Jack is 12 and his sister Sophia is 16. Jack says that the relationship between his age and Sophia‘s is proportional and the con

n200080 [17]

Given that current age of Jack = 12 years

Given that current age of Sophia = 16 years

Jack says that the relationship between his age and Sophia‘s is proportional

If Jack's age is represented by y and Sophia's age by x then we can write y=kx as they are in proportion

where k is called constant of proportion

Now let's plug given ages of each that is y=12 and x=16 into y=kx to find the constant of proportionality

12=k*16

12/16=k

Which is same as the given value of constant of proportionality.

Hence Jack is right about his statement.

But if you think about practical life situation then age of both will not be in proportion

For example after 1 year Jack's age will be 13 and Sophiy's age will be 17

then constant of proportionality using new values will be 13/17

Clearly 12/16 and 13/17 are not same.

So in practical life, age of both will not in in proportion.

If the coefficient a in the general quadratic equation is equal to 9, what is the focal length for the

lutik1710 [3]

Answer:

Step-by-step explanation:

Let the equation of a parabola be

$y^{2}$ = 4ax.

Then , focal length of the parabola is a.

As , (0,0) is the vertex and its focus is (a,0)

Thus, focal length comes out to be a.

Here,

a is given as 9 units .

Thus focal length of the parabola, d, equals to 9 units

At the gym, Tika spends twice as much time doing aerobics than weight training. She stretches for one fifth of the time she spen

Dafna1 [17]

Answer:

Her total workout is $2w+w+\frac{w}{5}$ .

Step-by-step explanation:

Consider the provided information.

Let w be the amount of time Tika spends on weight training.

Tika spends twice as much time doing aerobics than weight training.

It means she spends $2w$ time doing aerobics.

She stretches for one-fifth of the time she spends on weight training.

It means she spends $\frac{w}{5}$ time for stretches.

The total workout time is:

$2w+w+\frac{w}{5}$

Hence, her total workout is $2w+w+\frac{w}{5}$ .
