Is the following relation a function? *

spayn [35]

Answer:

No.

Step-by-step explanation:

Well at first glance it might seem so but there are two points particularly that can tell you that these points cannot be within a function.

The points (3,2) and (3,-2) will yield an undefined slope (a straight vertical line). There is no possibility that the other points can be in this line (as their y - values are different) and there is no possibilty that this is a function at all according to the vertical line test (the test is that if you draw a vertical line that there shouldn't be more than one point on it).

The height of Mountain P is 1,086 feet.The height of Mountain Q is 4 times the height of Mountain P.The area model shown below r

earnstyle [38]

Answer:

A=4000, B=80, C=24

Step-by-step explanation:

You forgot to put the correct area model, I attached it to the answer.

We have the fact that Mountain Q is 4 times the height of Mountain P. That's the "4" we have in the left side of our model. It's like having a multiplication table, next to the "4" we have "A" and upper this we have "1000", the only thing we have to do is multiplify 4*1000=4000. The next letter we have is B and below it we have "320", we divided it by 4, 320/4=80. The last letter we have is C, and is below a "6", we only have to multiplify it by 4, 6*4=24.

At the end we only sum our

A + 320 + c = 4344 (4 times the height of Mountain P).
1000 + B + 6 = 1086(the height of the Mountain P).

Anna007 [38]

Answer:

336 ft²

Step-by-step explanation:

The rectangle is 13 ft long and 8 width that means we have two walls 8* 9 and two walls 13*9

Total walls area is

2*8*9 + 2*13*9 = 144 + 234 = 378 ft²

then we subtrac , areas of door, closet and windows

3 * 6.5 = 19,5 ft²

3 * 6,5 = 19,5 ft²

2 * 1,5 = 3 ft²

42 ft²

Then area to paint 378 - 42 = 336 ft²
