Answer:
false
Step-by-step explanation:
Answer:
So the slope of this function is 
and the y-intercept is 
Step-by-step explanation:
A first order function has the following format:
In which a is the slope and b is the y-intercept, that is, the value of y when x = 0.
We have the following equation:
We just have to rewrite this equation
Which means that
So the slope of this function is and the y-intercept is
For this problem, we use the formula for
radioactive decay which is expressed as follows:<span>
An = Aoe^-kt
where An is the amount left after time t, Ao is
the initial amount and k is a constant.
We calculate as follows:
An = Aoe^-kt
0.5 = e^-k(9000)
k = 7.7 x 10^-5
An = Aoe^-kt
.10 = e^-</span>7.7 x 10^-5<span>(t)
t = 29903.7 years</span>
Answer:
114.29 ft
Step-by-step explanation:
tan ∅ = Opp/Adj
tan 77 = x/25
x = 25 tan 77
x = 108.29ft
Plus 6ft = 114.29 ft
Step-by-step explanation:
f(-1) = [(-1) + 8]² + 21 = 7² + 21 = 70.
