Answer:

D;

(x + 1/2)^2 + (y- √57)^2 = 81

Step-by-step explanation:

Mathematically, the general equation of a circle is given as;

(x-a)^2 + (y-b)^2 = r^2

where (a,b) represents the circle center and r represents the radius of the circle

Thus, we have this as follows;

(a,b) = (-1/2, √57) , r = 9

Substituting these values;

(x + 1/2)^2 + (y- √57)^2 = 9^2

(x + 1/2)^2 + (y- √57)^2 = 81

Which of the following points is in the solution set of y < x 2 - x - 6?
Georgia [21]
Y< X^-X-6

1. Solve the x first by factor.
2. X equals to (x-3)(x+2). X=3 or -2.
3. Looking at the problem, we see two similar answers with 3 and -2.
4. The correct answer is D, y=0. Because 0 is less than 3, choice A fails because y is greater than x.

904.32 is the volume.

Volume of sphere

= (4/3)πr³

= (4/3) × 3.14 × (6cm)³

= (4/3) × 3.14 × 6cm × 6cm × 6cm

= 4 × 3.14 × 2cm × 6cm × 6cm

= 904.32 cm³

After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

A pumpkin pie recipe says to bake the pie at 425°F for 15 minutes, and then to adjust the temperature down to 350°F for 45 additional minutes.

The function P(t) gives the oven temperature setting t, in degrees Fahrenheit, t minutes after the pie is placed in the oven.

Diego discovers that the temperature inside the oven is always 25 degrees warmer than the oven’s temperature setting.

The function B gives the actual temperature of Diego’s oven.

If P(30) = 350. Then the corresponding point on the function B will be

The temperature function can be written as

P(t)=\begin{Bmatrix}425 & 0\leq t\leq 15 \\\\350 & 15 < t\leq 60 \\\end{Bmatrix}

The value of t = 30 lies in the interval of 15 < t ≤ 60.

After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.

More about the function link is given below.
