Answer:B. 86
Explanation: 1032/12=86
There are 8! Eight sides on the shape, and all sides are the same shape.
Answer:
1/ab en (c/be^-x+c)
Step-by-step explanation:
Sure is a harsh question! Here's my Explanation
b+ce^x = t
ce^x an = dt
e^xan = dt/c
an = dt/ce^x = dt/c(t-b/c) = at/(t-b)
en = t-b/c
A/b+ce^x dx = a/t dt/t-b
a ∫1/t (t-b) dt = 1/a∫ (1/(t-b) - 1/t) dt
= 1/ab [∫1/(t-b) dt + ∫-1/t dt]
= 1/ab [en (t-b) - en(t)]
= 1/ab en ((t-b)/t)
t = b + ce^x
= 1/ab en (b+ce^x -b/b+ce^x)
=1/ab en (ce^x/b+ce^x)
= 1/ab en (c/be^-x+c)
A decrease by 30%, means that the price is now 70% of the original price ( 100% - 30% = 70%)
To find the original price divide the new price by the percent of the original price it is now.
147 / 0.70 = 210
The original price was £210
Step-by-step explanation:
let equation be y = mx + b.
m = (9- (-3))/(-4 - 2) = -2
sub (2, -3):
-3 = -2(2) + b
b = 1
therefore equation of the line is y = -2x + 1
