A sliver of gold has a volume of 0.678 cm3. What is the mass of this sliver of gold?

Aliun [14]

Answer - 13.098 gm

Description -

Dear student,

As we know $Density= \frac{Mass}{Volume}$

⇒ Mass = Density * Volume

so multiplying given Volume with the Density of gold ,we can calculate the mass of the gold . Density of gold at room temp. is 19.32 grams per cubic centimeter.

so mass of the sliver of gold = 19.32 * 0.678 = 13.098 (ans)

[2/SEC(¶/3)•[lim x→0 x^3+8x+10]^2]/[lim θ→0 sinθ/θ]

Oliga [24]

Assuming the pilcrow is supposed to represent pi:

$\frac{\frac{2}{sec(\frac{\pi}{3})}*(\lim_{x \to 0} x^3+8x+10)^2}{ \lim_{\theta \to 0} \frac{sine(\theta)}{\theta}}\\\frac{\frac{2}{\frac{1}{cosine(\frac{\pi}{3})}}*((0)^3+8(0)+10)^2}{\frac{sine((0))}{(0)}}\\\frac{\frac{2}{\frac{1}{\frac{1}{2}}}*(0+0+10)^2}{\frac{0}{0}}\\\frac{\frac{2}{2}*(10)^2}{ \lim_{\theta \to 0} \frac{cosine(\theta)}{1}}\\\frac{100}{cosine((0))}\\\frac{100}{1}\\100$

If h (x) = -5x-7 then what is h (x-1) ?

goldenfox [79]

Answer:

h(x - 1) = -5x - 2

General Formulas and Concepts:

Pre-Algebra

Distributive Property

Algebra I

Terms/Coefficients

Functions

Function Notation

Step-by-step explanation:

Step 1: Define

Identify

h(x) = -5x - 7

Step 2: Find

Substitute in x [Function h(x)]: h(x - 1) = -5(x - 1) - 7
[Distributive Property] Distribute -5: h(x - 1) = -5x + 5 - 7
Combine like terms: h(x - 1) = -5x - 2
