Area of circle = π r²

<u>Here </u><u>, </u><u>We </u><u>have</u>

  • π = 3.14

  • r = diameter/2
  • r = 14/2
  • r = 7 ft.

Area of circle = 3.14 × (7)²

Area of circle = 3.14 × 49 ft²

Area of circle = 153.86 ft²

The cost of removing x percent of pollutants is expressed by the function 240x/100-x, where C is in thousands of dollars. Which
Nesterboy [21]
The correct answer is B) the cost of removing 80% of pollutants is $196,000.

Using the equation, we have
240(80)/(100-80) = 240(80)/20 = 196

Since this is in thousands of dollars, we have 196,000.

Using the equation, A is not correct; it would be 160,000.

The vertical asymptote would be at 100%.

B must be the correct answer.

A bookcase measures 13 ft wide and 24 ft tall. What would the bookcase's measurements be on a scale drawing using the scale 3 cm
qaws [65]

Answer:

19.5 cm wide

36 cm tall

Step-by-step explanation:

The given, 3 cm : 2 ft, is your first fraction (3 cm / 2 ft). We need to figure out how many cm is 13 ft and 24 ft. Let's start with 13 ft. We would use the first fraction, 3 cm / 2 ft, is equal to x cm / 13 ft. Then, you would cross multiply and get an answer of 19.5 cm. Now, we do the same thing but instead of 13 ft we need to use 24 ft. So again, 3 cm / 2 ft is equal to x cm / 24 ft. Then, cross multiply and get a final answer of 36 cm.

What is the quadratic equation if the solutions are -9+ √65 /2, -9- √65 /2
liberstina [14]

Answer:

4x^2+72x+259=0

Step-by-step explanation:

If x_1 and x_2 are the solutions to the quadratic equation, then this equation can be written as

(x-x_1)(x-x_2)=0

In your case,

x_1=-9+\dfrac{\sqrt{65}}{2}\\ \\x_1=-9-\dfrac{\sqrt{65}}{2}

Then the equation is

\left(x-\left(-9+\dfrac{\sqrt{65}}{2}\right)\right) \left(x-\left(-9-\dfrac{\sqrt{65}}{2}\right)\right)=0\\ \\\left(x+9-\dfrac{\sqrt{65}}{2}\right)\left(x+9+\dfrac{\sqrt{65}}{2}\right)=0\\ \\x^2+9x+\dfrac{\sqrt{65}}{2}x+9x+81+\dfrac{9\sqrt{65}}{2}-\dfrac{\sqrt{65}}{2}x-\dfrac{9\sqrt{65}}{2}-\dfrac{65}{4}=0\\ \\x^2+18x+\dfrac{259}{4}=0\\ \\4x^2+72x+259=0
