A pool pass costs $30 for the first month and $15 each additional month. Construct an explicit rule in function notation to mode

noname [10]

Answer:

$F(n)=15(n+1)$ [ where $n$ is number of months]

$F(12)=195$

Step-by-step explanation:

Pool pass cost for first month =$30

Pool pass cost after first month = $15 for each month

The total amount charged by the pool can be expressed as a function $F(n)$ where $n$ represents the number of months.

$F(n)=15(n-1)+30$

This can be simplified by using distribution.

$F(n)=(15n-15)+30$

$F(n)=15n-15+30$

$F(n)=15n+15$

Take 15 as greatest common factor.

∴ $F(n)=15(n+1)$

For $n=12$

$F(12)=15(12+1)$

$F(12)=15(13)$

$F(12)=195$

∴ Amount charged by pool for 12 months = $195

Find the midpoint of points A(-2,-8) and B(7,-4) graphically.

k0ka [10]

Answer:

The midpoint is (2.5,-6) or written as a fraction ( $\frac{5}{2}$ , -6)

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2}),(\frac{y_1+y_2}{2} ) \\MP= (\frac{-2+7}{2}),(\frac{-8+-4}{2} ) \\MP= (\frac{5}{2}),(\frac{-12}{2} ) \\MP= (2.5,-6 )$
