The third term of an arithmetic sequence is 21, and the eighth term is 56. The first term is _____.

Answers

Term for an AP =  a  + (n-1)d.

The third term =  a + (3 -1)d = a + 2d = 21

The eight term =   a  + (8 - 1)d = a + 7d = 56


a + 2d = 21
-
a + 7d = 56
__________ 
0  -5d  =  -35
 
-5d = -35

d = -35/-5

d = 7

Substitute d = 7 in a + 2d = 21

a + 2d = 21
a + 2*7 = 21
a + 14 = 21
a = 21 - 14
a = 7

The first term, a = 7.
 

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!how do the liver and pancreas help complete chemical digestion?

Answers

The pancreas produces enzymes that help digest proteins, fats, and carbohydrates. It also makes a substance that neutralizes stomach acid. The liver produces bile, which helps the body absorb fat. Bile is stored in the gallbladder until it is needed. These enzymes and bile travel through special channels (called ducts) directly into the small intestine, where they help to break down food
he pancreas produces the proteases trypsin and trypsinogen which digest proteins into smaller peptide units while carboxypeptidase can digest peptides to amino acids though it's not the main enzyme for this task.

Lipase digests triglyceride fats into their constituent fatty acids and glycerol while amylase breaks down starch into two or three glucose units (maltose and maltotriose) plus small branched glucose units (maltidextrins). 

The panceras also secretes bicarbonate to neutralise the acid contents coming from the stomach and create an alkaline environment which enables pancreatic and small intestine enzymes to work at their optimal speed. 

The liver contributes no digestive enzymes just bile which emulsifies the fats, breaks them up to smaller drops, so as to increase the surface area on which the enzymes can act thus speeding up their digestion.

Which experiment describes a binomial experiment?Spin a spinner with sections labeled A, B, and C, 6 times and record the result each time.

Roll one die 10 times and record each time you roll and prime number.

Roll 2 number cubes until rolling a sum of 8 and record how many trials you completed.

Answers

Answer: the last option.
A binomial experiment is an experiment with only two possible outcomes.

In the first option, there is three possible outcomes (i.e. A, B, C)
In the second option, there is four poissible outcomes (i.e. ace, king, queen, jack)
The third option has six possible outcomes (i.e. six faces of a die)
In the last option, there are two possible outcomes (i.e. '2 number cubes')

A _____ is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

Answers

A function is a rule that assigns each vale of the independent variable to exactly one vale of the dependent variable.

The missing word is the function.

Point to remember:

The definition says that two values of x(independent variable ) may correspond to one value of y(dependent variable) but the vice versa is not true( means two values of y(dependent variable ) does not correspond to one value of x(independent variable) ). This explanation is very powerful tool to check that whether a relation is a function or not.

Answer:Function


A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

Which of the following is an equivalent form of the compound inequality -22 > -5x - 7 -3? A)-5x - 7 < -22 and -5x - 7 -3
B)-5x - 7 < -22 and -5x - 7 -3
C)-5x - 7 > -22 and -5x - 7 -3
D)-5x > -22 and -7 -3

Answers

the equivalent form of the given inequality is obtained by dividing the inequality into two parts. In this case, we are given -22 > -5x - 7 > -3. The two parts are -22 > -5x - 7 and -5x - 7 > -3. The choice that reflects these parts is A)-5x - 7 < -22 and -5x - 7 -3
