Answer:

Domain is -3

Step-by-step explanation:

Given that coordinate of a graph is (-3, -2)

We have to find out the domain.

We know that if A and B are two sets, a mapping from A to B is the subset of cartesian product AxB.

Domain is the set of values of A which have images in B.

Use the above definition.

We have A = {-3,...} and B = {-2,....}

The mapping is from -3 to -2

Hence domain is -3

ololo11 [35]

To figure this out first make the 4 4/9 into a improper fraction making it 40/9 and then multiply 2/7 x 40/9 then make is a mixed fraction :) hope this helped.

At 11:00 a.m., John started driving along a highway at constant speed of 50 miles per hour. A quarter of an hour later, Jimmy st

SVETLANKA909090 [29]

Answer:

12:05 pm

Step-by-step explanation:

Let z be the number of hours, from 11:00 am, when Jimmy would catch up with John. The time that Jimmy will have to drive to catch up with John is z - 1/4 as he started a quarter of an hour late. When Jimmy would catch up with John, they would have traveled the same distance. Hence

50 z = 65 (z - 1/4)

Solve for t

50z = 65z - 65/4

z = 65/60 = 1.083 hours = 1 hour and 5 minutes

Jim will catch up with John at

11:00 am + 1 hour 5 minutes = 12:05 pm

You can model the population of a certain city between 1955-2000 by the radical function

OverLord2011 [107]

Complete Question:

You can model the population of a certain city between 1955-2000 by the radical function

P(x) = 55,000 sqrt x-1945

Using this model, in which year was the population of that city 275,000?

Answer:

In 1970 population of that city is 275,000

Solution:

Given that,

You can model the population of a certain city between 1955-2000 by the radical function :

$P(x) = 55000\sqrt{x - 1945}$

To find: year in which was the population of that city 275,000

Therefore,

x = ?

P(x) = 275000

Thus we get,

$275000 = 55000\sqrt{x - 1945}\\\\Divide\ both\ sides\ by\ 55000\\\\\frac{275000}{55000} = \sqrt{x-1945}\\\\5 = \sqrt{x - 1945}\\\\Take\ square\ on\ both\ sides\\\\25 = x - 1945\\\\x = 1945 + 25\\\\x = 1970$

Thus, in 1970 population of that city is 275,000

Write an equation and state the slope for the line that passes through (9,22) and (15,36).

Andreas93 [3]

Answer:

Slope = 2.3 or 2

Step-by-step explanation:

First, to find the slope of the given coordinates (9,22) and (15,36), we must establish what will be our starting and endpoint.

Let's have (9,22) be our starting point.

And (15,36) be our endpoint.

First, what is the change in x?

The change in x is 6, because 9 + 6 = 15. (Δx = 6)

Second, what is the change in y?

The change in y is 14, because 22 + 14 = 36. (Δy = 14)

Now we can find the slope by dividing the change in y over the change in x or Δy/Δx:

$\frac{14}{6}$ = 2.3 or 2
