The answer is 1,000 4 or below you round down and 5 or higher you round up
R = sqrt 3 * (V /( pi * h))
V = 62.8
pi = 3.14
h = 15
now we sub
R = sqrt 3 * (62.8 / (3.14 * 15)
R = sqrt 3 * (62.6 / 47.1)
R = sqrt 3 * 1.33
R = sqrt 3.99
R = 1.9 rounds to 2 inches <===
= 12*5 + 12*3i - 5*2i - 6i^2 (remember that i^2 = -1) so:-
= 60 +26i - 6*(-1)
= 60 + 26i + 6
= 66 + 26i
Answer:
a⁻³⁵
Step-by-step explanation:
((a²)⁻²)⁵ ÷ (a⁴a)³
((a²)⁻²)⁵ ÷ (a⁴a¹)³
= (a⁻⁴)⁵ ÷ (a⁵)³
= a⁻²⁰ ÷ a¹⁵
= a⁻²⁰⁻¹⁵
= a⁻³⁵
Exponent rules:
Multiplying two numbers with same base: add exponents
Dividing two numbers with same base: subtract exponents
Number with exponent raised to another exponent: multiply the exponents together
