Answer:

x = 11.01105536

Step-by-step explanation:

Formula:

$\tan = \frac{opposite}{adjacent}$

Replace with given values, so

$\tan(54) = \frac{x}{8}$

Multiply both sides by 8

$8 \times \frac{x}{8} = 8 \times \tan(54)$

Cancel common factor of 8

$x = 8 \times \tan(54)$

Multiply

$8 \times \tan(54)$

Answer:

$x = 11.01105536$

1) The equation of the parallel line in Slope Intercept Form is; y = -x - 1

2) The equation of the perpendicular line in Slope Intercept Form is;

y = ³/₂x - 4

<h3>How to write equation in Slope Intercept Form?</h3>

1) When two lines are parallel, it means their slopes are the same.

Formula for equation in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Thus, slope of y = -x + 1 is m = -1.

Equation of parallel line is;

(y - (-5))/(x - 4) = -1

y + 5 = -x + 4

y = -x - 1

2) When two lines are perpendicular, it means their slopes are the negative inverse of each other. Thus;

Slope of line = -2/3 and so slope of perpendicular line = 3/2. Thus, equation of new line is;

(y + 1)/(x - 2) = 3/2

2y + 2 = 3x - 6

2y = 3x - 8

y = ³/₂x - 4

On which interval is the function decreasing

san4es73 [151]

Answer: Choice B) pi/4 < x < 3pi/4

Graph the function using a graphing calculator. I used desmos which is a free online tool. The graph is shown below as the red curve. The blue region represents the region in which the red curve is going downhill as you read from left to right on the interval from x = pi/4 to x = 3pi/4.
