Step-by-step explanation:
Answer:
The value of a = - 1 , And b = 
Step-by-step explanation:
Given as :
Function f(x) = 
And f(f(1)) = 0 And f(2) = - 3
Now For , x = 2 , y = - 3
I.e f(2) = 
or, - 3 =
I.e 2 + a = - 6 - 3b
Or, a + 3b = - 8 ....... 1
Again f(f(1)) = 0
So, 
= 0
Or, 1 + a = 0
∴ a = - 1
So , put htis value of a i n eq 1 , we get value of b
So , - 1 + 3b = - 8
Or, 3b = - 7
∴ b =
Hence The value of a = - 1 , And b = Answer
Answer:
Correct answer is 30,000
Step-by-step explanation:
From multiplication :
6 * 5 = 30
Now moving to:
60 * 500
Number of ending zeros in both values = 3 ; (000)
This 3 0's will be placed at the end of the result of multiplying 6 by 5
Hence,
6 * 5 = 30
60 * 500 = 30+000 = 30,000
Hence, 60 * 500 = 30000
Step-by-step explanation:
( secA + 1)( sec A - 1)
Using the expansion
( a + b)( a - b) = a² - b²
Expand the expression
We have
sec²A + secA - secA - 1
That's
sec² A - 1
From trigonometric identities
<h3>sec²A - 1 = tan ²A</h3>
So we have the final answer as
<h3>tan²A</h3>
As proven
Hope this helps you
Answer: 27.27 seconds?
Step-by-step explanation:
25 - 16.26 = 8.74
19/8.74 = 2.2 (Rounded up)
