Enter the ordered pair for the vertices for Rx-axis(QRST).
mash [69]

Given:

The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).

To find:

The vertices for R_{x-axis}(QRST).

Solution:

The rule R_{x-axis}(QRST) represents refection of polygon QRST across the x-axis.

If a figure is reflected across the x-axis, then

(x,y)\to (x,-y)

Using this rule, we get

T(-2,3)\to T'(-2,-3)

Q(1,5)\to Q'(1,-5)

R(3,-1)\to R'(3,1)

S(0,0)\to S'(0,0)

Therefore, the vertices for R_{x-axis}(QRST) are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).

Write the complex number z=-10+8i in polar form
jarptica [38.1K]
Hello :
the  polar form is : z = |z |×e^(iθ)
z=-10+8i
 |z | =√((-10)²+(8)²) =<span>√(164)
cos</span>θ = -10/√(164)
sinθ = 8/√(164)
find θ by arctan(8/-10)

Use a system of equations to solve this problem.Bronze is a mix, or alloy, of tin and copper. A metal worker needs 100 g of bron
d1i1m1o1n [39]

Answer:

x = 50 grs

y = 50 grs

Step-by-step explanation:

" x "   is quantity of bronze of 5% tin

" y "   is quantity of bronze of 45% tin

The worker needs 100 grs of bronze and this bronze must be 25% tin

The mathematical expression for the 100 grs condition is:

x + y = 100

And the The mathematical expression for the % condition is:

0,05*x  + 0.45*y  = 0,25 * ( x + y )

The system is:

x + y = 100

0,05*x + 0,45*y = 0,25* ( x + y )

Solving this system we get values of x and y

y = 100 - x

0,05*x  + 0,45* ( 100 - x ) = 0,25 * ( x + 100 - x )

0,05*x  + 45 - 0,45*x = 0,25*( 100 )

0,05*x  + 45 - 0,45*x  = 25

- 0,4*x  = -45 + 25

x = 20/0,4            x = 50  grs

and y = 50 grs
