Step-by-step explanation:

(2x/5)² . (1x⁴/4)^-1

=(2²x²/5²) . (4/x⁴)

=4x²/25 × 4/x⁴

= 16/25x²

Find two values of b that will make 9 x 2 + b x + 9 a perfect square trinomial.
pav-90 [236]
You want 9x^2 + bx + 9a to be a perfect square trinomial.  Note that 9 x 2 is incorrect and should be written as 9x^2, where "^" represents "exponentiation."

What about a?  Are we supposed to find a also?

One way in which to do this problem is to factor 9 out of the trinomial:

9 (x^2 + (b/9)x + a )

Concentrate now on making x^2 + (b/9)x + a into a perfect square trinomial.

x^2 + (b/9)x                            + a

Take half of the coefficient (b/9) and square the result:  [(b/9)/2]^2 = b^2/81.  

Then, x^2 + (b/9)x + b^2/81 - b^2/81 + a.

          The above quadratic expression can be re-written as

             (x + b/9)^2  - b^2/81 + a.  This is a perfect square trinomial if

                                 -b^2/81 + a = 0.  Solve for b:  b^2/81 = a,
                                                             b/9 = sqrt(a)
                                                              b = 9 sqrt a

40 employees in an office wear eyeglasses. 22 have single-vision correction, and 18 wear bifocals. If two employees are selected
ale4655 [162]

Step-by-step explanation:

The number of way to select 2 employees from 40 is 40C2.

The number of way to select 2 employees from 22 is 22C2.

So the probability of the two employees having single-vision correction is just the number of ways to select the 22 employees (22C2) divided by the total number of ways to select 2 employees (40C2).

22C2 / 40C2 = 77/260

We can use the same technique for the bifocal employees.

18C2 / 40C2 = 51/260

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
Snezhnost [94]

Answer:

Part A:

I have attached the graph of this system of inequalities.

Part B:

Plug in (8,10) into both equations

10 > 3(8) + 10

10 > 24 + 10

10 > 34

This is false!

10 < (-3/4)(8) - 1

10 < (-3)(2) - 1

10 < -6 - 1

10 < -7

This is also false!

So, (8,10) is not included in the solution area for the system.
