Answer:
2998 ; 17%
Step-by-step explanation:
Given the function:
t(c)=-3970.9(ln c)
c = % of carbon remaining ; t = time
1.) c = 47% = 47/100 = 0.47
t(0.47) = - 3970.9(In 0.47)
t = - 3970.9 * −0.755022
t = 2998.119
t = 2998
B.)
t = 7000
t(c)=-3970.9(ln c)
7000 = - 3970.9(In c)
7000 / - 3970.9 = In c
−1.762824 = In c
c = exp(−1.762824)
c = 0.1715596
c = 0.1715596 * 100%
c = 17.156% ; c = 17%
A(1) = -6 +(1 -1)*(1/5) = -6
A(4) = -6 +(4 -1)*(1/5) = -5 2/5
A(10) = -6 +(10 -1)*(1/5) = -4 1/5
Answer:
558/1
Step-by-step explanation:
The value of Θ is 40.32°
Step-by-step explanation:
We can see that the given triangle is a right triangle.
According to Θ, the perpendicular is the side opposite to theeta
So,
P = 11
and
H = 17
Now using the trignometric ratio for theeta containing perpendicular and hypotenuse
Let
Θ = x
The value of Θ is 40.32°

Answer:
27
Step-by-step explanation:
Replace the x in f(x) by g(x) to get (f o g)(x)
= 2(4x - 3) - 7
= 8x - 6 - 7
= 8x - 13
so (f o g) (5)
= 8(5) - 13
= 27
