Answer:-5
Step-by-step explanation:
Answer:
B. $2862
Step-by-step explanation:
Using n=5 in the given equation, we get ...
A(5) = 2700 + (5-1)(.015·2700) = 2700 +4(40.50)
A(5) = 2862.00
In year 5, you will have $2862 in the account.

<em>Comment on the given equation</em>
The given equation tells you the amount in the account at the <em>beginning</em> of the year, before it earns any interest. Since that is the equation given, we presume that is the answer desired. In most "account balance" problems, you are interested in the amount at the <em>end</em> of the interest-earning period.
Answer:
$32
Step-by-step explanation:
Since the question says that all the apples were sold for a total of $160, this means that you have to add the additional basket of the friend's to Olivia's. Since Olivia has 4 baskets of apples and her friend has 1, 4+1=5. Since you're trying to find the unit price for 1 basket, you take the total of $160 and divide it by 5 to find how much each basket of apples costed. Since 160/5 is 32, $32 is your answer.
The part in the question where it says, "angle of elevation from the tip of a building is 70 degrees" means that from a specific point away from the building, if you were to connect that point to the top of the building, that line will make a 70 degree angle with the ground. we also know that specific point is 180 feet from the base of the building. this calls for some trigonometry.
the h (height of the building) is a side length opposite to the 70 degree angle, and we know the side length adjacent to the 70 degree angle is 180. if you're confused about what im saying, draw the picture out. this motivates us to use tan. doing so gives:
tan70 = h/180
now we can solve for h to get:
h = 180tan70
h = 494.55
make sure that your calculator is in degree mode, not in radian mode!!!
