When dividing exponents with the same base, what operation do we use
mario62 [17]

Answer:

To divide exponents (or powers) with the same base, subtract the exponents. Division is the opposite of multiplication, so it makes sense that because you add exponents when multiplying numbers with the same base, you subtract the exponents when dividing numbers with the same base.Quotient Rule: , this says that to divide two exponents with the same base, you keep the base and subtract the powers. This is similar to reducing fractions; when you subtract the powers put the answer in the numerator or denominator depending on where the higher power was located.

Use the formula for continuous compounding to compute the balance in the account after 1,5, and 20 years. Also, find the APY for
densk [106]

Answer:

After 1 year: $7,256.59

After 5 years: $8,380.52

After 20 years: $14,381.03

APY = 3.66%

Step-by-step explanation:

If you deposit $7000 with an interest of 3.6%, after 1 year using continuous compounding, you will have

7000e^{0.036}=7,256.59

After 5 years you will have

7000e^{5(0.036)}=8,380.52

After 20 years

7000e^{20(0.036)}=14,381.03

To find the APY for the account, we have to compute the interest earned in one year.

We can do it by cross multiplying or by finding a number x such that

7000(1+\frac{x}{100})=7,256.59

Operating on this equation we obtain

x = 0.0366 or 3.66%

Domain of y=∛-3x+5
Feliz [49]
Since you can take the cube root of any number (even a negative), no number is not included in the domain. The domain is all really numbers. the whole negative infinity to infinity is saying that in a different way. It says, the domain goes from negative infinity to infinity, so theres is no number that would not work.
