7 0

Answer:

f = 5.12

Step-by-step explanation:

f(8)=0.8(8)^2

f(8)=6.4^2

f(8)=40.96

f(8)/8 = 40.96/8

f = 5.12

i'd really appreciate being marked brainliest if you want! i appreciate it :)

To get from your house to class you walk east 579 feet. after class you walk south west 965 feet to meet your friends at lunch.
svlad2 [7]
You formed a right-angled triangle. I drew this out at first, but you can double check it as 579² + 772² = 965², which is the rule for a right-angled triangle. I hope this helps!

A rock outcrop was found to have 95.82% of its parent U- 238 isotope remaining. Approximate the age of the outcrop. The half-lif
mixer [17]

Answer:

A) 277 million years

Step-by-step explanation:

Here, decay of U-238 is first order reaction. (since most of the nuclear decays are first order).

so, the equation t = \frac{1}{k} × ln(\frac{A(0)}{A})

where, t = time from start of reaction

           k = reaction constant

           A(0) = initial concentration; A = present concentration.

     ⇒ 4.5 billion = 4500 million years = \frac{1}{k}× ln2.

Now, given 95.82% of parent U-238 isotope is left.

⇒ t = \frac{1}{k} × ln(\frac{A(0)}{A})

  t = \frac{4500}{ln2} × ln(\frac{100}{95.82})

⇒ t ≅ 277 million years.
