Answer:
x = −
7
Step-by-step explanation:
y = 4.5*x^2-9*x+8.5;4.5;-9;8.5
-(((-9)^2-(4*4.5*8.5))/(4*4.5))
-(-9/(2*4.5))
4.5*0^2-(0*9)+8.5
(7*x^5-(5*x^7))^(1/2)+1/((7*x^5-(5*x^7))^(1/2))
Answer:
Step-by-step explanation:
<u>Step 1</u>
- s = 3 terms x 6 years, s = 18 years
<u>Step 2</u>
- h = 30 years - 18 years, h = 12 years
<u>Step 3</u>
- t = 12 years ÷ 2 years, t = 6 terms
No because 101 is prime. Square roots of primes are always irrational. If they weren't, you could write sqrt(101) as some a/b and a²/b² would be 101. Then b² would be a divisor of 101 and 101 wouldn't be prime. That contradicts.
I will think b but I could be wrong
