Answer : The correct option is, Yes, the equation is balanced. There are the same number of Hydrogen (H) and Oxygen (O) atoms on both sides of the equation.

Step-by-step explanation :

Law of conservation of matter : It states that matter can neither be created nor be destroyed but it can only be transformed from one form to another form.

The balanced chemical reaction always follow the law of conservation of mass.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The given chemical reaction is,

$2H_2+O_2\rightarrow 2H_2O$

This reaction is a balanced chemical reaction in which number of atoms of hydrogen and oxygen are equal on the both side of the reaction. So, this reaction obey the law of conservation of matter.

Find the range for the function: y=x-7 {-3,0,2,5}

trasher [3.6K]

Answer:

Range is : { -10, -7, -5, -2 }

Step-by-step explanation:

Given:

The function is given as:

$y=x-7$

The domain of the function = { -3, 0, 2, 5 }

A function's input is called its domain and a function's output is called its range.

The range depends on the domain values. So, the values of 'y' are the values of range and the values of 'x' are the values of domain.

Here, the domain is given as:

Domain = { -3, 0, 2, 5 }

We need to find the values of 'y' for each value of 'x' taken from the domain set.

Plug in $x=-3$ . This gives,

$y=-3-7=-10$

Plug in $x=0$ . This gives,

$y=0-7=-7$

Plug in $x=2$ . This gives,

$y=2-7=-5$

Plug in $x=-5$ . This gives,

$y=5-7=-2$

Therefore, the set of all values of 'y' is the range.

Range is equal to { -10, -7, -5, -2 }.

Ann and Tom want to establish a fund for their grandson's college education. What lump sum must they deposit at an 8.2% annual

GaryK [48]

Compound interest formula = a=P(1+r/n)^nt

P= lump sum to deposit (solving for)

A= amount accumulated over the entire time (20000)

n= number of times interest is compounded annually (1)

r= rate of interest (0.82)

T= total number of years (15)

20000=P(1+0.082/1)^1*15

20000=P(1.082)^15
20000=P(3.26143638)
20000/3.26143638=P
P=$6132.2674
