Solve 2x3 + x2 - 15x completely by factoring.

Ludmilka [50]

2x^3+x^2-15x factored completely would be: x(x+3)(2x-5). Not sure which answer choice but I hope that I was some help.

Question 2 2.1 2.2 2.2.1 2.2.2 Determine the general solution for sin(x - 30°) = cos 2x Consider the functions f(x) = sin(x-30°)

OLEGan [10]

The general solution for the given equation is 40°+120°n.

The period of g(x) is π.

The range of f(x) is [-1, 1].

sin(x-30°) = cos 2x
sin(x-30°) = sin(90°-2x)
(x-30°) = (90°-2x) + 360°n
x + 2x = 90° + 30° + 360°n
3x = 120° + 360°n
x = (120° + 360°n)/3
The general solution (x) is 40° + 120°n.

g(x) = cos 2x
The period of cos x is 2π.
If the multiplying factor of x is 'n', then it decreases the period by n times.
Here, in g(x), n is 2.
The period of g(x) is equal to half the period of cos x.
The period of g(x) = 2π/2
The period of g(x) is π.

f(x) = sin(x-30°)
"Sin" is a trigonometric function which has a range from -1 to 1.

A) find the value of 2x+y wehn x =4 and y =3 b) find the value of a^2 + b when a = -2 and b = 5

Reil [10]

Answer:

Solution,

a. Given,

X=4

y=3

Now,

 $2x + y \\ = 2 \times 4 + 3 \\ = 8 + 3 \\ = 11$ 

b. Given,

a=-2

b=5

Now,

 ${a}^{2} + b \\ = {( - 2)}^{2} + 5 \\ = 4 + 5 \\ = 9$ 

hope this helps...

Good luck on your assignment..
