1) this is total area of two triangle
area of a triangle=1/2*b*h
A=1/2*9*4
A=18 inches^2
multiply by 2 because there are two triangle with same measure
2A=2*18=36 inches^2
3) this is a area of rectangle and a triangle and then subtract
A2=9.3x7.8= 72.54
area of triangle A1=1/2*7.8 *3.3=12.87
A2-A1=59.69 mm^2
5) now u ca do it
The correct answer is d.
You can start by narrowing down your answer choices by taking out a & b. Since there is a reduction your graph will have a negative slope. Then you can consider the fact that your first point will start on week 3 at 391, meaning week one would need to be a higher point than that, leaving you with d.
Answer:
Most likely the table will contain one pair of values that correspond to the coordinate where the previous lines intersect.
Step-by-step explanation:
It may be possible that the table before the third line contains values on either side of the point of intersection, but the slope will produce a line that connects those values and passes through the previous intersection.
Pretty sure you'd use the decay formula y = b(1-r) so y = 20,000(1-0.25) which equals $6328
The t and the 4 are supposed to be superscripts
