Pomozcie : ( w morzach zyje wiele duzych zwierzat. np. orka wazaca 7000kg , jest znacznie ciezsza od zyrafy wazacej 1400kg a nawet od slonia wazacego 6000kg , jednak w srodowisku morskim, orka wcale nie nalezy do olbrzymow. rekin wielorybi jest od niej 2 razy ciezszy a najwiekszy z wielorybow, pletwal blekitny jest 10 razy ciezszy od rekina wielorybiego. a) oblicz wage kazdego z wymienionych zwierzat morskich. b) ile razy ciezsza jest orka od zyrafy? o ile kilogramow jest ciezsza? c) ile razy ciezszy od orki jest pletwal blekitny? a ile razy jest on ciezszy od zyrafy?

Which of the following equations is of the parabola whose vertex is at (4, 3), axis of symmetry parallel to the y-axis and focus at (4, -3)? a.) y+3=1/24 (x+4)^2 b.)y-3=-1/24 (x-4)^2 c.)x-4=-1/24 (y-3)^2

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

Ascientist places 24 cells in a petri dish. she knows the cells grow at an exponential rate, doubling in number every hour. how long will it take (in hours) for there to be 1100 cells in the dish? time to 1100 cells: 5.51832530 hours how long will it take to reach 110 cells? time to 110 cells : 2.1963972 hours what is the average rate of change in the number of cells between 9 hours and 11 hours? average rate of change: cells per hour what is the instantaneous rate of change after 7 hours? instantaneous rate of change: cells per hour note: you can earn partial credit on this problem.
