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.
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

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.
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.

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).

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]
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
b² = 60² - 51²
b = 3√111
b = 31.607
Pythagorean Theorem is used to find any missing side of a right triangle if 2 other sides are present.

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 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.

a₃ = 2a₂ - 7 = 2(3) - 7 = 6 - 7 = - 1

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°.
