Answer:
Step-by-step explanation:
In this sense "area" refers to a geographical area in which people may or may not live; any "population" refers to the group of people living in a specific area. We might discuss the "population" of the "Los Angeles area," which refers to people living within the geographic boundaries of the City of Los Angeles.
"Urban" characterizes a given area where the land is thickly settled with human residents (as opposed to open, commercial or rural land). Most of the area within the boundaries of "Los Angeles" are "urban."
"Density" refers to "population density," defined as the number of people per square mile (or other measure of area); as an example we might refer to the population density of the City of Los Angeles, and that reasure might be in the area of "246,000 residents per square mile."

how would i do number 2?
Answer:
m=2
Step-by-step explanation:
When you put a number into the inverse of a function (f^-1) you get the original number back.
Ex: f^-1(11) = (11-3)/2 = 4
f(4) = 2×4+3 = 11
So, f(-5)=-2
So, when x is -5,
f(x) = -2
f(x)=m(-5)+8
-2=m(-5) + 8
m=2

You can use the formula [tex]\frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex] with a pair of points [tex](x_{1},y_{1})[/tex][tex](x_{2},y_{2})[/tex]. We can use points (1,4) and (-4,-4). Plugging in the equation we get (4-(-4))/(1-(-4)), which simplifies to 8/5, which is the slope.
in which number does the digit 5 have a value that is 10 times as great as the digit 5 in the number 4.59?
Answer:
B) 2775.9
Step-by-step explanation:
The missing options are:
A) 578
B) 2775.9
C) 134.591
D) 31.757
The digit 5 is in the tenths in 4.59. This means that its value is 0.5. A value 10 times greater is 10*0.5 = 5, that is, a 5 in the ones, like in 2775.9.

Answer:
[tex]\alpha=1-0.98 =0.02[/tex]
And [tex]\alpha/2 0.01[/tex], the degrees of freedom are given by:
[tex] df= n-1= 25-1=14[/tex]
Then the critical value using the t distribution with 24 degrees of freedom is:
[tex] t_{\alpha/2}= \pm 2.492[/tex]
And the best solution would be:
0 -2.492
Step-by-step explanation:
For this problem we know that the sample size is n = 25. The confidence level is 98% or 0.98 then the significance would be:
[tex]\alpha=1-0.98 =0.02[/tex]
And [tex]\alpha/2 0.01[/tex], the degrees of freedom are given by:
[tex] df= n-1= 25-1=14[/tex]
Then the critical value using the t distribution with 24 degrees of freedom is:
[tex] t_{\alpha/2}= \pm 2.492[/tex]
And the best solution would be:

Answer:
A
Step-by-step explanation:
Using the recursive formula with a₁ = 5 , then
a₂ = 2a₁ - 7 = 2(5) - 7 = 10 - 7 = 3
a₃ = 2a₂ - 7 = 2(3) - 7 = 6 - 7 = - 1

-((-7) +(4)(-12)+(-3)(11)+(-2))
Answer:
90
Step-by-step explanation:
-((-7) + 4 × (-12) + (-3) × 11 + (-2))
-(-7 + 4 × (-12) + (-3) × 11 + (-2))
-(-7 - 48 - 33 - 2)
-(-90) → 90
Final Answer - 90
Hope this helped! :)
Answer:
90
Step-by-step explanation:
Recall Order of Operations rules that require that computations inside parentheses must be done first. Next, multiplication be done before addition or subtraction.
-((-7) +(4)(-12)+(-3)(11)+(-2)) can be re-written as
- ((-7) +(4)(-12)+(-3)(11)+(-2)), which in turn becomes:
-( -7 - 48 - 33 - 2 ), or
-( -55 - 35), or
- (-90), or 90
Use what you know about zeros of a function and end behavior of a graph to choose the graph that matches the function f(x)=(x-2)(x-1)(x-4)
Answer:
The last one
Step-by-step explanation:
The zeros of a function f(x) are the values of x such that f(x)=0. Since the coordinate y equals f(x), we must look for the values where y=0 (x-intersect).
Since f(x) is factorized, f(x)=0 only when one of its factors equals zero.
So we have
f(x) = 0 ===> x+2 = 0 OR x+1 = 0 OR x+4 = 0
and we have
x = -2 or x = -1 or x = -4
Hence the function must intersect the x-axis at these points.
The only graph that matches the requirements is the last one.

