note that array indexing is an error-prone area of programming, and one should always ensure that indices do not go out of bounds. This can lead to memory access violations and undefined behavior. A good practice is to use loops that start from 0 and end at length-1 when iterating over an array, to ensure that all elements are processed. It is also advisable to use constants or symbolic names to represent array indices, to make the code more readable and easier to maintain.
In summary, an array is a collection of items that can be stored in contiguous memory and cannot be resized during program execution. The last element in an array of integers called numbers can be referred to using numbers[length of numbers-1]. Array indexing is an error-prone area of programming, and one should always ensure that indices do not go out of bounds.

Whats steps do I need to make to solve the equation: How do I solve for a?
2B=ha-qa
Answer:
2B/( h-q)=a
Step-by-step explanation:
2B=ha-qa
Factor out an a
2B=a(h-q)
Divide each side by ( h-q)
2B/( h-q)=a(h-q)/( h-q)
2B/( h-q)=a
Answer:
a = [tex]\frac{2B}{h-q}[/tex]
Step-by-step explanation:
Given
2B = ha - qa ← factor out a from each term
2B = a(h - q) ← divide both sides by (h - q)
[tex]\frac{2B}{h-q}[/tex] = a
A man has a 100-acre ranch that he wishes to stock with cows and sheep. Cows require ten acres of grazing land per animal and sheep require three acres of grazing land per animal. If he wishes to fully utilize the land, how many ways are there to stock the ranch so that it includes at least one cow and at least one sheep?
Answer:
3 ways
Step-by-step explanation:
From the question:
Number of acres of the land = 100 acres
1 cow = 10 acres of land
1 sheep = 3 acres of land
To fully utilize the land, the number of ways to stock the ranch so that it includes at least one cow and at least one sheep is calculated as:
1) 1 cow and 30 sheep
1 cow × 10 acres + 30 sheep × 3 acres
10 + 90 = 100 acres
2) 4 cows and 20 sheep
4 cow × 10 acres + 20 sheep × 3 acres
40 + 60 = 100 acres
3) 7 cows and 10 sheep
7 cow × 10 acres + 10 sheep × 3 acres
70 + 30 = 100 acres
Therefore, to fully utilize the land, the number of ways to stock the ranch so that it includes at least one cow and at least one sheep is 3 ways

Simplify (-64)2/3.
Answer:
As a proper fraction. (numerator smaller than denominator): 2/3 = 2/3
As a decimal number: 2/3 ≈ 0.67.
As a percentage: 2/3 ≈ 66.67%
That's all I can provide
The value of the expression (-64)^(2/3) can be simplified as 16.
Given an expression (-64)^(2/3).
We have to find the value of the expression.
We have the rules of exponents that,
aᵇⁿ = (aᵇ)ⁿ
Using this rule, the expression can be written as,
(-64)^(2/3) = (-64²)^(1/3)
= (4096)^(1/3)
Now,
(a)^(1/3) is equal to ∛a.
(-64)^(2/3) = ∛4096
= 16
Hence the correct option is B.

What’s the median of
17,11,10,5,2
Answer:
the mean is 9
Step-by-step explanation:
please help if you can! :)
Answer:
B
Step-by-step explanation:
We have the function:
[tex]f(x)=x^2-5x[/tex]
And we are given that:
[tex]f(n)=-4[/tex]
And we want to find the value of n such that this is true.
So, let's substitute f(x) for -4 and x for n. This yields:
[tex]-4=n^2-5n[/tex]
Let's solve for n. First, add 4 to both sides:
[tex]n^2-5n+4=0[/tex]
This is a quadratic. We can solve by factoring:
[tex](n-1)(n-4)=0[/tex]
Zero Product Property:
[tex]n-1=0\text{ or } n-4=0[/tex]
Solve for n for each equation:
[tex]n=1\text{ or }n=4[/tex]
So, n can be either 1 or 4.
Our of our answer choices, the correct answer is B.

A ball is thrown in the air from the top of a building. Its height, in meters above ground, as a function of time, in seconds, is given by h(t)=−4.9t2+21t+6. How long does it take to reach maximum height?
Answer:
we have to find the derivate of that function which is: -4.9*2t +21 and to find the maximum height this derivate should be equal to 0
-9.8t+21=0 so
t=21/9.8=2.14

The formula c = 5p + 210 relates c, the total cost in dollars of hosting a birthday party at a skating rink, to p, the number of people attending. If Allie's parents are willing to spend $350 for a party, how many people can attend?
Answer:
28 people
Step-by-step explanation:
Plug in 350 as c into the equation, since c is the total cost:
c = 5p + 210
350 = 5p + 210
Solve for p:
140 = 5p
28 = p
So, 28 people can attend

What is an equation of the line that passes through the points (6, -5) and (3,0)?
Step-by-step explanation:
Hey there!
The equation of a st.line passing through points (6,-5) and (3,0) is;
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
[Using double point formula]
Now, Put all values,
[tex](y + 5) = \frac{0 + 5}{3 - 6} (x - 6)[/tex]
Simplify it to get equation.
[tex](y + 5) = - \frac{5}{3} (x - 6)[/tex]
[tex]3(y + 5) = - 5(x - 6)[/tex]
[tex]3y + 15 = - 5x + 30[/tex]
[tex]5x + 3y + 15 - 30 = 0[/tex]
[tex]5x + 3y - 15 = 0[/tex]
Therefore the required equation is 5x + 3y - 15 = 0.

Answer:
y = -5/3x + 5
Step-by-step explanation:
The formula for the equation of a line is :
y - y1 = m (x-x1)
m is the gradient
finding the gradientformula
[tex]\frac{y2-y1}{x2-x1} \\\\[/tex]
= (0--5)/ (3-6)
=5 / -3
gradient = - 5/3
inserting the values in formula for the equation of a line
y - y1 = m (x-x1)
y - -5 = -5/3 (x - 6 )
y + 5 = -5/3 x + 10
y = -5/3x + 10 - 5
y = -5/3x + 5

Given the coordinates S(-3,6) and T(4, -8). Find the equation of the line that passes through the two points and write the equation in slope-intercept form. (y=mx + b)
Answer:
m=slope
y= intercept
m=y2-y1 /x2-x1 -8 - 6= -14
4- -3 = 7
-14/7 a 2 is your slope
y=2x=b
Now we find for X
choose a y from one of your points : lets use 6 Plug 6 in for y s(-3,6)
y=2x+b
6=2(-3) +b
now solve for b
6= -6 + b
now add 6 to both sides to get b alone
6+6 =6+-6 +b
12=b
now write you equation out y=2x =12

Find the GCF of this statement
33x? +88x – 110x
Answer:
I think 11
Step-by-step explanation:
11 goes in to 33 88 and 110 evenly
Answer:
11x
Step-by-step explanation:
Each term has 'x' so we know that we can factor out the 'x'. Then we are left with
x(33+88+110)
All three of the numbers inside the parenthesis are divisible by 11. So we will get
11x(3+8+10)
There are no more common factors so 11x is the GCF.
