Answer:

{3}^{81} is bigger.

Step-by-step explanation:

{9}^{27}  = ( {3}^{2} )^{27}  =  {3}^{2 \times 27}  =  {3}^{54}  \\

If we compare the exponents of {3}^{54} and {3}^{81} it can be concluded that:

{3}^{81} > {3}^{54}

Mama L [17]
<span>Since the triangles are right triangles, the hypotenuse can be calculated using the Pythagorean theorem:
5²+12²=x²
x²=25+144, x²=169⇒x=√169
x=13
The hypotenuse of a smaller triangle is 13 units.</span>

Given A(-2,3), B(m, 5) and C(-1,0). Find the possible<br>values of m if AB = 2AC.​
babymother [125]

Answer:

m = 4 or m = -8

Step-by-step explanation:

length between 2 points = √(difference of x)² + (difference of y)²

AB² = (m - (-2))² + (5 - 3)² = (m + 2)² + 4 = m² + 4m +8

AC² = ((-1) - (-2))² + (0 - 3)² = 10

AB² = 4AC²

m² + 4m +8 = 40

m² + 4m - 32 = 0

(m - 4) (m + 8) = 0

m = 4 or m = -8

Naya [18.7K]

Answer: A. A tessellation that uses only one type of regular polygon

Step-by-step explanation:

When we cover a surface with a pattern of a flat geometric shapes such that there should have no overlaps or gaps, then the surface is called a tessellation.

A regular tessellation is tessellation made up by using nly one type of regular polygon. These are made up of entirely congruent regular polygons all that joining vertex to vertex

Hence, A is the correct option.
