You need a compound interest formula solved for principal:
Principal = Total ÷ (1 + Rate)<span> ^ years
</span><span>
Principal = 40,000,/ (1.056) ^ 4
</span><span><span><span>Principal = 40,000 / 1.2435282985
</span>
</span>
</span>
Principal =
<span>
<span>
<span>
32,166.54
</span>
</span>
</span>
So, 32,166.54 deposited for 4 years at 5.6% interest (compounded annually) produces $40,000.

To find c you use cosine or adjacent/hypotenuse. To set up your equation it’ll look like h=16/cos(21). h=hypotenuse which is what your solving for. You should get 17.1383199. I’m not sure what your supposed round to so I gave the full answer.
The answer is
<span>x+1</span>, <span>x+2</span>, <span>x+3</span>, <span>x+4</span> and <span>x+5</span>.
The sum of these six integers is 393 so we can write:
<span>x+x+1+x+2+x+3+x+4+x+5=393</span>
<span>6x+1+2+3+4+5=393</span>
<span>6x+15=393</span>
<span>6x+15−15=393−15</span>
<span>6x+0=378</span>
<span><span><span>6x</span>6</span>=<span>3786</span></span>
<span>x=63</span>
Because the first integer is 63 then the third would be <span>x+2</span> or <span>63+2=<span>65</span></span>
