Work out the value of y when x = 4 30 points

y = 54/25 when x = 4.

Step-by-step explanation:

y is given by the equation:

Where p and q are numbers.

We are also given that when x = 1, y = 10 and when x = 6, y = 0.7776.

And we want to determine the value of y when x = 4.

Since y = 10 when x = 1:

Simplify:

Any number (except for zero) to the zeroth power is one. Hence:

Thus, our equation is now:

When x = 6, y = 0.7776. Thus:

Simplify and divide both sides by ten:

Take the fifth root of both sides:

Use a calculator. Hence:

Our completed equation is:

Then when x = 4, y equals:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
