Eight year-old Alex is learning to ride a
cestrela7 [59]

Answer:

The age of the horse, in human years, when Alex was born can be determined by simply deducting the Current age of Alex from the Current age of the horse in human years.

Therefore, the age of the horse, in human years, when Alex was born was 42 years.

Step-by-step explanation:

Current age of Alex = 8

Current age of the horse in human years = 50

Since the age of the horse is already stated in human years, it implies there is no need to convert the age of the horse again.

Therefore, since Alex is a human who was born 8 years ago, the age of the horse, in human years, when Alex was born can be determined by simply deducting the Current age of Alex from the Current age of the horse in human years as follows:

The age of the horse, in human years, when Alex was born = 50 - 8 = 42

Therefore, the age of the horse, in human years, when Alex was born was 42 years.

This can be presented in a table as follows:

                               Age of Alex        Age of the Horse (in human years)

Eight years ago              0                                           42

Current age                    8                                           50

Evaluate y=x squared minus 2x plus one for 3i
pychu [463]

Answer:

- 8 - 6i

Step-by-step explanation:

The given expresion is

y =  {x}^{2}  - 2x + 1

We want to evaluate this expression when x=3i

We substitute to obtain:

y =  {(3i)}^{2}  - 2(3i) + 1

We simplify to get

y =  {3}^{2}  \times  {i}^{2}  - 6i + 1

Recall that

{i}^{2}  =  - 1

This implies that:

y = 9 \times  - 1 - 6i + 1

y =  - 9 - 6i + 1

y =  - 8 - 6i
