Answer:
d. Two complex solutions
Step-by-step explanation:
We have been given a trinomial 
and we are supposed to predict the type of solutions of our given trinomial.
We will use discriminant formula to solve for our given problem.
, where,
,
,
Conclusion from the result of Discriminant are:
Upon substituting our given values in above formula we will get,
Since our discriminant is less than zero, therefore, out given trinomial will have two complex solutions and option d is the correct choice.
Answer:
The whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square is 6 ft
Step-by-step explanation:
Here we are required find the size of the sides of a dunk tank (cube with open top) such that the surface area is ≤ 160 ft²
For maximum volume, the side length, s of the cube must all be equal ;
Therefore area of one side = s²
Number of sides in a cube with top open = 5 sides
Area of surface = 5 × s² = 180
Therefore s² = 180/5 = 36
s² = 36
s = √36 = 6 ft
Therefore, the whole number dimension that would allow the student to maximize the volume while keeping the surface area at most 160 square = 6 ft.
It should be 30.4
Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2)
You should end up with -56 + 25.6
Next you add those two numbers and you end up with 30.4.
I hope this helps!
yes
Step-by-step explanation:
parallelogram are quadrilaterals with two sets of parallel sides. since square must be quadrilaterals with two sets of parallel sides ,then all squares are parallelogram ,a trapezoid is quadrilateral.
