The congruence theorem that will prove △BDA and △DBC is A. Hypotenuse-leg (HL) congruence.

Determining the right congruence theorem that will prove △BDA and △DBC after being provided a schematic of two right triangles.

Since we are aware that the hypotenuse-leg theorem stipulates that if the hypotenuse and one of the right triangles' legs are congruent with their equivalent hypotenuses in other right triangles, the triangles are said to be congruent.

We can see from our diagram that hypotenuse(AB) of △BDA equals to hypotenuse (CD) of △DBC.  

We can see that triangles BDA and DBC share a common side DB.

Using Pythagorean theorem we will get

CD² = DB²+BC²

AB = DB²+AD²

given that CD=AB, Upon using this information we will get,

DB²+BC² = DB²+AD²

subtracting DB² from both sides of our equation we will get,

BC² = AD²

Cutting squares on both sides

BC = AD

Hence, by HL congruence △BDA ≅ △DBC.

Note that the full question is:

Which congruence theorem can be used to prove △BDA ≅ △DBC?

A. HL

A parallel equation is an equation that is composed of two or more equations that are related to each other.

An example of a parallel equation is:   x + y = 4  And x - y = 2  In this equation, x and y are related to each other by an addition and a subtraction. The two equations have the same value on each side, 4 and 2, so they are parallel equations. To solve this equation, we need to find the value of x and y. To do this, we add the two equations together, giving us:  2x = 6. Therefore, x = 3. To find y, we can plug 3 in for x in either equation and solve for y, giving us y = 1. Therefore, the solution for this parallel equation is x = 3 and y = 1.

True, When the demand is greater than the capacity, impossible situations can arise.

Demand is outlined as the quantity of a good that buyers are willing and able to purchase at a specific price. This is an if...then statement, thus if the price is $1,000, the quantity demanded is 60, and so on. Therefore, it is a function with the form y = f(x), where x now represents price and y represents quantity.

A linear demand equation is defined as Q = a - bP in standard form. In other words, pricing influences the quantity demanded. The price equation, often known as the inverse demand equation or price equation, treats the price as a function f of the amount demanded: P = f. (Q). Simply solve for P from the demand equation to obtain the inverse demand equation.

So, the answer is true that when the demand is greater than the capacity, impossible situations can arise.

Check whether a polynomial function is an odd-degree or even-degree function, as well as whether the leading coefficient is positive or negative, before attempting to determine its end behavior.

Given,

The polynomial end behavior;-

The behavior of the function graph at the "ends" of the x-axis is known as the end behavior of a function, or f. In other words, if we look at the right end of the x-axis (as x approaches +) and the left end of the x-axis (as x approaches ), the end behavior of a function represents the trend of the graph.

Here,

Look at the polynomial function's leading term to identify its end behavior. The leading term will dominate the graph since it has the largest power and will thus increase much more quickly than the other terms as x gets very large or very small.

That is,

Check the function's odd- or even-degree status and the leading coefficient's positive or negative value before attempting to forecast the polynomial function's end behavior.

To find the scale factor of dilation we need to know the coordinated and centre point of dilation

The scale factor of a dilation is a number that represents the relationship between the lengths of objects before and after the dilation. It is equal to the ratio of the lengths of corresponding sides after and before the dilation.

To find the scale factor of a dilation, it is required to know the coordinates of the two points that the dilation acts on. The scale factor is then given by the ratio of the distances between the two points after and before the dilation. We locate the centre of the dilatation, and then we measure the distances between this centre and various points on the preimage and the final image. Then the scale factor is determined by the ratio of these distances.

