Answer:
The answer my friend is B. :)
Step-by-step explanation:
H(x) = 4x⁴ - 5x³ + 2x² - x + 5
Take the coefficients, we have:
4 -5 2 -1 5
From the first coefficient to the second coefficient, there's a change of sign from positive to negative (positive four to negative five)
From the second coefficient to the third coefficient, there's a change of sign from negative to positive (negative five to positive two)
From the third coefficient to the fourth coefficient, there's a change of sign from positive to negative (positive two to negative one)
From the fourth coefficient to the fifth coefficient, there's a change of sign from negative to positive (negative one to positive five)
The changing of sign happened four times, and it means h(x) has four positive real zeros or less (even numbers of zeros), so h(x) could have either four or two real zeros.
The maximum number of solutions for a polynomial of degree four is four solution, so there are no negative zeros.
Answer:
18.1cm
Step-by-step explanation:
First we will split trapezium on two geometric figure.
One is rectangle and the second is right triangle.
When we subtract 11-4=7cm we get one cathetus of the right triangle a=7cm also we know hypotenuse which is c=16cm.
We will use Pythagorean theorem to find the second cathetus b
b=√16∧2-7∧2= √256-49= √207 ≈ 14.39cm =DC =>
AC =√(DC)∧2+(AD)∧2= √14.39∧2+11∧2= √207+121= √328= 18.1cm
AC=18.1cm
1/3 = grape juice in the bottle
2/3 = fruit mix so that means that a third of this is grape because this is mixed equally with 3 diff juices.
2/3x1/3= 2/9 is grape in the mixed juice
So you gotta add the amount of grape in the mixed juice to the amount of grape juice in the bottle before drink was added
1/3 + 2/9 = 5/9 is grape juice
No no one else has to follow up
Ok ok ty just got
Ok Ahhxjx is going to the call for me daddy lol yeah bye bye daddy daddy yeah yeah ok ok
No it’s not going on
