Why does the poet use a similar<br> phrase at the beginning of each<br> stanza?

kobusy [5.1K]

Answer:

This repeating phrase increases the lyricism of the poem, that is, it makes an appealing sound to our ears. Because the phrase has a special rhythm, called dactylic, it is especially pleasing. This same rhythm is repeated in each stanza, lending cohesion to the poem, helping it hold together as a unit.

Given isosceles trapezoid TRHY, in units what is the length of b2 if the height is 13 units, b1 is 21 units, and the area is 215

GenaCL600 [577]

We are given a trapezoid TRHY.

Height of the trapezoid = 13 units.

b1 = 21 units and

Area = 215 units squares.

We need to find the length of b2.

We know formula for area of a trapezoid.

$A= \frac{1}{2} (b1+b2)\times h$

Plugging values in formula.

215 = $\frac{1}{2}$ (21+b2)× 13.

215 = 6.5(21+b2)

Dividing both sides by 6.5, we get

$\frac{215}{6.5}=\frac{6.5(21+b2)}{6.5}$

33.08 = 21+b2.

Subtracting 21 from both sides, we get

33.08-21 = 21-21+b2

b2 = 12.08.

<h3>Therefore, length of b2 is 12.08 units.</h3>

Sorting Quadratic Function Discriminants

nataly862011 [7]

The number of zeros of the quadratic functions, considering their discriminant, is given as follows:

discriminant = 0: 1 Real number solution.

discriminant = -36: 0 Real number solutions.

discriminant = 3: 2 Real number solutions.

discriminant = 2: 2 Real number solutions.

discriminant = 100: 2 Real number solutions.

discriminant = -4: 0 Real number solutions.

<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>

A quadratic equation is modeled by:

$y = ax^2 + bx + c$

The discriminant is:

$\Delta = b^2 - 4ac$

The solutions are as follows:

If $\mathbf{\Delta > 0}$ , it has 2 real solutions.

If $\mathbf{\Delta = 0}$ , it has 1 real solutions.

If $\mathbf{\Delta < 0}$ , it has 0 real solutions.

Hence, for the given values of the discriminant, we have that:

discriminant = 0: 1 Real number solution.

discriminant = -36: 0 Real number solutions.

discriminant = 3: 2 Real number solutions.

discriminant = 2: 2 Real number solutions.

discriminant = 100: 2 Real number solutions.

discriminant = -4: 0 Real number solutions.
