Wayne and Winston are scuba diving and are ascending to the surface. The function y = 30x − 105 represents Wayne’s elevation in
arsen [322]
The function that represents Wayne´s elevation:
y = 30 x - 105
The function that represents Winston´s elevation:
- 100 = 0 m + b
b = -100
-16 = 3m - 100
3 m = 84
m = 84 : 3 = 28
y = 28 x - 100
Surface level: y = 0
Wayne:
0 = 30 x - 105
x = 3.5 minutes
Winston:
0 = 28 x - 100
x = 3.57 minutes
If they both ascend at the same rate, Wayne will be first to the surface.

Write an equation for the line in the given form.
nexus9112 [7]

Answer:

  5x +y = 34

Step-by-step explanation:

Since a point and slope are given, it is convenient to start with point-slope form, then rearrange the equation to put it into standard form.

For slope m through point (h, k), the point-slope form of the equation of a line is usually written ...

  y -k = m(x -h)

For m=-5 and (h, k) = (6, 4), the equation is ...

  y -4 = -5(x -6)

  y -4 = -5x +30 . . . . . eliminate parentheses

__

Standard form looks like ...

  ax + by = c

where a > 0 and GCD(a, b, c) = 1. Here's how we can get there.

  5x +y -4 = 30 . . . . . . add 5x

  5x +y = 34 . . . . . . . . . add 4 to get standard form.

Given the function f(x) = log3 (x + 1), determine f^−1(2).
zavuch27 [327]
Given:  <span>f(x) = log3 (x + 1), look for f^-1 (2)

We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:

</span><span>f^-1 (2) = 8</span>
