hi :) how to do question 7 ?
Answer:
Step-by-step explanation:
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 :
We khow that the center is lying on the line 3x+2y=16⇒ 2y=-3x+16⇒ y= [tex]\frac{-3}{2}[/tex]x+8 We khow that the points P and Q are two points in the cercle Let Ω be the center of this cercle we can notice that : PΩ AND QΩ are both equal to the radius ⇒ PΩ=QΩ= rSo let's write the expression of this distance using vectors KHOWING THAT Ω(a,b)Vector PΩ(a-4,b-6) and Vector QΩ(a-8,b-2) PΩ=[tex]\sqrt{(a-4)^{2}+(b-6)^{2} }[/tex] and QΩ=[tex]\sqrt{(a-8)^{2}+(b-2)^{2} }[/tex] Let's substitute a by x and b by y PΩ=QΩ we substitute each distance by its expression After simplyfying the expressions we get finally : -12+8x-8y=0 now we have -12x +8x-8y=0 and the line equation 3x+2y-16=0 these are simultanious equations so after solving them we get x=3.8 wich is approximatively 4 and y=2 we substitute a by 4 and y by 2 in PΩ to get the radius we get r = [tex]\sqrt{(4-4)^{2}+(2-6)^{2} }[/tex] = 4 so r²= 16 then the equation is : (x-4)²+(y-2)²=16how to find the gradient of the line segment joining each pair points?

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.

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]
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.

(c) The years in which economists have deemed the U.S. to be in recession. (d) The category which best describes how frequently a person eats chocolate: Frequently, Occasionally, Seldom, Never. (e) The Temperature (in degrees Fahrenheit) of patients with pneumonia.
Answer:
(a) Nominal
(b) Nominal
(c) Interval
(d) Nominal
(e) Interval
Step-by-step explanation:
There are four distinct level of measurements: nominal, ordinal, interval and ratio.
(a)
Majors of randomly selected students at a university.
Level of measurements: nominal
Because in case of nominal level of measurements the variables are classified using names, labels, alpha numeric data, and so on.
(b)
Name of the cities in Oregon.
Level of measurements: nominal
Because in case of nominal level of measurements the variables are classified using names, labels, alpha numeric data, and so on.
(c)
The years in which economists have deemed the U.S. to be in recession.
Level of measurements: interval
Because in case of interval level of measurement, the data is not only classified and ordered, but it also specifies that the distances between each interval on the scale that are equal throughout the scale from low to high interval.
(d)
The category which best describes how frequently a person eats chocolate: Frequently, Occasionally, Seldom, Never.

A rectangle is 1 inch longer than it is wide. Its diagonal is 5 inches. What's the width of the rectangle?
Answer:
Step-by-step explanation:
Let x be the length and y be the width
The length is 1 inch longer than the width
So : x-1 =y
●●●●●●●●●●●●●●●●●●
The diagonal is 5 inches
The diagonal, width and length are forming a right triangle where the diagonal is the hypotenus
The Pythagorian theorem:
x^2 + y^2 = 5^2
●●●●●●●●●●●●●●●●●●●●●●●
Let's calculate y the width
The system is :
x-1 = y => x =y+1
x^2 + y^2 = 25
Replace x in the second equation with y+1 :
(y+1)^2 + y^2 = 25
y^2 + 2y + 1 + y^2 = 25
2y^2 + 2y +1 = 25
2y^2 + 2y -24 = 0
This is a quadratic equation so we will use the discriminant
●●●●●●●●●●●●●●●●●●●●●●
the discriminat is b^2-4ac
● b =2
● a = 2
● c = -24
b^2 -4ac = 4-4*2(-24) =196 > 0
Since the dicriminant is positive this equation has two solutions y and y'
y = (-2-14)/4 = -16/4 = -4
y '= (-2+14)/4 = 12/4 = 3
The first solution is negative
A distance is always positive so the first solution can't be the width
Then the width is 3

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.

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.
