Robert wants to buy a digital piano at a yard sale. He makes a scale drawing of his living

room. He uses a scale of 1 cm in the drawing

to 6 inches in the actual room. The width of the

digital piano is 54 inches. Will it fit along the

wall next to the bookshelf? Explain your answer.

please help!!

explain good and clearly:) I’ll give you brainliest!!

*see attachment for the drawing

No. The width is longer than the space available along the wall next to the bookshelf.

Step-by-step explanation:

The scale of the length of the space the piano is to occupy along the wall close to the bookshelf = 12 cm - 4 cm = 8 cm

Actual length of the space given a scale of 1 cm to 6 in: 6*8 = 48 in

The piano is said to have a width of 54 inches, therefore, it will not fit along the wall next to the bookshelf. The space available along the bookshelf is just only 48 inches long, which is less than the width of the piano.

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:
