SSSSS [86.1K]
1) Quaterly interes = 3% / 4 = 0.03 / 4

2) Values:

after 1 quarter: 2000 (1 + 0.03/4)

after 2 quarters: 2000 (1 + 0.03/4)^2

after 3 quarters: 2000 (1 + 0.03/40^4

after 4 quarters = 2000 (1 + 0.03/4)^4

You could have used the future value formula directly:

A = C * (1 + r/n) ^ n*t

where r = 3% = 0.03

n = number of periods in a year: 4

t = number of years = 1

C = initial investment = 20000

=> A = 2000 (1 + 0.03/4)^4

Answer: option D. A = 2000 ( 1 + 0.03 /4) 4

Triangle XYZ is translated by the rule (x + 1, y â 1) and then dilated by a scale factor of 4 centered at the origin. Which stat
marysya [2.9K]

Answer:  Y and Y'' are congruent after the translation, but not after the dilation.

Step-by-step explanation:

We know that we generally prefer rigid transformations if want to create congruent images.

There are three basic kinds of rigid transformations:  

1) rotation 2) reflection 3) translation

So, they all create congruent images.

But a dilation does not create congruent images because it creates an image of similar same shape as the original but not the same size.

Given : Triangle XYZ is translated and then dilated by a scale factor of 4 centered at the origin.

Then, the correct option is "Y and Y'' are congruent after the translation, but not after the dilation."
