Answer:
The treatment decays by half each week.
Step-by-step explanation:
The decay function is given by:

Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = decay rate
<em>t </em>= time
The decay function for one medications to treat dogs for fleas is:

Here the decay rate is:

The treatment decays by half each week.
Answer:
20300m^2
Step-by-step explanation:
first try to imagine the shape bisected into a rectangle and a triangle
to find the missing part of the triangle or the bottom side you need to subtract 70m from 140 m
140m-70m=70m this will be the base of your triangle
now you need the side
230m-60m=170
triangle formula base x height/ 2
70m x 170m=a
11900m=a
now the rectangle
base x height=a
60m x140m=a
8400m=a
finally add the two quantities together
8400m+11900m=a
20300m^2=a
Answer:
A
Step-by-step explanation:
"17 less than twice a number" is 2n - 17
"No more than 35" is
35
2n - 17
35
Hi
So first off, you don't want a negative 6/5y
So you move it to the other side to make it positive, now your equation is
24=6/5y
Now divide both sides by 6/5 to get y by itself
y=20
Hope this helps
