A pattern exists among the units digit of the posers of 8 as shown in the diagram.
guajiro [1.7K]

Answer:

B) 4

Step-by-step explanation:

We can solve this by observing some pattern.

The powers ending in 4 as unit digit are:

{8}^{2} , {8}^{6} , {8}^{10} , {8}^{14} , {8}^{20} ,...

The exponents form the sequence:

2,6,10,14,20,...

We need to check if 62 belongs to this sequence.

This is an arithmetic sequence with a common difference of 4 and a first term of 2.

The explicit formula is

2 + 4(n - 1)

We equate this to 62 and solve for n.

2 + 4(n - 1) = 62 \\ 4(n - 1) = 60 \\ n - 1 = 15 \\ n = 16

Since n is a natural number, 62 belongs to the sequence.

Hence

{8}^{62}

will have a unit digit of 4.

How many triangles are there that satisfy the conditions a =13, b =9, A = 62°?
8_murik_8 [283]

Answer:

Step-by-step explanation:

Alright, lets get started.

Using sin Law,

\frac{sinA}{a}=\frac{sinB}{b}

Plugging the value of a, b and angle A

\frac{sin62}{13}=\frac{sinB}{9}

sinB=\frac{9*sin62}{13}

sinB=\frac{9*0.8829}{13}

sinB=0.61127

taking sin inverse on both sides

B=sin^{-1}(0.61127) =37.68

The may be another value of B that will called B' = 180-37.68=142.32

We will not consider this B' value because the um of angle B' and A will exceeds 180 degree (142.32+62=204.32)

Thats why only one triangle is possible.   :   Answer

Hope it will help :)

What is the measure of each exterior angle of the right triangle?<br> x = <br> y = <br> z =
Nuetrik [128]

Answer:

x = 90

y = 134

z = 136

Step-by-step explanation:

Sum of interior angles of a triangle are 180

Linear angles are 180

So 180 - 90 = 90

180 - 44 = 136

180 - 90-44 = 46

180 - 46 = 134
