In a scientific notation, you have to put a decimal right after the first number (unless it is a zero). How many times you move the decimal from its original spot determines the answer. If you move the decimal 
forward that means you put a 
negative number

0.00000123 = 1.23 (moved the decimal point 
forward 6 times, so the answer is --->)

Answer:
y = -1/2x -3
Step-by-step explanation:
The steps to solve this include finding the slope of the line and finding the point where the line crosses the y axis.
Slope is Rise over Run or difference of the y values over the difference of the x values.
Rise = difference between -6 and -2 = 4
Run = difference between 6 and -2 = 8
So slope is 4/8.  The line slants downward from left to right so the slope is also negative.  Slope = - 4/8 or simplified to - 1 / 2
To find the y intercept, use the slope-intercept form equation:
y = mx + b where m is your slope and b is the y intercept.  Solve for b and use one or both of your points that you were given along with your slope.
-6 = -1/2(6) + b      OR    -2 = -1/2(-2) + b
-6 = - 3 + b                      -2 = 1 + b
-3 = b                                -3 = b
Now you can use your calculated slope and calculated b to form your equation.
y = mx + b
y = - 1/2x -3
 
        
             
        
        
        
First you have to solve for x. X=32. 
5*32-12=148
148=(3y-8). 
y=52
        
                    
             
        
        
        
Sec= 1/(cos), you can add or subtract 360 degrees from any angle measurement without changing the value of any of the trig functions i.e. 405 degrees= 405-360=45. cos of 45 is sqrt(2)/2 so sec405= 2/sqrroot2
        
             
        
        
        
H=3.4s- start with the problem
20=3.4s- substitute the known number(s)
20/3.4=3.4/3.4 s- divide both sides by 3.4
The answer is about 5.88, your answer should be between 5 and 6
