Options
(0, 35)
(10, 30)
(15, 25)
(20, 15)
Answer:
(C) (15,25)
Step-by-step explanation:
The profit p in dollars of selling x widgets and y gadgets is given by the function p(x,y)=7x+6y.
Option A
When x=0 and y=35
p(x,y)=7(0)+6(35)
p(x,y)=210
Option B
When x=10 and y=30
p(x,y)=7(10)+6(30)
p(x,y)=250
Option C
When x=15 and y=25
p(x,y)=7(15)+6(25)
p(x,y)=$255
Option D
When x=20 and y=15
p(x,y)=7(20)+6(15)
p(x,y)=$230
We observe that the point (15, 25) in Option C yields the highest profit ($255). Therefore, it is the point that maximizes profit.
Answer:
894.19 mi/hr
Step-by-step explanation:
Total distance of the trip = 3990 mi
Let the speed of the sound be 'x' miles per hour
Now,
Total distance = Speed × Time
Therefore,
According to the question
3,990 mi = [ ( x - 120 ) × 0.1 ] + [ ( x + 410 ) × 3.0 ]
or
3,990 mi = 0.1x - 12 + 3x + 1230
or
0.1x + 3x = 2772
or
3.1x = 2772
or
x = 894.19 mi/hr
The answer to 17s-10+3(2s+1) is 23s-7
You have to add -17+(-7) when you get (-7) you have to add.
