see explanation
Step-by-step explanation:
If (x + 1) is a factor then f(- 1) = 0
f(- 1) = 19
+ 18(- 1) - 1 = 19 - 18 - 1 = 0
Thus (x + 1) is a factor of f(x)
[67.9 %, 82.1 %] is the 95% confidence interval for the proportion of test-takers answering the question correctly. So we have [67.9 %, 82.1 %] In a random sample of 144 test-takers with 75% answered the question correctly. So the answer in this question is [67.9 %, 82.1 %].
Here’s the answer w explanation :)
<span> The least perimeter occurs when rectangle is square.
So you can start by taking square root of area; </span>√32
So each side is √32 and there are 4 sides
Hence least perimeter is 4√32 = 16√2 ≈ 22.627.
The answer is 1.
<span>1 is the number raised to both the first power and the second power equal 1.
</span>Any number raised to the second power means it is multiplied by itself 2 times and also any nonzero number that is raised to the power of zero is also equal to 1, x⁰=1 for example 2⁰ = 1, 4⁰ =1
