10! = 10 × 9! = 10 × 362880

  = 3628800

_____

A number is multiplied by 10 by shifting the decimal point one place to the right. Here, that means appending a place-holder zero to the number.

Find the perimeter and the area of the polygon with the given vertices.
7nadin3 [17]
Answer:
Area : 45 Perimeter : 2,025

Explanation:
Area: 5 times 9 equals 45. The 5 is the polygon’s base, the 9 is the polygon’s height.
Perimeter: 5 times 5 times 9 times 9 equals 2,025. Perimeter is base times base times height times height.

seropon [69]

Answer:

  888.89 km

Step-by-step explanation:

Write the given question as an equation and solve.

  80 km = 0.09 × (what distance)

  (80 km)/0.09 = what distance . . . . . divide by the coefficient of the variable

  888.89 km ≈ what distance

80 km is 9% of 888.89 km

Answer:

1. In number theory, Euclid's lemma is a lemma that captures a fundamental property of prime numbers, namely: Euclid's lemma — If a prime p divides the product ab of two integers a and b, then p must divide at least one of those integers a and b.

2. The Thales theorem states that: If three points A, B, and C lie on the circumference of a circle, whereby the line AC is the diameter of the circle, then the angle ∠ABC is a right angle (90°).

Answer:

  D.  A triangle with angles measuring 75°, 60°, and 45°​

Step-by-step explanation:

Given various triangle descriptions, you want to know which one describes more than one triangle.

<h3>Triangle relations</h3>

The angles and sides of a triangle satisfy a few different relations:

  • angle sum — the sum of angles is 180°
  • triangle inequality — the sum of the two short sides exceeds the long side
  • law of cosines — c² = a² +b² -2ab·cos(C)
  • law of sines — a/sin(A) = b/sin(B) = c/sin(C)

<h3>Application</h3>

A. Two sides and the included angle can be used with the Law of Cosines to find the length of the third side. That is, a single triangle is created by these measurements.

B. Sides measuring 4, 8, and 15 do not satisfy the triangle inequality, so no triangle is created by these measurements.

C. Sides measuring 6, 8, and 10 satisfy the triangle inequality, so will create a single triangle. (That triangle is a right triangle.)

D. The given angles total 180°, so could be the angle measures of any number of triangles. At least one side length must be specified in order to completely define a single triangle. These measures create more than one triangle.
