What is the factorization??

Mathematics
1 answer:
azamat3 years ago
7 0

We first find the zeros of the function , by seeing at the graph

the zeros of the function are those points at which the graph wither crosses or touches the x axis

So looking at the graph we can see that the zeros of the function are

x=-5 and x=-1

So the factors should be

(x-(-5)) and (x-(-1))

or

(x+5) and (x+1)

So the factorization will be given as

(x+5)(x+1)

How to solve<br> ?? I need help guys please anyone just help
statuscvo [17]
Bill's original ratio is like this...
6 to 10

You need to solve for this...
x to 15

You have to multiply both sides of the original ratio by 15...
6 times 15 = 90
10 times 15 = 150

Your new ratio is 90 to 150
Which reduces to 3 to 5

Yout new ratio is 3 to 5

Suppose that poaching reduces the population of an endangered animal by
Sedbober [7]

Answer:

38.26 years.

Step-by-step explanation:  

We have been given that the population of an endangered animal by  reduces 8​% per year. the current population of the animal is  1700. When the population of this animal falls below  70​, its extinction is inevitable.  

Let us write the model for population of this animal (y) after x years.

Since we know that an exponential decay function is in form: y=a*(1-r)^x, where,

a= Initial value.

r = Rate in decimal form.

Let us convert our given rate in decimal form.

8\%=\frac{8}{100}=0.08

Upon substituting a= 1700 and r = 0.08 in exponential function, we will get the model of animal population as:

y=1700*(1-0.08)^x

y=1700*(0.92)^x

Let us find, when the animal population will face extinction by substituting y=70 in our function.

70=1700*(0.92)^x  

\frac{70}{1700}=\frac{1700*(0.92)^x}{1700}

0.0411764705882353=0.92^x  

Let us take natural log of both sides of our equation.

ln(0.0411764705882353)=ln(0.92^x)

ln(0.0411764705882353)=x*ln(0.92)

-3.1898882879949483163=x*-0.0833816089390511

x=\frac{-3.1898882879949483163}{-0.0833816089390511}

x=38.2564971890460849445284\approx 38.26

Therefore, the population of the animal will face extinction after 38.26 years.

Usimov [2.4K]

Answer:

3% = 0.03

30% = 0.3

25% = 0.25

80% = 0.8

8% = 0.08

12% = 0.12

67% = 0.67

17.5% = 0.175
