The first thing we must do for this case is to define a variable.
We have then:
n: unknown number.
We write the algebraic expression:
13 - 4n
For n = 3 we have:
13 - 4 (3) = 13 - 12 = 1
Answer:
An expression that represents this phrase is:
13 - 4n
its value if n = 3 is:
1

Answer: V=9651 ft^3
Explanation: This is a volume question and the formula for volume of a cylinder is πr^2h.
The radius is the diameter divided by 2, which is 8.
We can put the equation in terms of π by doing π*(8^2*48)=3072π.
Solving this gives us about 9650.972632, which you can round to get 9651.
Answer:
10
Step-by-step explanation:
10x²-14x+k = 0
x1 = sin a
x2= cos a
x1+x2 ≤ 2
x1. x2 ≤ 1 => k/10 ≤ 1
k ≤ 10
so the value of k should be 10
