Answer:
40 cm^2.
Step-by-step explanation:
Area = the sum of the 2 triangles
= 1/2 * 6 * 8 + 1/2 * 4 * 8
= 24 + 16
= 40 cm^2.
Answer:
Step-by-step explanation:
Your question is unclear. What are "major intercepts"?
x²/81 + y²/64 = 1
The major axis is horizontal.
0²/81 + y²/64 = 1
y-intercepts = ±8
x²/81 + 0/64 = 1
x-intercepts = ±9

Answer:
83,491.67 dollars
Step-by-step explanation:
Given that a certain electronics manufacturer ound that the average cost C C to produce x DVD/Blu- ray players can be found using the equation 
To find the minimum average cost per machine we can use derivative test.
we find first and second derivative.
If for a particular value of x first derivative is 0 and second derivative is positive, then that x satisfies the minimum cost criteria.

Second derivative is always positive
I derivative =0 gives

For 83 players the cost would be minimum
Minimum cost =
