Answer:
245.04
Step-by-step explanation:
A=2πrh+2πr2=2·π·3·10+2·π·32≈245.04423
Divide 6 by 2 to find the radius
Answer:
Step-by-step explanation:
a) The amount of concern is ...
(total interest)/(number of payments) = interest/payment
$14,644.95/120 ≈ $122.04 . . . . amount of interest per payment
__
b) The ratio of concern is ...
(total interest)/(total payments) × 100% = 14,644.95/39,644.95 × 100%
≈ 36.94% . . . . percent of total payments that is interest
Answer:
No
Step-by-step explanation:
Two consecutive sides means that the two sides are connected in a shape by a vertex. If the sides were parallel, they would have to be right on top of each other, so two consecutive sides cannot be parallel.
X3-7x=6x-12
x3-7x-6x+12=0
x3-13x+12=0
(x-1)(x2+x-12)=0
Calculate delta of the second bracket:
delta = 1+4*12=49
sqrt(delta)=sqrt(49)=7
x_1=(-1-7)/2=-4
x_2=(-1+7)/2=3
(x-1)(x+4)(x-3)=0
Answear:
Roots: x=1, x=-4, x=3.
