€ = 7/9
7/9÷2 = .389
C = 2pi•r = 2•pi•18 = 36pi
WV = 7/9 (36pi) = .389 (36)pi = 14pi
So C) 14pi is the answer
Question:
Give all the x and y intercept of the function
![f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B3x%5E2%20-%203x-60%7D%7B2x%5E3%20%2B%202x%5E2-34x%2B30%7D)
Answer:
The x intercepts are x = 5 and x = -4
The y intercept is at y = -2
Step-by-step explanation:
Factorizing the numerator of the expression we find the x intercepts as follows;
![f(x) = \frac{3x^2 - 3x-60}{2x^3 + 2x^2-34x+30} =\frac{3(x-5)(x+4)}{2x^3 + 2x^2-34x+30}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B3x%5E2%20-%203x-60%7D%7B2x%5E3%20%2B%202x%5E2-34x%2B30%7D%20%3D%5Cfrac%7B3%28x-5%29%28x%2B4%29%7D%7B2x%5E3%20%2B%202x%5E2-34x%2B30%7D)
Therefore, the x intercept are
x = 5 and x = -4
To find the y intercept, we put x = 0 to get y = -2
Therefore, the y intercept is at y = -2
Factorizing the denominator we find the values for which the equation is undefined
2·x³ + 2·x² - 34·x + 30 = 2·(x-1)·(x-3)·(x+5) which gives
x = 1, 3 and -5.
It would be 9x^3+6x^2+12x+8
53 3/4=53.75
To find out how many 4ft ropes you can make divide 53.75 by 4
53.75/4=13.4375
You can make 13 4ft ropes out of a 53.75ft rope
