Answer:
Coordinates of other end point L = ( -19, 13 )
Explanation:
The mid point of the coordinates (a,b) and (c,d) is given by 
Here we have (a,b) = (1,-7) and
= (-9,3) , we need to find (c,d).

So coordinates of other end point L = ( -19, 13 )
<span>4(a^2 + 2b) - 2b
= 4a^2 + 8b - 2b
=</span> 4a^2 + 6b
Answer:
y = 0
Step-by-step explanation:
Since there is no indication of a shift in the graph of f(x) = 3cos(-0.25x), then the midline must be the normal midline for a cosine or sine function which is: y = 0.
Equation for Liz:
L = 8n
Equation for Andy:
A = 8n + 35
Step-by-step explanation:
Let the no. of necklace be 'n'
Cost per necklace= $8
Equation for Liz:
L = 8n
Because Liz sells only necklace for $8 each
Equation for Andy:
A = 8n + 35
Because Andy sells each necklace for $8 and she sold the bracelets for $35
Answer:

Step-by-step explanation:
The general formula for exponential decay given a half-life
is
where N(t) is the amount at time t,
is the initial amount (at time t=0), and
is the half life of the substance.
The half life of carbon-14, is approximately 5,730 years.
= 5730 years
= 6 milligrams
Therefore:
Amount of carbon-14 remaining in the bone fragment after t years is:
