Monique son just turned 2 years old and is 34 inches tall. Monique heard that the average boy will grow approximately 2 5/8 inches per year until the age of 15.

Part A: Write an equation that represents how old Monique son will be when he is 50 inches tall. ( let x represent the amount of year since age 2)

Part B: How old will Monique son be when he is 50 inches tall.

Answers

Answer:

The equation that represents the height as a function of the time is:

f(x) = 34 + 2.625x, where x represent the amount of year since age 2

We need to find x such that f(x) = 50 that is:

34 + 2.625x = 50

x = 6 years rounded to integer

6 years after the age of 2 is 2 + 6 = 8 years.

Monique's son will be 8 years old and 50 inches tall.

Congruent angles :

Two angles are said to be congruent if their corresponding sides and angles are of equal measure.

Two angles are also congruent if they coincide when superimposed.

From given figure, It is observed that transversal line m intersects pair of parallel lines l and k.

So that, corresponding angles , alternate angles and vertically opposite angles are equal.

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Scatter plot that shows the number of siblings 14 students have and each student's grade level.

Now,

The points on the scatter plot are like coordinates on a graph.

We see that,

The student in grade 2 has 4 siblings.

The student in grade 3 has 1 sibling.

The student in grade 4 has 2 siblings.

And so on.

Now,

There is no relationship between grade level and the number of siblings each student has.

This is true.

As grade level increases, the number of siblings each student has decreased.

This is not true.

As grade level increases, the number of siblings each student has stayed the same.

This is not true.

As grade level increases, the number of siblings each student has increased.

This is not true.

Thus,
