Answer:
Option d
Step-by-step explanation:
Other options are not eligible because
a) Integers are not irrational
b)Whole numbers start from 0 and consists positive integers only.But integers consist negative integers also.
c)Natural number consists of positive integers only.
If the question had been asked as some integers are also, then options b) and c) could have been written . But in this case , it is asked every integer is also.
Thank you!

From the given information, the first term of the sequence is
The common ratio of the sequence is
The explicit formula for a geometric sequence is :
To find the third term, we put n=3 to get:
This simplifies to:
Answer:
1
Step-by-step explanation:
you simply divide 154 by 9, get around 17.1. 17 is the closest whole number answer, so 17*9 is 153.
do 154-153, you get 1.
not the best explaination but i hope it helps.
Hello :)
Answer: x=11
Measure angel BAD= 122
Explanation:
To find X you have to make an equation
10x-49=5x+6
And then you solve for x
To find the angel measure of BAD, you have to add bac and cab to get bad
Bac= 10(11)-49 which equals 61
Cab= 5(11)+6=61
61+61= 122
Which is the measure of BAD
I hope this helps and have a wonderful rest of your night
Answer:
The answer is below
Step-by-step explanation:
We need to prove that:
(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.
Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.
Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A
