12x + 5 - 4x + 2x² =
= 2x² + 12x - 4x + 5 = <u>2x²</u><u> </u><u>+</u><u> </u><u>8x</u><u> </u><u>+</u><u> </u><u>5</u>
Summarizing the question,
Principle(P)=$100
Rate (r)=12%=0.12
Amount (A)=3×P=$300
Time=t=?
n=no of times the interest is compouned per year=4
Then,
A=P{(1+r/n)}^(n×t)
or,300=100×{1+0.12/4}^(4×t)
or,300/100=(1+0.03)^(4×t)
or,3=1.03^(4×t)
Taking log on both sides,
log3=log[(1.03)^(4×t)]
or,log3= (4×t)×log(1.03)
or,4t=log3/log(1.03)
or,t=log3/[4×log(1.03)]
or, t=9.29175...
t=9.3 years ANS!!!

Answer:
The answer to your question is 628 cm³
Step-by-step explanation:
Data
Cylinder Cone
Volume = 1884 cm³ Volume = ? cm³
radius = ? radius = ?
height = ? radius = ?
Process
1.- Write the formula to calculate the volume of a cylinder and a cone.
The Volume of a cylinder = πr²h
The Volume of a cone = 1/3πr²h
2.- If we observe the formula we notice that they are the same just the volume of a cone is the third part of the volume of a cone.
3.- Find the volume of a cone
Volume of the cone = 1/3(1884)
Volume fo the cone = 628 cm³
30b³ + 20b² + 15b + 10 = ...(:5)
6b³ + 4b² + 3b + 2 =
6b³ + 3b + 4b² + 2 =
3b(2b²+1) + 2(2b²+1) =
(2b²+1)*(3b+2)
