Answer:
Step-by-step explanation:
The ratio of a circumference to its diameter is equal to an irrational number, called pi, roughly equal to 3.14, denoted by symbol
Therefore, knowing the diameter d, the circumference is equal to d*π
The value of the function f(x)=6/-2+2 at x=4 after rounded to the nearest tenth is -2.4.
Given Function of x : f(x)=6/-2+2
The given function showing the relationship between x and f(x) is f(x)=6/-2+2 where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.
f(4)=6/-2+2 ( The value of e is 2.7812)
f(4)=-3+2
f(4)=-3+2*0.30119 (The value of is 0.30119)
f(4)=-3+0.60238
f(4)=-2.3972
Round -2.3972 to tenth is -2.4.
Hence the value of function of at x=4 is -2.4.

Answer: $26
Step-by-step explanation:
Let the number of $2 price increases be x.
This means that if the price is 10+2x, 42-2x shoes are sold.
So, the revenue is (10+2x)(42-2x).
To maximize profit, we must maximize revenue.
The maximum is at , so the price should be 10+2(8)=$26.
Complex roots occur as conjugates so the other root is 3 + 2i
so we have the factored form
(x - (3 - 2i)(x - (3 + 2i)
= (x - 3 + 2i)(x - 3 - 2i)
= x^2 -3x - 2ix - 3x + 9 + 6i + 2ix - 6i- 4i^2
= x^2 -6x + 9 + 4
= x^2 - 6x + 13 Answer
