Mathematics

Answer:

A ≈ 269.81 cm²

Step-by-step explanation:

This shape is a hexagon (it has 6 sides) so let's use the formula for the area of a hexagon.

A = \frac{3\sqrt{3} }{2} s^{2}

Where s is the length of the sides

Substitute:

A = \frac{3\sqrt{3} }{2} s^{2}

A = \frac{3\sqrt{3} }{2} 10^{2}

Solve:

A = \frac{3\sqrt{3} }{2} 10^{2}

A = \frac{3\sqrt{3} }{2} 100

Multiply the numerator:

A = \frac{3\sqrt{3} }{2} 100

A ≈ \frac{5.12 }{2} 100

(The numerator reflects a rounded number, but the actual calculations are exact)

Divide the fraction:

A ≈ \frac{5.12 }{2} 100

A ≈ 2.6(100)

Multiply:

A ≈ 2.6(100)

A ≈ 269.81 cm²

Therefore, the area is approximately 269.82 cubic centimeters.

Mike is overdrawn at the bank by $18. His sister has $23 more than him. How much does
alexandr402 [8]

Answer:

$41?

Step-by-step explanation:

Well, if he's overdrawn, then he doesn't have any money, he owes money. But I'm assuming they want to add. The sister has $23 more than he does, so add.

18+23=41.

So his sister has $41.

What are the coordinates of point P on the directed line segment from A to B such that P is One-fourth the length of the line se
Anna35 [415]

The coordinates of the point P on the directed <em>line</em> segment from A to B such that P is one-fourth the length of the <em>line</em> segment is P(x, y) = (- 2.75, - 0.5). (Right choice: C)

<h3>How to determine the coordinates of a point within a line segment</h3>

By geometry we remind that a <em>line</em> segment can be constructed from two distinct points on a plane. By linear algebra we can obtain an equation to determine the coordinates of a point within a <em>line</em> segment:

\vec P = \vec A + k \cdot \overrightarrow{AB}     (1)

Where:

  • \vec A - Coordinates of the point A.
  • \vec P - Coordinates of the point P.
  • \overrightarrow {AB} - Vectors between points A and B.
  • k - Length factor

If we know that A(x, y) = (- 5, - 1), B(x, y) = (4, 1) and k = 0.25, then the coordinates of the point P are:

P(x, y) = (- 5, - 1) + 0.25 · [(4, 1) - (- 5, - 1)]

P(x, y) = (- 5, - 1) + 0.25 · (9, 2)

P(x, y) = (- 5, - 1) + (2.25, 0.5)

P(x, y) = (- 2.75, - 0.5)

The coordinates of the point P on the directed <em>line</em> segment from A to B such that P is one-fourth the length of the <em>line</em> segment is P(x, y) = (- 2.75, - 0.5). (Right choice: C)
