Answer:
- C. f(x) = x³ + 10x² + 7x - 18
Step-by-step explanation:
If the function has a factor of x + 9, then the function will have a zero output at x = -9
<u>Lets verify:</u>
- A. f(-9) = (-9)³ - 8*(-9)² - 11*(-9) + 18 = -1260, No
- B. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 27 = -9, No
- C. f(-9) = (-9)³ + 10*(-9)² + 7*(-9) - 18 = 0, Yes
- D. f(-9) = (-9)³ - 8*(-9)² + 11*(-9) + 27 = -1449, No
Since (AB) ̅≅(AD) ̅ (the lines beside the parentheses are to show that they are lines) we have congruent hypotenuses. (AC) ̅≅(AC) ̅ so legs are ≅ So, es; ΔACB≌ΔACD by HL. The answer is D.Yes; ΔACB≌ΔACD.

Answer: 78.5 ft
Step-by-step explanation: 25 times 3.14
Answer:
32
Step-by-step explanation:
The formula needed to solve this question by hand is:
![x^{\frac{m}{n}} =\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D)
256^(5/8) = 8th root of 256^5
256^(5/8) = 8th root of 1280
<u>256^(5/8) = 32</u>
