Step-by-step explanation:
Multiply numerator and denominator by the conjugate of the denominator.
[tex]\dfrac{4-3i}{4+3i}=\dfrac{(4-3i)(4-3i)}{(4+3i)(4-3i)}=\dfrac{7-24i}{25}=\boxed{0.28-0.96i}[/tex]

Theo has 3 sweets and 2 white sweets he picks a sweets at random write down the probability that theo picks a red sweet
Answer:
the probability is 3 ÷ 5
Step-by-step explanation:
The computation of the probability is given below:
= number of red sweets ÷ total number of sweets
= 3 sweets ÷ (3 red sweets + 2 white sweets
= 3 sweets ÷ 5 sweets
= 3 ÷ 5
Hence, the probability is 3 ÷ 5

Cuál es la expresión algebraica que determina la sucesión anterior 10,17 ,24
Answer:
no se si lo necesitas en español
Step-by-step explanation:
Al darse cuenta de que
10
=
7
(
1
)
+
3
,
17
=
7
(
2
)
+
3
etc.
Una secuencia aritmética es aquella en la que alguna diferencia constante entre los números en una secuencia le da un patrón para llegar al siguiente número no listado en la secuencia.
En este caso, la diferencia es
7
. Cuando uno trabaja al revés y resta
7
desde
10
, el resultado es
3
. En el
0
a término, asumimos que
norte
>
0
para series y secuencias.
Asi que,
3
es el
0
th término, dándonos la intersección con el eje y, por así decirlo. Ahora simplemente tendríamos que reconocer que si incrementamos
norte
integralmente, y tenemos una diferencia de
7
de término a término, esa es la operación
7
norte
.
Entonces, la secuencia aritmética se generaría como:
a

(

=

+
7
(
1
)
+
7
(
1
)

7
(
1
)
=
24
etcétera. Cada término tiene
a
0
dentro de él, agregado a
7
veces el índice actual indicado por
a
norte
. Entonces, solo tenemos la definición recursiva:
a
norte
=
a
norte
-

7
o la definición general:
a

=

cómo puedo allar el valor absoluto de -4
Answer:
4
Step-by-step explanation:
abs(-4)=4
Answer:
Si recuerda, el valor absoluto de un número es el número "hecho positivo" al eliminar el signo menos si el número es negativo y simplemente dejar pasar el número si es positivo. Entonces, por ejemplo, el valor absoluto de -3 es 3 y el valor absoluto de 3 es 3.

Step-by-step explanation:
The face of a clock is divided into 12 equal parts. The radius of the clock face is 6 inches. Assume the hands of the clock will form a central angle.
The face of a clock is divided into 12 equal parts.
Which statements about the clock are accurate? Check all that apply.
The central angle measure when one hand points at 2 and the other points at 4 is 60°.
The circumference of the clock is about 19 in.
With one hand at 5 and the other at 10, the minor arc formed by the hands is about 15.7 in.
The minor arc measure when one hand points at 1 and the other hand points at 9 is 150°.
The length of the minor arc between 11 and 2 is the same as the length of the minor arc between 7 and 10.
Answer:
a , c , e
Step-by-step explanation:
just took it ;)
The statements about the clock are accurate are;
The central angle measure when one hand points at 2 and the other points at 4 is 60°.With one hand at 5 and the other at 10, the minor arc formed by the hands is about 15.7 in.The length of the minor arc between 11 and 2 is the same as the length of the minor arc between 7 and 10.Why are the statement above correct?1. Note that the face of a clock is divided into 12 equal parts and the Angle of each part is= 30°
If one hand points at 2 and the other points at 4, then it is divided into two parts that is 2 to 3 and 3 to 4.
The angle that will be formed then will be = 2 (30) = 60°
So therefore option one is correct
111. When a person place one hand at 5 and the other hand at 10, then it is divided into 5 parts.
The angle that is formed= 30(5) = 150°.
Therefore, the arc length =(37.68) = 15.7.
So therefore, Option three is correct.
V. When the length of the minor arc ranges from 11 to 2, then this is divided is 3 parts.
So therefore, 3(30) = 90°
The minor arc is said to ranges from 7 to 10 and it is represented by 3(30) = 90°
So therefore option five is correct.

Lamar has a bag of beads. He gives 20 beads to his sister. Then he makes 4 identical necklaces with the remaining beads. Write an expression that represents the number of beads on each necklace.
Answer:
x/4 - 5
Step-by-step explanation:
Let :
Number of beads in bag = x
Number of beads left = x - 20
Identical beads made from remaining = 4
Number of beads on each necklace :
Number of beads left / number of beads made
= (x - 20) / 4
= x/4 - 5

Subtract (-3f - 4g + 9) - (2 - 6f + 5g).
Answer:
Step-by-step explanation:
Remove the brackets. Watch out for that minus sign. It affects all three terms in the right bracket.
(-3f - 4g + 9) - (2 - 6f + 5g)
-3f - 4g + 9 - 2 + 6f - 5g
+3f - 9g + 7 is your answer.
Answer:
3f−9g+7
Step-by-step explanation:
(−3f−4g+9)−(2−6f+5g)
To find the opposite of 2−6f+5g, find the opposite of each term.
−3f−4g+9−2−(−6f)−5g
The opposite of −6f is 6f.
−3f−4g+9−2+6f−5g
Subtract 2 from 9 to get 7.
−3f−4g+7+6f−5g
Combine −3f and 6f to get 3f.
3f−4g+7−5g
Combine −4g and −5g to get −9g.
3f−9g+7
