The equation a2 + b2 = ca represents the relationship between the three sides of a right triangle.

choli [55]

Answer:

Step-by-step explanation:

I think you mean a² + b² = c², not ca.

a = 10, c = 26

b² = c² - a² = 26² - 10² = 576

b = √576 = 24 ft

The first term of a sequence is 2, the third term is 18, and the fifth term is 162. What is

Goshia [24]

Answer:

$a_2=6$

Step-by-step explanation:

Geometric sequence general formula: $a_n=ar^{n-1}$

Given:

$a_1=2$
$a_3=18$
$a_5=162$

Therefore,

$a_1=2 \implies a=2$

$a_3=2 \cdot r^2=18$

$a_5=2 \cdot r^4=162$

To find common ratio r, divide 5th and 3rd terms:

$\dfrac{a_5}{a_3}=\dfrac{2 \cdot r^4}{2 \cdot r^2}=\dfrac{162}{18}$

$\implies r^2=9$

$\implies r=\sqrt{9}=3$

Therefore, geometric sequence formula: $a_n=2 \cdot 9^{n-1}$

So second term of sequence:

$\implies a_2=2 \cdot 3^{2-1}=6$
