Answer:

3.3

Step-by-step explanation:

=  >  \frac{4 \frac{2}{5} }{1 \frac{1}{3} }  \\  \\  =  >  \frac{ \frac{20 + 2}{5} }{ \frac{3 + 1}{3} }  \\  \\  =  >  \frac{ \frac{22}{5} }{ \frac{4}{3} }  \\  \\  =  >  \frac{22}{5}  \times  \frac{3}{4}  \\  \\  =  >  \frac{11}{5}  \times  \frac{3}{2}  \\  \\  =  >  \frac{33}{10}  \\  \\  =  > 3.3

Determine algebraically whether the function is even, odd, or neither even nor odd.
ololo11 [35]

Answer:

odd

Step-by-step explanation:

Just so you know there are shortcuts for determining if a polynomial function is even or odd. You just to make sure you use that x=x^1 and if you have a constant, write it as constant*x^0 (since x^0=1)

THEN!

If all of your exponents are odd then the function is odd

If all of your exponents are even then the function is even

Now you have -4x^3+4x^1

3 and 1 are odd it is an odd function

This a short cut not the legit algebra way

let me show you that now:

For it to be even you have f(-x)=f(x)

For it be odd you have f(-x)=-f(x)

If you don't have either of those cases you say it is neither

So let's check

plug in -x  -4(-x)^3+4(-x)=-4*-x^3+-4x=-4x^3+-4x

that's not the same so not even

with if we factor out -1 .... well if we do that we get -(4x^3+4x)=-f(x)

so it is odd.

You are asked to help out in the merchandise department. You sell $750 worth of $30 math teaching kits. How many kits did you se
Alex Ar [27]
$750 / $30 = 25 maths teaching kids

$350 / $25 = 14 maths starter kits
if you wanted to see if it was right, you would just do 14*25 and you would get $350

hope I helped!!

Use the discriminant, b2 - 4ac, to determine which equation has complex solutions.
ruslelena [56]

Using the discriminant, the quadratic equation that has complex solutions is given by:

x² + 2x + 5 = 0.

<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>

A quadratic equation is modeled by:

y = ax² + bx + c

The discriminant is:

\Delta = b^2 - 4ac

The solutions are as follows:

  • If \mathbf{\Delta > 0}, it has 2 real solutions.
  • If \mathbf{\Delta = 0}, it has 1 real solutions.
  • If \mathbf{\Delta < 0}, it has 2 complex solutions.

In this problem, we want a negative discriminant, hence the equation is:

x² + 2x + 5 = 0.

As the coefficients are a = 1, b = 2, c = 5, hence:

\Delta = 2^2 - 4(1)(5) = 4 - 20 = -16
