shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero

Elanso [62]

Answer:

The given equation will have two roots as +5i and -5i

Step-by-step explanation:

Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function

The given equation is $x^2+25 =0$

This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots

$x^2 = -25 \\x = \sqrt{-25} \\x= \sqrt{-1}* \sqrt{25}\\$

$x = i\sqrt{25}$

x = ± 5i

It will be false to say that -5i will be the only complex root to this equation.

The given equation will have +5i and -5i as its roots.

Lets verify

x = +5i

$(5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25\\-25 + 25 = 0$

x = -5i

$(-5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25 \\-25 + 25 \\ = 0$

Bueno, usaré el español xD

11. Recordemos que entre más negativo es un número, menor es.

a) - 6 > - 10

ya que - 10 es más negativo, por consiguiente es menor, esto llega a confundir ya que tenemos la noción de que si vemos una cifra alta, por consiguiente es mayor, esto pasa en los positivos.

b) 12 > - 16

c) - 7 < 0

d) 35 > - 80

e) -37 < - 24

f) - 40 < 15

g) - 18 < 10

h) - 17 < 0

i) |-21| = |21|

El valor absoluto de un número negativo es su positivo, por lo que también puede ser:

21 = 21.

j) |176| > 0, o también 176 > 0

k) |-479| > |478|, o también 479 > 478

l) |-1375| = |1375|, o también 1375 = 1375

12. De menor a mayor.

a) - 8, - 7, - 4, 0, 3

b) - 16, - 12, - 7, 8, 9

c) - 15, - 13, 0, 9, 11

d) - 47, - 43, - 31, 14, 29

e) - 17, - 15, - 12, 16, 19

f) - 26, - 21, - 10, 17, 26

g) - 61, - 58, - 49, 30, 50

13. De mayor a menor.

a) 6, 4, - 1, - 5, - 7

b) 8, 0, - 7, - 11, - 13

c) 19, 6, - 8, - 10, - 17

d) 21, - 9, - 18, - 24, - 27

e) 53, 47, - 6, - 43, - 48

f) 14, 6, - 18, - 39, - 45

g) 24, 16, 12, - 12, - 17

PLEASE HELP!!! 14 POINTS!

Area=1/2bh

add them
(1/2)ab+(1/2)c^2+(1/2)ab=
ab+(1/2)c^2
ab+(1/2)(a^2+b^2)
not sure which option to pick there are different preferences on what counts as 'simplified'

4. find area
area=LW
area=105*45=4725
depends on the area of the signs
answer is
4725/(areaof1sign)
anyway, round down your answer because you will have an incomplete sign if you don't

5. area=pir^2
1/2 of it is
area=1/2pir^2
area=(1/4)^2pir^2
area=pi((1/4)r)^2
the radius is now 1/4 of what it was originally, meaning that the diameter is also 1/4 of what it is now
we need to know diamater
answer is 1/4 of current diameter

3. unclear

4. area of 1 sign not given, answer is 4725/(areaof1sign), rounded DOWN to nearest integer

5. (404 error, diameter not found) answer is 1/4 of current diameter
