For this case we must locate each of the points in the graph and see if they are in the region.

The border of the region is dotted, therefore equality is not included. That is, the points (-3,1) and (3,3) do not belong to the region.

On the other hand, we observe that the point (0,0) does not enter the region either.

Finally, it is observed that the point (0,5) if it is located within the region.

Answer:

(0,5)

Suppose that the height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning.

kolbaska11 [484]

If the height of candle after 10 and 26 hours are 25 cm and 17 cm then the height of candle after 21 hours is 19.5 cm.

Given height of candle after 10 hours is 25 cm , height of candle after 26 hours is 17 cm.

We have to find the height of candle after 21 hours.

We have been given two points of linear function (10,25),(26,17).

We have to first form an equation which shows the height of candle after x hours.

let the hours be x and the height be y.

Equation from two points will be as under:

$(y-y_{1} )=(y_{2} -y_{1} )/(x_{2} -x_{1} )*(x- x_{1} )$

(y-25)=(17-25)/(26-10)* (x-10)

y-25=-8/16 *(x-10)

16(y-25)=-8(x-10)

16y-400=-8x+80

8x+16y=480

Now we have to put x=21 to find the height of candle after 21 years.

8*21+16y=480

168+16y=480

16y=480-168

16y=312

y=312/16

y=19.5

Hence the height of candle after 21 hours is 19.5 cm.

The radius of a clock face is 8.5 centimeters. What is the area of the clock face

hodyreva [135]

Answer:

Step-by-step explanation:

When finding the area of a circle you have to use the formula

Area= Pie x radius^2

Radius=8.5

So you have to plug that into the equation.

8.5x8.5=72.25

72.25x3.14=226.87

So Area is 226.87

So your answer is B
