P(x)=f(x)*g(x)
P(x)=(x-400)(1,200-2x)
P(x)=1,200x-2x^2-480,000+800x
P(x)=-2x^2+2,000x-480,000

Answer: Option <span>D. P(x) = -2x2 + 2,000x - 480,000</span>

Answer:

Option (D) is correct.

P(x)=-2x^2+2000x-480000

Step-by-step explanation:

Given : The number of units produced in May is given by function f(x) = x-400

and the manufacturer's profit per unit for May is given by the function g(x) = 1200-2x

We have  to determine the  total profit the manufacturer can earn in May, P(x).

Consider the given data

Since,   The number of units produced in May is given by function f(x) = x-400

and the manufacturer's profit per unit for May is given by the function g(x) = 1200-2x

Total profit that the manufacturer can earn in May is given by the product of number of units produced with the profit per unit.

that P(x)=F(x)\cdot G(x)

Substitute the values, we get,

P(x)=(x-400)\cdot(1200-2x)

Simplify, using FOIL method \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd

=x\cdot \:1200+x\left(-2x\right)+\left(-400\right)\cdot \:1200+\left(-400\right)\left(-2x\right)

We get,

P(x)=-2x^2+2000x-480000

Thus, Option (D) is correct.

katovenus [111]

Answer:

  • <u>The rate of return is 8.15%</u>
  • <u>This is a good investment</u>

<u></u>

Explanation:

For the first question, you need to find the rate that makes the present value of a stream of ten constant annual payments of $15,000 equal to the $100,000 investment.

The formula that returns the present value of a constant payment is called the annuity formula and is:

      Present\text{ }value=payment\times \bigg[\dfrac{1}{r}-\dfrac{1}{r(1+r)^t}\bigg]

In your problem you know:

  • Present value: $100,000
  • payment: $15,000
  • r: ?
  • t: 10

You cannot solve for r directly. You must guess a value and calculate the right side of the equation until to you find the rate that makes it equal to 100,000.

Try 5%:

       \$15,000\times \bigg[\dfrac{1}{0.05}-\dfrac{1}{0.05(1+0.05)^{10}}\bigg]=\$115,826

Then, the rate of return is greater than 5%. After several trials you will find that the rate of return is 8.15%.

Since this rate is higher than 8%, which is what the company requires, this is a good investment.

A race
sashaice [31]

Answer: 187.7 mph

Step-by-step explanation:

v = 125 mph

t = 1.2 min

v2 = ?

t2 = 0.8 min

We can use the rule of 3 here. It's the inverse rule of 3 because as time decreases, speed increases.

\frac{125mph}{x} =\frac{1.2min}{0.8min}

x = \frac{(125)(1.2)}{0.8}

x=187.5mph
