How can transformations show that two images are congruent?

Mathematics
1 answer:
s2008m [1.1K]3 years ago
8 0

Step-by-step explanation:

Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

I hope it's helpful!

A certain computer loses half of its value every two years. If the value of the computer after 3 years is 425, what was the init
IrinaVladis [17]

Answer:

1,700      

Step-by-step explanation:

The computation of the initial value of the computer is shown below:

Let us assume the value of a certain computer in the first year is X

In the second year, it is \frac{X}{2}

In the third year, it is \frac{X}{2}

In the fourth year, it is \frac{X}{4}

Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

\frac{X}{4} = 425

So, X = 1,700

Hence, the initial value of the computer is 1,700

Need help with number 6 and how did you get it
Soloha48 [4]
A rectangular prism is just a shape that looks like a brick.

If you think about a brick for a few seconds, you'll realize
that it has

-- 2 faces of  (length by width)
-- 2 faces of  (length by height)
and
-- 2 faces of  (width by height).

The dimensions of the brick in question 6 are 8ft, 3ft, and 5ft.
So it has

-- 2 faces of  8ft  by  3ft
-- 2 faces of  8ft  by  5ft
and
-- 2 faces of  3ft  by  5ft .

Can you take over and complete it now ?

PLLLZ HELP Find Sn if a1 = 20, d = –10, and n = 25.
Ivanshal [37]

Option A: -2500 is the value of S_{25

Explanation:

It is given that the first term is a_1=20

The common difference is d=-10

We need to determine the sum of 25 terms.

The sum of  terms of an arithmetic series can be determined using the formula, S_n=\frac{n[2a_1+(n-1)d]}{2}

Substituting n=25 , a_1=20 and d=-10

Thus, we have,

S_{25}=\frac{25[2(20)+(25-1)(-10)]}{2}

Simplifying the values, we get,

S_{25}=\frac{25[40+(24)(-10)]}{2}

S_{25}=\frac{25[40-240]}{2}

Subtracting the terms within the bracket, we get,

S_{25}=\frac{25[-200]}{2}

Multiplying the terms in the numerator, we have,

S_{25}=\frac{-5000}{2}

Dividing, we get,

S_{25}=-2500

Thus, the sum of the 25 terms is -2500

Therefore, Option A is the correct answer.
