Well invested $4000 in an account that earns 5.5% interest, compounded annually. the formula for compound interest is a(t)= p(1+i)^t how much did arlo have in the account after 4 years?

$4,955.30

Step-by-step explanation:

Using the formula A(t)= P(1+i)^t, we know:

A(t)-the total amount with interest earned

P-principal or initial deposit

i- interest rate in decimal form

t- time in years.

We substitute our values of P=4000, i=0.055 and t=4 to solve for A(t).

A(t)= 4000(1+0.055)^4

A(t)= 4000(1.055)^4

A(t)= 4000(1.23882)

A(t)=$4,955.30

the answer to this question is 3/19

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
