To send a standard letter through first-class mail, the cost depends on the weight of the letter. any letter one ounce or less will need $0.46 in postage. for each additional ounce over that, or any part of an ounce, the sender must add $0.20 more postage. create a graph showing the cost of mailing standard first-class letter weighing from 0 to one pound(16 ounces). explain how you know your graph is correct.

Let x represents the total weight of the parcel and f(x) represents the cost of the parcel,

Then, according to the question,

Any letter one ounce or less will need $0.46 in postage.

That is, For 0 < x ≤ 1, f(x) = 0.46

For each additional ounce over that, or any part of an ounce, the sender must add $0.20 more postage,

Also, the maximum weight = 16 ounces,

0.46 + 0.20 (x-1)= 16

⇒ 0.20 (x-1) = 15.54

⇒ x-1 = 77.7⇒ x = 78.7

Hence, the function that shows the cost of the letter having weight greater than 1 ounces is,

And, for 1 < x ≤ 78.7 f(x) = 0.46 + 0.20(x-1),

Thus, the complete function that shows the given situation is,

Thus, we get two line, y = 0.46 and y = 0.46 + 0.20(x-1),

Which are plotted in the below graph.

answer: 2 and 1

step-by-step explanation: got this question

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
