H(x)=1/8x^3-x^2<br><br> Over which interval does h have a positive average rate of change?
lara31 [8.8K]

Answer:

(-\infty,0)\cup(\frac{16}{3},\infty)\\That \ is x\frac{16}{3}

Step-by-step explanation:

h(x)=\frac{1}{8}x^{3} -x^{2} \\\\Differentiate \ h(x) \ with \  respect \ to \ x\\h'(x)=\frac{3}{8}x^{2} -2x

For positive rate of change h'(x)>0

\frac{3}{8} x^{2} -2x>0\\x(\frac{3}{8}x-2)>0\\\\ When \ x0 \ (multiplication \ of \ two \ positives \ is \ positive)\\\\h'(x)>0 \ when \ x\frac{16}{3} \\\\

What is the solution for the equation 14.8 equals n -0.3
vodomira [7]

Hello there!

14.8=n-0.3

Answer:

\boxed{n=15.1=15.0}

You can also round up to the nearest tenths is 15.1 to 15.0 and its going to be stay.

Step-by-step explanation:

First you had to switch sides of equation form.

n-0.3=14.8

Then you add by 0.3 from both sides of equation form.

n-0.3+0.3=14.8+0.3

And finally, simplify by equation. You can also cross out by -0.3+0.3 and it gave us equal to zero. Then you add 14.8+0.3 and it equal to 15.1. You had to used their variable and its should be the right answer.

n=15.1

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Hi, does anyone know the answer to this question? I’m bad at geometry and I’m struggling to answer it.
arsen [322]

Answer:

QT = 16

Step-by-step explanation:

ΔQRS ~ ΔQRT

In similar triangles, corresponding angles are in same ratio.

\frac{QS}{QR}=\frac{QR}{QT}\\\\\frac{25}{20}=\frac{20}{QT}

Cross multiply,

QT * 25 = 20 * 20

QT =\frac{20*20}{25}\\\\QT = 4*4\\\\QT = 16
