Isosceles triangle ΔABD
The triangle ΔABD that have side AB congruent to side BD is an isosceles triangle by definition of an isosceles triangle.
The base angles of an isosceles triangle that are angles opposite congruent sides in a triangle are also congruent.
Definition of congruency
A geometric figure is congruent to another figure if their measurements are the same.
Exterior angle theorem
The exterior angle of a triangle theorem states that the exterior angle of a triangle is equal to the sum of the two interior opposite angles.
Substitution property
The substitution property of equality states that if a quantity a is equal to another quantity b then a can be substituted by b in expressions and equations without changing their value.
Subtraction property
The subtraction property of equality states that if the same quantity is subtracted from both sides of an equation, then the new amount obtained are also equal

Your team has contracted to design and build a 500 ft, square-based, open-top, rectangular steal holding tank for a paper company. The tank is to be made by welding thin stainless steel plates together along their edges. As the production engineer, your job is to find dimensions for the base and height that will make the tank weight as little as possible.
For dimensions of x =10 and y=5 for the base and height that will make the tank weight as little as possible.
Here we are given the information of a square-based, open-top, rectangular steel holding tank, so here the tank is in the shape of a cuboid and we know the formula for :
volume = x*y*z, as here it is a square base, so the volume will be
volume = x²*y, where x and y are the dimension of the base and height
So for the given reason,
=>x²*y = 500
=> y = 500/x²
Again, the surface area formula will be
S=x²+4xy, substituting the value of y in this question
=>S=x²+4x(500/x²)
=>S=x²+2000/x
Differentiating the above formula with respect to x, we get
=>2x-2000/x²=0
=>2x³= 2000
=>x³= 1000
=>x =10
so the substituting the x values of x in the equation y , we get
y = 500/x²
=>y = 5
so the dimensions are x= 10 and y=5

What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
the curved red line represents g(x) and the straight blue line represents f(x) .
The important thing here is that the equality of functions f(x)=g(x) is represented as a common function between their curves. So, we just need to find such a common point for both.
f(x) has points (0, 4) and (2, 0).
g(x) has points (0,4) and (2,0).
Notice that both functions have the same y-value for x=0 and x=2, that means f(0)=g(0) and f(2)=g(2)

Write the constraints to represent this real-world problem, where x is the temperature and y is the number of people on your trip.
The correct answer is (C) since the limitations to depict this real-world problem in inequality are 75 < x < 110 and 0 < y ≤ 50.
What is inequality?The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity.
This shows that the left half, 5x 4, is bigger than the right part, 2x + 3.
So, our senior trip will be a group excursion to a beach.
Only when the temperature is between 75 and 110 degrees does the resort permit swimming.
On your excursion, there is space for 50 people.
Let y represent the number of travelers and x represent the temperature.
The temperature ranges from 75 to 110 degrees:
75 < x < 110
On your excursion, there is space for 50 persons:
0 < y ≤ 50

Permutation:
In probability, permutation refers the arrangement of objects in a definite order.
Given,
Alice and Bob are playing a game in which there are several rounds and each round can be a win, a loss, or a draw for Alice.
Here we need to find the number of ways can Alice win or draw exactly three times, if they play 6 rounds.
While we looking into the given question, we know that,
Total number of games = 6
Possible values = 3 ( win, loss, or draw)
Here we need to find the probability of winning 3 times, it can be calculated by using the permutation as,
=> 6! / (6 - 3)!
=> 6! / 3!
=> 120
Similarly, the the probability of draw 3 times, it can be calculated by using the permutation as,

a) The expected return for stocks a and b is 13.56% and 20.02% respectively.
b) The standard deviation for stocks a and b are 8.32% and 32.60%.
a) Expected return = Probability of recession × Return during recession + Probability of normal × Return during normal + Probability of boom × Return during boom
Expected return for stock A = 0.21 × 0.04 + 0.61 × 0.12 + 0.18 × 0.30
The expected return for stock A = 0.1356
The expected return for stock A = 13.56%
Expected return for stock B = 0.21 × (-0.41) + 0.61 × 0.31 + 0.18 × 0.54
The expected return for stock B = 0.2002
The expected return for stock B = 20.02%
b) Standard deviation of stock = √{Probability(Recession) × (Rate during recession - expected rate )² + Probability(Normal)(Rate during normal - expected return)² + Probability(Boom) × (Rate in boom - Expected return)²}
Standard deviation of stock A = √[(0.21 × (0.04-0.1356)² + 0.61 × (0.12 - 0.1356)² + 0.18 × (0.30-0.1356)²)]
The standard deviation of stock A = 0.0832
The standard deviation of stock A = 8.32
Standard deviation of stock B = √(0.21 × (-0.41-0.2002)² + 0.61(0.31 - 0.2002)² + 0.18 × (0.54-0.2002)²)]

The intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing is x>-b/2a and x<-b/2a
Given that,
We have to find the intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing.
We know that,
Take the function equation,
f(x)=ax² + bx + c
The derivative of the function of x is
f'(x)=ax+b
So, f(x) is increasing when f'(x) > 0
f(x) is decreasing when f'(x) < 0
Then we can say
f'(x) > 0 , when b > 0 and a < 0
2ax + b < 0
2ax < - b
x<-b/2a
Now,
f'(x) < 0 , when b < 0 and a > 0
2ax + b > 0
2ax > - b
x>-b/2a
Therefore, the intervals on which the function f(x) = ax² + bx + c (where "a" doesn't = 0) is increasing and decreasing is x>-b/2a and x<-b/2a.
