Answer:
0
Step by Step Explanation:
Answer:
f(2)=1/9
Step-by-step explanation:
f(x)=(1/3)^x
f(2)=(1/3)^(2)
f(2)=1/9
Divide both sides by -14.
Answer:
m=2
Answer:
912.414
Step-by-step explanation:
The angle
θ
between the directions of motion of planes
θ
=
320
−
200
=
120
∘
The distance
a
traveled by first plane flying at a speed of
150
km/hr
in
3
hrs
a
=
150
⋅
3
=
450
k
m
Similarly, the distance
b
traveled by second plane flying at a speed of
200
km/hr
in
3
hrs
b=
200x3=
600 km
Now, the distance between the planes after 3
hrs will be equal to the side of a triangle opposite to the angle θ=120∘
included by the sides
a
=
450
& b=
600
.
Now, using Cosine rule in the concerned triangle, the distance between the plane after
3
hours is given as
a. The total cost is the sum of variable and fixed cost.
So the average cost of each hat is simply total cost divided by x:
ave cost = (2.12 x + 3000) / x
b. Total cost should be equal to Income:
2.12 x + 3000 = 2.75 x
Solve for x:
x = 4762 units
c. Profit is income minus total cost:
Profit = 2.75 x – (2.12 x + 3000)
1000 = 2.75x – 2.12 x – 3000
Solving for x:
