to halp you and thank you
Algebraic equation:
2x + 5 = 39
x = 17
We are provided with the following
And we need to find <em>f(1)</em> and then choose the choose the equivalent expression for <em>f(1)</em> from the given options . But , as <em>two functions</em> are defined by <em>f(x)</em> so let's define the function for x = 1
As f(x) = x , for <em>x < 2</em> and <em>1 < 2</em> . So <em>f(x) = x for x = 1</em> , now putting x as 1 ,so <em> f(1) = 1</em>
Now , also , as in all option their is <em>f(2)</em> , so let's find <em>f(2) also </em>, so that we can easily find the correct option , now as <em>f(x) = 2x - 3 , for x ≥ 2</em> and 2 = 2 , so <em>f(2) = 2(2) - 3 = 4 - 3 = 1 </em>
Now , As other options contains some constant multiplied by <em>f(2)</em> except option C) , so only f(2) will be 1 , and <em>also f(1) = 1</em> , So f(1) = f(2)
<em>Hence , Option C) f(2) is correct</em>
Answer:
- (1/4)(12π)
- (0.25)(12)(3.14)
- 3π
- 9.42
Step-by-step explanation:
1/4 of 12π can be written several ways. All of the answer choices are equivalent except the second one.
- (1/4)(12π)
- (0.25)(12)(3.14)
- 3π
- 9.42
All of these are equivalent ways to write the measure of 1/4 of 12π.
