A right cone has an altitude of 4 units and a base diameter of 6 units. What is it’s lateral area?
fenix001 [56]

Answer:

Lateral area  =

pi *  (radius) * √ [ height ^2  + radius^2 ]  =

pi *  ( 4 )  * √ [  4^2 + 3^2 ]  =

pi * ( 4 ) * √25  =

pi * ( 4 ) * (5 )  =

20 pi  units^2  ≈   62.8 units^2

Find f if f′(x)=2x−3/x^4, x>0 and f(1)=2.
slavikrds [6]
f'(x)=2x-\dfrac3{x^4}
\displaystyle\int f'(x)\,\mathrm dx=\int\left(2x-\frac3{x^4}\right)\,\mathrm dx
f(x)=x^2+\dfrac1{x^3}+C

Given that f(1)=2, we get

2=1^2+\dfrac1{1^3}+C
2=2+C
\implies C=2

so that

f(x)=x^2+\dfrac1{x^3}

Factor completely 20x^3y + 30x^2y^2.
weqwewe [10]

Answer:

10x^2 y(2x + 3y)

Step-by-step explanation:

20x^3 y + 30x^2 y^2.

Factor 10x^2y out of 20x^3y.

10x^2 y (2x) + 30x^2 y^2  

Factor 10x^2y out of 30x^2y^2.

10x^2 y (2x) + 10x^2 y (3y)  

Factor 10x^2y out of 10x^2 y (2x) + 10x^2 y (3y).

10x^2 y(2x + 3y)

you factor out 10x^2y from both side which you will then get 10x^2 y (2x) + 10x^2 y (3y)  than you factor out 10x^2y again and get 10x^2 y(2x + 3y)  your third option
