Tan60=x/12 12tan60=14.3 so area formula: 85.8
Answer:
Sketch the graph of y=7^x
Reflect the graph across the y-axis to show the function y=7^-x
Stretch the graph vertically by a factor of 3 to show the function y=3*7^-x
Shift the graph up 2 units to show the function y=3*7^-x+2
Step-by-step explanation:
Do you know how to graph the equation 2x-1?
If you do then graph it.
After, check the inequality - it is Y is less than the equation so you will be filling in everything below the line you graphed
IF you don't know how to graph:
You will have a line that goes up 2 then right 1
The equation is really 2/1 x as in 2 right 1 right
The line will start from y=-1 or 1 right below 0,0 because of the -1 at the end of the equation and the line will travel in both direction for infinity (Or as big as the graph is)
So start at y=-1 then go up 2, right 1 and place a point. Keep doing that (down 2 left 1 when going in the opposite direction) Finally just make a line through all those points you made
The midpoints of the sides are:
M ( (2a+0)/2 , (2b+0)/2 ) = ( a , b )
N ( (-2a+0)/2 , (2b+0)/2 ) = ( - a, b )
P ( (-2a+0)/2, ( -2b+0)/2 ) = ( - a, - b )
Q ( (2 a+0)/2) , (-2b+0)/2 ) = ( a , - b )
The midpoints of a rhombus determine a rectangle.
