Answer:

B, f(x)=-7x^2-x+2

Step-by-step explanation:

Quadratic formulas must have only one degree which must also always be to the second power, and they cannot have a 0 as a coefficient, so that is the only sensible answer.

Once again co sines . Please help me and include explanation with a clear answer
vladimir1956 [14]

Using the law os cosines formula b^2 = a^2 + c^2 - 2*a*c*cos(B)

a = 17, b = 8, c = 16

8^2 = 17^2 + 16^2 - 2*17*16* cos(B)

64 = 289 + 256 - 544 * cos(B)

544*cos(B) = 289 + 256 - 64

544 * cos(B) = 481

cos (B) = 481/544

B = arccos(481/544)

B = 27.8 degrees

I need help with geometry
Zigmanuir [339]

Answer:

x= 98

y= 38

Step-by-step explanation:

First add 36 and 46. Then subtract the sum (82°) from 180° to get the value of x (98°). Use reflection to realize that x and the angle across from it are the same value. Add 98 to 44. Then subtract the sum (142°) from 180° to get y (38°).
