The vertex of the parabola below is at the point (-4,-2) wich of the equations below could be the one for this parabola

MrRissso [65]

The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation $y(x)=a(x+4)^2-2$ where $a$ is any real number with the exception that $a\neq 0$ .

The reason any equation of the form $y(x)=a(x+4)^2-2$ works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola $y=x^2$ . The different variations are archived by varying the constant $a$ . When $a$ is negative, the parabolas will face downwards. When $a$ is negative, the parabolas will be face downwards.

A and B play a game in which they alternately toss a pair of dice. The one who is first to get a total of 7 wins the game. Find

kompoz [17]

Answer: the probability that the first toss wins is:

P = 1/6 or 0.1667

Step-by-step explanation:

A die has six sides (that is 6 outcome per die)

For a pair of dice:

The Total number of possible outcomes = 6 × 6 = 36

The possible outcomes of 7 is:

(1,6),(2,5),(3,4),(4,3),(5,2),(6,1)

= 6

The probability P of getting 7 is:

P = number of possible outcomes of 7/total number of possible outcomes

P = 6/36 = 1/6

The probability that the first toss wins

P = 1/6 or 0.1667

Circle O has is centered at (9, 9) and passes through (4, 9). What is the length of the diameter?

Amiraneli [1.4K]

Answer:

10 units

Step-by-step explanation:

Because the center of the circle is at (9 , 9) and passes through (4 , 9), the radius must be 5.

Radius - The length from the center of a circle to its edge

Diameter - The length from one edge of a circle to the opposite edge

The diameter is double the length of the radius, meaning D = 2(5).

2 × 5 = 10

So, the diameter of the circle is 10 units.

What is the gcf of 45 and 60 using prime factorization?

Temka [501]

45 = 3×3×5

60 = 2×2×3×5

Factors that are common to both products are 3×5.

3×5 = 15 is the GCF of 45 and 60
