Dan bought a truck for $29,800. The value of the truck depreciated at a constant rate per year. The table shows the value of the

leonid [27]

Answer:

A) f(t) = 29,800(0.89)^t

Step-by-step explanation:The truck value decreases by 11% each year.

The present value of the truck was $29,800.

29,800 x 0.11 = 3,728 dollars lost from value.

29,800 - 3,728 = 26,522, the value of the truck after one year.

26,522 x 0.11 = 2,917.42 cash lost from value.

26,522 - 3,728 = 23,604.58, the value of the truck after two years.

Therefore, the answer is A) f(t) = 29,800(0.89)^t.

When producing hydrogen iodide, the energy of the reactants is 581 kJ/mol, and the energy of the products is 590 kJ/mol. The equ

dimaraw [331]

The energy of the reaction is 9 kJ/mol and the reaction is endothermic.

<h3>What is the total energy of the reaction?</h3>

We know that in a reaction, there could be loss or gain of energy. If there is a loss of energy in a reaction, it means that the reaction is exothermic and heat is given out. If heat is gained in the reaction, it means that the reaction is endothermic and heat is absorbed.

Given that;

Energy of the products = 590 kJ/mol

Energy of the reactants = 581 kJ/mol

Using;

Energy of products - Energy of reactants

= 590 kJ/mol - 581 kJ/mol

= 9 kJ/mol
