In the adjoining figure , AB = 6 , BC = 8 , [tex] \angle[/tex] ABC = 90° , BD ⊥ AC and [tex] \angle[/tex] ABD = [tex] \theta[/tex] , find the value of sin [tex] \theta[/tex].
Here we are given with a triangle with smaller triangles formed due to the altitude on AC. Given:
AB = 6BC = 8<ABC = 90°BD ⊥ AC<ABD = [tex] \theta[/tex]We have to find the value for sin [tex] \theta[/tex]
So, Let's start solving....
In ∆ADB and ∆ABC,
<A = <A (common)<ABC = <ADB (90°)So, ∆ADB ~ ∆ABC (By AA similarity)
The corresponding sides will be:
[tex] \sf{ \dfrac{AD}{AB} = \dfrac{AB}{AC} }[/tex]
We know the value of AB and to find AC, we can use Pythagoras theoram that is:
AC = √6² + 8²
AC = 10
Coming back to the relation,
[tex] \sf{ \dfrac{AD}{6} = \dfrac{6}{10} }[/tex]
[tex] \sf{AD = \dfrac{6 \times 6}{10} = 3.6}[/tex]
In ∆ADB, we have to find sin [tex] \theta[/tex] which is given by perpendicular/base:
[tex] \sf{\sin( \theta) = \dfrac{AD}{AB} }[/tex]
Plugging the values of AD and AB,
[tex] \sf{\sin( \theta) = \dfrac{3.6}{6} }[/tex]
Simplifying,
[tex] \sf{ \sin( \theta) = \dfrac{3}{5} = \boxed{ \red{0.6}}}[/tex]
And this is our final answer.....

Prove that in any triangle the length of a side is less than the half of the perimeter in statement reason format.
Answer:
Proved
Step-by-step explanation:
I am going to pose c as the largest side in a random triangle
If so then remember that, by the triangle inequality, a + b > c. Let's start from there...
Statement: | Reasoning:
1. a + b > c 1. Triangle Inequality
2. a + b + c > c + c (adding c on both sides), 2. Algebra + Def. Of Perimeter
a + b + c > 2c (simplified)
Perimeter > 2c (definition of perimeter)
c < 1/2 * Perimeter
The prove of statement ''in any triangle the length of a side is less than the half of the perimeter'' is shown.
What is Perimeter?
The sum of all sides of a quadrilateral is called a perimeter.
Given that;
The statement is,
''In any triangle the length of a side is less than the half of the perimeter''.
Now,
Let sides of triangles are a, b and c.
The triangle inequality is;
a + b > c
Add both side by c;
a + b + c > c + c
a + b + c > 2c .... (i)
Since, Perimeter of a triangle with sides a, b and c is;
Perimeter (P) = a + b + c
Substitute value of perimeter in equation (i), we get;
a + b + c > 2c
P > 2c
c < P/2
Thus, In any triangle the length of a side is less than the half of the perimeter.

1. Which is the smallest set of real numbers that contains the value below? -18 /6
A. Irrational Numbers
B. Rational Numbers
C. Natural Numbers
D. Integers
Answer:
Integers
Step-by-step explanation:
The correct option to choose is the integers option. Integers are simply whole numbers.
Thus-18/6 = -3
The term -3 is a whole number
So the term to choose is the integers option
The smallest set of real numbers that contains the value -18 /6 is an integer.
The smallest set of the real number that contains the value -18/6 can be determined after we have simplified the expression -18/6.
To simply the given expression, we will divide both the numerator and the denominator by 6, by doing so, we have:
= -3
Now, the smallest set of the real number is = -3 which is an integer
This is because an integer is a whole number that is not a fraction and can be negative or positive.
The reason why it is not a natural number is because of the negative sign, since we know that natural numbers are numbers with positive signs only.

. A bakery sells 1,230 cakes during a holiday season. One-third of them are caramel cakes, one-half are chocolate cakes, and the remaining are banana cakes. What is the total amount earned by the bakery by selling the cakes during the holiday season?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Cakes = 1230[/tex]
[tex]Caramel = \frac{1}{3}[/tex]
[tex]Chocolate = \frac{1}{2}[/tex]
[tex]Banana = ??[/tex]
Required
Determine the total amount earned
The given parameters can't be used to determine the total amount earned.
However, we'll make some assumptions
First, we need to solve for the amount of each cake sold
[tex]Caramel = \frac{1}{3}[/tex]
[tex]Caramel = \frac{1}{3} * 1230[/tex]
[tex]Caramel = 410[/tex]
[tex]Chocolate = \frac{1}{2}[/tex]
[tex]Chocolate = \frac{1}{2} * 1230[/tex]
[tex]Chocolate = 615[/tex]
[tex]Banana = 1230 - 410 - 615[/tex]
[tex]Banana = 205[/tex]
Assume that:
Each caramel were sold at x
Each chocolate were sold at y
Each banana were sold at z
[tex]Total\ Amount = 410 * x + 615 * y + 205 * z[/tex]
[tex]Total\ Amount = 410x + 615y + 205z[/tex]

All real numbers except n Pi, where n is an integer. Option C is correct.
What is the difference between domain and range?The domain denotes all potential x values, while the range denotes all possible y values.
Given function;
y = csc(x)
Anything that is real, excluding n Pi, where n is an integer.

The perimeter of a rectangle is 64 feet. The length of the rectangle is 3 times the width of the rectangle. If w represents the width of the rectangle, the equation that represents the perimeter is 2 (3 w) + 2 w = 64. Which shows the first step that should be taken to verify that the width of the rectangle is 8? A regular hexagon and a rectangle have the same perimeter, P. A side of the hexagon is 4 less than the length, l, of the rectangle. The width of the rectangle, w, is 2 less than the length of the rectangle. What is the perimeter of the hexagon?
Step-by-step explanation:
given the perimeter is
64ft
the length l= 3w
we know that the perimeter of a rectangle is given as
P=2l+2W
but L=3w
64=2(3w)+2w
64=6w+2w
64=8w
divide both sides by 8 we have
w=64/8
w=8ft
also
let the lenght of the rectangle be l
side of hexagon=l-4
perimeter of hexagon
P=5(l-4)
P=5l-20
width of rectangle w=l-2
perimeter of rectangle= 2l+2w
but w=l-2
5l-20= 2l+2(l-2)
5l-20=2l+2l-4
5l-20=4l-4
5l-4l=-4+20
l=16ft
perimeter of hexagon
P=5(l-4)
put l=16
perimeter of hexagon
P=5(16-4)
p=5(12)
P=60ft
Answer: 2(3(8))+(2+8)=64 or c
Step-by-step explanation:
You have to replace w with 8 meaning 8 is now the width, therefore, c is the correct answer.

(a) We need to find the maximum price per share of the stock. For maximum value, put :
