Answer:

A) in the relationship the rates of go cost course is given by d=2

So Since, the cost of

1. Lap= 2 $

2.Lap= 2 x 2 = 4 $

3.Lap= 4 + 2 = 6 $

4.Lap= 6 + 2 = 8 $

B) The (n) term of the sequence 2,4,6,8,... with, a,= 2,d= 2 is

a(n) = a,1 + (n - 1)d Write the formula

a(n) = 2 + (n - 1)2 Substitute values

a(n) = 2 + 2,n-2 Simplify

a(n) = 2n

Therefore, the (n) term of the sequence is a(n) = 2(n)

Answer:

$\begin{gathered} \text{ A tray of club sandwiches cost \$9} \\ A\text{ tray of vegetarian sandwiches cost \$6.} \end{gathered}$

Step-by-step explanation:

Given the information, create the following augmented matrix:

The first order was for 1 tray of club sandwiches, at a cost of $9. The second-order, which cost $69, was for 5 trays of club sandwiches and 4 trays of vegetarian sandwiches.

$\begin{gathered} 5x+4y=69 \\ x=9 \end{gathered}$

Into an augmented matrix:

$\begin{bmatrix}{5} & {4} \\ {\placeholder{⬚}} & {1}\end{bmatrix}\begin{bmatrix}{69} & {} \\ {9} & {}\end{bmatrix}$

Solve.

Let x be the cost of a tray of club sandwiches.

Let y be the cost of a tray of vegetarian sandwiches.

$\begin{gathered} x=9 \\ Substitute\text{ on the first equation} \\ 5(9)+4y=69 \\ 4y=69-45 \\ y=\frac{24}{4} \\ y=6 \end{gathered}$

I need help with this one I’m not sure if I got it right

Answer:

144 feet

Step-by-step explanation:

Since this is a quadratic equation, we simply need to find the vertex in order to determine the maximum height!

To solve the equation, follow these steps!:

$0 = 16t^2+96t\\\\\frac{-b}{2a} =x\\\\\frac{-96}{2(-16)}=3=x$

Now we insert x back into the equation...

$= -16(3)^2+96(3)\\ = -16(9)+288\\ =-144+288\\=144$
