Answer: C
Step-by-step explanation:
1+2e^x+1=9
2e^x+1=9-1
e^x+1= 8/2
e^x+1 = 4
Here we can applicate the Ln:
ln e^x+1 = ln 4
Applicating the log property for exponent:
(x+1).ln e = ln 4
Ln e = 1, so:
x+1 = ln 4
x = ln 4-1
We have the following expression:
(2x ^ 3-12x ^ 2 + 10x-108) / x-6
Dividing the expression between x-6 we have:
quotient: 2x ^ 2 + 10
remainder: - 48
We can check the result then rewriting the expression:
2x ^ 3-12x ^ 2 + 10x-108
= (2x ^ 2 + 10) * (x-6) - 48
= (2x ^ 3 + 10x - 12 x ^ 2 - 60) - 48
= 2x ^ 3-12x ^ 2 + 10x-108
Division OK.
Answer:
The result of the division is:
quotient: 2x ^ 2 + 10
remainder: - 48
Answer:
8
Step-by-step explanation:
if you find where the line goes through 3 it will be at 8
<u>Answer:</u>
75 ft
<u>Step-by-step explanation:</u>
Here we are given a right angled triangle with a known angle of 20°, length of the hypotenuse to be 80 and we are to find the length of the base x.
For that, we can use the formula for cosine for which we need an angle and the lengths of base and hypotenuse.
![cos \alpha =\frac{base}{hypotenuse}](https://tex.z-dn.net/?f=cos%20%5Calpha%20%3D%5Cfrac%7Bbase%7D%7Bhypotenuse%7D)
So putting in the given values to get:
![cos 20=\frac{x}{80} \\\\x= cos 20*80\\\\x=75.17](https://tex.z-dn.net/?f=cos%2020%3D%5Cfrac%7Bx%7D%7B80%7D%20%5C%5C%5C%5Cx%3D%20cos%2020%2A80%5C%5C%5C%5Cx%3D75.17)
Therefore, the value of x is the closest to 75 ft.
Answer:
Yes, he would take the same decision.
Step-by-step explanation:
Consequently, because the decision is taken on the test based on the use of alpha equals 0.025, the p-value of the test must have been greater than the given amount of importance that is 0.025 since the test is not applicable to us. So, p > 0.025.
If we know that p > 0.025, that would not mean p > 0.1 as well, because we do not know with the details given he had to make the same decision for 0.1 degree of meaning.
As for the 0.01 significance point, we 're sure p > 0.01 is greater than 0.025, so the test does not matter.
