Answer:

A. x = 7; y = 27

As the system told that my answer contains inappropriate words but I cannot figure out which one, so that I would attach my answer in the image attached.

Can someone help me find the domain and range of this graph?​
arlik [135]

Answer:

Domain: (-5, 6]

Range: [-3, 6]

Step-by-step explanation:

Domain is all x-values that can be inputted into function f(x).

Range is all the y-values outputted by function f(x) when we plug in <em>x</em>.

We see that our x-values span from -5 to 6. Since -5 is a open dot, we cannot input -5. Therefore, we have:

Domain: (-5, 6]

Parenthesis on -5 shows that it is not included and bracket on 6 shows it is included.

We see that our y-values span from -3 to 6. Since both points are closed dots, we can include both. Therefore, we have:

Range: [-3, 6]

Brackets on both numbers signify that both values are included in the graph.

Please help me I’ve been stuck for hours
wlad13 [49]

Answer/Step-by-step explanation:

Given that a and b are two corresponding sides of two similar figures, it follows that the ratio of their areas = a²/b².

We would use the above knowledge to solve the questions given as follows:

✔️The first pair similar of shapes:

Missing area = x cm²

Therefore,

x/9 = 8²/4²

x/9 = 64/16

x/9 = 4

Cross multiply

x = 4 × 9

x = 36 cm²

✔️The second pair similar of shapes:

Missing area = x cm²

Therefore,

x/240 = 8²/32²

x/240 = 64/1,024

Cross multiply

x*1,024 = 64*240

x*1,024 = 15,360

Divide both sides by 1,024

x = 15,360/1,024

x = 15 cm²

✔️The third pair similar of shapes:

Missing area = x cm²

Therefore,

x/40 = 3²/2²

x/40 = 9/4

Cross multiply

x*4 = 9*40

x*4 = 360

Divide both sides by 4

x = 360/4

x = 90 cm²

Please help! Will Mark brainliest if correct!!
Alina [70]

Answer:

The new volume will be 3 3/8 or maybe 27/8 of its original volume.

Step-by-step explanation:

Cone Volume = PI * radius^2 * height / 3

So if radius = 1 and height = 1 then volume = 1.0472

When radius = 3 and height = .375 then volume = 3.5343

Volume increases by 3.5343 / 1.0472 = 3 and 3/8
