The required length is the circumference of the circle.
Length = πd = 4.2π
Answer:
Step-by-step explanation:
yes.
x/y is a rational number
because xxby y is irrational that why x/y is rational number
Answer:
∠CAB = 48.81 degree.
Step-by-step explanation:
Let us consider, ∠CAB =
From figure,
Question 1
You can see that each term is obtained from the previous one by subtracting 8. Starting from 30, we subtract 8 to get 22. Then, we subtract 8 to get 14, and we subtract 8 to get 6.
So, the next three terms will be given by subtracting 8 again and again:
Correct answer: D
Question 2
The sequence starts with 4, and so option is surely wrong. Every next term is given by doubling the previous one: starting with 4, we double it to get 8; we double it it get 16, and finally we double it to get 32.
Correct answer: A
Question 3
In order to find the first four terms of the sequence, we have to plug the values in the equation: we have
Correct answer: B
Answer:
x=-2
Step-by-step explanation:
To solve this, let's set the two exponents so that they have the same base. We know that 9 is 3², so we can rewrite the left side as (3²)^(x-8), which simplifies to 3^(2x-16). Now, we have 3^(2x-16) = 3^(4x-12). Since the bases are equal, the exponents are also equal. Therefore, 2x-16 = 4x-12. When we solve, we get -2x = 4, so x=-2. Hope this helps!
