Given:
f(x) = 2x^{2} +5 \sqrt{x-2}

Asked:
f(3)

Solution:
Subtitute x with 3 in the function
f(x) = 2x^{2} +5 \sqrt{x-2}
f(3) = 2(3)^{2} +5 \sqrt{3-2}

Then simplify to find the value of f(3)
f(x) = 2(9) +5 \sqrt{1}
f(x) = 18 +5
f(x) = 23

The final answer is 23

Question 19 Unsaved
nata0808 [166]

A response variable you are trying to measure once you've done the experiment.

What have you done? You've measured what sunglasses will do to affect eyesight. You have used a 10 week period to measure their response. You don't really care what the response is -- only if there is one.

10 people and 10 weeks don't change. Those two are not a choice for an answer. Now you come to the crunch of the question. Is it the sunglasses you are trying to measure or is it what your eyes have done because you were wearing sun glasses.

So we need an answer. If you say sun glasses, how did you measure what they did. THAT's the answer. The answer is not the sunglasses.

Lynna [10]
Since 50% are ripe, and you know that 25% are ripe apples, you also can assume 5% of apples aren’t ripe. From that you know that 50% + 5% is ripe oranges, and apples. So 45% are not ripe oranges
