Wires are attached to a pole to make it more secure. The diagram shows one of those wires having a length of 220 feet. The angle
LuckyWell [14K]
The wire, the pole and the segment joining the leg of the pole to the wire in the ground form a right triangle whose hypotenuse is the wire, and the side opposite to the angle 36° is the pole.

By right triangle trigonometry, sin36°=(opposite side)/(hypotenuse.)

Substituting, we have 0.588=(opposite side)/220, thus the length of the opposite side, which represents the length of the pole, is

Cual de estos utiliza la propiedad distributiva para mostrar la forma expandida de la expresion: -4 . (-5 + 3)
mr Goodwill [35]

Respuesta:

8

Explicación paso a paso:

Si A, B y C son números enteros, según la propiedad distributiva;

A (B + C) = AB + AC

tenga en cuenta que A se distribuyó sobre B y C

Aplicando esto para expandir la expresión dada -4. (-5 + 3)

-4. (-5 + 3)

= -4 (-5) + -4 (3)

= 20 + (-12)

= 20 - 12

= 8

Por lo tanto, la respuesta requerida es 8

Sherman has two sequences . The first sequence is described by the explicit rule f(n) = 15n + 4 and the second sequence is descr
Viktor [21]

Answer:

Step-by-step explanation:

Given the explicit function as

f(n) = 15n+4

The first term of the sequence is at when n= 1

f(1) = 15(1)+4

f(1) = 19

a = 19

Common difference d = f(2)-f(1)

f(2) = 15(2)+4

f(2) = 34

d = 34-19

d = 15

Sum of nth term of an AP = n/2{2a+(n-1)d}

S20 = 20/2{2(19)+(20-1)15)

S20 = 10(38+19(15))

S20 = 10(38+285)

S20 = 10(323)

S20 = 3230.

Sum of the 20th term is 3230

For the explicit function

f(n) = 4n+15

f(1) = 4(1)+15

f(1) = 19

a = 19

Common difference d = f(2)-f(1)

f(2) = 4(2)+15

f(2) = 23

d = 23-19

d = 4

Sum of nth term of an AP = n/2{2a+(n-1)d}

S20 = 20/2{2(19)+(20-1)4)

S20 = 10(38+19(4))

S20 = 10(38+76)

S20 = 10(114)

S20 = 1140

Sum of the 20th terms is 1140
