Jerome found the lengths of each side of triangle QRS as shown, but did not simplify his answers. Simplify the lengths of each s

Margaret [11]

Answer:

$QR = 6.0033$

$QS = 8.22$

$RS = 6.0033$

QRS is isosceles

Step-by-step explanation:

Given

See attachment for complete question

From the attachment, we have the following parameters $QR = \sqrt{(-3-0)^2+(-5.2-0)^2}$

$QR = \sqrt{9+27.04}$

$QS = \sqrt{(-3-5)^2+(-5.2-(-3.322))^2}$

$QS = \sqrt{64+3.53} = \sqrt{67.53$

$RS = \sqrt{(0-5)^2 + (0 - (-3.322))^2}$

$RS = \sqrt{(25 + 11.04}$

Solving further, we have:

$QR = \sqrt{9+27.04}$

$QR = \sqrt{36.04}$

$QR = 6.0033$

$QS = \sqrt{64+3.53} = \sqrt{67.53}$

$QS = 8.22$

$RS = \sqrt{25 + 11.04}$

$RS = \sqrt{36.04}$

$RS = 6.0033$

From the calculations;

$RS = QR = 6.0033$

<em>This means that: QRS is isosceles</em>

Answer:

-5 + 12 i

Step-by-step explanation:

(2 + 3i)^2 = 4 + 6i + 6i + 9i^2

= 4 + 12 i + 9(-1)

= - 5 + 12 i

Compute the rate of discount allowed on a lawnmower that lists for $168 and is sold for $105. The rate of discount allowed is 43

kvasek [131]

Answer:

The rate of discount of a lawnmower is 37,5%

Step-by-step explanation:

Sale price formula is

S = p - rp

where S = sale price,

r = discount percentage rate

p = the original price.

Isolating r

r= (p-S)/p

r= ($168- $105)/$168

r=0.375

r= 37,5%
