Answer:
Step-by-step explanation:
One way to write a ratio is as a fraction:
Example:
Another way is by writing it using the word "to," as "9 to 6."
The most common way or the one you will see the most is the using a colon between the two numbers, 9 : 6.
Now let me be clear that all three of these ways are actually saying the <u>EXACT SAME THING</u>!!!
(a + bi)(2 + 3i) - i = (-11 + 5i)(1 - i)
(a + bi)(2 + 3i) - i = -11 + 11i + 5i - 5i²
(a + bi)(2 + 3i) - i = -6 + 16i
(a + bi)(2 + 3i) = -6 + 17i

a + bi = 3 + 4i
a = 3, b = 4

Zeroes in Division:
1. When you divide zero by any nonzero number, the quotient is zero.
For example;
0/10 = zero
2. When you divide a nonzero number by zero, the quotient is undefined or not possible.
5/0 = undefined or math error.
Ones in Division:
1. When you divide any non-zero number by one, the quotient is the dividend itself.
For example;
9/1 = 9
2. When you divide any non-zero number by itself, the quotient is the number itself.
For example;
9/9 = 1
Zeroes in Multiplication:
1. When you multiply zero by any non-zero number, the product is zero. For example;
0 x 10 = zero
2. When you multiply a non-zero number by zero, the product is still zero.
For example;
12 x 0 = zero
Ones in Multiplication:
1. When you multiply one by any non-zero number, the product is the non-zero number itself.
For example;
1 x 10 = 10. 2.
When you multiply a non-zero number by one, the product is still the number itself.
For example;
12 x 1 = 12</span>
Answer:
52 metros.
Step-by-step explanation:
En este caso debemos usar las identidades trigonométricas. La información por medio del enunciado es:
*Sombra proyectada, que mide 20 metros y sería el cateto adyacente
*Ángulo de inclinación que son 69°
Con estos datos podemos calcular el cateto opuesto que sería altura, por medio de la identidad de la tangente:
tan α = CO/CA
CO = tanα * CA
CO = tan(69) · 20 m
CO = 52 metros
Lo que quiere decir que la altura del edificio es de 52 metros.
