At the beginning of year 1, sam invests 700 at an annual compound interest rate of 5%, he makes no deposits to or withdrawals from the account. which explicit formula can be used to find the account's balance at the beginning of year 4? what is the balance? a) 805. b) 825.42 c) 850.85 d) 810.34

(d) 810.34

Step-by-step explanation:

The explicit formula used for calculating the account's balance is given by:

A= P(1+R)^T

where: A= Amount (account's balance)

P= Principal  (700)

R= Rate (5%)

T= Time   (3 years) [since, the balance is calculated in the beginning of the  forth year]

A= P(1+R)^T

A = 700(1+0.05)^3

  = 700(1.05)^3

  = 700*1.157

  = 810.34

step-by-step explanation:

use context clues to figure out the meaning of the bolded word:  

the sage gardener knew when she had to water her plants.  

question 8 options:

mint plant

wise

happy

lazy

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
