7 0

Answer:

  D

Step-by-step explanation:

The point you're looking for is the same distance from the origin, but 15° clockwise around a circle centered at the origin. Points A and D are the only ones with the same radius. Point D is the only one that is 15° clockwise from P.

_____

The approximate coordinates of the rotated point are (-4.3120, 3.2259).

The area of this rectangle is given by the quadratic function
Sonja [21]

<em>The function uses W as the variable but the options show only x's as the variable, so I'm asumming W in the answer</em>

Answer:

0 < W < 50

Correct option: A

Step-by-step explanation:

<u>Domain of functions</u>

Some functions have restricted values of the independent variable x. It can be due to mathematical restrictions, like dividing by 0 or taking the square root of a negative number, of it can be due to practical conditions of the situation being modeled.

In this case, the area of a rectangle is given by the quadratic function.

A=50W - W^2

Since the area of a rectangle cannot be negative (and should be positive, though it could be zero), the practical domain of A is determined when

50W - W^2\geq 0

Taking common factor W

W(50 - W)\geq 0

Since W must be positive W>0

50 - W\geq 0

Or equivalently

50 \geq W

W \leq 50

The total interval is

0 < W

Correct option: A

Please note: The real restriction should be

0 < W\leq 50

if we allowed the area to be positive, but I'm providing the most possible correct available option

PLEASE HELP ITS DUE IN 7 MINUTES!​
Tju [1.3M]

Answer:

X\geq -5

Step-by-step explanation:

4x+6\geq 6x+10\\-6x           -6x\\4-6=-2\\-2x+6\geq 10\\     -6          -6\\\frac{-2x}{-2} \geq \frac{10}{-2} \\x\geq -5

Hope this helps

Three times the square of a certain positive number exceeds six times the number by nine. find the number:
d1i1m1o1n [39]
With the number being x, we have 3x^2>6(x/9). Expanding, we get 3x^2>6x/9 and 3x^2>2x/3. Dividing by x, we get 3x>2/3 and dividing by 3 we get x>2/9
