Answer:
x intercept 2
y intercept 1
Step-by-step explanation:
The x intercept is where it crosses the x axis( or horizontal axis) It crosses at x =2
The y intercept is where it crosses the y axis ( or vertical axis). It crosses at y =1
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 = 
× ln(
)
where, t = time from start of reaction
k = reaction constant
A(0) = initial concentration; A = present concentration.
⇒ 4.5 billion = 4500 million years = × ln2.
Now, given 95.82% of parent U-238 isotope is left.
⇒ t = × ln()
t = 
× ln(
)
⇒ t ≅ 277 million years.
Use the stay, change, flip method.
keep the first fraction the same, change the division to multiplication and flip the last fraction. you may then have the opportunity to cross simplify.
Answer: 27.60
Step-by-step explanation:
24 x .15 = 3.60
24 + 3.60 = 27.60
