Find the value of 3sec2.4. (Round to the nearest tenth.)
again?
3 sec 2.4 = 3/cos 2.4
your calculator can surely do that.
Or google
or wolframalpha.com
And I had already done this for you here

To find the value of 3sec2.4, we first need to understand what "sec" means. "sec" is an abbreviation for the trigonometric function called "secant." The secant of an angle is the reciprocal of the cosine of that angle.
So, to find the value of 3sec2.4, we need to find the cosine of 2.4 and then take its reciprocal.
To do this, we can use a scientific calculator that has trigonometric functions. If you don't have a calculator, you can also use an online calculator or a trigonometric table.
Here's how you can do it step by step:
1. Start by finding the cosine of 2.4. On a scientific calculator, you can simply input 2.4 and press the cosine (cos) button. If you are using an online calculator, look for the cosine function and type in 2.4.
The cosine of 2.4 is approximately 0.737.
2. Next, take the reciprocal of the cosine value you just found. To do this, divide 1 by 0.737.
1 / 0.737 ≈ 1.357
3. Finally, multiply the reciprocal by 3 to get the value of 3sec2.4.
3 × 1.357 = 4.071
So, the value of 3sec2.4 is approximately 4.1 (rounded to the nearest tenth).
