By applying the formula of trigonometric function the right hand side will
be equal to right hand side which is 1-
/
=cos2x.
Given: 1-/=cos2x.
Taking right hand side first which is cos2x.
We know that cos2x=
Now we will solve the left hand side of the equation give which is
1-/
=1-
/1+
[secant square x minus tangent square x is equal to 1]
By putting both values left hand side and right hand side we will find our solution which is :
1-tan^{2}x/1+tan^{2}x=1-/1+.
Hence proved

Answer: A proportion is simply a statement that two ratios are equal.
Example: 2:6 = 1:3
To get that you do this: 2:6 ÷ 2:2 = 1:3
-----------------------------------------------------------
Example 2: 5:10 = 1:2
To get that you do this: 5:10 ÷ 2:2 = 1:2
Checking for each option
Option A:
Substitute w = 10 and check if we'd get 900 as the answer
Option B:
Substitute w = 10 and check if we'd get 900 as the answer
Option C:
Substitute w = 10 and check if we'd get 900 as the answer
Option D:
Substitue w = 10 and check if we'd get 900 as the answer
Answer: Option B
#5 is 5 days
40×5=200
200+150=250
20×5=100
100+150=250
Answer:
3200
Step-by-step explanation:
Given that:
The initial population of birds 
= 100
The time duration t = 5 years
Growth rate (r) = (Birth - Death) rate
= 2 - 1
= 1 / year
∴
using the discrete-time form:
