Answer:
The right answer is:
Option OB: f(1) = -9
Common difference: 7
Step-by-step explanation:
Given sequence is:
-9, -2, 5, 12,...
Here the first number is f(1)
Common Difference:
Common difference is the difference between consecutive terms of an arithmetic sequence. It is denoted by d.
In the given sequence,
f(1) = -9
f(2) = -2
f(3) = 5
Hence,
The right answer is:
Option OB: f(1) = -9
Common difference: 7
T ∫ 1/√(1 - x²) dx = arcsin(x)
<span> ∫ 1/√(1 - x²/a) dx = √a arcsin(x/√a) </span>
<span>So pull a factor of 5 out of the square root to get </span>
<span>1/5 ∫ 1/√(1 - 16 x²/25) dx </span>
<span>= 1/4 arcsin(4 x/5)</span>
Answer:
1. 110 degrees.
2. 276 students.
Step-by-step explanation:
1. Converting the ratios to fractions:
3 + 4 + 11 = 18 so the largest angle is 11/18 of 180 degrees.
Answer is 180 * 11/ 18 = 110 degrees.
2. That would be 460 * 36 / 60
= 276 students.
16 is $32
idk the others.... sorry.
