Answer:

a=3,b=7,c=-20

Step-by-step explanation:

we are given equation as

3x^2=20-7x

Firstly, we will move all terms on left side

Subtract both sides by 20

3x^2-20=20-7x-20

3x^2-20=-7x

Add both sides by 7x

3x^2-20+7x=-7x+7x

3x^2-20+7x=0

3x^2+7x-20=0

now, we can compare it with quadratic equation

ax^2+bx+c=0

and we get

a=3,b=7,c=-20

a rancher is selling off 7% of her ranch each year. If she owns 2000 square miles, in about how many years will she own only 600
Nutka1998 [239]
This is an exponential decay function, or it can also be viewed as a geometric sequence, either way, it can be expressed in this circumstance as:

f=ir^t, f=final amount, i=initial amount, r=common ratio or rate, t=times ratio is applied or time.

In this case i=2000 and r=(100-7)/100=0.93 so

f=2000(0.93^t)

We are asked to find when f=600 so:

600=2000(0.93^t)  divide both sides by 2000

0.3=0.93^t, take the natural log of both sides

ln0.3=t*ln0.93  divide both sides by ln0.93

(ln0.3)/(ln0.93)=t

t≈16.59

So in about 16.5 years she will own only 600 square miles.  (round as appropriate for your answer)

Where is the vertex of y=3(x-26)^2+14?
Morgarella [4.7K]
The vertex is (26,14)

Because it’s written in vertex form which y=a(x-h)^2 + k. H is the x for the vertex And h is changed to it’s opposite. So since 26 is negative it would actually be positive 26. While k ls the y of the vertex which is 14 in our case
