Mrs. Becker is selling tickets to an art exhibit, but she lost the receipts. She knows that she has sold at least 20 tickets. Th

e adult tickets (x) cost $14 and the children’s tickets (y) cost $12. If she knows she has sold no more than $420 worth of tickets, write a system of inequalities to model the ticket sales.

Answer:

x+y≥20
14x+12y≤420

Step-by-step explanation:

Variables are defined in the problem statement.

x + y ≥ 20 . . . . . . . . at least 20 tickets were sold

14x +12y ≤ 420 . . . . sales were at most $420

Find the 12th term of the geometric sequence 5, -25, 125, ...5,−25,125,...

katovenus [111]

Answer:

$a_{12}=-244140625$

Step-by-step explanation:

Considering the geometric sequence

$5,-25,\:125,\:...$

$a_1=5$

As the common ratio ' $r$ ' between consecutive terms is constant.

$\mathrm{Compute\:the\:ratios\:of\:all\:the\:adjacent\:terms}:\quad \:r=\frac{a_{n+1}}{a_n}$

$r=\frac{-25}{5}=-5$

$r=\frac{125}{-25}=-5$

The general term of a geometric sequence is given by the formula:

$a_n=a_1\cdot \:r^{n-1}$

where $a_1$ is the initial term and $r$ the common ratio.

Putting $n = 12$ , $r = -5$ and $a_1=5$ in the general term of a geometric sequence to determine the 12th term of the sequence.

$a_n=a_1\cdot \:r^{n-1}$

$a_n=5\left(-5\right)^{n-1}$

$a_{12}=5\left(-5\right)^{12-1}$

$=5\left(-5^{11}\right)$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$=-5\cdot \:5^{11}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}$

$=-5^{1+11}$ ∵ $5\cdot \:5^{11}=\:5^{1+11}$

$=-244140625$

Therefore,

$a_{12}=-244140625$

Create an exponential function that starts at 650 and increases by 12% us the form f(x) = p (1=r)^x

ololo11 [35]

F(x)= 650(1+.12)^x

f(x) = 650(1.12)^x

Matrix question help needed

kramer

The required matrix is:

$\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]$

Step-by-step explanation:

We need to apply elementary row operation -2R₂+3R₁ tothe matrix:

$A=\left[\begin{array}{ccc}-3&5&2\\8&-1&3\\\end{array}\right]$

Multiplying Row 2 with -2 and Row1 with 3 and adding,

-9 15 6

-16 2 -6

----------

-25 17 0

After applying this operation, Row 1 will be changed while Row 2 will remain same because we get -2R₂+3R₁ -> R₁

The required matrix is:

$\left[\begin{array}{ccc}-25&17&0\\8&-1&3\\\end{array}\right]$
