<h2>
19.596 feet</h2>
Step-by-step explanation:
Use the pythagorean theorem.
a^2 + b^2 = c^2
a = 20ft
c = 28ft
400 + b^2 = 784
b^2 = 384
b = 19.596
Answer:
14
Step-by-step explanation:
Arithmetic expressions are best evaluated using a reliable calculator. The Google calculator always follows the Order of Operations, so can give you a good answer to such questions.
(1/4)^-2 - (5^0)(2)(1^-1)
= 16 - (1)(2)(1) . . . . evaluate the exponents first
= 16 -2 . . . . . . . . . evaluate the product next
= 14 . . . . . . . . . . . finally, evaluate the sum
___
The rule of exponents is ...
a^-b = 1/(a^b)
