Answer:
Step-by-step explanation:
Here is the complete question: 28 elementary schools to 16 middle schools, write the ratio in simplest form.
Given ratio= elementary schools: middle schools:: 28:16
The ratio can be written as 
Now to write into simplest form, we need to divide both numerator and denominator by 4.
∴ elementary schools: middle schools= 
Hence, we get simplest ratio of elementary schools to middle schools=
anaalyze the problem
first term: -1
common difference: +9 (8-(-1) is 9)
so, an=-1+9n-9
answer is an=9n-10, with n bigger or equal to one
sixth term,plug in 9(6)-10=54-10=44
tenth term, plug in 9(10)-10=90-10=80
Hey there!
When you write an equation in function notation, one side of the equation is, "f(x)".
You can replace x with another variable such as n if you are using a different one.
f(x) takes the place of y in an equation.
For example, the equation y = 3x + 2 in function notation is f(x) = 3x + 2.
Hope this helps!
We are given
equation of position
Calculation of velocity:
we can find derivative
so, velocity is
now, we can set it to 0
and then we can solve for t
Calculation of acceleration:
we can find derivative again
so, acceleration is
now, we can plug value of t
