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.

Answer:He is wrong because did not multiply 1.6 by 357.85 correctly.
Step-by-step explanation:
The weight per square foot of zinc roofing is 1.6 pounds. Jose wants to order 357.85 square feet of roofing. The total weight of 357.85 square feet of roofing would be
1.6 × 357.85 = 572.56 pounds
His calculation was
357.85 times 1.6 = 214710. 214710 + 35785 = 178.925
He is wrong because did not multiply 1.6 by 357.85 correctly.
Answer:
1/2 is the fractional part of cookie which was eaten by Dan.
Step-by-step explanation:
Dan has 2 1/2 cookies and ate 1/2, so we can just subtract the 2 1/2-1/2
which cancels out the 1/2, which is the fractional part.
He has 2 cookies left.
