Aaron knows that the equation pH=−log[H+] can be used to calculate the pH level of a solution. Solutions with a pH value less than 7 are acidic; solutions with a pH value that is greater than 7 are basic; and solutions with a pH value of 7 are neutral. Aaron makes a table of values that he wants to use to graph the function. Fill in the missing values in the table. pH [H+]
? 1
? 10^−7
? 10^−14

sec ф = 5/3 (quadrant 4)

let x = base

y = perp

z = hypotenuse

sec ф = hypotenuse/base = 5/3

⇒ z = 5 and x = 3

finding y:

z² = x² + y²

5² = 3² + y²

y² = 25-9

y² = 16

y = 4

now finding all other geometric functions of theta:

sin ф = y/z = 4/5

sin ф = -4/5 (sin is negative in the 4th quadrant)

cos ф = x/z = 3/5

cos ф = 3/5 (cos is positive in 4th quadrant)

tan ф = y/x = 4/3

tan ф = -4/3 (tan is negative in 4th quadrant)

cosec ф = z/y = 5/4

cosec ф = -5/4 (cosec is negative in the 4th quadrant)

cot ф = x/y = 3/4

tan ф = -3/4 (tan is negative in 4th quadrant)

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

f is the midpoint of
