Answer:
the height is : 2365.48 m
Step-by-step explanation:
hello :
h(t) = − 4.9 t 2 + 211 t + 94 .
the vertex of this parabola is : (-b/2a , h(-b/2a) when : a= -4.9 and b=211
-b/2a = -(211)/2(-4.9) = 21.53
h(21.53) = -4.9(21.53)²+211(21.53)+94 = 2365.48 m

Answer:
2094.5 muffins
Step-by-step explanation:
The problem is a little bit messy, but i’m guessing you meant that the elf ate 35% of the muffins, which 35% is 710 muffins. so since 35% of muffins is 710 muffins, let’s multiply that by 2 so we can get 70%.
so 710 x 2 is 1420. so 70% of the muffins is 1420 muffins! sadly that’s not all of the muffins. we’re still missing another 30%. since we don’t know how many muffins are in 30%, let’s just take 710 muffins - 5%. when you do that you get 674.5. so now that we know how much is in 30%, let’s take 1420 + 674.5. when you do that you get 2094.5! so you started off with 2094 and a half muffins!
