This is Pythagorean theorem. 
We already know a and c. 
a = 4 and c = 10
4² + b² = 10² 
16 + b² = 100 
Subtact 16 from each side. 
b² = 84 
Square root of each side: 
b = ≈9.165 or √84

Hope this helps!

What is the sum of the series?
lana66690 [7]

Answer:

44

Step-by-step explanation:

substitute k = 1, 2, 3, 4 into 2k² - 4 and sum the terms

k = 1 : 2(1)² - 4 = 2 - 4 = - 2

k = 2 : 2(2)² - 4 = 8 - 4 = 4

k = 3 : 2(3)² - 4 = 18 - 4 = 14

k = 4 : 2(4)² - 4 = 32 - 4 = 28

sum = - 2 + 4 + 14 + 28 = 44
