Hello there!
f(x)=x
f(x) is also known as y
x is 3, which means the x value on the right is 3
Answer: f(3)=3
Answer:
The length is 
The width is 
Step-by-step explanation:
we know that
The area of rectangle is equal to
we have
so
-----> equation A
------> equation B
substitute equation B in equation A and solve for L
using a graphing tool------> solve the quadratic equation
The solution is 
see the attached figure
<em>Find the value of W</em>
2n=16 divide both sides by 2 you get n=8
Answer:
A counter clockwise
Step-by-step explanation:
Answer:
Initial amount is 523 grams
Amount after 100 years is 52 grams
Step-by-step explanation:
General exponential function for radioactive substances is given by
A(t) = Ao(1/2)^t/t1/2
Where,
A(t) is the amount remaining after t years
Ao is the initial amount of the radioactive substance
t is the number of years required for the radioactive substance to decay to A
t1/2 is the half-life of the radioactive substance
Comparing A(t) = 523(1/2)^t/30 with the general exponential function
Initial amount (Ao) = 523 grams
A(t) = 523(1/2)^t/30
t = 100
A(100) = 523(1/2)^100/30 = 523×0.5^3.333 = 523×0.0992 = 51.8816 = 52 grams (to the nearest gram)
