A.) C(g) = 2.75g for 0 < g ≤ 10
2.50g for 10 < g ≤ 12
c.) Domain is (0, 12] gallons
Range is (0, 30] dollars.
The answer is 64, rounded from 64.2.
To get this, you just have to add all the numbers up, and then divide your answer by the amount of numbers you added (just for future reference in problems like these!). To round to the nearest whole number, you look at the decimal: .2. It's closer to 0 than it is to 10, so the 64.2 would round down to 64.
I hope this helps!
Answer: The second derivative of the function is
Step-by-step explanation:
Since we have given that
We need to find the second derivative of the function.
So, the first derivative would be
Now, second derivative would be
Hence, the second derivative of the function is
Answer:
what does the picture say?
Step-by-step explanation:
Answer:
Number 1 can form a right triangle. Numbers 2 & 3 cannot.
Step-by-step explanation:
To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side. In other words, do the Pythagorean Theorem.
5² + 12² = 13²
25 + 144 = 169
169 = 169
<u><em>They are equal therefore Number 1 can form a right triangle.</em></u>
5² + 7² = 9²
25 + 49 = 81
74 = 81
<em>They are not equal, therefore Number 2 can't form a right triangle.</em>
<em />
10² + 12² = 30²
100 + 144 = 900
244 = 900
<em>They are not equal, therefore Number 3 can't form a right triangle.</em>
