Triangle GED and triangle DEH are similar triangles with a common side length DE

The value of x is 24

<h3>How to calculate the value of x</h3>

To calculate x, we make use of the following equivalent ratio

GD : DH = EG : EH

Substitute known values

x + 4 : 35= 44.8 : 56

Express the ratio as fraction

\frac{x + 4}{35}= \frac{44.8}{ 56}

Evaluate the quotient

\frac{x + 4}{35}= 0.8

Multiply both sides by 35

x + 4= 28

Subtract 4 from both sides

x= 24

Hence, the value of x is 24

Given the function f(x) = 3(x – 2)2 + 4 with a restricted domain of x ≥ 2, which of the following represents f–1(x)?.
Debora [2.8K]

The inverse of the function is f^{-1}x= \sqrt{\frac{x-4}{3} } + 2

<h3 /><h3>Domain and Range of functions</h3>

Given the function

f(x) = 3(x - 2)^2 + 4

To get the inverse, you will follow the same step as shown:

Rewrite the equation to have:

y= 3(x - 2)^2 + 4

Replace x with y

x = 3(y - 2)^2 + 4

<h3>Make y the subject of the formula</h3>

x = 3(y - 2)^2 + 4\\x-4=3(y - 2)^2\\\frac{x-4}{3} = (y-2)^2\\ y-2=\sqrt{\frac{x-4}{3} } \\y = \sqrt{\frac{x-4}{3} } + 2

Hence the inverse of the function is f^{-1}x= \sqrt{\frac{x-4}{3} } + 2

What maximum amount of ammonia in kilograms can be synthesized from 5.22 kg of h2 and 31.5 kg of n2?
Fiesta28 [93]

Consider the unbalanced reaction,

H₂ + N₂   ===>   NH₃

Balance it to get

3 H₂ + N₂   ===>   2 NH₃

This tells you that for every 3 moles of H₂ and 1 mole of N₂ among the reactants, 2 moles of NH₃ are produced.

Look up the molar masses of each component element:

• H : 1.008 g/mol     ===>   H₂ : 2.016 g/mol

• N : 14.007 g/mol     ===>   N₂ : 28.014 g/mol

• NH₃ : 17.031 g/mol

Convert the given mass to moles for each reactant:

• H₂ :

(5.22 kg) × (1000 g/kg) × (1/2.016 mol/g) ≈ 2589.29 mol

• N₂ :

(31.5 kg) × (1000 g/kg) × (1/28.014 mol/g) ≈ 1124.44 mol

Now,

(2589.29 mol H₂) : (1124.44 mol N₂) ≈ (2.30 mol H₂) : (1 mol N₂)

so that the amount of N₂ consumed is

(2589.29 mol H₂) × (1 mol N₂) / (3 mol H₂) ≈ 863.095 mol N₂

leaving an excess of about 261.343 mol N₂, and producing

(2589.29 mol H₂) × (2 mol NH₃) / (3 mol H₂) ≈ 1726.19 mol NH₃

Convert this to a mass :

(1726.19 mol) × (17.031 g/mol) × (1/1000 kg/g) ≈ 29.3987 kg

So, up to 29.4 kg of NH₃ can be synthesized.
