Answer:

(-5, 0)

Step-by-step explanation:

f(x) = (x - 1)(x2 + x - 20) = 0

x - 1 = 0

x = 1

x^2 + x - 20 = (x + 5)(x - 4)

x + 5 = 0; x - 4 = 0

x = -5; x = 4

Answer: (-5, 0)

A. Name the smallest angle and the largest angle of the following triangles: F 6 S 5 1. A J 5.03 7 5 G B H 5.1 2. D 4 3 E

I am Lyosha [343]

Answer:

(smallest, largest) = (B, C), (D, E), (G, J)

Step-by-step explanation:

Side lengths of a triangle are proportional to the sine of the opposite angle. In a triangle, a larger angle will always have a larger sine. That means the smallest angle is opposite the shortest side, and the largest angle is opposite the longest side.

The shortest side is 5 units, opposite angle B. The longest side is 7 units, opposite angle C.

smallest angle: B
largest angle: C

The shortest side is 3 units, opposite angle D. The longest side is 5 units, opposite angle E.

smallest angle: D
largest angle: E

The shortest side is 5 units, opposite angle G. The longest side is 5.1 units, opposite angle J.

smallest angle: G
largest angle: J

<em>Additional comment</em>

Angles in a triangle may exceed 90°. The sine function actually is decreasing for angles above 90°. However, since the total of angles of a triangle must be exactly 180°, there <em>cannot be two angles in a triangle such that the smaller angle has the larger sine</em>.

Please help me with question #6!!!

Bumek [7]

Previous balance:

+ $481,47→ 11/30
- $300,00 → 11/02
- $68,99 → 11 / 10
- $45,00 → 11/15
- $72,75 → 11/17
----------------------------
+ $481,47 - $113,26 =
+ $368,21

new balance:

+ $481,47→ 11/30
- $300,00 → 11/02
- $ $\diagup\!\!\!\! 68,\diagup\!\!\!\!99$ → 11 / 10 for -$58,99
- $45,00 → 11/15
- $ $\diagup\!\!\!\! 72,\diagup\!\!\!\!75$ → 11/17 for $ 0
-------------------------------------------------------------------------------------
+ $481,47 - $196,01 =
+$285,46

Answer:
$\boxed{+285,46}$

COMPRÉ 30 LIBROS A 40 BS CADA UNO ; VENDÍ UNOS CUANTOS A 360 BS, A 36 BS CADA UNO. ¿ EN CUANTO DEBO VENDER CADA UNO DE LOS RESTA

Ksenya-84 [330]

Answer:

28BS

Step-by-step explanation:

Compré 30 libros a 40 bs cada uno;

Precio de costo = 30 × 40BS

= 1200 BS

Vendí unos pocos a 360 Bs, a 36 Bs cada uno.

Número de libros vendidos = 360 BS / 36 BS

= 10 libros

Número de libros restantes = 40 BS - 10 BS

= 30 BS

¿Cuánto debo vender cada uno de los libros restantes para no perder ni ganar nada?

Para no ganar ni perder nada, la cantidad total que queda para vender los libros =

1200BS - 360 BS = 840 BS

La cantidad para vender cada uno de los libros restantes sin ganar ni perder nada se calcula como:

840BS / Número de libros restantes

= 840BS / 30BS

= 28BS
