Answer:
X=3252
Step-by-step explanation:
Your formula is $49645+$12.25x=$15499+$22.75x
X represents the number of books sold.
$49645+($12.25*3525)=$39,837
$15499+($22.75*3252)=$39,837
Hello,
A cubic polynomial with -2,1,2 as roots is
f(x)=k*(x+2)(x+1)*(x-2)=k(x²-4)(x+1)=k(x^3+x²-4x-4)
Looking the answers ==>k=1
==>Answer A
Answer:
BC= 2√5
CD= 2√10
DE= 2√5
BE= 2√10
slope of BC = 2
slope of CD = 1/3
slope of DE = 2
slope of BE = 1/3
Step-by-step explanation:
formula for distance = √(x2-x1)²+(y2-y1)²
formula for slope = (y2-y1)/(x2-x1)
Answer:
480 cm²
Step-by-step explanation:
New side lengths:
80% of 30 cm = 0.8% × 30 cm = 24 cm
80% of 25 cm = 0.8 × 25 cm = 20 cm
area = length × width
area = 24 cm × 20 cm
area = 480 cm²
Answer:
144.75in^2
Step-by-step explanation:
V=bh/3
so..
V=(18.4)(23.6)/3
V=434.24/3
V=144.74666
round to the nearest tent
V=144.75 inches
