$20 per table, I work at a restaurant haha this is all I hear about
Answer:
$16,000
Step-by-step explanation:
Revenue is the product of price and the number sold. Using the given relation for number sold, the revenue as a function of price is ...
R(p) = p(-40p +1600) = -40p(p -40)
This is the equation of a quadratic that opens downward and has zeros at p=0 and p=40. The vertex is halfway between those zeros, at p=20. The revenue at this price is ...
R(20) = -40·20(20 -40) = 16,000 . . . . dollars

Arithmetic sequence
.
First step, find its difference
.
So, we get
.
Finally, Let's find the 75th term
Answer:
105
Step-by-step explanation:
Evaluate 4 a^3 - 2 b^2 + 5 where a = 3 and b = -2:
4 a^3 - 2 b^2 + 5 = 4×3^3 - 2×(-2)^2 + 5
3^3 = 3×3^2:
4×3×3^2 - 2×(-2)^2 + 5
3^2 = 9:
4×3×9 - 2×(-2)^2 + 5
3×9 = 27:
4×27 - 2×(-2)^2 + 5
(-2)^2 = 4:
4×27 - 24 + 5
4×27 = 108:
108 - 2×4 + 5
-2×4 = -8:
108 + -8 + 5

Answer: 105
Do you have a picture?
well if you have a square and a diagonal spiting the square into two triangles
that means that we can use 45 45 90 triangle and know that the sides will be
each side = 15
