Temka [501]

Answer:

Every day, there is a 49% percent the locust population.

Step-by-step explanation:

To find the daily percent change of the locust population, we just need to find N(t) for t = 0, N(t) for t = 1, then subtract the second by the first, and then divide the result by the first:

N(t) = 8950*(0.7)^2t

N(0) = 8950*(0.7)^0 = 8950*1 = 8950

N(1) = 8950*(0.7)^2 = 8950*0.49 = 4385.5

Change = N(1) - N(0) = 4564.5

Percent change = Change/N(0) = 4564.5/8950 = 0.51 = 51%

As after one day, the population decrease by 51% of the inicial population, the remaining population is 100% - 51% = 49%, so we can write:

Every day, there is a 49% percent of the locust population.

The lengths of the sides of a triangle are in ratio 5 : 7 : 9. The middle-in-length side is 35 cm. Find the perimeter of the tri

ipn [44]

Answer:

The perimeter of the triangle is 105 cm.

Step-by-step explanation:

The ratio of sides of a triangle is $5:7:9$ .

The length of middle side is 35 cm.

Let first side of the tringle is $x$ , length of third side is $y$ . middle side is of 35 cm.

So, the ratio of length of sides can be written as,

$x:35:y=5:7:9$

Compare the ratio to get the value of $x$ and $y$ .

$x:35:y=25:35:45\\x=25\\y=45$

Now, the sides of the triangle are 25 cm, 35 cm and 45 cm.

Thus, the perimeter of the triangle will be the sum of all sides and can be calculated as,

$p=25+35+45\\p=105$

Therefore, the perimeter of the triangle is 105 cm.

Which function is undefined when theta=pi/2 radians?

Verizon [17]

We know that tanθ = sinθ/cosθ

For a number to be undefined, the denominator must equal to 0. At π/2, the cosθ value is 0 and sinθ is 1. Hence, tan(π/2) is undefined.

Hope I helped :)
