The curve described described here is an ellipse with eccentricity e=\dfrac45, the ratio between the distance from the given focus F(4, 0) to any point Q along the directrix x=\dfrac{25}4. Use this info to find the lengths of the semimajor and -minor axes, a and b. Then the area of the ellipse is \pi ab.

Find the area of the region bounded by the given curves. y = 9x2 ln(x), y = 36 ln(x)
oee [108]
Alrighty
find where they intersect

9x²ln(x)=36ln(x)
divide both sides by 9
x²ln(x)=4ln(x)
ln(x^{x^2})=ln(x^4)
so
x^{x^2}=x^4
so x=1 and and 2 (x can't be 0 or -2 because ln(0) and ln(-2) don't exist)

so intersect at x=1 and x=2
which is on top?

9(1.5)²ln(1.5)=20.25ln(1.5)
36ln(1.5)=36ln(1.5)
36ln(1.5) is on top
so

that will be
the area is
\int\limits^2_1 {36ln(x)-9x^2ln(x)} \, dx=
[36x(ln(x)-1)-x^3(3ln(x)-1)]^2_1=
48ln(2)-29

the area between the curves is 48ln(2)-29

two boxes of identical birthday candles are pictured: a 2 ounces box and 6- ounces box. There is 96 candles in the large box. Ho
Sladkaya [172]

Answer:  There are 32 candles in the small box.

Step-by-step explanation:

Since we have given that

Size of small box= 2 ounces

Size of large box = 6 ounces

Number of candles in large box = 96,

We need to find the number of candles in the small box ,

As there is direct variation between the small box and large box ,

let the number of candles in the small box be x

So,

\frac{96}{6}=\frac{x}{2}\\\\16=\frac{x}{2}\\\\16\times 2=x\\\\32=x

so, there are 32 candles in the small box.
