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

Which is true about constructing a bisector of the angle?
IgorLugansk [536]
When you bisect something you are cutting it in half. so in the image above when you cut it in half you would be forming 2 angles. Your answer is D. because when you cut in half you are going to have equal sides. Its like taking an 75 degrees and bisecting it and each of the new angles would be 37.5.

Is it true w is the set of (s,w,n,t,c)
umka21 [38]

Answer:

{w} is the SUBSET of   {s,w,n,t,c}

Step-by-step explanation:

SUBSET: Any set  P is called a SUBSET of a set Q is ALL ELEMENTS of P are in the set Q.

i.e P ⊂ Q

Here, the given set  Q  =  {s,w,n,t,c}

Also, set P = {w}

Now,as the element w of set P is also an element of set Q.

⇒ P is the SUBSET of  Q

⇒ P ⊂ Q

⇒  {w} ⊂  {s,w,n,t,c}

Hence,   {w} is the SUBSET of   {s,w,n,t,c}.
