Find an explicit function rule for the sequence -3, 3, 9, 15,.... Use the formula a(n) = a(1) + (n-1)d and simplify fully.
fiasKO [112]
A(1) = - 3 ;
a(2) = a(1) + ( 2 - 1 )d ;
3 = -3 + d ;
d = 6 ;
a(3) = a(1) + ( 3 - 1)d;
9 = - 3 + 2d ;
12 = 2d ;
d = 6 ;
a(4) = a(1) + ( 4 - 1 )d ;
15 = -3 + 3d ;
18 = 3d ;
d = 6 ;
Then, a(n) = - 3 + ( n- 1 )6 ;
a(n) = - 3 + 6n - 6 ;
a(n) = 6n - 9 is an explicit functin rule for the sequence -3, 3, 9, 15, ...

A school choir needs to make T Shirts for its 75 members and has set aside some money in their budget to pay for them. The membe
aleksandr82 [10.1K]

Answer:

<h2><em>D = 3(75) + 30C</em></h2>

Step-by-step explanation:

If a school choir needs to make T Shirts for its 75 members and the printing company charges $3 per shirt, the total amount paid for shirts without coloured printing will be $3 * 75 = 3(75) ... 1

If the printing company charges $50 fee for each color to be printed on shirts, then the total number of colours on the short will cost $30C.... 2

where C is the total amount of colours on all the shirts.

The equation that will represents the relationship between the number of T-shirts orders, the number of colors on shirts and the total cost of the order will be gotten by taking the sum of equation 1 and 2.

<em>The equation needed will be 3(75) + 30C where C is the total amount of colours on all the shirts ordered.</em>
