Answer:
The statements 1 and 4 are true.
Step-by-step explanation:
In order to quickly visualize the center and radius of the circle we can manipulate the given equation in such a way that it changes to the standard form.
Now that the equation is its standard form we can compare it to the standard form formula to determine the center and radius of the circle:
Where 
are the coordinates of the center of the circle and 
is the radius of the circle. Therefore the circle we were given has center in (1,0) and radius 
. With this in mind we can analyze each statement.
1. The radius of the circle is 3 units. This statement is correct.
2. The center of the circle lies on the y-axis. This statement is false, since the center of the circle has the coordinates (1,0) it means that it actually lies in the x-axis.
3. The standard form of the equation is (x - 1)² + y² = 3. This is false the correct standard equation is (x - 1)² + y² = 9.
4. The radius of the circle is the same as the radius of the circle who's equation is x² + y² = 9. This statement is correct, the radius is given by the square root of the constant on the right side of the equation, therefore the radius of both circle is 3.
Cos28 = x/4 so to get rid of the fraction , multiply each side by 4 so it'll be
4cos28 = x
x = 3.531790371
Hope this helps=)
Keep in mind its been a while since i did this type of work lol.....
did you try to draw it out on a grid paper....what will be helpful is if you got the coordinates and put the points down and then if you connect the dots you get your shape now you will count the unis in which the width and length is timed. so like if you had grid and it gave you coordinates and you did all that now you will count how many units is in the width and how many in the length.
but your best answer might be 14 units x 4 units
Answer:
The answer is 24.

Answer:
It's C
Step-by-step explanation:
Your graph should be this one, with both lines solid because, the X line, or red, has to be at least -1 or higher, and the Y line, or the blue, has to be +4 or higher
