Answer:

The graph in the bottom right (The circle) is not a function

Step-by-step explanation:

As the circle has multiple y values for each x value, it is not a function. In other words, that graph fails the vertical line test.

Answer:

IV graph

Step-by-step explanation:

Function: It is relation between x and y.For each x, there is  a unique value of y.

Only one output for one input.

One value of x cannot have more than one images.

Vertical line test:

When we draw a vertical line passing through any given  value of x and cut the curve more than one  points then, the curve does not represents the function.

When a vertical line cuts the curve at one point then, the curve represents the function.

In I graph, We can see that

Image of 1 is 2.

Image of 2 is 1.

Image of -2 is 1.

There is only one output for input.

Hence, it represents the function.

In II graph,

By vertical line test, when we draw a vertical line x=1 then it cuts the graph at one point only.

Hence, it represents the function.

In III graph,

Image of 1 is 1.

Image of 0 is 2.

Image of -1 is 3.

Image of -2 is 4.

There is only one output for 1 input.

Hence, it represents the function.

In IV graph,

When we draw a vertical line x=1 then , it cuts the curve at two points.

Therefore, given circle does not represents the function.

(1 point) 1. The height (in feet) and volume of usable lumber (in cubic feet) of 32 cherry trees are measured by a researcher. T
Thepotemich [5.8K]

Answer:

C. volume

Step-by-step explanation:

The response variable in this scenario would be the volume of the usable lumber. That is because this variable depends completely on the height of the cherry trees that are being measured. The higher that the cherry trees are the more volume can be expected to get from cutting these trees down. The opposite goes for trees that are smaller, they would decrease the total expected volume that will be received from the usable lumber since there would be less amount of tree to cut down.

Consider the diagram below. Which of the following represent the values of x,y, and z to the nearest hundredth?
astraxan [27]
See the attached figure to better understand the problem

we know that
in the triangle BCD
y²+5.66²=z²-------> y²=z²-5.66²------> equation 1

in the triangle ABC
y²+5.66²=x²-------> y²=x²-5.66²------> equation 2

equals 1 and 2

z²-5.66²=x²-5.66²--------> z²=x²---------> z=x

if z=x then
angle A=45°
angle D=45°

in the triangle ABD
cos 45=z/(5.66*2)-------> z=11.32*cos 45-----> 11.32*√2/2----> 8
z=8
x=8

y²=z²-5.66²------> 8²-5.66²-----> y²=31.96------> y=5.65

the answer is
the value of x is 8
the value of z is 8
the value of y=5.65

Airida [17]

ANSWER

Area = 2\sqrt{3}  \:  {cm}^{2}

EXPLANATION

We need to use the Pythagoras Theorem to find the height of the triangle.

{a}^{2}  +  {b}^{2}  =  {c}^{2}

({2 \sqrt{3}) }^{2}  +  {b}^{2}  =  {4}^{2}

12 +  {b}^{2}  = 16

{b}^{2}  = 16 - 12

{b}^{2}  = 4

Take positive square root to get;

b =  \sqrt{4}  = 2

Area =½bh

Area =  \frac{1}{2}  \times  2\sqrt{3}  \times 2

Area = 2\sqrt{3}  \:  {cm}^{2}
