Bacteria left in 1st hour=100*0.9¹=90
2st hour=100*0.9*0.9=100*0.9²
....
after 5 hours=100*0.9^5
Step-by-step explanation:
k = √(49 - 12√5)
= √(45 + 4 - 2 √180)
= √45 - √4
= 3 √5 - 2.
<em>So, k + 2 = 3 √5 - 2 + 2 = 3 √5.</em>
Answer:
-7/3.
Step-by-step explanation:
Convert to the form y < mx + c where m is the slope:
7x + 3y < -26 Subtract 7x from both sides:
3y < -7x - 26 Divide through by 3:
y < (-7/3)x - 26/3
So the slope is -7/3.
F(x) would appear in linear and quadratic functions.
The answer is A, B, and C
