Slope is 1/2. The equation to solve it is y2-y1 / x2-x1. I hope you understand it now :)

For a cube whole side lenght is 4 in , the expression 4 to the 3 could represent
S_A_V [24]

Answer:

Step-by-step explanation:

The volume of a cube.

The formula is V = s^3 where is the the "whole side length" of the cube. The cube requires three dimensions be multiplied together to find its volume.

That's why the formula is written as V = s^3. It means that V = s * s * s which is three sides multiplied together. They also need to be at right angles to each other.

Find cos 18, sin 18. cos 3x=sin2x then x=18.
Rzqust [24]
X = 18°
cos 54° = sin 36°
cos 3 x = sin 2 x
cos ( 2 x + x ) = sin 2 x
cos 2 x cos x - sin 2 x sin x = 2 sin x cos x
( cos² x - sin² x ) cos x - 2 sin² x cos x = 2 sin x cos x   / : cos x
                                                                         ( divide both sides by cos x )
cos² x - sin² x - 2 sin² x = 2 sin x
1 - sin² x - 3 sin² x - 2 sin x = 0
- 4 sin² x - 2 sin x + 1 = 0               substitution:  u = sin x
- 4 u² - 2 u + 1 = 0
u = 2 -√20 / - 4        sin 18° =  (√ 5 - 1 )/4 
sin 18 =  \frac{ \sqrt{5} -1 }{4}
cos 18° = √( 1² - ((√5 - 1)/4)²
cos 18° = (10+2√5)^(1/2) / 4

3 times a number x, subtracted from 18 is less than -90
Shalnov [3]

Answer:

x > -24

Step-by-step explanation:

18 - 3x < 90

Subtract 18 from both sides.

-3x < 72

Divide both sides by -3. (When diving by a negative, flip the sign.)

x > -24
