Answer/Explanation:

I agree with the statement because primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance. The first separation of importance is to distinguish between inorganic and organic compounds.

Can someone give me the answers for number 3 ? With explanation please?

Olegator [25]

$6^{51}6^{48} = 6^{51 + 48}= 6^{99}$

$(6^5)^7 = 6^ {5 \times 7} = 6^ {35}$

$6(6^{25}6^{14}) = 6(6^{25+ 14}) = 6(6^{39}) = 6^{39 + 1}= 6^{40}$

$\dfrac{6^{95}}{6^{19}} = 6^{95 - 19} = 6^{76}$

The measure of an angle in standard position is given. Find two positive angles and two negative angles that are coterminal with

devlian [24]

Answer:

13π/4 , 21π/4, -3π/4, -11π/4

Step-by-step explanation:

Coterminal Angles are angles which share the same initial side and terminal sides.

To find coterminal angles, simply add or subtract 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.

5π/4 =(4π/4)+(π/4)

Our Angle 5π/4 is in the 3rd quadrant and exceeds π radians by (π/4) radians, or 45° angular measure.

The 2 positive co-terminal angles would be:

Adding 2π

5π/4 + 2π = 13π/4

Adding another 2π

5π/4 + 2π +2π = 21π/4

The two negative co-terminal angles would be:

Subtracting 2π

5π/4 - 2π = -3π/4

Subtracting another 2π

5π/4 - 2π -2π = -11π/4

The coterminal angles are:

13π/4 , 21π/4, -3π/4, -11π/4

A jewelry company prints a hidden logo watermark. The watermark is a chord that is 0.8 cm from the center of a circular ring tha

Sergeeva-Olga [200]

Answer:

length of chord is 6cm

Step-by-step explanation:

Here, we are to calculate the length of the chord.

It should be understood that the chord has a length of 0.8cm from the center of the circle of radius 3cm, thereby forming two right-angled triangles with the radius 3cm being the hypotenuse of each and 0.8cm being the height of each.

Now, the chord is divided into 2 by this height dropping from the center of the circle. To calculate the first half, we use Pythagoras’ theorem with 3cm being hypotenuse and 0.8cm being the other side.

mathematically;

3^2 = 0.8^2 + l^2

9 = 0.64 + l^2

l^2 = 9-0.64

l^2 = 8.36

l = √(8.36)

l = 2.89 approximately

The length of the chord would be 2l = 2 * 2.89 = 5.78 cm which is 6cm to the nearest length

Use the given confidence interval to find the margin of error and the sample proportion. (0.711,0.739)

tekilochka [14]

Answer:

ME=0.014

Sample Proportion=0.725

Step-by-step explanation:

-The margin of error is defined as the percentage by which obtained results differ from the real population value.

-It is calculated as half the difference between the confidence interval levels:

$ME=\frac{1}{2}[CI_u-CI_l]\\\\=0.5[0.739-0.711]\\\\=0.014$

Hence, the margin of error is 0.014

-The sample proportion is mathematically half the sum of the confidence intervals:

$ME=\frac{1}{2}[CI+u-CI_l]\\\\=0.5[0.739+0.711]\\\\=0.725$

Hence, the sample proportion is 0.725
