Which relation is a function? A) x y = y2 - 3 B) y x = y2 - 3 C) x2 + y2 = 5 + x D) x2 - y = 10x + 25 + y
marin [14]
Since you didn’t specify that it needed to be y as a function of x, all of the above equalities can be rewritten as functions. However, in case that you meant to imply that, A and B are both not valid for y as a simple function of x.

Do 14 and 15 for 80 points :)
Savatey [412]

Answer:

14) t=2hours

15)a=5/4

Step-by-step explanation:

14) The graph of y = -0.5 l t l is an inverted "V-shaped" graph with highest point when t = 0 and y = 0.  

To obtain the graph of r = -0.5 l t - 1 l + 0.5, translate the graph of                           y = -0.5 l t l one unit to the right and 0.5 units upward.  The highest point on this graph occurs when t = 1 and r = 0.5.

Maximum rate of rainfall = 0.5 inches/hr

The rain stops when r = 0.  So,  -0.5 l t - 1 l + 0.5 = 0

                                                   l t - 1 l = 1

                                                    t - 1 = 1 or t - 1 = -1

                                                    t = 2 or t = 0

t > 0, so the rain stops when t = 2 hours

15)The vertex of the path of the ball is (6, 0), so the equation

has the form y = a⎜x − 6⎟ . Substitute the coordinates of

the point (5, __5

15)The vertex of the path of the ball is (6, 0), so the equation

has the form y = a⎜x − 6⎟ . Substitute the coordinates of

the point (5, __5

4) into the equation and solve for a.

y = a ⎜x - 6⎟

_5

4 = a ⎜5 - 6⎟

_5

4 = a ⎜-1⎟

_5

4 = a

An equation for the path of the ball is y =

_5

4

⎜x − 6⎟.

What is the perimeter of a regular octagon with a side length of 7 inches?
Vedmedyk [2.9K]

Answer: 56

Step-by-step explanation:

The perimeter is just adding up all of the sides and we know an octagon has 8 sides, so you can just do 8 by 7 which is 56.

This circle is centered at the origin, and the length of its radius is 4. What is
Sonbull [250]

Answer:

D. x² + y² = 4²

Step-by-step explanation:

The general equation of a circle is given in the attached  graphic.

In this case, we can see that the center of the circle is at the origin i.e (0,0) and that the radius is 4 units.

the values for h, k and r in the general equation are as follows:

h = 0, k=0, r = 4

putting this into the general equation:

(x-h)² + (y-k)² = r²

(x-0)² + (y-0)² = 4²

x² + y² = 4²
