The answerthe complement of the question is perhaps the functionf(x)= x4 - 5x2to find the value of x-intercepts, just egalize f(x)= x4 - 5x2 to 0, and solve the equation.that is x4 - 5x2 = 0 equivalent to x²(x²-5) = 0, this implies x²-5 = 0 and x²=0,it implies x=0 and x²= 5, which means x = +/- sqrt(5)so the x intercepts are x=0, x = - sqrt(5) and x = +sqrt(5)
finally the answer is 3 x intercepts
Answer:
25 snowcones
Step-by-step explanation:
0.75s = 18.75, where (s) is the number of students/snowcones ordered
Divide both sides by 0.75:
0.75s/0.75 = 18.75/0.75
s = 25
Lna^b = blna
let y = lne^e
so y = lne^e = e lne
lne = 1
y = e which is a constant (Euler's number) ~= 2.718
For Euler's number estimating methods request in a comment.
In this case if x<100 George will be losing money. So he will only earn a profit when he sells more than 100 DVDs. Essentially (x-100) represents his break-even point.
