Answer:
x = 1.723
Step-by-step explanation:
The zeros of a function f(x) are the points where the function crosses the x-axis. At these points, the function will have a value of zero, that is;
f(x) = 0
We simply graph the function and determine the points where it crosses the x-axis. From the attachment, f(x) crosses the x-axis at;
x = 1.723
Answer:
Step-by-step explanation:
We have given the function:
f(x)=-3x³+6x+5.
We have to find the zeros of the function.
The zeros of the function are the points where the function cuts the x-axis.
And at that points function has value zero.
So to find these points put f(x)= 0 we get,
-3x³+6x+5=0
As from the graph the function cuts the x-axis at x = 1.723 so, this is the zero of the function.

Step-by-step explanation:
Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:
With this Pythagorean Triple, we know that our dimensions are correct. Now, to find the perimeter, just add up all the sides EXCEPT for the divider:
