Answer:
n -8.2 = 2.3(t -1)
Step-by-step explanation:
You are given definitions for the variables t and n, along with two data points:
(t, n) = (1, 8.2) and (5, 17.4)
The slope of the line between these points is ...
m = (y2 -y1)/(x2 -x1)
m = (17.4 -8.2)/(5 -1) = 9.2/4 = 2.3
The equation can be written in point-slope form as ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
n -8.2 = 2.3(t -1) . . . . a linear model describing the data
______
<em>Additional comment</em>
If we eliminate the parentheses and add 8.2, we get the point-slope equation ...
n = 2.3t +5.9
Hello from MrBillDoesMath!
Answer:
l = s/3.14 - r^2
Discussion:
s = 3.14 l + 3.14 r^2 => divide both sides by 3.14
s/3.14 = l + r^2 => subtract r^2 from both sides
(s/3.14) - r^2 = l
Thank you,

Answer:
Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.The primary reason for converting numbers into scientific notation is to make calculations with unusually large or small numbers less cumbersome.
