A dilation with a scale factor of 2 is applied to
liubo4ka [24]

The lengths of the three line segments after dilation is P'Q' = 4 \ cm, A'B'=3 \ cm and M'N'=6 \ cm

Explanation:

Given that the length of three line segments are PQ = 2 cm, AB = 1.5 cm and MN = 3 cm

Also, given that the dilation with a scale factor of 2 is applied to the three line segments.

We need to determine the length of line segments P'Q', A'B' and M'N'

Dilation means the transformation of the same shape with different size.

Since, it is given that the dilation with a scale factor of 2, we shall multiply each of the line segments with 2.

Thus, we have,

P'Q' = 2 \times 2 = 4 \ cm

A'B'=1.5 \times 2 = 3 \ cm

M'N'=3 \times 2= 6 \ cm

Thus, the lengths of the three line segments after dilation is P'Q' = 4 \ cm, A'B'=3 \ cm and M'N'=6 \ cm

What is 9.36•10~4 in standard form
marta [7]
With exponents of 10, the exponent really just tells you how many zeroes there are behind the 1. So, for example, 10^4=10000 (4 zeroes behind 1). When multiplying decimals by exponents of 10, you move the decimal to the right, and the amount of places is the exponent number. For example, if I multiply 5.34 by 10^2, I move the decimal over to the right 2 times and get 534.

So, if you just multiply these you get 9.36*10000, which is 93600.

1.) 70x/100x^2 = 7/10x

2.) 16x^3/24x = 2x^2/3

3.) 7x(2x+1)/21(2x+1) = x/3

4.) 35x - 35/x^2 - 1 =  35/x + 1

5.) x + 7/x^2 + 4x - 21 = 1/x - 3

6.) x^2 - 6x + 5 = x - 5/5

7.) x^2 - 36/x^2 - 3x - 18 = x + 6/x + 3

8.) x^2 - 3x - 10/x^2 + x - 2 = x - 5/x - 1
