Answer:

1. 20.505N

2.8.876N

3. -13.686N

Step-by-step explanation:

1. xcos75 + xsin75 = 26N

x(cos75+sin75) = 26; x = 26/(cos75+sin75)

x = 26/1.2247 = 21.229

vertical component is 21.229 sin75 = 20.505 N

2. xcos30 + xsin30 = 14N

x(cos30 + sin30) = 14; x = 14/1.366 = 10.249

horizontal component is 10.249 x cos30 = 8.876N

3. net force on the vertical direction.

xcos37 + xsin37 = 24

x(cos37+sin37) = 24; x = 24/(cos37+sin37) = 24/1.400 = 17.137

verical component is 17.137 x sin37 =10.314

we are given that the box excert a force of 22N downwards, so the net vertical component is 10.314 - 24 = -13.686N

Función inversa f(x) = 7/x -9

Tanya [424]

Answer:

F-1(x)=7/(x+9)

Step-by-step explanation:

Change F(x) to y so y=7/x -9

Swap variables x=7/y -9

Solve x+9=7/y

7/(x+9)=y

Then change y to F inverse

F-1(x)=7/(x+9)

Thats ur inverse!!!

At the end of her work day, Rosa leaves her office and goes directly to her bank. On the graph that shows the locations of Rosa'

ikadub [295]

Find the distance between the point of bank and the point of office.

$\sqrt{(x2 - x1)^{2}+ (y2 - y1)^{2}}$
$\sqrt{(-4 - (-6)^2 + (4 - (-3)^2}$
$\sqrt{(2)^2 + (7)^2}$
$\sqrt{4 + 49}$
$\sqrt{53}$

The distance she travels is approximately 7.3 km.

Hope this helps :)
