### The general form of the equation of a circle is x2 + y2 + 42x + 38y − 47 = 0. The equation of this circle in standard form is (x + 21)^2 + (y + 19)^2 = 849 . The center of the circle is at the point A(-19, -21) B(-21, -19) C(19, 21) D(21, 19) , and its radius is A. 127^(1/2) B. 849^(1/2) C. 851^(1/2) D. 47 units. The general form of the equation of a circle that has the same radius as the above circle is A. x^2 + y^2 + 60x + 14y + 98 = 0 B. x^2 + y^2 + 44x - 44y + 117 = 0 C. x^2 + y^2 - 38x + 42y + 74 = 0 D. x^2 + y^2 - 50x - 30y + 1 = 0 . Someone please help with those 3 multiple choice ones.

For the center of this circle the right choice will be choice B. (-21,-19)

and its radius sqrt849 = 849^(1/2) so choice B. is right for this too

### 7/20 in decimal form

Well, we would have to divide 7 into 20 in order to find the decimal, so 7 divided by 20 = 0.35, so 7/20 as a decimal is 0.35, and if you move the decimal two places to the left, it is also 35%.

### Multiplying a trinomial by a trinomial follows the same steps as multiplying a binomial by a trinomial. Determine the degree and maximum possible number of terms for the product of these trinomials: (x2 + x + 2)(x2 – 2x + 3). Explain how you arrived at your answer.

To determine the degree of the product of the given trinomials, you would multiply the term with the highest degree of each trinomial together. Both trinomials are degree 2, and when you multiply x2 by x2, you add the exponents to get x4. Thus, the degree of the product is 4. If the product is degree 4, and there is only one variable, the maximum number of terms is 5. There can be an x4 term, an x3 term, an  x2 term, an x term, and a constant term.

To solve this type of problems, the easiest way to compare is to change them all to fractions, or to decimals, whichever is easier for you.

For the first one, change them all to decimals,
A. 525/1000=0.525
B. 3/4 = 0.750
C. 0.55 =0.550
Thus it will be obvious, whether you'd like smallest to biggest or otherwise.

For the second problem,
A. 3.85=3.850
B. 3 5/8 = 3.625
C. 3.805 = 3.850

Choose the smallest to biggest.

### The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. What are the coordinates of the vertex of the graph? (−9, −2) (−17, −2) (−2, −17) (−2, −9)

Option D is correct.

The coordinate of the vertex of the graph is, (-2, -9)

Step-by-step explanation:

Given the function:

it is given that: the axis of symmetry for a function is, x = -2

Also, the axis of symmetry divides the parabola into two equal parts.

So,  if there is a point on one of the side, there is a  corresponding point on the other side that is the same distance from the axis of symmetry and has the same y-value.

Also, the x-coordinate of the vertex is x = -2.

Substitute the x values in the original equation to find the value of y;

Simplify:

Therefore, the coordinate of the vertex of the graph is, (-2, -9)

Option C.

Step-by-step explanation:

Two beauticians Lydia and Jackie are working on your hair.

Lydia takes the time to complete the work = 2 hours

Per hour work done by Lydia = 1/2

Jackie complete the  work = 1 hour

In one hour total work done by both Jackie and Lydia together =

### Maria rented a coat at $285 for 3 days. If she rents the same coat for 6 days, she has to pay a total rent of$510. Write an equation in the standard form to represent the total rent (y) that Maria has to pay for renting the coat for x days.

The situation above is an arithmetic sequence with the third term (a3) equal to $285 and sixth term (a6) equal to$510. To determine the nth term of the arithmetic sequence, use the equation,
an = a1 + (n - 1)d
where a1 is the first term and d is the common difference. To solve for these, use the given values,
285 = a1 + (3-1)(d)
510 = a1 + (5 -1)(d)
Solving for the unknowns gives an answer of a1 = 60 and d = 112.5.Thus, the equation is,
y = 60 + 112.5x

### For all functions of the form f(x) = ax2 + bx + c, which is true when b = 0? The graph will always have zero x-intercepts. The function will always have a minimum. The y-intercept will always be the vertex. The axis of symmetry will always be positive.

The y-intercept will always be the vertex.

Explanation:

The vertex is found by first finding the axis of symmetry, using the formula

x = -b/2a

If b = 0, this gives us

x = 0/2a = 0

This means the point (0, c) will be the vertex.  This is also the y-intercept.
