Answer:
a, b, d and f
Step-by-step explanation:
To find which equation will have a a mass less than 50 mg after 2 hours, we just need to use the value of x = 2 and then verify if the values of y are less than 50:
a. y = 100*(0.5)^2 = 25 -> apply
b. y = 500*(0.3)^2 = 45 -> apply
c. y = 80*(2)^2 = 320 -> doesn't apply
d. y = 10*(1.2)^2 = 14.4 -> apply
e. y = 30*(1.5)^2 = 67.5 -> doesn't apply
f. y = 80*(0.2)^2 = 3.2 -> apply
g. y = 100*(2)^2 = 400 -> doesn't apply
<span>y - k = a(x - h)²
</span><span>y = (x − 5)² + 8 -------> y-8 = (x-5)²
</span>y - k = a(x - h)²
y - 8 = (x - 5)²
Compare these formulas we can see that k=8, h =5.
