Answer:
12.5%
Step-by-step explanation:
2.56-2.24 =0.32
By using the rule of three we can find the answer.
we have that 2.56 = 100% so we have to find what percentage 0.32 represents
(0.32*100)/2.56 = 12.5

Answer:
(a) 36
(b) y = 36x-31
Step-by-step explanation:
(a) dy/dx = 18x
slope of tangent at (2, 41) = 18(2)
= 36
(b) using y-y1 = m(x-x1)
y-41 = 36(x-2)
y = 36x-31
(2p + 7)(3p-9)
2p x 3p= 6p^2
2p x -9= -18p
7 x 3p=21p
7 x -9=-63
6p^2 - 18p + 21p - 63
6p^2 + 3p -63 is the answer.
