It is approximately -.4048
H=10^(-pH)
log H = -pH
pH=-logH => so it is affirmed that it is -.40
Answer:
Step-by-step explanation:
Value of x should be less than (-6).
x = { .......,-9,-8,-7}
For example:
-15*-7 +80 = 105+80 = 185 >170
Answer: I don’t get it
Step-by-step explanation:
8,000 or 08,080?
180° - 36° - 39° - 33° = <u>7</u><u>2</u><u>°</u>
x° = 180° - 72°
x° = <u>1</u><u>0</u><u>8</u><u>°</u>
So, the value of x is 108°

Answer:
Linear Function
Step-by-step explanation:
Given
The table showing values of x and y
Required
Determine the type of function
To determine the type of function, the table represents;
One will need to determine the table equation.
Start by solving for the slope;
![m = \frac{y_1 - y_2}{x_1 - x_2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_1%20-%20y_2%7D%7Bx_1%20-%20x_2%7D)
When x - 0; y = 0 and When x = 80; y = 60.
This gives
![m = \frac{0 - 60}{0 - 80}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B0%20-%2060%7D%7B0%20-%2080%7D)
![m = \frac{- 60}{- 80}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-%2060%7D%7B-%2080%7D)
![m = \frac{3}{4}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B3%7D%7B4%7D)
The formula is determine as follows;
![y - y_1 = m(x - x_1)](https://tex.z-dn.net/?f=y%20-%20y_1%20%3D%20m%28x%20-%20x_1%29)
When x - 0; y = 0; m = 3/4; This gives
![y - 0 = \frac{3}{4}(x - 0)](https://tex.z-dn.net/?f=y%20-%200%20%3D%20%5Cfrac%7B3%7D%7B4%7D%28x%20-%200%29)
![y = \frac{3}{4}(x - 0)](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B3%7D%7B4%7D%28x%20-%200%29)
Open Bracket
![y = \frac{3}{4}x - 0](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B3%7D%7B4%7Dx%20-%200)
![y = \frac{3}{4}x](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B3%7D%7B4%7Dx)
The above is an example of a linear equation.
<em>Hence; option B answers the question</em>
