Answer:

d = square root of {(x2 - x1)^2 + (y2-y1)^2}

Explanation:

If you're referring to math-

the distance is equal to (the second x value minus the first x value)^2 plus (the second y value minus the first y value)^2

For example: this is my imaginary ordered pair, I want to find the distance between the points- (2,4) and (3,6)

So d= (3-2)^2 - (6-4)^2  all under a square root

3-2 is = to 1, and 1 squared is just 1.

6-4 is = to 2, and 2 squared is 4.

4+1 is = 5.

So your answer would be the square root of 5.

If your answer ended up as, for example, the square root of 16, you would go a step further and your answer, or distance would be 4, since 4^2 is 16

If a herd of deer lives in a forest where they eat the leaves of trees, then the amount of carbon in the trees and in the deer increases.

Matter cycling refers to the movement of matter (in this case carbon) from biotic and abiotic factors in an ecosystem.

The biotic components are living organisms, whereas abiotic components are the non-living part of the ecosystem.

The carbon is continuously cycling between living and non-living components in an ecosystem.

Based on the calculations, the molar solubility of AgCl in 0. 500 M of NH₃ is equal to 2.77 × 10⁻² M.

Given the following data:

First of al, we would write the properly balanced chemical equation for this chemical reaction:

                          [tex]AgCl(s)\rightleftharpoons Ag^{+} (aq)+ Cl^{-}(aq)[/tex]       Ksp = 1.8 × 10⁻¹⁰

                [tex]AgCl(s) + 2NH_3(aq)\rightleftharpoons Ag(NH_3)_2^{+}(aq)[/tex]   Kf = 1. 7 × 10⁷

K = Ksp × Kf

K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷

K = 3.06 × 10⁻³

Mathematically, the Ksp for the above chemical reaction is given by:

[tex]K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}[/tex]

x = 2.77 × 10⁻² M.

There are different ways to calculate math. What the student is to do in the above scenario are:

To Multiply the mass of the reactant by its molar mass to find the number of moles of the reactant. Use the chemical equation to find the number of moles of the product. Divide the number of moles of the product by its molar mass to find the mass of the product.

The law of conservation of mass is one that states that in form of chemical reaction, the total mass of reactants is known and regarded as  equal to the total mass of products.

The steps in mass calculations are mass  = moles × molar mass

Calculate moles = mass(Mg) ÷ molar mass, moles.

The approximate angle between the vectors named U and V with their magnitudes and dot product is gotten as; 91°

We are given;

Magnitude of Vector U; |U| = 34

Magnitude of vector V; |V| = 20

Dot Product of u and v; U.V = -10

Formula for angle between vectors is;

θ = cos⁻¹[(U.V)/|U| * |V|]

θ = cos⁻¹(-10/(34 * 20))

θ = cos⁻¹-0.0135

θ ≈ 91°
