Answer:444
Step-by-step explanation:
1/2 time base times height times 4
And then base times height times 4
add them together
I got 70
Combination=n!/((n-r)!r!)
=8!/((8-4)!*4!)
=8*7*6*5*4!/(4!*4!)
=8*7*6*5/(4*3*2)
=70 ways
Oooooooonnnnnneeeeeeeemmmmmmmmiiiiilllllllliiiiieeee
Answer
when you place a source of signal at a focal point of an ellipse, the signal will be reflected to the other focal point position
When you place a source of rays as a signal at the focal point of a hyperbola, the ray will be reflected directly away from the other focal point
When you place a source of rays as a signal at one of the parabola focus, the ray will be reflected in lines that are parallel to the axis of the parabola.
That's a good question. When comparing negative numbers the lower one has a greater 'number part ( without the sign)' then the higher one.
For example -4 and -10:- 10 > 4 but -4 > -10.
