Answer:
307 Meters
Step-by-step explanation:
It does matter, the second inequality would be correct because it list that when n is inputted it can be 28 or greater. However, in the first inequality it states that when n is inputted it has to be greater then 28 but cannot be 28.
B.
You can get this by using the quadratic equation, which I listed below.
With a = 2, b = 1, c = -45
Answer:
24/3-4
Answer is 12
Step-by-step explanation:
To find the answer, you have to work backwards. You also have to use PEMDAS. Since she multiplied her answer to get 24, you have to work backwards and divide by 3 first. You will get the number 8 after that because 24/3 is 8. Since she also subtracted 4, you have to work backwards and add 4. That gives you an original number of 12.
Answer: ((x^2 + 3)^9)/9 +c
Step-by-step explanation:
Let, x² + 3 = u
⇒2x dx = du
Now, substituting, we get,
∫u^8 du
= (u^(8+1))/(8+1)
= (u^9)/9
= ((x^2 + 3)^9)/9 +c
