Today’s UV index is = 8

Erin will burn in = 15 minutes

Since, its given"The time it takes to burn without sunscreen multiplied by the SPF, or sun protection factor, is the time you can stay in the sun safely with sunscreen"

= 25\times15=375

So, Erin will be protected for 375 minutes.

For the given functions f and g find f•g and state it’s domain<br> f(x) = 3x - 6; g(x) = 8x +4
o-na [289]

f.g and its domain is 24x²-36x-24; all real numbers.

Given, f(x) = 3x - 6; g(x) = 8x +4.

We need to find the value of f.g

<h3>What is a domain?</h3>

The domain of a function; In mathematics, the domain of a function is the set of inputs accepted by the function.

Now, (f.g)(x)=(3x-6)(8x+4)

=24x²-48x+12x-24

=24x²-36x-24

Therefore, f.g and its domain is 24x²-36x-24; all real numbers.
