Step-by-step explanation:
I take it this is meant to be a multiplication, right ?
not a "function of function", which would be symbolized by a little empty circle.
to multiply 2 function means basically the same as to add, subtract or divide 2 functions : to apply the arithmetic operation in both expressions.
(f×g)(x) = (-2x² + 4x)(x² + 18x + 77) =
= -2x⁴ - 36x³ - 154x² + 4x³ + 72x² + 308x =
= -2x⁴ - 32x³ - 82x² + 308x
Answer:
4cm^2
Step-by-step explanation:
Area of parallelogram = base × height
Area = 4 × 1
= 4cm^2
Answer:
3.75
Step-by-step explanation:
1.5 equals 30 ft so x2 equals 60 then 15 is half of 20 so half of 1.5 in is .75 so 3 plus .75
Decay equation= P*(1-r)^t
P= Principal amount= $30,000
r= rate=0.065
t= time (in years) =5
x=30,000(1-0.065)^5
The value of the car in 5 years is approx. $21,438
