Answer:
Tisco
Step-by-step explanation:
T=1.65x4 is 6.6
A=1.36x5 is 6.8
6.8>6.6
sry if wrong
I believe it would just be b=1m or b=m. the reason i added the 1 in front of the m was to show you that the books would equal 1 per month. b and m are equal to each other because the rate is 1 book per 1 month.
Here are some prime numbers:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199
the equation of a vertically opening parabola is
(x - h)² = 4p(y - k)
where (h, k) are the coordinates of the vertex and p is the distance of the focus and directrix from the vertex. If 4p is positive parabola opens up and if 4p is negative parabola opens down
rearrange 12y = (x - 1)² - 48 into this form
(x - 1)² = 12y + 48
(x - 1)² = 12( y + 4) ← in standard form
Vertex = (1, - 4 )
4p = 12 ⇒ p = 3 ⇒ parabola opens upwards
the focus is above the vertex and the directrix is below the vertex in a vertically opening up parabola
Focus = (1, - 4 + 3 ) = (1, - 1)
Directrix has equation y = - 4 - 3 ⇒ y = - 7
