4374. You can draw 54 lines horizontally and 81 vertically, and count the intersections of the lines. Is this what your talking about? Not very efficient, I might add.
Answer: The bottom left option.
Step-by-step explanation:
←XY→ is the line that connects the points X and Y.
The fact that the planes C and D intersect at this linea, means that all the points where the planes are intersecting are points in the given line.
Then the correct option is the bottom left one, because the planes D and C are intersecting in a line, and the line passes through the points X and Y, so that line is called ←XY→.
Answer:
to find compound interest
it is
p(1+r) ^n
p stands for principa
r is the rate (percentage)
n is the amount of years
820(1+3.5 ) ^ 5
100
chsnge the percentsge to a decimal and add it to 1.
820(1 + 0.035) ^ 5
820(1.035)^5
raise what is in the bracket to the power of 5 which is the amount of years
820× 1.19
=£975.80
im not good with simple interest,could someone else show her how to do it please
