hey!!!

Here's your answer;

The word trigonometry is derived from two Greek words trigon and metron. Trigono means triangle and metron means measurement. Therefore in literal terms trigonometry is the measurement of the angles of a triangle. The application of trigonometry is very vast.It is used in measuring eight and distance, surveys,Map making, astronomy, engineering etc.

The longest side,which is the opposite side of right angle is the hypotenuse.There are two other side's,the opposite and the adjacent.The naming of these sides depends upon which angle is involved.The opposite is the side opposite the angle involved and it is called the perpendicular.

The adjacent is the side next to the angle involved(but not the hypotenuse) and it is called base.

The area of mathematics relating to the study of trigonometric function in relation to measurement in triangles is known as trigonometry...
Or
Trigonometry refers to the measurement of triangles.

If N is the population of the colony and t is the time in days, express N as a function of t. Consider Upper N 0 is the origina

lesya [120]

Answer:

(a) $N(t)=Noe^{kt}$

(b)5,832 Mosquitoes

Step-by-step explanation:

(a)Given an original amount $N_o$ at t=0. The population of the colony with a growth rate $k \neq 0$ , where k is a constant is given as:

$N(t)=Noe^{kt}$

(b)If $N_o=1000$ and the population after 1 day, N(1)=1800

Then, from our model:

N(1)=1800

$1800=1000e^{k}\\$Divide both sides by 1000\\e^{k}=1.8\\$Take the natural logarithm of both sides\\k=ln(1.8)$

Therefore, our model is:

$N(t)=1000e^{t*ln(1.8)}\\N(t)=1000\cdot1.8^t$

In 3 days time

$N(3)=1000\cdot1.8^3=5832$

The population of mosquitoes in 3 days time will be approximately 5832.

(c)If the population N(t)=20,000,we want to determine how many days it takes to attain that value.

From our model

$N(t)=1000\cdot1.8^t\\20000=1000\cdot1.8^t\\$Divide both sides by 1000\\20=1.8^t\\$Convert to logarithm form\\Log_{1.8}20=t\\\frac{Log 20}{Log 1.8}=t\\ t=5.097\approx 5\; days$

In approximately 5 days, the population of mosquitoes will be 20,000.

Compare & Contrast: What is different about complementary and supplementary angles? What is the same?

kirza4 [7]

Complementary: When two angles add up to 90 degrees

Supplementary: When two angles add up to 180 degrees

Similarities are both involve two angles, the difference is the total degrees they add up to.

6+y is greater than or equal to 9. what is y

Rufina [12.5K]

6 + y ≥ 9

We are essentially trying to get y by itself, so that we could solve for y

So, subtract 6 from both sides.

y ≥ 9 - 6

Simplify.

y ≥ 3
