Answer:

The vertex of the graph is (-1,0)

Step-by-step explanation:

A vertex has different definitions

It refers to the point where we have the axis of symmetry

It can also be the point at which the graph changes direction

From the graph we have here, the vertex lie on the horizontal axis

It has an ordered pair value of (-1,0)

A company can buy packages of 500 sheets of paper for $4. At that rate, how much paper can be bought for $2000? Group of answer
Alexandra [31]
Your answer is 250,000. There are two ways to do this problem.

1) Solve 500/4 to find out how many sheets of paper you get per every dollar. — Your answer is 125 sheets for $1. Then you multiply that answer by 2000, and get 250,000. Which means you get 250,000 sheets of paper for $2000.

2) You can divide 2000 by 4 & that gets you 500, you can then multiply that by 500 & you will get 250,000.

Hope this helps.

In 2009, a town's population was about 9,000 residents. In 2014, the population was about 12,500 residents. Which linear model r
jek_recluse [69]

Answer:

The linear function that discribes the size of the population in function of the t in years is p = 700t - 1,397,300

Step-by-step explanation:

A linear function is defined by a line, so in order to determine the linear function we can use the two points that were given to us to create a line equation and use that as our linear function. The points given to us were (2009; 9000) and (2014; 12500), in this case the year is our value of "x" and the size of the population is our value of "y". The first step is to find the slope of the line which is given by:

m = (y2 - y1)/(x2 - x1)

m = (12500 -9000)/(2014 - 2009) = 3500/5 = 700

Then we can use the slope and the first point to build the equation:

p - 9000 = 700*(t - 2009)

p = 700t - 1406300 + 9000

p = 700t - 1397300

Step-by-step explanation:

i'm guessing u must be from UK.... in the US "standard form" is known as "Scientific Notation"

Write 3.25 x 10^4 as an ordinary number: 32 500

Write 6.04 x 10^-3 as an ordinary number:  0.00604

Write 2 400 000 in standard form  : 2.4 x 10^6

Write 0.00147 in standard form: 1.47 X 10^-3
