Step-by-step explanation:
given = 8 - n
To calculate the first 3 terms substitute n = 1, 2, 3 into the formula
= 8 - 1 = 7
= 8 - 2 = 6
= 8 - 3 = 5
the first 3 terms are 7, 6, 5
the first negative value will occur when n > 8, that is 9
= 8 - 9 = - 1 ← first negative term
Answer:
f(x) = x^2 + 2, g(x )= -x + 1
=> (f*g)(x) = (x^2 + 2)(-x + 1)
= -x^3 + x^2 - 2x + 2

Answer:
Less than
Step-by-step explanation:
2/3*3/4=6/12. 6/12=1/2. 1/2=2/4. 2/4 is less than 3/4.

Answer:
2257 pounds
Step-by-step explanation:
First, get the volume of each and since density is the same, we shall use the density to get the other mass
First volume
Volume=lwh where l is length, w is width and h is height.
Substituting with the given figures
Volume=4*9*168=6048
Density
Density is mass per unit volume
D=m/v
Mass is given as 7900 pounds
Density is 7900/6048=1.3062169312169
Volume of second box
V=2*6*144=1728
Mass is product of volume and density hence 1.3062169312169*1728=2257.1428571428 pounds
Rounded off as 2257 pounds
