First you have to add all four of your numbers, 8.6+14.2+ -3.7+ 12=31.1. Then you divide your answer by 4, the number of numbers you added, and you get your answer of 7.775.

Not sure if i got this right?
aleksandrvk [35]

Answer:

The effect it will have on the volume is;

The volume will be 8 times larger

Step-by-step explanation:

The dimensions of the given prism are;

The length of the prism, l = 5 in.

The breadth of the prism, b = 5 in.

The slant height of the prism,  = 4 in. by 5 in.

The height of the prism, h = 7 in.

The shape of the prism = Parallelepiped

The volume of a parallelepiped = Area of Base × Height of the prism

The base area of the parallelepiped = The length × Breadth of the parallelepiped

∴ The base area of the given parallelepiped = 5 in. × 5 in. = 25 in.²

The volume of the given parallelepiped, V₁ is found as follows;

V₁ = 5 in. × 5 in. × 7 in. = 25 in.² × 7 in. = 175 in.³

When a scale factor of 2 in applied to the dimensions of the prism, we have;

The new volume, V₂ =  2 × 5 in. × 2 × 5 in. × 2 × 7 in.

∴ V₂ = 2 × 2 × 2 × 5 in. × 5 in. × 7 in. = 8 × 5 in. × 5 in. × 7 in. = 8 × V₁

Therefore;

V₂ = 8 × V₁

The volume of the image of the object, V₂ after applying a scale factor of 2 is 8 times larger than the volume of the object, V₁.

Lauren is reading a novel for English class. The data below shows the number of pages reads, y, in x hours.
strojnjashka [21]

Answer:

Choice B is correct

Step-by-step explanation:

The variable x represents the number of hours;

2, 4, 5, 7, 9

The least value is 2 while the maximum value is 9. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 10. Choice A is incorrect since the values 7 and 9 will not be accommodated in the graph.

The y variable represents the number of pages read;

50, 100, 125, 175, 225

The least value is 50 while the maximum value is 225. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 250. Both choices C and D are incorrect since none of the values will be accommodated in the graph.

1) 3 (x - y)² - 10 (x-y) + 8​
katovenus [111]

Answer:

(3x-3y-4)(x-y-2)

Step-by-step explanation:

Given expression:

3(x-y)^2-10(x-y)+8

Let u = (x - y):

\implies 3u^2-10u+8

To factor a quadratic in the form  ax^2+bx+c  find two numbers that multiply to ac and sum to b:

\implies ac=3 \cdot 8=24

\implies b=-10

Therefore, the numbers are: -6 and -4.

Rewrite b as the sum of these two numbers:

\implies 3u^2-6u-4u+8

Factor the first two terms and the last two terms separately:

\implies 3u(u-2)-4(u-2)

Factor out the common term (u - 2):

\implies (3u-4)(u-2)

Substitute back in u = (x - y):

\implies (3(x-y)-4)((x-y)-2)

Simplify:

\implies (3x-3y-4)(x-y-2)

Factorise the following, using the identity a2 – 2ab + b2 = (a – b)2
Rasek [7]

The factorisation of the given expressions is as follows;

  • a) p²y²– 2py + 1 = (py -1)²
  • b) a²y² -2aby +b² = (ay - b)²

<h3>Factorization using identities</h3>

The given identity is;

  • a²– 2ab + b² = (a – b)²

From the given identity, we can conclude that;

In the expression (a);

  • py represents a in the identity and 1 represents b in the identity.

In the expression (b);

  • ay represents a in the identity and b represents b in the identity.

Hence, the factorised expressions are as represented above.
