Two numbers are co-prime if they have no common factors (other than
Triss [41]

Answer:

See below.

Step-by-step explanation:

a)

105/3 = 35

35/5 = 7

7/7 = 1

429/3 = 143

143/11 = 13

13/13 = 1

105 = 3 * 5 * 7

429 = 3 * 11 * 13

Not co-prime

For the other parts of the problem, do the same I did above. Find the prime factorizations of both numbers, and see if they have any prime factors in common.

HELP! A semi circle of radius 6 is centered at the origin as shown. A rectangle has two of its vertices at (5,0) and (-5,0) and
Ugo [173]

The Area of rectangle is "30 \ unit^2" and the equation of the semi circle is "y = \sqrt{36-x^2}".

According to the question,

The vertices of rectangle,

(5, 0) and (-5, 0)

Length,

l = 10 unit

Breadth,

b = 3 unit

Radius of semi circle,

r = 6

Centre of origin,

(0, 0)

As we know,

→ The Area of rectangle is:

= Length\times Breadth

= 10\times 3

= 30 \ unit^2

and,

→ The Equation of semi circle is,

y = \sqrt{r^2-x^2}

by substituting the values, we get

  =\sqrt{(6)^2-x^2}

  = \sqrt{36-x^2}

Thus the above is the correct answers.
