Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Find the intercepts
<u>The y-intercept</u> is the value of y when the value of x is equal to zero
so
For x=0 -----> 
The y-intercept is the point (0,-1)
<u>The x-intercept </u>is the value of x when the value of y is equal to zero
so
For y=0 ----->
----->
The x-intercept is the point (-1,0)
<em>Find the domain</em>
we know that
The radicand must be positive
so


All real numbers greater than or equal to -1
The range is all real numbers less than or equal to -1
using a graphing tool
see the attached figure
Answer:
You have found 24 nickels.
Step-by-step explanation:
Let N be the number of nickles, D be the number of dimes and Q be the number of quarters. The number of coins and their face values are given by the following expressions, respectively:

As of now we have three variables and two expressions, the final expression needed to solve the linear system is given by the amount offered by the coin dealer:

Solving the linear system:

You have found 24 nickels.
Answer:
It is the representative of the whole group
Step-by-step explanation:
Mean is the only one out of mode, median , mean or range that actually implies all the values in the data.
Hope this helps.
Good Luck
I think it’s 13 not sure tho(put a degree symbol on 13)
Answer:
Step-by-step explanation:
Given that in 1987, the population of country A was estimated at 87 million people, with an annual growth rate of 3.5%
Thus the equation for population for country A would be

The 1987 population of country B was estimated at 243 million with an annual growth rate of 0.6%.
So equation for population for country B would be
where t = time in years and P in millions
a) P(A) = 2*87 when

Take log and solve
ln 2 = 0.005 t
t = 138.63
Thus after 138 years population will double for A
b) P(A) = P(B) when

Approximately after 35.5 years the populations of both countries would be equal.
