Answer:
Take the square root of each side
D (x+b/2a) =±sqrt( (b^2-4ac)/ 4a^2)
Step-by-step explanation:
We have
(x+b/2a) ^2 = (b^2-4ac)/ 4a^2
We need to take the square root of each side to continue to isolate x
(x+b/2a) =±sqrt( (b^2-4ac)/ 4a^2)
I hope thats right
Answer:
- <u>Surface Area = 399.4 m²</u>
- <u>Volume = 1675.5 m³</u>
Step-by-step explanation:
<u>Lateral Surface Area of the Cylindrical Part</u>
- 2πrh
- 2 x π x 5 x 8
- 80 x π
- 251.3 m²
<u>Slant height of cone</u>
- √r² + h²
- √25 + 64
- √89
- 9.43 m
<u>Surface Area of Conical Portion</u>
- πrl
- π x 5 x 9.43
- 47.15 x π
- 148.1 m²
<u>Total Surface Area</u> :
- 251.3 + 148.1
- <u>399.4 m²</u>
<u></u>
<u>Volume</u>
- V = πr²h + 1/3πr²h
- V = πr²h (1 + 1/3)
- V = π x 25 x 8 x (4/3)
- V = π x 1600/3
- V = <u>1675.5 m³</u>
Answer: 20 weeks
Step-by-step explanation:
12,500- 2,500= 10,000
10,000 x .25= 2,500
2,500= 125x
2,500/125= 20