The cost of constructing the box will be = $81.77

Since the question gives us information about the rectangle,

so the area of the rectangle is shown by,

Area = 2 x (length + width)

So we have the area as,

Area = 2(lh + wh) +lw

(since the area per square meter is also given so we added l x w)

Since the cost of the base is = $5 per square meter and the cost of the sides is = $3 per square meter, so area in terms of the cost function,

⇒ C = 3 x 2(lh + wh) + 5 x l x w

⇒ C = 6(lh + wh) +5lw ---------equation 1

According to the question, the length of the rectangular container is twice that of the width of the container,

⇒ l = 2w

Substituting the new value of l in equation 1,

⇒ C = 6(2wh + wh) + 10 [tex]w^{2}[/tex]

⇒ C = 18wh + 10 [tex]w^{2}[/tex] ---------- equation 2

To calculate the volume of the rectangle,

V = length x width x height ( lwh )

substituting v = 10 and 2w = l,

2[tex]w^{2}[/tex]h = 10

h = [tex]\frac{5}{w^{2} }[/tex]

Substitute the value of h in equation 2,

⇒ C = 18w x [tex]\frac{5}{w^{2} }[/tex] + 10[tex]w^{2}[/tex]

⇒ C = [tex]\frac{90}{w}[/tex] + 10[tex]w^{2}[/tex] --------- equation 3

Differentiating the above equation we get,

⇒ C* = - [tex]\frac{90}{w^{2} }[/tex] + 20w

⇒ 20w = [tex]\frac{90}{w^{2} }[/tex]

Multiply both sides by [tex]w^{3}[/tex]

⇒ [tex]20w^{3}[/tex] = 90

⇒ [tex]w^{3}[/tex] = 4.5

w = 1.65

Put the value of w in equation 3,

⇒ C = [tex]\frac{90}{1.65}[/tex] + 10 x [tex]1.65^{2}[/tex]

The term splitting is one of the methods used in factoring the quadratic expression.

We know that the general form of quadratic equation is ax² + bx + c = 0

The term splitting is one of the methods used in factoring the quadratic equation. When we can not square the first and the last term of the quadratic expression then we can use the method of splitting of the middle term. In this method we have to rewrite the middle term of the quadratic expression as the sum or difference of the two terms (the first and the last term).

For example, to factor a quadratic expression 4x² + 8x - 5

first find the product of the first and last term: 4 x (-5) = -20

Now, find the factors of -20 in such way that addition or subtraction of that factors is the middle term (8x) (Splitting of middle term):

10 x (-2) = -20 and 10 - 2 = 8

Now we write the quadratic expression using the sum of the two new factors, including the proper signs.  

4x² + 10x - 2x - 5

Now,factor each pair by finding common factors.  

2x( 2x + 5) - 1(2x + 5)

Now, factor out the common binomials.  

(2x - 1) ( 2x + 5)

Therefore, the quadratic factorization uses splitting of middle term wtere the middle term of quadratic expresseion is splitted in to two factors.

The 100 feet per second rate at which rocket is rising vertically upwards and the 50 feet distance of the observation position from the launch, indicates;

A) The height of the rocket after exactly 2 seconds is 200 feet

B) The rate of the angular motion at which to scan upwards to keep track of the rocket is 2/17 radians per second

Angular motion is a circular motion of an object about a fixed axis, described in radians per second.

The rate at which the rocket is rising up in the air = 100 feet per second

The horizontal distance from the point of launch to the observer = 50 feet

The time at which the height of the rocket is required = 2 seconds

A) The height of the rocket after 2 seconds, h = 2 s × 100 ft/s = 200 ft

B) The angle of elevation of the line of sight to the rocket = θ

tan(θ) = h/50

sec²(θ)·(dθ/dt) = (1/50)·(dh/dt)

(dθ/dt) = (1/50) × (dh/dt)/sec²(θ)  = (1/50)×(dh/dt)×(cos²(θ))

At time, t = 2 seconds, the height of the rocket = 200 feet

Therefore;

tan(θ) = 200/50 = 4

θ = arctan(4)

dh/dt = The vertical velocity of the rocket = 100 ft/s

The correct option is option C. $110

An out-of-pocket expense is an health expense incurred by an insured person, for which the insured person is not reimbursed.

The monthly premium for the family's health insurance plan = $55

The coverage offered by the health insurance for the first $600 = 90%

The coverage for prescription above $600 = 80%

The expected number of prescriptions by the family per month = 6

The total cost of the family's monthly prescription = $850

Therefore, the out-of-pocket expense by the family for one month are;

Out-of-pocket prescription for the first $600 = $600 - 90% × $600 = $60

Amount of prescription over $600 = $850 - $600 = $250
