Write a linear factorization of the function.
mart [117]

Answer:

  f(x) = x^2 (x + 7i)(x - 7i)

Step-by-step explanation:

Factoring out x^2 gives ...

  f(x) = x^2(x^2 +49)

The factor with 49 can be considered to be the difference of two squares, where one of the squares is -49. Then its square root is ±7i, and the factorization of that term is ...

  x^2 +49 = (x +7i)(x -7i)

So, the overall factorization of f(x) is ...

  f(x) = x^2(x +7i)(x -7i)

A jet leaves Reno, Nevada and is headed toward Miami, Florida at a bearing of 100°. The distance between the two cities is appro
Likurg_2 [28]
So hmm, if you notice the picture below

"y" would be the opposite to the 10° angle, and "x" would its adjacent

Reno is "y" north and "x" west from Miami

\bf sin(\theta)=\cfrac{opposite}{hypotenuse}\implies sin(10^o)=\cfrac{y}{2472}  solve for "y", to see how much north

and \bf cos(\theta)=\cfrac{adjacent}{hypotenuse}\implies cos(10^o)=\cfrac{x}{2472}  solve for "x" to see how much west

make sure, that in both cases, your calculator is in Degree mode, since the angle is in degrees, as opposed to Radian mode


now... for the section B)

if notice the Reno-Miami line, and you were to draw a North line through it, anywhere in between, or at an endpoint like the in the picture at Reno, the "clockwise" angle, will always be the same, 100°

bear in mind ( no pun intended ), that Bearings use the North line, and the clockwise angle from it, as in the picture below

F(x)=-9x^2-7x+8, x=5
VashaNatasha [74]
F(x) = -9x^2 - 7x + 8
f(5) = -9(5^2) - 7(5) + 8
f(5) = -9(25) - 35 + 8
f(5) = - 225 - 35 + 8
f(50 = - 252 <==

Radda [10]

Answer:

D. More students preferred band or chorus than those that preferred football.

Step-by-step explanation:

I can easily tell D is the answer because 16+14=30. This means 30% liked band or chorus and 26% liked football.
