Answer:

( − ∞ , ∞ ) { x | x ∈ R }

Step-by-step explanation:

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Answer:

see attached

Step-by-step explanation:

A right turn represents a clockwise rotation of the direction vector by 90°. It is equivalent to multiplying the complex number representation by -i.

A left turn represents a counterclockwise rotation of the direction vector by 90°. It is equivalent to multiplying the complex number representation by i.

Mike put 304 baseballs into 8 trash bins. He put the same number of baseballs in each bin. He took 5 trash bins of baseballs to

Solnce55 [7]

Answer:

190 Baseballs

Step-by-step explanation:

Since he put 304 baseballs into 8 trash cans with an equal amt. in each,

--> we do 304/8 to find how much baseballs we put in each

=> 304/8 = 38

Now, we takes 5 of these 38 trash cans filled with balls to the field

--> we would do 5 x 38 => 5 x 38 = 190

and Thus, we have our answer of 190 baseballs

Hope this helps!

Lim t—>0 1-cos(2t) / sin^2 (11t)

Nitella [24]

Answer:

2/121

Step-by-step explanation:

Hello,

Hôpital's rule will help here.

$\forall t \in \mathbb{R}^*\\\\f(t)=1-cos(2t)\text{ *** f is differentiable}\\f'(t)=2sin(2t)\\f''(t)=4cost(2t)\\f''(0)=4 \\ \\g(t)=sin^2(11t)\text{ *** g is differentiable}\\g'(t)=2sin(11t)\times 11 \times cos(11t)=2\times 11 sin(11t)cos(11t)\\\\g''(t)=2\times 11 (11cos^2(11t)-11sin^2(11t))\\g''(0)=2\times 11^2$

So the limit is 4/(2*121)=2/121

Thanks

Select the correct answer. What are the intercepts of y = 4x − 2?

Goshia [24]

Answer:

A is the correct answer

Step-by-step explanation:

To answer this you need to find the value for x that makes the y value zero.

and the value for y when x is zero.

There are 2 intercepts on for a linear equation. One x-intercept (where the graph crosses the x-axis) and one y-intercept (where the graph crosses the y-axis).

Step 1:

The x-intercept is found by setting 'y' equal to zero and solving the equation.

0 = 4x - 2 solve this...

2 = 4x (add 2 to both sides)

0.5 = x (divide both sides by 4 to get x by itself)

So the x-intercept is at the point (0.5. 0)

Step 2: The y-intercept if found by setting 'x' equal to zero and solving

y = (0)x - 2

y = -2

So the y-intercept is at the point (0, -2)
