I would first suggest turning them all to one thing, like all decimals, or fractions. I chose decimals.
5.2, -5.6, 3.9, √21. To solve the square root, you have to simplify it. There is the square root of 3, times the square root of 7 which gets 21. These can't be simplified, so we can't simplify through that. But, the closest whole number that is a square root is 16. You can check by multiplying the same number together twice. Doing this will get you about 4.58
5.2, -5.6, 3.9, and ≈ 4.58. This is a simple ordering problem now.
It ends up as -5.6, 3 9/10, √21, 5.2
There are 2 decimals, one negative. There is one square root, and one mixed number. The square root is an infinite decimal when simplified
Hope this helps! ~Malachi
Answer:
7x-5
Step-by-step explanation:
x-5(5x-1) becomes 6x-5+1x-5. Once you simplify that, you get 7x-5.
Answer:
we would need the table that is above to answer this question.
Step-by-step explanation:
Is this suppose to be a question if so give me more information. But 9+9=18
Answer:
Step-by-step explanation: h(t) = -16t2 + 144
h(1) = -16(12) + 144 = 128 ft
h(2) = -16(22) + 144 = 80 ft
h(2) - h(1) = 80 - 128 = -48 ft
It fell 48 ft between t = 1 and t = 2 seconds.
It reaches the ground when h(t) = 0
0 = -16t2 + 144
t = √(144/16) s = 3s
It reaches the ground 3s after being dropped.
