Step-by-step explanation:
Answer:
113.04 km²
Step-by-step explanation:
Formula - Area = πr²
= 3.14 * 6²
= 113.04 km²
Power of power rule:
Zero-Exponent Rule: a0 = 1, this says that anything raised to the zero power is 1. Power Rule (Powers to Powers): (am)n = amn, this says that to raise a power to a power you need to multiply the exponents. ... Only move the negative exponents.
Power of product rule:
The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. ... Adding the exponents is just a short cut! Power Rule. The "power rule" tells us that to raise a power to a power, just multiply the exponents.
i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.
Then you would get 4x²-4x-8.
You then cannot simplify further. so your answer would be 4x²-4x-8.
Half-life = [elapsed time * log (2)] / [log (begng amt / endg amt)]
half-life = (3 days * 0.30102999566) / log (1 / .58)
