Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (6, 1280)(6,1280).
Phoenix [80]

Answer:

y=20(2)^x

Step-by-step explanation:

We want to write an exponential function that goes through the points (0, 20) and (6, 1280).

The standard exponential function is given by:

y=ab^x

The point (0, 20) tells us that <em>y</em> = 20 when <em>x</em> = 0. Hence:

20=a(b)^0

Simplify:

20=a(1)\Rightarrow a=20

So, our exponential function is now:

y=20(b)^x

Next, the point (6, 1280) tells us that <em>y</em> = 1280 when <em>x</em> = 6. Thus:

1280=20(b)^6

Solve for <em>b</em>. Divide both sides by 20:

64=b^6

Therefore:

b=\sqrt[6]{64}=2

Hence, our function is:

y=20(2)^x

How to find two different ways to find the new value after the original value is increased by 30%
maria [59]

The new value after the original value is increased by 30% is 1.3 times the original value.

<h3>Percentage</h3>

Percentage is used to express a fraction number or decimal in fraction of hundred. It is given by:

Percentage = [(new value - original value) / original value] * 100%

Let x represent the new value and y represent the original value, hence:

30% = [(x - y)/y] * 100%

0.3 = (x - y)/y

x - y = 0.3y

x = 1.3y

The new value after the original value is increased by 30% is 1.3 times the original value.
