Answer:
First, you write an explicit formula then plug in the value of n in the formula with the term number you are trying to find, in this case the 13th term.
The steps are in the pictures
the final answer is 121 btw
Answer:
f(x) = -5x +48
Step-by-step explanation:
A fairly easy way to write the equation of the perpendicular line is to swap the x- and y-coefficients, negating one of them. Then choose the constant in the equation to make it true at the given point.
<h3>Swapped coefficients</h3>
In this instance, we find it convenient to leave the coefficient of y as positive.
5y = x -10 . . . . . . original equation
y = -5x +c . . . . . . with coefficients swapped, x-coefficient negated
<h3>New constant</h3>
At the given point, the equation becomes ...
8 = -5(8) +c
48 = c . . . . . . . add 40
<h3>Equation of the perpendicular line</h3>
The equation of the line is then ...
y = -5x +48
f(x) = -5x +48 . . . . . . in functional notation
Answer:
($30s+g)
Step-by-step explanation:
If a caterer offers a package that feeds up to 50 people for $1,500, the amount of packaged that fed one person will be $1500/50 which is $30.
If there is an additional charge of $24.75 on each person, the total amount spent on each person will be $50+$24.75 which is $74.75.
The linear model that represent total amount charge per host s as a function of additional guest will be $30s+g since a person spent $30 plus additional charge of 'g'
