Answer:
$1,075
Step-by-step explanation:
Use the formula I=PRT where I= interest, P=principle or starting amount, R=interest rate, T=time
1000*0.025*3=75
Add 75 to 1,000, 1,000+75=1,075
66 is 15% of what amount....
66 = 0.15x
66/0.15 = x
440 = x......so $ 66 is 15% of $ 440
You have to go at this in a round-about fashion...by finding the length of the leg across from the 67 degree angle. This is found by using the tangent ratio...Tan(67)=x/137; x=137tan(67) = 322.8. Now you can use this in one of two ways: use Pythagorean's Theorem to find the length of the hypotenuse OR you could use the sin67=322.8/x. Up to you. Either way, make sure you have your calculator in degree mode!
Subtracting 2 from the original equation moves the graphed line 2 units down.
