What are growth and decay formulas

charle [14.2K]

Answer:

Exponential Growth: y = a(1 + r)x

Exponential Decay: y = a(1 - r)x

Explanation:

Remember that the original exponential formula was y = abx.

You will notice that in these new growth and decay functions,

the b value (growth factor) has been replaced either by (1 + r) or by (1 - r).

The growth "rate" (r) is determined as b = 1 + r.

The decay "rate" (r) is determined as b = 1 - r

If you wanted to combine equal numbers of Na and Cl atoms in a flask, how much Cl would you have to add if you added 23g of NA?

Gwar [14]

Answer: The mass of chlorine atom required to combine is 35.5 grams.

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

For sodium:

Given mass of sodium = 23 g

Molar mass of sodium = 23 g/mol

Putting values in equation 1, we get:

$\text{Moles of sodium}=\frac{23g}{23g/mol}=1mol$

According to mole concept:

1 mole of an atom contains $6.022\times 10^{23}$ number of particles

So, 1 mole of sodium will contain = $(1\times 6.022\times 10^{23})=6.022\times 10^{23}$ number of atoms

Number of atoms of chlorine = Number of atoms of sodium = $6.022\times 10^{23}$ = 1 mole

Now, calculating the mass of chlorine required by using equation 1:

Moles of chlorine = 1 mole

Molar mass of chlorine = 35.5 g/mol

Putting values in equation 1, we get:

$1mol=\frac{\text{Mass of chlorine}}{35.5g/mol}\\\\\text{Mass of chlorine}=(1mol\times 35.5g/mol)=35.5g$

Hence, the mass of chlorine atom required to combine is 35.5 grams.

A new golf course is built next to a river. Over the past several months, the nitrate levels of the water in the river have been

elena-14-01-66 [18.8K]

Answer:

The answer is "runoff from fertilizer".

Explanation:

The fertilizer is any natural or synthetic material, which is applied with soil or tissue of plant species and provides one or more plant foods, which are necessary for plant growth.

Due to the high durability and excessive irrigation use, nitrate fertilizers, which provide high solubility, as well as the nitrate ion throughout the finishes the product and readily drained away, that's why the given choice is correct.

glucose is molecule that can move acoss the cell membrane. I f the concentration of glucose is higher than the outside cell what

blondinia [14]

Answer: If the concentration of glucose inside the cell is higher than the one outside the cell, glucose molecules will move from inside the cell to the outside of the cell in a process of diffusion.

Explanation: Diffusion is the movement of solute molecules from a region of higher concentration to a region of lower concentration. The inside of the cell has higher glucose concentration i.e., has higher quantity of glucose molecules than outside of the cell which has a lower glucose concentration, therefore glucose molecules will move from inside the cell to outside the cell. The purpose of this is to create a balance in glucose concentrations in the two environments.
