Find the balance in the account. 4. $3,900 principal earning 2%, compounded annually, after 3 years

$4138.7

Step-by-step explanation:

P= $3,900

R= 2%

T or n= 3 years

compounded anually (yearly) so:

A= P(1+)

A= 3900(1+)

A= $4138.7

the answer is 37

step-by-step explanation:

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
