Answer:

The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].

Step-by-step explanation:

The point-slope form of the equation of the line is represented by the following expression:

[tex]y - y_{o} = m\cdot (t-t_{o})[/tex] (1)

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]y[/tex] - Height below the top of the well, measured in feet.

[tex]t_{o}[/tex], [tex]y_{o}[/tex] - Known information of the well, measured in seconds and feet, respectively.

[tex]m[/tex] - Slope, measured in feet per second.

If we know that [tex](t_{o},y_{o}) = \left( 1\,s, -1\,ft\right)[/tex] and [tex]m = 4\,\frac{ft}{s}[/tex], then the equation in point-slope form of the line is:

[tex]y + 1 = 4\cdot (t-1)[/tex]

The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].

Answer:

A. y = 2x - 3

Explaination:

It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.

Answer:

A

Step-by-step explanation:

X intercept : (3/2 , 0)

Y intercept : (0 , -3)

Slope: m=2

Answer:

A

Step-by-step explanation:

Answer:

y= -3x-2

Step-by-step explanation:

1. Take any two points from the line

• (1, -5) (-2, 4)

2. Use the equation: y2-y1 / x2-x1 to find the slope

4- (-5) / -2-1

= 9/-3

= slope is -3

3. Find the y intercept

y= -2

Answer:

The function shown on the graph has a smaller rate of change but a higher starting point.

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

Start at the y-intercept which is 1, and go down however many times it would take, for you to go across and get to a point. Basically to find the slope is rise over run. In this case you would "rise" -3 and run 1. I haven't done this in awhile. If its wrong, I apologize. Have a good night.

we are told that the ratio of milk to flour is 1.5cups to 3 cups

in other words, to prepare cake we need 1.5 cup of milk and 3 cups of flour

if we use 5 cups of flour we can balance up using the relation below

      1.5cups of milk require 3 cups of flour

      x cups of milk require 5 cups of flour

cross multiply we have

x=1.5*5/3

x=7.5/3

x=2.5cup of milk

Answer:

i feel this is an incomplete picture

Step-by-step explanation:

Answer:

Step-by-step explanation:

A relative maximum (or minimum) point is a point that is higher (or lower) than all of the points surrounding it.

This graph has a relative minimum point where A(t)=-12A(t)=−12A, left parenthesis, t, right parenthesis, equals, minus, 12, which means that Keith's lowest altitude was \textit{12}12start text, 12, end text meters below the ground.

A positive (or negative) interval is a domain interval over which the function values are all positive (or negative).

Since A(t)>0A(t)>0A, left parenthesis, t, right parenthesis, is greater than, 0 over the interval [6.5,10][6.5,10]open bracket, 6, point, 5, comma, 10, close bracket, this is a positive interval. This means that between the \textit{6.5}6.5start text, 6, point, 5, end text- and \textit{10}10start text, 10, end text-minute marks, Keith was above the ground.

An increasing (or decreasing) interval is a domain interval over which the function values increase (or decrease) as the input variable increases.

In this graph, the interval, 5, point, 5, comma, 8, close bracket is an increasing interval. This means that between the   end text-minute marks, the elevator was going up.

Given:

Of the 100 people polled, 20 like playing golf.

To find:

The percentage of the people who like playing golf.

Solution:

In the poll,

Total number people = 100

Who like playing golf = 20

Now, percentage of the people who like playing golf is

[tex]Required \%=\dfrac{\text{Number of people who like playing golf}}{\text{Total number people in poll}}\times 100[/tex]

[tex]Required \%=\dfrac{20}{100}\times 100[/tex]

[tex]Required \%=20[/tex]

Therefore, 20% of the people like playing golf.

There are several constructions that can be done with the straightedge and the compass.

The statement that describes the figure Kelly is constructing is: (c) a line parallel to RS through Q

From the figure, we have the following observations

When a line is drawn from point Q through the intersection of these lines, the line would be parallel to line RS.

Hence. we can conclude that:

Kelly is constructing (c) a line parallel to RS through Q

Answer:

A and C

Step-by-step explanation:

B has a domain connected to many other ranges which makes a relationship but confuses the whole function making it incorrect.

For answer D, the x coordinates 1 and 3 both have two y coordinates. That again makes a relationship but confuses the function making that answer incorrect.

In answer A, no domain is repeated in any of the points making it a function.

In answer C, again no domains are paired with more than one range making it a function. That why A and C are the answers

Answer:

The Bimini team won a high proportion of games when scoring 40 points or more (18/20) compared with when they scored less than 40 points (11/20).

The best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The rugby squad from Bimini High School won the state title that year. A record of their wins and losses is shown, in which the relationship between wins and losses is sorted by the number of points scored. From observation, The best evidence is given when scoring 40 points or more in a game, the Bimini team won more games (18/20) than when scoring fewer than 40 points (11/20).
