Due to the rising new crown infections in the United States, the European Union 30 suggestion list its members will be removed from the security in the United States, this means that passengers from the United States could face a more strict quarantine restrictions, such as new crown detection and isolation measures, etc. Some eu countries, such as Germany and Belgium, have been listed as red alert to the United States, the United States entry passengers need to carry on the detection and isolation, but France and the Netherlands will remain as safety state in the United States.

According to Our World, according to Data from the Data in the week ended Aug. 28, the average daily number of cases has risen to more than 450 cases per one million people, and the European Union in mid-june list will join the security in the United States, the Data is less than 40 cases.

At present, the eu allows most non-eu visitor arrivals have been fully vaccinated, but according to the regulation of various countries, visitors need to detection and isolation.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

(3x-8) or (3x+8)

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
