This is easy what you should do is plug in 4 for the x's in the rational expression and what it should look like when finished is: 12+4/4+4.
To remember the steps in which and equation should be solved is:
P=Parentheses
E=Exponents
M=Multiply
D=Division
A=Add
S=Subtract
So the answer to the equation is: 17
Hoped this helped you into solving more equations like this one. :)
Answer:
V = 4/3 pi or approximately 4.187 ft^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
The radius is 1 ft
V = 4/3 pi (1)^3
V = 4/3 pi
We can approximate pi by 3.14
V = 4/3 (3.14)
V = 4.186666666 ft^3
Using exponential function concepts, it is found that it represents a decay of 0.9%.
<h3>What is an exponential function?</h3>
A decaying exponential function is <em>modeled </em>by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function is:

Hence:


Thus, it represents a decay of 0.9%.

Answer:
true!
Step-by-step explanation:
this is more of a statement then a question.
Answer:
<u><em>The length of AD is 32 feet</em></u>
Step-by-step explanation:
<u>Proportional distances
</u>
When distances are proportions of others, we can express all of them as relative fractions until we reach some known distance and solve for the desired length
Let's call x the length of AD. Given C is the midpoint of AD, then

Given B is the midpoint of AC, then

If we know BC=8 feet


The length of AD is 32 feet
