Answer:
0 or 2
Step-by-step explanation:
The Fundamental theorem of Algebra states that a polynomial of degree n has n roots.
Since degree 3 then there are 3 possible roots
Since complex roots occur in conjugate pairs then
There can be 0 or 2 complex roots.
Y=5x-4 is linear
y=x/3 is linear
y=x^3+1/3 is non linear
Basically linear means it is a straight line when graphed. So anything with exponts is non linear by default among some other rules for determining linear or nonlinear Hope this helps! Please rate my answer and help me also! Thank YOU!!!!!:)
5^-3=0.008
1/2=0.5
0.5*0.008=0.004
5/0.004=1250
Answer of 9 = 7 because those red arcs mean that both of those angles are the same, so if the angle on the right is 7, the angle on the left is 7
Answer of 11 = 60, because this is a equilateral triangle, which means all the sides are the same.
180 - 60 = 120 (180 is in the equation because all interior sides of a triangle add up to 180)
120 divided by 2 = 60
Draw or sketch out any problems like this, otherwise they appear abstract.
A circle’s area can be calculated by (pi d^2)/4 We have an area of 56 cm (^2?), so
pi d^2 = 56 x 4 (or 224) d^2 = 224/pi, d = √(224/pi)
A circle circumscribed around a square has a diameter equivalent to the length of the square’s diagonal, so the square’s diagonal is √(224/pi) (same as the circle diameter…)
A square’s side can be calculated, knowing its diagonal length, by use of Pythagoras’ theorem… The diagonal √(224/pi) is squared, divided by two, since the square’s sides are all equal, and the resulting number’s square root is calculated.
Squaring √(224/pi), we get 224/pi, and dividing by two, we get 112/pi, which is 35.6507 (cm^2), and the square root is 5.9708 cm, the side of the square.
I cannot emphasize enough that a drawing or sketch is an invaluable tool for these tasks, it saves having to retain a “picture” in your head. Note that a calculator was not required up until the last moment, dividing 112 by pi, and finding the square root of that answer. Picking up the calculator too early obliges you to transcribe numbers from the calculator to paper, and that can lead to issues. Try to enjoy maths, see it as a challenge not a chore. (and use correct units!)
