Answer:

This is an arithmetic sequence with a common difference d of -5

Step-by-step explanation:

When you find out d, you realize the difference between the numbers to be -5. Since it is d and not common ratio r, it is an arithmetic sequence.

The length of the rectangle below is (2x-3) and the width is (x+7). Find the area of the rectangle in terms of x.

Alex777 [14]

Answer:

area = 2x² - 17x - 21

Step-by-step explanation:

Area of the rectangle is:

area = (width*length)

area = (x+7)*(2x-3)

= x*2x + x*-3 + 7*2x + 7*-3

= 2x² - 3x - 14x - 21

= 2x² - 17x - 21

In a research laboratory, a scientist measures the mass of a 1-carat diamond and finds it to be 200 milligrams, measured to the

vlada-n [284]

Answer:

$D=3.5\ gr/cm^3$

Step-by-step explanation:

Density

The density of an object of mass m and volume V is given by

$\displaystyle D=\frac{m}{V}$

It can be expressed in common units like $gr/lt, Kg/m^3, gr/cm^3$ or any other combination of proper mass [M] by volume [V] units.

The data provided in the question is

$m=200\ mg = 0.2\ gr$

$V=0.057\ cm^3$

Thus, the measured density is

$\displaystyle D=\frac{0.2\ gr}{0.057 \ cm^3}$

$\boxed{D=3.5\ gr/cm^3}$

We have expressed the result with 1 decimal place because the mass was measured to the nearest hundred milligrams (or one-tenth grams). Any further decimal is senseless because that precision comes from calculations, not from measurements.
