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 $h'(x)>0$

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

I need some help. I don’t know how to do this<br> Find the value of x

Roman55 [17]

The value of x in the triangle is 50

The angles in a triangle add up to 180.

So, we have:

x + x + 2x - 20 = 180

Add 20 to both sides

x + x + 2x = 200

Evaluate the like terms

4x =200

Divide both sides by 4

x =50

Hence, the value of x in the triangle is 50

At an ice cream parlor ,ice cream cones cost $1.10 and sundaes cost $2.35 one day the receipts for a total of 172 cones and sund

LUCKY_DIMON [66]

88 cones were sold.

Step-by-step explanation:

Let,

Cones = x

Sundaes = y

Cost of one cone = $1.10

Cost of one sundae = $2.35

According to given statement;

x+y=172 Eqn 1

1.10x+2.35y=294.20 Eqn 2

$Multiplying\ Eqn\ 1\ by\ 1.10\\1.10x+1.10y=189.2\ Eqn\ 3\\Subtracting\ Eqn\ 3\ from\ Eqn\ 2\\(1.10x+2.35y)-(1.10x+1.10y)=294.20-189.2\\1.10x+2.35y-1.10x-1.10y=105\\1.25y=105\\Dividing\ both\ sides\ by\ 1.25\\\frac{1.25y}{1.25}=\frac{105}{1.25}\\y=84$

Putting value of y in Eqn 1;

$x+84=172\\x=172-84\\x=88$

88 cones were sold.
