FIND THE LOWERCASE L IN ALL THE UPPERCASE I's

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti

No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

$m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1$

For the slope of ln:

$m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\$

For the slope of mn:

$m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\$

If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

$m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2$

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

Drag one molecule and one chemical property to each bin. If one property can apply to more than one functional group, choose the

BartSMP [9]

There are different kinds of functional group. The answer to the functional group, is below.

(OH) Alcohol is one of the most polar and may act as a weak acid
(COOH) Carboxylic acid serves as the acid.
(C=O) Aldehyde: can be an isomer of a chemical ketone
(S-H) Thiol usually transform to a disulfide bond
(NH2) Amine serves to be the base of chemical compounds
(PO4) Organic phosphate carries a negatively charged atom.

<h3>What is functional group ?</h3>

A functional group in organic chemistry is known to be a composition of atoms that is found inside a molecules that often bind together to react in certain ways.

The Examples of functional groups are the group hydroxyl, ketone, amine, and others.

A story with multiple narrators will usually have a(n) ____________ plot.

Soloha48 [4]

Stories could either have a single or multiple narrator(s). Hence, stories having multiple narrators would usually have a non-linear plot.

Multiple narrators in a story means that characters in the story are numerous, hence, acts and scenes would have to be passed on to these characters from time to time.

As for single narrator, this is not the case as the number of actors are very limited.

Hence, because multiple narrators often hinders a story to be chronologically ordered, then it would result in a non-linear plot.

An unsaturated solution is formed when 80. Grams of a salt is dissolved in 100. Grams of water at 40. °c. This salt could be.

Alinara [238K]

${answer}$

An unsaturated solution is formed when 80. Grams of a salt is dissolved in 100. Grams of water at 40. °c. This salt could be.

Solubility is the maximum amount of soluble solid that can be dissolved in a 100-gram of water at a specific temperature. The solubility of a compound is directly proportional to the temperature which means that more solids can be dissolved at a higher temperature. Moreover, a solution which has a concentration below its solubility is an unsaturated solution. When both concentration and solubility are the same, then the solution is saturated. Lastly, when the concentration of a solution is higher than the solubility at a specific temperature, then the solution is called supersaturated.
