Answer:

x = 17.5

Step-by-step explanation:

5/8 = x/28

=> 5(28) = 8x

=> 140 = 8x

=> 8x = 140

=> x = 140/8

=> x = 70/4

=> x = 35/2

=> x = 17.5

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

Pls help being timed and I don’t understand
shepuryov [24]

Answer:

f ( -2 ) = 30

g ( -2 ) = 3

Step-by-step explanation:

when it says f(x) and then has f(-2) - you fill in all x's in the equation with -2.. like this:

f(x) = -7(-2-2) +2                         g(x) = 2(-2)^2 -5

f(x) = -7(-4) +2                             g(x) = 2(4) -5

f(x) = 28 + 2                                g(x) = 8 - 5

f(x) = 30                                      g(x) = 3

hope this helps!!
