Answer:
Step-by-step explanation:
First, divide by 2 from both sides of equation.
Then, solve.
Subtract by 6 from both sides of equation.
Solve to find the answer.
, which is our answer.
Answer:
b = 363
Step-by-step explanation:
Sum of a geometric Progression is expressed as attached.
a = 3 = the first term
r = 3 = the common ratio
n = 5 = number of term
Sum of GP = a(r^n - 1)/ r-1
= 3(3^5 - 1)/ 3-1
= 3(234 - 1) / 2
= 3(242) / 2
= 726/2
= 363
Answer:
see below
Step-by-step explanation:
x + 10 = 5
Subtract 10 from each side
x + 10-10 = 5-10
x = -5
x - 3 = 6
Add 3 to each side
x - 3+3 = 6+3
x = 9
Oh, well that is just weird because the sixth student could be below average, average, or above average so there really is no way to tell. At least not from what I know now.
Answer:
number of units for cost to be minimum=150
Step-by-step explanation:
y=2x^2-600 x+49000
dy/dx=4x-600
dy/dx=0 gives 4x-600=0
4x=600
x=150
d^2y/dx^2=4x
at x=150,d^2y/dx^2=4*150=600>0
so y is minimum at x=150
