The answer is 15
these chords are congruent because the radius of the circle are perpendicular to the them
so we can find EF by making an equation:

so EF is = 3(15)+5=50
good luck
Answer:

Step-by-step explanation:


Step-by-step explanation:
h(x)=-x-4
but h(x)=4
4=-x-4
x=-4-4
x=-8
For this case, the first thing we are going to do is define the following equation:
N = (number of cups) / (capacity of a quart container)
Where,
N: number of containers.
We have then:
N = (240) / (1/4)
N = 960 containers
Answer:
kat will need:
N = 960 containers
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.
