Answer:

The volume of the cone is 108π(pi). if the height is 9

Step-by-step explanation:

V = πr2h / 3 (formula for finding the volume)

V = π62(9) / 3

V = 324π / 3

V = 108π

You can change the value of height if its different for you

-2|3x+2| = -12

|3x+2| = 6

3x + 2 = 6

3x + 4

x = 4/3

|3x+2| = -6

3x +2 = -6

3x = -8

x = -8/3

So we have the answers being 4/3 and -8/3

Differentiate with respect to x : 2xe^x

Gnom [1K]

$\\ \sf\longmapsto \dfrac{d}{dx}2xe^x$

Apply product rule

$\\ \sf\longmapsto \dfrac{d}{dx}2x(e^x)$

$\\ \sf\longmapsto 2x\dfrac{d}{dx}e^x+e^x\dfrac{d}{dx}2x$

$\\ \sf\longmapsto 2xe^x+2e^x$

$\\ \sf\longmapsto 2e^x(x+1)$

Which statement BEST describes the growth of bacteria modeled by the function f(x)=1.8x

lara [203]

Answer:

Step-by-step explanation:

f(x) = 1.8x is a linear function and does not model the growth of bacteria. Perhaps you meant f(x) = 1.8^x, which is an exponential function whose initial value is 1. Please ensure that you have copied down this problem exactly as it was presented.
