8 0

The greatest common factor is the highest number that divides exactly into two or more numbers.

15: 1, 3, 5, 15 

90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 

The GCF for 15 and 90 is 15.

H(x)=1/8x^3-x^2 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 $h'(x)>0$

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

Which planet is an inner planet, and which one is an outer planet? Explain your answer.

Paraphin [41]

Answer:

Planet A is an outer planet, and planet B is an inner planet. Inner planets rotate slowly, so they take more time to complete a rotation. Outer planets rotate faster, so they take less time to complete a rotation.

a rectangular playground is 40 meters by 10 meters. its area will be covered with shredded tires. each bag of shredded tires cov

Lena [83]

First, we need to find the area of the rectangular playground.
To do this, we must multiply 40 by 10.
We get 400 meters².
Now divide 400 by 200 and you get 2.
That means 2 bags will be needed to cover the entire area of the playground.
To find the price, multiply 30 by 2.
The total cost for this project will be $60.
Hope this helped you out! :)

What is the error in the proof? The error is in step 3. The reason should be the quotient property of exponents. The error is in

galina1969 [7]

Answer:

The error is in step 3. You cannot use a property of logarithms to prove that same property.

Step-by-step explanation:

Here we the proof of the quotient rule as

If Logₐx = M and Logₐy = N

Then x = $a^M$ and y = $a^N$
