If you have ever swum in a pool and your eyes began to sting and turn red, you are aware of the effects on an incorrect pH level
RSB [31]
1. Create a graph of the pH function. Locate on your graph where the pH value is 0 and where it is 1. You may need to zoom in on your graph.
<span>The pH value is 1 at the orange dot, and is 1 at the red dot. </span>
<span>The transformation p(t+1) results in a y-intercept. </span>

<span>In this graph, the blue line is the original and first parent function p(t) = –log10 t. The pink line represent p(t) + 1, the transformation shifts up the y-axis by 1, but the p(t) + 1 transformation does not result in a y-intercept like the ones prior. The gold line represents p(t +1), which shifts horizontally by 1 to the left. This does result in a y-intercept, because the graph doesn't completely flip over the line to the other side, and the green line represents -1*p(t), which causes the graph to flip upside down, and doesn't end up as a y- intercept.</span>

Please help, picture of question included.
Hoochie [10]

Answer:

b. \frac{p-1700}{10}

Step-by-step explanation:

We have that the server's salary can be expressed as

p = $1700+$10t

Counting the $ 1700 dollars as the fixed amount of your salary and contemplating the variable salary that would be $ 10 * t being t the number of overtime worked  

from this expression we can clear the number of overtime worked by clearing t, so I finally have

p=$1700+$10t\\ $10t = p - $1700 \\ t= \frac{p-1700}{10}

Done

[PRECALC] Verify the following trigonometric identity using sin2x + cos2x = 1
frosja888 [35]

Answer:

See below ~

Step-by-step explanation:

Identities :

  1. cot x = cos x / sin x
  2. sin²x + cos²x = 1

Changing the Left Hand Side (LHS) :

  • 1/cot x + cotx
  • 1/(cos x / sin x) + cos x / sin x
  • sin x / cos x + cos x / sin x
  • Take (sin x)(cos x) as the LCM (Least Common Multiple)
  • sin x (sin x) + cos x (cos x) / (sin x) (cos x)
  • sin²x + cos²x / cos x sin x
  • 1/cos x sin x
  • Equal to the RHS

If a polynomial function f(x) has roots 4 – 13i and 5, what must be a factor of f(x)?
Morgarella [4.7K]

The factor of f(x) is (x-(4-13i))

If a polynomial function f(x) has roots 4 – 13i and 5

One of the complex roots is 4-13i

If we have one complex root then there should be one more complex root.

<h3>What is the complex root?</h3>

complex roots come in pairs like (a+ib) and  (a-ib)

so another complex root for 4-13i  is 4+13i

If 'a' is a root then the factor is (x-a)

4+13i is a root

So the factor is (x-(4-13i))
