A fish is swimming at a constant rate toward the ocean floor. The equation

y = -7x -3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

Which statement best describes the depth of this fish, given this equation? (DOK 3)

A
From a starting position of 3 meters below sea level, the fish is going down( descending) 7 meters per second

B
From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second

C
From a starting position of 7 meters below sea level, the fish is descending 3 meters per second

D
From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second

Answers

Answer 1

Answer:

Step-by-step explanation: the -7x represents the 7 meters the fish is going down every second and the -3 would be the fish starting at 3 meter below sea level

Answer:

31 square inches

Step-by-step explanation:

You can divide the shape into pieces several ways. The total area will be the sum of the areas of the pieces.

If we draw a horizontal line across the figure 2 inches up from the bottom, the figure is divided into a triangle and two rectangles.

The triangle has a base of 8 -3-2 = 3 inches, and a height of 4 -2 = 2 inches. Its area is ...

A = (1/2)(3 in)(2 in) = 3 in²

The rectangle below the line has a base of 8 inches and a height of 2 inches. Its area is ...

A = bh = (8 in)(2 in) = 16 in²

The rectangle above the line has a base of 3 inches and a height of 4 inches. Its area is ...

A = bh = (3 in)(4 in) = 12 in²

Then the total area of the figure is ...

(3 + 16 + 12) in² = 31 in² . . . . the area of the figure

[tex]x = -7[/tex]

Find h(x)

Substitute -7 for x

[tex]h(x) = |2*-7| - 4[/tex]

We need to find how many minutes would it take him to run 1500 meters.

ATQ,

600 m = 5 min

1 m = (5/600) min

Which of these expressions is equivalent to log

?
O A. log (12) - log (5)
O B. 12. log (5)
O C. log (12) + log (5)
O D. log (12) log (5)

Answers

The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).

What is logarithm and some of its useful properties?

When you raise a number with an exponent, there comes a result.

Lets say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

b = \log_a(c)

'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'

We have given an expression as ;

log (12/5)

We know that

[tex]log_a(b) - \log_a(c) = \log_a(\frac{b}{c})[/tex]

So,

log (12/5) = log (12) - log (5)

Thus, the correct option is A. log (12) - log (5)

The expressions that is equivalent to log (12/5) would be A. log (12) - log (5).

A table of values of a linear function is shown below. Find the output when the input is n . Type your answer in the space provided.
input: 1 2 3 4 n
output: -10 -13 -16 -19 (Blank)

Answers

Answer:

5; -22

Step-by-step explanation:

A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional.

Given the following data;

Input: 1 2 3 4 n

Output: -10 -13 -16 -19

For an input variable of 1, 2, 3, 4; the output variable is -10, -13, -16, -19 respectively.

To find the value of n;

We can deduce that the input is increasing by a value of 1.

Thus, n = 4 + 1 = 5

For the output;

We can deduce that the output is increasing by a value of -3.

Thus, the next output = -19 + (-3) = -22

5; -22

A town plans to clear a patch of forest to make a road wider. What possible changes should the town take into account? Society during the middle ages was organized into a feudal system, which consisted of small communitiescongregated around a central "Lord." The owner of all of the land in a country was ultimately the king, but because the king couldneither protect nor rule all of his land himself, he divided it up into segments called "fiefs" and awarded fiefs to important nobles,typically barons or bishops, in exchange for their contributions of soldiers and/or money to the king's armies. The Lords lived in alarge house or a castle called the manor. People would gather at the manor for celebrations, or for protection, if necessary.Immediately around the manor was the village, which included the church. Farms, which supplied food to the Lord and to thevillagers, were in the outlying areas.About 90% of the people that lived under the feudal system in the middle ages were peasants, usually called "serfs." The Lordsprotected the peasants, and in return the peasants worked for the Lords. Though some peasants were free and practiced trades likecarpentry, baking, and blacksmithing, most were little more than slaves. They worked long, hard days, six days a week for not muchmore than subsistence.Women worked hard during this period too, and not only at the household tasks that you would expect them to do, like cooking,baking bread, sewing, weaving and spinning. They also hunted for food, fought in battles, and worked as blacksmiths, merchants andapothecaries, midwives, fieldworkers, writers, musicians, dancers or painters. Other women became nuns. Some women werebelieved to be witches. A famous woman from the middle ages is Joan of Arc, the daughter of a French peasant, who claimed to hearvoices instructing her to protect France against the English invasion. Dressed in armor, she led a victorious troop of soldiers againstthe English in the fifteenth century. But the Middle Ages was rife with ignorance and superstition, and even after her service to hercountry, Joan of Arc was burned as a witch.1. What was the benefit of the feudal system to the king?
