Step-by-step explanation:It jusyt is
Based on the fact that Kayden is the youngest and their ages are consecutive and add up to 90, the Kayden is 21.
<h3>How old is Kayden?</h3>
To find Kayden's age, assume that it is x and use the formula:
90 = x + (x + 1) + (x +2) + (x +3)
Solving for x gives:
90 = 4x + 6
4x = 90 - 6
x = 84 / 4
x = 21

So, after 3 months, $18.55 in interest is earned.
Using implicit differentiation, it is found that y is changing at a rate of 10 units per second.
---------------------
The equation is:

Applying implicit differentiation in function of t, we have that:

- x-values changing at a rate of 2 units per second means that

- Point Q(1,4) means that
.
We want to find
, thus:


y is changing at a rate of 10 units per second.
