Answer:

See description

Step-by-step explanation:

Percent mark up and discount finds the amount price changes to. Percent of change compares two prices to find a percentage of decrease or increase. Percent of change can be negative or positive while generally mark up and discount are only positive. Both find the percentage of change between two prices or costs. But discount and markup give a price while percent change gives a percentage change between prices.

A parallelogram has a base of length 2x + 1 and a height of x + 3 and has an area of

storchak [24]

Answer:

base 7
height 6

Step-by-step explanation:

Using the given expressions, we can write the area as ...

A = BH

42 = (2x +1)(x +3) = 2x^2 +7x +3

2x ^2 +7x -39 = 0

(x -3)(2x +13) = 0

x = 3 or -6.5 . . . . . these values make the factors be zero

In order for the parallelogram to have positive dimensions, the value of x must be 3. So, the base and height are ...

base = 2(3) +1 = 7

height = 3 +3 = 6

Determine all critical points the the function:

romanna [79]

$\bf y=x^2-32\sqrt{x}\implies \cfrac{dy}{dx}=2x-32\cdot \cfrac{1}{2}x^{-\frac{1}{2}}\implies \cfrac{dy}{dx}=2x-\cfrac{32}{2\sqrt{x}}
\\\\\\
\cfrac{dy}{dx}=2x-\cfrac{16}{\sqrt{x}}\implies \cfrac{dy}{dx}=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\\\\
-----------------------------\\\\$

$\bf 0=\cfrac{2\sqrt{x^3}-16}{\sqrt{x}}\implies 0=2\sqrt{x^3}-16\implies 16=2\sqrt{x^3}
\\\\\\
8=\sqrt{x^3}\implies 2^3=\sqrt{x^3}\implies (2^3)^2=x^3\implies (2^6)^{\frac{1}{3}}=x
\\\\\\
2^{\frac{2}{1}}=x\implies \boxed{4=x}\\\\
-----------------------------\\\\
\textit{the other critical point at }\sqrt{x}=0\implies \boxed{x=0}$

What is 16 x 1/6 I really need help with this question please and thank you

Anton [14]

Hey There,

16 * 1/6 = 2 2/3

Instead of just 16, we can put 16 over a 1

16/1 * 1/6

Multiply across

16 * 1 / 1 * 6

= 16 / 6

Simplify

2 2/3
