Which description is represented by a discrete graph? a. kiley bought a platter for $19 and several matching bowls that were $8 each. what is the total cost before tax? b. the temperature at 9 a. m. was 83° f and is heating up at an average rate of 6°f per hour. what is the temperature x hours later? c. juan ate an egg with 78 calories and some cereal with 110 calories per serving for breakfast. what is the total amount of calories he consumed? d. a bottle contained 2,000 ml of liquid and is being poured out at an average rate of 300 ml per second. how much liquid is left in the bottle after x seconds?

Answer : A and D can be  represented by a discrete graph.

A discrete graph is a series of countable unconnected points with

domain→ a set of input values including all numbers in an interval.

A. This description can be represented by a discrete graph because we can count the number of bowls Kiley bought.  ∴ it's not continuous.

B. This description cannot be represented by a discrete graph because it will gently get hotter with time. The temperature can be in decimal form.∴This description is said to be continuous not discrete.

C. This description can be represented by a discrete graph because there Juan ate 78 calories and 110 calories,∴ the total amount of calories he consumed= 188 calories. After that there is no other input ,so it is countable and is discrete.

D. This description cannot be represented by a discrete graph ∵this is continuous as with respect to time liquid is being poured out so we cannot count liquid ∴ this is not discrete.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
