Jericho is a botanist and is researching about a particular species of plant. He found that the number of plants in his testing
yarga [219]

Answer:

Step-by-step explanation:

Let initial number of plants =100

Increase I year                        60

Number after 1 year               160

Increase IIyear 60%                96

Number after II year               256

Increase in III year 60%           153.6

and so on

In general if t is number of years and N number of plants after n years

the expression would be

N(t)=N_{0} (1.06)^t

In other words, the expressions wouldbe the same as amount after t years of compound interest.

If cos8x = 13/36 find the value of cos4x.​
Elina [12.6K]

The value of cos 4x from the given identity is 0.999

<h3>Trigonometry identity</h3>

Given the cosine identity

cos8x = 13/36

Determine the value of x

8x = arccos(13/36)
8x = 0.36111

x = 0.36111/8
x = 0.04514

Determine the value of cos4x

cos4x = cos4(0.04514)

cos4(0.04514) = 0.999

Hence the value of cos 4x from the given identity is 0.999

A single die is rolled twice. Find the probability of rolling an oddnumber the first time and a number greater than 2 the second
harkovskaia [24]

Answer:

1/3.

Step-by-step explanation:

The 2 events are independent so we multiply the 2 probabilities.

Prob(rolling an odd number) = 3/6 = 1/2.

Prob(rolling a number greater than 2) = 4/6 = 2/3.

The required probability = 1/2 * 2/3

= 2/6

= 1/3.
