Answer:
The answer to your question is letter B
Step-by-step explanation:
Process
1.- Write the function
f(x) = - 2x² + 2x - 3
Find f(5)
2.- Substitute x for 5
f(5) = -2(5)⁵ + 2(5) - 3
3.- Simplify
f(5) = -2(25) + 10 - 3
f(5) = -50 + 7
f(5) = -43
Half life = 1250 years
Start amount = 36
End amount = 15
Time = ?
15 = 36 * (1/2)^(x/1250)
0.417 = (1/2)^(x/1250)
ln(0.417) = x/1250 * ln(1/2)
x = 1577.95 years
Answer:
x = -10
Step-by-step explanation:
5 (x + 8) = -10
5x + 40 = -10
5x = -50
x= -10
12-4=e.8 not 10. I think you need to look at the question and look at what you wrote.
I think the answer would be either 12 or 14 cm. If not right, I am very sorry. I hope I've helped.
