base area of prism = (Volume of rectangular prism) / height

What is the volume of the rectangular prism?

The extent of a square prism is described as the gap occupied inside a square prism. A square prism is a polyhedron that has pairs of congruent and parallel bases. It has 6 faces (all are square),12 sides, and eight vertices. As the square prism is a 3-dimensional shape (3-d shape), the unit this is used to specific the extent of the square prism is \(cm^{3}\)and so on. In mathematics, any polyhedron, having all such traits may be known as a Cuboid.

As we know,

Volume of rectangular prism = base area of prism × height

Using this formula , we can find the base area of rectangular prism as

base area of prism = (Volume of rectangular prism) / height

To calculate the concentrations of all species present in a 0.72 M NH3 solution (Kb=1.8×10−5), we can use the principles of the equilibrium expression for the dissociation of NH3 in water.

NH3 (ammonia) is a weak base that reacts with water to form NH4+ (ammonium) and OH- (hydroxide) ions. The equilibrium expression for this reaction can be written as:

NH3 + H2O ⇌ NH4+ + OH-

Since the initial concentration of NH3 is 0.72 M, we can assume that x mol/L of NH3 will dissociate to form x mol/L of NH4+ and OH-. Therefore, the concentrations of NH4+ and OH- will also be x mol/L.

To calculate the value of x, we can use the Kb expression, which relates the equilibrium constant to the concentrations of the species. In this case, Kb = [NH4+][OH-]/[NH3]. Substituting the known values, we have:

1.8×10−5 = x * x / (0.72 - x)

Solving this equation will give us the value of x, which represents the concentration of NH4+ and OH-. Finally, we can express the concentrations of NH3, NH4+, and OH- using two significant figures, separated by commas, based on the calculated value of x.

The equation of hyperbola :  \(\frac{y^{2} }{49 } - \frac{x^{2} }{32 }\)

Step-by-step explanation:

Given - This hyperbola is centered at the origin.

Foci: (0,-9) and (0,9) Vertices: (0,-7) and (0,7)​

To find - Find its equation.

Solution -

We know  that,

Equation of Hyperbola is represented by

\(\frac{y^{2} }{a^{2} } - \frac{x^{2} }{b^{2} }\)

Now,

Given that,

Foci : F(0, -9) and F'(0, 9)

So,

c = 9

And

Vertices : A(0,-7) and A'(0,7)​

So,

a = 7

Also, we know that,

c² = a² + b²

⇒b² = c² - a²

⇒b² = 9² - 7²

⇒b² = 81 - 49

⇒b² = 32

So,

The equation of hyperbola becomes

\(\frac{y^{2} }{49 } - \frac{x^{2} }{32 }\)

The frequency of heterozygous individuals in the population of piranhas can be calculated using the Hardy-Weinberg equilibrium equation. The dominant allele 'A' occurs with a frequency of 0.8, Assuming that the recessive allele 'a' occurs with a frequency of 0.2 .

According to the Hardy-Weinberg equilibrium, the frequency of heterozygous individuals (Aa) can be determined using the formula 2 xp xq, where p represents the frequency of the dominant allele and q represents the frequency of the recessive allele. In this case, p = 0.8 and q = 0.2. By substituting the values into the equation, we can calculate the frequency of heterozygous individuals as follows: Frequency of heterozygous individuals = 2 x 0.8 x0.2 = 0.32. Therefore, the frequency of heterozygous individuals in the population of piranhas is 0.32, or 32% (rounded to two decimal places). This means that approximately 32% of the individuals in the population carry both the dominant and recessive alleles, while the remaining individuals are either homozygous dominant (AA) or homozygous recessive (aa).

The circumference of the well is 3.93 ft.

Given, Emma is making a scale drawing of her farm using the scale 1 cm=2.5 ft

Diameter of the well she drew = 0.5 cm

We need to convert the diameter of the well from centimeters to feet, using the given scale.

i.e. 0.5cm = 2.5/2 = 1.25 ft

We know the radius is half of the diameter.

So, r = 1.25/2 = 0.625

We know that the formula for the circumference of a circle is C = 2πr

C = 2*3.14*0.625

= 3.93 ft

Hence, the circumference of the well is 3.93 ft.

Step-by-step explanation:

In order to find the entire area of the rectangle, you have to first find the values of each quadrant, then you add the values together to find the answer. The top left quadrant is x times x, which is \(x^{2}\). The top right value is x times 7, which is 7x. the bottom left value is x times 5, which is 5x, and the bottom right value is 7 times 5, which is 35. Put all the answers together and you get \(x^2+5x+7x+35\), which simplifies to \(x^{2}+12x+35\)
