The sine function is an odd function

Agata [3.3K]

Sure the sin function is an odd function because sin (-Ф) = - sin (Ф)
Example: sin (- 30°) = - sin (30°) = -1/2

Micah needs $18,500 to purchase a boat. How much money will he need to invest today in a savings account earning 3.2% interest,

charle [14.2K]

We have that every quarter, he will get an 0.8% interest rate. We also have that there will be 14*4=56 periods of repayment. We have that by the formula, if there are n periods and x% is the interest rate, the capital is multiplied by (100+x%)^n.
Suppose Micah invests x money. Then, we have that after 14 years, the capital available will be C= $x*(1.008)^{56}=x*1.562$ . We have that C=18500$ and hence that 18500=x*1.562. Thus, solving for x we have that x=11841$.
Micah will need to invest only 11841$ in order to pay for his boat; this shows the importance of saving since he earns a lot of money, around 7k $.

Tom starts lawn mowing business before he can begin he purchases a new lawnmower each weekend he mows the same number of lawns a

Anastasy [175]

To be able to give the answer to this item, we are to represent first with any variables the amount he earns each weekend for mowing the same field. Also, we represent the number of weeks he had worked by the variable y. The total amount of money he will have after working for y weeks is,

T = xy

Since, we are not given with any other information of the other expenses that have to be paid then we can say that if T is already equal to the price of the new lawnmower then, Tom will be able to purchase it and begin his lawn mowing business in due time.

What is the 7th term of (3x + 2y)9?

Ivan

To get the 7th term of the binomial as written in the given, we first deal with the numerical coefficient of the whole equation and it is given by the equation,
nCk = 9C7
which is equal to 36.

Then, we deal with the first term of the binomial which is 3x.
(3x)^(n-k) = (3x)^(9-7) = 9x²
Then, we deal with the second term of the binomial which is 2y
(2y)^k = (2y)^(7) = 128y⁷

The answer to this item is the product of the three terms,
7th term = (36)(9x²)(128y⁷) = 41472x²y⁷
