the simplest way to evaluate is to substitute n = 1, 2, 3, 4 into the expression and sum the terms

= [(2 × 1) - 1 ] + [(2 × 2) - 1 ] + [(2 × 3) - 1] + [(2 × 4) - 1]

= 1 + 3 + 5 + 7 = 16

Are the fractions 3/9, 3/10, 3/11, and 3/12 in order from least to greatest

Cerrena [4.2K]

Answer:

The fractions $\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$ are not in order from least to greatest.

Step-by-step explanation:

Given order of fractions from least to greatest:

$\frac{3}{9},\frac{3}{10},\frac{3}{11},\frac{3}{12}$

To check if the fractions are in correct order.

Solution:

The fractions given have same numerators but different denominators.

For fractions the higher the denominator the lower is the value of that fraction.

Thus, in the given list the least value fraction will be the fraction with the greatest denominator which is $\frac{3}{12}$ and the greatest value fraction will be the fraction with the least denominator which is $\frac{3}{9}$

So, the order of the fractions from least to greatest is not correct. Instead the order is from greatest to least.

The correct order from least to greatest should be:

$\frac{3}{12},\frac{3}{11},\frac{3}{10},\frac{3}{9}$ .

Explain what the trigonometric reciprocals are ?

Softa [21]

Flipping over the trigonometric functions of sine, cosine and tangent we have the following respectively

1/cscФ (sinФ), 1/secФ (cosФ) and 1/cotФ (tanФ). These are the identities for which they numerically equal when the numerator and denominator of these fractions are swapped.
