Answer:

3047.52

Step-by-step explanation:

If you do the amount of pieces that they need is 112, and it costs 27.21 per piece, then what you have to do is 112*27.21

112 * 27.21 is 3047.52

Choose the expression that represents a quadratic expression. 9x − 2 5x2 + 9x − 1 −2x3 + 8x2 − 7x + 1 x4 − 12x3 + 8x2 − 7x + 1
elena-s [515]

Answer:

5 {x}^{2}  + 9x - 1

Step-by-step explanation:

A quadratic expresion is of the form

a {x}^{2}  + bx + c

where

a \ne0

The give options are:

9x-2

5{x}^{2}+9x - 1

-2x^3+8 {x}^{2}  -7x +1

x^4-12x^3+8 {x}^{2}  -7x +1

From the given options, the only expression which is quadratic is

5 {x}^{2}  + 9x - 1

where a =5, b=9 and c=-1

Therefore the correct choice is the second option.

Use algebraic methods to find as many intersection points of the following curves as possible. Use graphical methods to identify
Anon25 [30]

Answer:

Step-by-step explanation:

r =5sin i

r=5 cos i

divide

tan i=1=tan (π/4),tan(π+π/4)

or tan i=tan (π/4),tan(5π/4)

or  tan i=tan (2n π+π/4),tan (2nπ+5π/4)

or tan i=tan ((8n+1)π/4),tan((8n+5)π/4)

i=(8n+1)π/4,(8n+5)π/4

where n is an integer.

so we get infinite points of intersection.
