Which relation is a function of x?
Ivahew [28]

Answer:

The last choice, the graph.

Step-by-step explanation:

The 4 relations are:

A.

A set of ordered pairs.

This is not a function because 2 ordered pairs have the same x-coordinate, 1.

B.

Table.

All ordered pairs have 0 as the x-coordinate. Since the same x-coordinate appears more than once, it is not a function.

C.

x = 3y^2 - 7

This is a function of y, and it is a horizontal parabola, so it does not pass the vertical line test. It is not a function.

D.

The graph.

This is a function because it passes the vertical line test.

Answer: The last choice, the graph.

1. in the figure FL=5 and HL= 8 what is FM (hint Pythagorean theorem and radi of circles)
marta [7]
1- FM is 3

we know that FM and FG are radius of the circle. so:
FM =FG


so if we find FG by Pythagorean theorem, we find FM, too


FL (hypotenuse) is 5

HL is 8. GL is half of HL. so GL is 4

now we can use Pythagorean theorem to find FG
4 {}^{2}  +  {x}^{2} =  {5}^{2}    \\  {x}^{2}  =  {5}^{2}  -  {4}^{2}  \\  {x}^{2}  = 25 - 16 = 9 \\ x =  \sqrt{9}  = 3




2- x is 40


BAD is half of m DB

ADB is half of m AB


so BAD is 50

and ADB is 90


Then ABD will be:
180 - (50 + 90) = 180 - 140  \\ = 40



good luck

On an architect's drawing, the scale is 1 inch equals 6.5 feet. The distance on the drawing of the width of the dining room is 3
Radda [10]

Answer:

22.75

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

3.5 x 6.5 = 22.75 ft
