Give an approximation of underroot(3) correct to hundredths. (Round to two decimal places as needed.)

Igoryamba

Answer: 1.75

Step-by-step explanation:

To find the value of $\sqrt{3}$

$\text{Let , }y=\sqrt{x}$

$\text{And Let x = 4 and }\Delta x=-1$

Now,

$\Delta y=\sqrt{x+\Delta x}-\sqrt{x}\\\\=\sqrt{3}-\sqrt{4}=\sqrt{3}-2\\\\\Rightarrow\ \sqrt{3}=\Delta y+2$

Since dy is approximately equals to $\Delta y$ then ,

$dy=\dfrac{dy}{dx}\Delta x\\\\=\dfrac{1}{2\sqrt{x}}\times(-1)=\dfrac{1}{2\sqrt{4}}\times(-1)=-0.25$

Thus , the approximate value of $\sqrt{3}=-0.25+2=1.75$

The time it takes to clean up after an anniversary party varies inversely as the number of people cleaning. If 3 people work tog

Norma-Jean [14]

Answer:

54minutes

Step-by-step explanation:

Let the time taken to clean up be t

Let the number of people cleaning be n

If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;

t = k/n

k is the constant of proportionality

If 3 people work together to clean, and took them 90 minutes, this means

at t = 90, n=3

Substitute

90 = k/3

k = 3×90

k = 270

To et the time it will take 5people to clean, the will say;

t =k/n

t =270/5

t = 54 minutes

Hence it will take 5 people 54minues to clean

Diamonds have a density of 3.5 LaTeX: \frac{g}{cm^3}g c m 3. How big is a diamond that has a mass of 0.10 g?

liubo4ka [24]

For this case we have that by definition, the density is given by:

$d = \frac {M} {V}$

Where:

M: It is the mass of the diamond

V: It is the volume of the diamond

According to the data of the statement we have:

$d = 3.5 \frac {g} {cm ^ 3}\\M = 0.10 \ g$

So the volume is:

$V = \frac {M} {d}\\V = \frac {0.10 \ g} {3.5 \frac {g} {cm ^ 3}}\\V = 0.02857\\V = 0.03 \ cm^3$

Thus, the volume of the diamond is approximately $0.03 \ cm ^ 3$

Answer:

$0.03 \ cm ^ 3$

The fair market rental rate for Columbus was $730 in 2013 and $551 in 2003. Find the rate of change for rent in Columbus during

coldgirl [10]

Answer:

The rate of change is <em>17.9 dollars per year</em>.

Step-by-step explanation:

We use the rate of change formula: $\frac{y2-y1}{x2-x1}$ where y2 and x2 and the y and x points respectively of the second point, and y1 and x1 are the y and x points respectively for the frist point.

In our case, the first point's x is 2003 (earlier date) and y is 551 (price).

The second point's x is 2013 (date) and y is 730 (price).

Plugging in the numbers, we get $\frac{730-551}{2013-2003} = \frac{179}{10} = 17.9$

This means the rate of change is 17.9 dollars per year.
