Answer:

The height is 0 when it "drops".

3/2x + 9 = 0

3/2x = -9

3 = -9(2x)

3 = -18x

3/-18x

Change signs, time cant be negative.

x= 6

Another interpretation; Slope is negative it is falling. This interpretation is more accurate.

-3/2x + 9 = 0

-3/2x = -9

-3 = -9(2x)

-3 = -18x

6 = x

A stone is an English measure of weight. There are 14 lb in 1 stone and 2.2 lb in 1 kg.
AveGali [126]
We should use lb to convert weight to kg

let unknown lb be = X
14 lb = 1 stone
X lb = 9 stone
Cross multiply : X × 1 = 9 × 14
X = 126 / 1 = 126 lb

9 stone = 126 lb
let unknown value of kg be = Y
2.2 lb = 1kg
126 lb = Y kg
Cross multiply : 2.2 × Y = 126 × 1
Y = 126 / 2.2 = 57.3 kg

So 9 stone = 126 lb = 57.3 kg

HOPE IT HELPED !!

Express cos(27pi/8) as a trigonometric function of an angle in Quadrant I.
Kryger [21]

Answer:

The equivalent trigonometric ratio in Quadrant I is -\cos (\frac{3\pi}{8})

Step-by-step explanation:

The terminal side of \frac{27\pi}{8} is in the 3rd quadrant.

The principal angle is \frac{3\pi}{8}

In other words, the terminal side of \frac{27\pi}{8}  makes an acute angle of \frac{3\pi}{8} radian with the positive x-axis. Acute angles are in the first quadrant.

Since the cosine ratio is negative in the 3rd quadrant,

\cos (\frac{27\pi}{8})=-\cos (\frac{3\pi}{8})
