Find the domain and the range of the relation shown on the

Mathematics
1 answer:

Answer:

Domain = {0.-6}

Range = {-2, 4}  

Notes We find coordinates and radius and state

Then we show formula  (x -x1)^2 + (y +y1) = r ^2 and show

(x -3 )^2 + (y − 1)^2 = 9 = R^2  THE RADIUS^2

then ;

Domain formula = x - r   and x + r

Range formula = y - r  and  y + r

Step-by-step explanation:

The graph is a circle so all the points are enclosed in it

The domain is the values for x so you subtract the radius from the centre coordinate and you add the radius to it The range is the values for y so you do the same to the y coordinate If you use

(x- x1) ^2 + (y - y1) ^2

(x -3 )^2 + (y − 1)^2 = 9

However this changes if centre coordinate shows negatives

we change negative x or y to + positive in the formula in bold.

Centre coordinate = (3.,1) radius is 3  SO = MUST BE THE RADIUS ^2

= (x - 3)^2 + (y - 1)^2 = 3^2  = 9  

Domain formula = x - r   and x + r

Domain  = 3 - 3 = 0

and - 3 + 3 = -6

Domain = {0.-6}

Range formula = y - r  and  y + r

Range = 1 - 3 = -2

and  1 +3 = 4

Range = {-2, 4}

Answer:

Yes, because the x's do not have more than one y.

Step-by-step explanation:

x      y

0      0

5       10

6       12

10     20

(That's meant to be a table). Looking at the x and y table values, you can see that none of the x's have two y's. So, this relation is a function.

For a moving object, the force acting on the object varies directly with the objects acceleration. When the force of 63 N acts o
Serjik [45]

Answer:

49N

Step-by-step explanation:

Step one

Given

When the force of 63 N acts on a certain object

the acceleration of the object is 9/ms^2

Firstly, we need to calculate the mass m

F=ma-------1

m= F/a

m= 63/9

m= 7kg

Step two:

Also, if the acceleration of the object becomes 7 m/s^2

then the force

Note: the mass remains the same= 7kg

F=ma

F=7*7

F= 49N

Sally can detail a car in 50 minutes. Manny does the same job in 35 minutes. How long will it take them to detail a car working
Debora [2.8K]

<u>Answer:</u>

Both Sally ans Manny can detail a car in 20.6 min.

<u>Solution: </u>

Let us assume that together they will take total x minutes to detail the car.

Sally detail the car in 50 min.

So in 1 min sally can detail \left(\frac{1}{50}\right) of the car.

Hence in x min sally can detail \left(\frac{x}{50}\right) of the car.

Manny can detail a car in 35 min.

So in 1 min many can detail \left(\frac{1}{35}\right) of the car.

Hence in x min Manny can detail \left(\frac{x}{35}\right) of the car.

So we can say,

\left(\frac{x}{50}\right)+\left(\frac{x}{35}\right)=1

x\left(\frac{1}{50}+\frac{1}{35}\right)=1

x\left(\frac{7+10}{350}\right)=1

\left(\frac{17 x}{350}\right)=1

17 x=350

x=\left(\frac{350}{17}\right)=20.5 8\approx 20.6

So, both of them can detail a car in 20.6 min.