The sum of eight times a number, and 8, is equal to seven times the number
Write the above sentence as an equation
Answer:
8x+8=7x
Step-by-step explanation:
The variable is supposed as x where ever the exact number is not mentioned.
n*8 + 8 = n*7 --> the answer must be n = -8 because:
8n + 8 = 7n
8n - 8n + 8 = 7n - 8n
8 = -1n
-8 = n

there are 1600 students in school.47.5% are male.how many are female
Answer:
840 female students
Step-by-step explanation:
The total percentage of students is 100%, so, the percentage of female students = 100% - 47.5%
=52.5%
Multiply the total no. of students by the percentage to get the no. of female students.
1600 x 52.5%
= 840 female students
You can also obtain the same answer by first multiplying the male percentage to find the no. of male students, then subtracting it from the total 1600.
What equation could be used to find the missing leg length a in a right triangle with a hypotenuse of 60 and leg length of 51?
Answer:
Pythagorean Theorem: a² + b² = c² should be used.
Step-by-step explanation:
51² + b² = 60²

What is the inverse of a function?The inverse function of a function f(x) in mathematics is a function that reverses the operation of f(x).
The given function in the question:
f(x) = (x/3) - 2
f(x) + 2 = x/3
x + 2 = f⁻¹(x)/3
f⁻¹(x) = 3(x + 2)
Hence, the inverse of the given function is f⁻¹(x) = 3(x + 2).

We khow that the equation of a circle is written this way :
(x-a)²+(y-b)²=r² where (x,y) are the coordinates of the cercle's points and (a,b) the coordinates of the cercle's center and r the radius .
Our task is to khow the values of a and b :

Hey there! :)
Answer:
Choice B.
Step-by-step explanation:
Since h(x) equals (g o f)(x):
f(x) is substituted for x in the equation g(x). We can go through the answer choices and choose the most suitable choice by substitution:
A. f(x) = x, g(x) = x/ x + 1
(g o f)(x) = x / x + 1. This is incorrect.
B. f(x) = x², g(x) = x / x + 1
(g o f)(x) = x² / x² + 1. This matches h(x), so this is correct.
C. f(x) = x + 1, g(x) = 1/x²
(g o f)(x) = 1/(x² + 2x + 1). This is incorrect.
D. f(x) = x + 1, g(x) = x²
(g o f)(x) = x² + 2x + 1. This is incorrect.
Therefore, B is the correct answer.

Answer:
(a) Local Maximum (x,y) = (0,12)
Local Minimum (x,y) = (-9,6) (smaller x-value)
Local Minimum (x,y) = (6,3) (Larger x-value)
(b) Increasing = [tex](-9,0)\cup (6,\infty)[/tex]
Decreasing = [tex](\infty,-9)\cup (0,6)[/tex]
Step-by-step explanation:
(a)
Local Maximum: The function gives maximum value in small neighborhood.
From the given graph it is clear that the maximum value of the function is 12 at x=0. So,
Local Maximum (x,y) = (0,12)
Local Minimum: The function gives minimum value in small neighborhood.
It is clear that the minimum value of the function is -6 and 3 at x=-9 and x=6. So,
Local Minimum (x,y) = (-9,6) (smaller x-value)
Local Minimum (x,y) = (6,3) (Larger x-value)
(b)
The function is increasing on -9<x<0 and after 6.
Increasing = [tex](-9,0)\cup (6,\infty)[/tex]
The function is decreasing on 0<x<6 and before -9.
Decreasing = [tex](\infty,-9)\cup (0,6)[/tex]
If sin(21°) = 0.36, and cosθ = 0.36, what's the measure of ∠θ? ANSWERS: A) m∠θ = 21° B) m∠θ = 0.36° C) m∠θ = 90° D) m∠θ = 69°
Hey there! :)
Answer:
m∠θ = 69°.
Step-by-step explanation:
If sin (21°) = 0.36 and cos θ = 0.36, the two angles are complementary because the sine and cosine values are equivalent. Therefore:
90 - 21 = 69°.
The correct answer is D) m∠θ = 69°.

How many non-congruent triangles can be formed by connecting 3 of the vertices of the cube?
Answer:
The number of non-congruent triangles that can be formed by connecting 3 of the vertices of the cube is 3 non-congruent triangles
Step-by-step explanation:
From the three dimensional shape of a cube, triangles can be constructed from;
1) 6 side faces
2) 4 front face to opposite vertices triangles
3) 4 rear face to opposite vertices triangles
Each face can produce ₄C₃ = 4 triangles
Therefore;
The total number of triangles that can be formed = 4 × 6 + 4 × 4 + 4 × 4 = 56 triangles
Of the 56 triangles, it will be found that all 24 triangles from the different 6 direct faces will have the same dimension of 1, 1, √2 are congruent
The 24 triangles formed by the sides of the faces and an adjacent diagonal have the same dimension of 1, √2, √3 and are congruent
The 8 triangles formed by joining the three diagonals have the same dimension of √2, √2, √2 are congruent
Therefore, the 56 triangles comprises of a combination of three non-congruent triangle.
There are only 3 observed non congruent triangles formed by connecting three of the vertices of the cube.
