What is the range of the function f(x) = –2|x + 1|

Oduvanchick [21]

Answer:

$f\left(x\right)\le \:0$

Step-by-step explanation:

$\mathrm{The\:range\:of\:an\:absolute\:function\:of\:the\:form}\:-c|ax+b|+k\:\mathrm{is}\:\:f\left(x\right)\le \:k$

$f(x) = -2|x + 1|+0$

$k=0$

$f\left(x\right)\le \:0$

Hard I need help plz someone help!

Leona [35]

Answer:

8 gallons

Step-by-step explanation:

Each rectangular face of the monument has an area of ...

A = bh = (9 ft)(39 ft) = 351 ft^2

The triangular face on top of that rectangle has an area of ...

A = (1/2)bh = (1/2)(9 ft)(10 ft) = 45 ft^2

So, one side of the monument has an area of ...

one side = (351 ft^2) +(45 ft^2) = 396 ft^2

The total area of all four identical sides is ...

surface area = (4)(396 ft^2) = 1584 ft^2

Each gallon covers 199 ft^2, to the number gallons required is ...

(1584 ft^2)/(199 ft^2/gal) ≈ 7.96 gal

Since only whole gallons can be purchased, 8 gallons of paint must be bought.

The ratio of hydrogen to oxygen atoms in water molecules is 2 to 1. If the beaker of water contained 4.1 moles of oxygen atoms,

Ad libitum [116K]

Answer:

8.2

Step-by-step explanation:

We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.

We can represent this information as: $\frac{\text{Hydrogen}}{\text{Oxygen}} =\frac{2}{1}$

Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.

Upon substituting our values in above proportion we will get,

$\frac{2}{1} =\frac{x}{4.1}$

$x=2\times 4.1$

$x=8.2$

Therefore, the moles of hydrogen atoms in water beaker will be 8.2.

Pls help I dont understand. Find the inverse of this function.

lisov135 [29]

In the inverse we replace the place of x by y .

$g(x) = \sqrt[3]{x} - 3 \\ \\ x = \sqrt[3]{y} - 3 \\ \sqrt[3]{y} = x + 3 \\ y = {(x + 3)}^{3} \\ y = {(x + 3)}^{2} (x + 3) \\ y = ({x}^{2} + 6x + 9)(x + 3) \\ \\ y = {x}^{3} + 6 {x}^{2} + 9x + 3 {x}^{2} + 18x + 27 \\ \\ y = {x}^{3} + 9 {x}^{2} + 27x + 27 \\ \\ \\ g(x)^{ - 1} = {x}^{3} + 9 {x}^{2} + 27x + 27$

I hope I helped you^_^
