Answer:

The value of the given function f(x) at x = 0 is 0

Step-by-step explanation:

The function is given to be :

f(x)=\tan^{-1}x

Now, we need to find the value of the given function f(x) when x = 0

So, To find f(0) we substitute x = 0 in the given function f(x)

\implies f(x)=\tan^{-1}x\\\\\implies f(0)=\tan^{-1}(0)\\\\\implies f(0)=\tan^{-1}(\tan 0)\\\\\implies f(0)=\tan^{-1}\tan(0)\\\\\implies f(0)=0

Therefore, The value of the given function f(x) at x = 0 is 0

Answer:

  • P(y) = 0.005y² -10y -1000000
  • 3,200,000

Step-by-step explanation:

a) Profit is the difference between revenue and cost.

  P(y) = R(y) -C(y)

  P(y) = (0.005y² +10y) -(20y +1000000) . . . . use the functions for revenue and cost

  P(y) = 0.005y² -10y -1000000 . . . . . profit as a function of y

___

b) Evaluating this function for y=30,000, we get ...

  P(30000) = 0.005(30000)² -10(30000) -1000000

  = 3,200,000

The company will have a profit of 3,200,000 from the sale of 30,000 cars.

9.Lawson will pay $612 to three different credit cards: Expert Card, Passport, and US Speedy. He will pay five times as much to
andre [41]

Answer:

$102

Step-by-step explanation:

We need to build a system of equations for this question.

I am going to call x the value Lawson will pay to Expert Card, y the value he will pay to passport and z the value he will pay to US Speedy.

He will pay $612 in all, so x+y+z = 612.

He will pay 5 times as much to Expert Card as US Speedy, so x = 5z.

The passport payment will be only 20% of the total of the other two payments. So y = 0.2(x+z).

Now we have the following system of equations:

1)x+y+z = 612

2)x = 5z

3)y = 0.2(x+z)

And we need to find y.

I will put 2) and 3) at 1). We end up with:

5z + 0.2(5z+z)+z = 612

5z + 1.2z + z = 612

7.2z = 612

z = $85

Knowing z, now we can find y at 3)

y = 0.2(x+z)

y = 0.2(5z+z)

y = 1.2z

y = 1.2(85)

y = $102

Lawson will pay $102 towards the passport credit balance.
