Amount in compound interest = p(1 + r/t)^nt where p is the initial
deposit, r = rate, t = number of compunding in a period and n = period.
Here,
Amount after 4 years = 500(1 + (2/100)/3)^(4 x 3) = 500(1 +
0.02/3)^12 = 500(1 + 0.0067)^12 = 500(1.0067)^12 = 500(1.083000) =
$541.50
Answer:
n = -31.5
Step-by-step explanation:
let 'n' = the number
n/-1.5 = 21
to solve for 'n', multiply each side by -1.5 to get:
n = -31.5
Correct option is D) -0.6.
<u>Step-by-step explanation:</u>
We have
. Also, we know that
. Let's find out value of
using above formula:

⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
But we know that cos
is negative in third quadrant , Therefore
.
Hence, correct option is D) -0.6.
To solve this, we need to rearrange to get like terms by each other. Remember to distribute the negative.
