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

Whats the answer to this?

mina [271]

instead of P+2x = y it should be P-2x=y

so then it is P-2x/2 =y

A square has a side length of at+b. What is the perimeter of the square if t =c,simplified? A=7 B=10 C=9

EastWind [94]

The perimeter would probably be 292 because at+b is 7(9)+10, or 73 and there are 4 sides of a circle, so 73 times 4 is 292.

4. Determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Ierofanga [76]

Answer:

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

Step-by-step explanation:

Given

Given that the function f(x) and g(x) are inverse functions.

$f\left(x\right)\:=\:\frac{1}{3}x\:+\:5$

$g(x) = 3x - 15$

To determine

Let us determine whether f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.

<u>Determining the inverse function of f(x) </u>

A function g is the inverse function of f if for y = f(x), x = g(y)

$y=\frac{1}{3}x+5$

Replace x with y

$x=\frac{1}{3}y+5$

Solve for y

$y=3x-15$

Therefore,

YES! we conclude that f(x) = 1/3x + 5 and g(x) = 3x - 15 are inverse functions.
