Answer:
c=45 and A=145
M=15 and L=115
Step-by-step explanation:
Answer:
zeroes: x = -9 and x = -7
Step-by-step explanation:
f(x)=(x+8)^2−1
A "zero" refers to when the y-value on the graph is zero.
0 = (x+8)^2 - 1
1 = (x+8)^2
+ or - 1 = x+8
so break them apart into two equations
x+8 = 1 OR x+8 = -1
x = -7 OR x = -9
You can plug both back in to check that the equation works!
Answer:
Step-by-step explanation:
60 to 15 = x to 70
60/15 = x/70.....cross multiply
15x = 4200
x = 4200/15
x = 280 <=== answer A
X = k/p^3
125 = k/10^3 = k/1000
1000 x 125 = k
k = 125000
x = 125000/p^3
The profit is given by G = px - (125 + 2x) = p(125000/p^3) - 125 - 2(125000/p^3) = 125000/p^2 - 250000/p^3 - 125
For maximum profit:
dG/dp = 0
dG/dp = -250000/p^3 + 750000/p^4 = 0
750000 - 250000p = 0
p = 750000/250000 = 3
Therefore the price that will yeaild maximum profit is $3.
Answer:
$408
Step-by-step explanation:
What we know:
John earns a 3% commission for every car he sells.
He sold a car today for $13,600.
Multiply 3/100 by 13,600 to get your answer.
3/100 * 13600
40800/100
$408 in commission
