Remark

You are dealing with a right angle triangle. You can use one of Sin(x) Cos(x) or Tan(x). Since the Hypotenuse is involved and since you are given the adjacent side, Cos(71) is what you will need.

Solution

H = BC

Cos(x) = adjactent / hypotenuse

Cos(71) = 6.3 / H            Multiply both sides by H

H * Cos(71) = 6.3            Divide by Cos(71)

H = 6.3 / cos(71)             Cos(71) = 0.32557

H = 6.3 / 0.32557          Divide

H = BC = 19.351                       Answer

Please quickly help!! I will Mark brainliest, What is the inverse of the function f(x) = x +3? Thank you!
Irina18 [472]

Answer:

Mark me as Brainliest

fx^{-1} (x)=x+3

Step-by-step explanation:

To find the inverse of a function, just “trade” x and y and solve for the “new” y. The graph of the inverse is the reflection of the original function over the line y=x.

Rewrite the function

f(x)=x+3

as the equation, y=x+3

Trade x and y.

X=y+3

The symbol for the inverse if fx^{-1} (x)

fx^{-1} (x)=x+3

Javier had $305in his bank account. His bank charges a fee of $7.50each month that a balance is below $500.
Mama L [17]

Answer:

Javier’s account has $282.5 at the end of the three months.

Step-by-step explanation:

final = initial - 7.5x

initial is the initial amount of money in the account, so 305. x is the number of months that have passed. Since Javier doesn't deposit any more money durning that time, the amount in the bank will always be less than 500 we don't have to consider anything else. We just sub initial with 305 and x ( the number of months) with 3 to get the answer. So,

final = 305 - 7.5 * 3 = 282.5
