An initial amount of $600 is invested in a compound savings account with an annual interest rate of 3.5%. 1. Define variables 2. Substitute into formula A = P(1+r)t 3. Evaluate What is the total amount after 2 years? What is the total amount after 4 years?

the amount after 2 years is $642.74

the amount after 4 years is $688.51

Step-by-step explanation:

the amount after 2 years is $642.74 and

the amount after 4 years is $688.51

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

∠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°
