2 cm = 5 feet
1 cm = 2.5 feet
9 cm = 9 * 2.5 = 22.5 feet by
4 cm = 4 * 2.5 = 10.0 feet
1) y-intercept => x = 0, => y = f(0) = 0 - 0 + 0 - 36 = -36
2) x-intercept => y = 0 => factor the function (start by dividing by x -2)
f(x) = (x-2)(x-3)(x-6) =0 => x =2, x = 3, x = 6 (these are the x-intercepts)
3) critical points:
between x = 2 and x = 3, there is a local maximum
between x =3 and x = 6 there is a local minimum
3) Shape.
The function comes growing from - infinity.
In the third quadrant the function is negative (it does not pass throuhg the second quadrant)
It enters to the fourth quadrant intercepting the y-axis at y = -36. It continues growing and intercepts the x-axis at x = 2.
It continues increasing until a maximum local positive value, starts to decrease, intercepts the x-axis at x = 3, continues decreasing, becomes negative, gets a local minimum in the fourth quadrant, starts to increase, intercepts the x-axis at x = 6, becomes positive, and continues growing.
Answer:
$406
Step-by-step explanation:
The amount of interest that Lorenzo's account earns is given by ...
I = Prt
where P is the principal amount ($400), r is the annual rate (1.5%) and t is the number of years (1).
Lorenzo's interest is ...
I = $400·0.015·1 = $6.00
Then the balance in Lorenzo's account at the end of one year is ...
$400 +6 = $406.00
Well, what is the perimeter? Does it tell you what the perimeter is? If not, i can't help:(
