In a field study, a scientist was predicting the insect population. The initial amount of insects in the area was 15,000. The sc
Mila [183]

The estimated population, if the rate is a growth rate is 34696 populations

The estimated population, if the rate is a decline rate is 5657 populations

<h3> Exponential functions</h3>

The standard exponential equation is expressed as y = ab^x

where;

  • a is the intercept
  • b is the growth rate
  • x is the time taken

If the initial population is 15,000 with a rate of 15%, then;

a) If the rate is a growth rate, the estimated population will be expressed as;

y = 15000(1+0.15)^{6}\\y=15000(1.15)^6\\y = 15000(2.313)\\y \approx 34,696

The estimated population, if the rate is a decline rate is 34696 populations

b) If the rate is a decline rate, the estimated population will be expressed as;

y = 15000(1-0.15)^{6}\\y=15000(0.85)^6\\y = 15000(0.37715)\\y \approx 5,657

The estimated population, if the rate is a decline rate is 5657 populations

Solve for x in the equation x squared + 2 x + 1 = 17.
Whitepunk [10]

Answer:

x = negative 1 plus-or-minus StartRoot 17 EndRoot

Step-by-step explanation:

Given:

x^2+2x+1=17

We need to solve for x.

x^2+2x+1=17 \ \ \ \ equation\ 1

First we will solve L.H.S

Factorizing the equation we get;

x^2+2x+1\\=x^2+x+x+1\\=x(x+1)+1(x+1)\\=(x+1)(x+1)\\=(x+1)^2

Now Things which are equal to the same thing are also equal to one another. Since

x^2+2x+1=17

x^2+2x+1=(x+1)^2

then, according to the law of transitivity,

(x+1)^2=17

Now, applying the Square Root Principle we get:

\sqrt{(x+1)^2} =\sqrt{17}

Now Square root and square gets cancelled.

x+1=\sqrt{17} \\x=-1+\sqrt{17}

Since a square root has two values, one positive and the other negative.

x=-1\±\sqrt{17}

Hence  Final Answer is x=-1\±\sqrt{17}.
