When a figure is dilated, the corresponding angles created are always

vesna_86 [32]

When a figure is dilated, this means the corresponding sides of the shape is enlarged in a uniform multiple. In thsi case, the ratio of the sides remains the same. Thus, when ratio of the sides remains the same, the corresponding angles are also congruent in the dilated figure.

The gross federal debt y (in trillions of dollars) for a certain country in year x is approximated by the following equation,

miskamm [114]

Answer: 2008

Step-by-step explanation:

Given : The gross federal debt y (in trillions of dollars) for a certain country in year x is approximated by the equation $y =1.18x +1.58$ , where x is the number of years after 2000.

To find the year in which the federal debt will be $10.68 trillion, we substitute y= 10.68 in the above equation , we get

$10.68 =1.18x +1.58\\\\\Rightarrow\ 1.18x=10.68-1.58\\\\\Rightarrow\ 1.18x =9.1\\\\\Rightarrow\ x=\dfrac{9.1}{1.18}=7.7118644067\approx8$

The required year will be = 2000+8=2008.

Hence, in 2008 the federal debt will be $10.68 trillion.
