Can anyone help me out with this

The correct answer is:

Focal point.

Explanation:

The focal point of a lens is the point in space where parallel light rays meet after they pass through the lens. A perfect" lens sends all light rays through one focal point, which result in the clearest image.

Final answer:

The ratio of 2/11 to 7/11 simplified as a fraction in the lowest terms is 2/7. This was done by canceling out the like terms in both fractions, essentially dividing both numbers in the ratio by the common factor of 11.

Explanation:

To write the ratio 2/11 to 7/11 as a fraction in the lowestterms, you are essentially finding the ratio of these two fractions. Starting from the fractions 2/11 and 7/11, we 'cancel out' the like terms in both fractions. Remember, a ratio is simply a way of comparing two or more numbers. So the ratio of 2/11 to 7/11 simplifies to:

2/11 : 7/11 = 2/7

So, the ratio 2/11 to 7/11 as a fraction in the lowest terms is 2/7. This was achieved by dividing both numbers in the ratio by the common factor of 11.

Answer:

E, 3.

Step-by-step explanation:

Since both f(x) and g[f(x)] are quadratic polynomials, g(x) must also be a linear polynomial.

Let g(x) = Ax + B, where A and B are constants to be determined.

Then we have A[2x² - 3x + 1] + B ≡ x² - (3/2)x + 3.

=> A = 1/2 and B = 5/2.

Hence, f[g(-1)] = f[(1/2)(-1) + (5/2)] = f(2) = 2(2)² - 3(2) + 1 = 3. (E)
