There are 3 people pulling on an object, the first person pulls with a force of 226 newtons at a direction of 145 degrees the se

Alona [7]

Answer:

$R=883.74N$

Step-by-step explanation:

From the question we are told that:

Force 1 $F_1=226N$

Force 2 $F_2=331N$

Force 3 $F_3=377N$

Direction 1 $\theta_1=145 degrees \approx 35 \textdegree (2nd qudrant)$

Direction 2 $\theta_2=303 degrees \approx 57 \textdegree (3rd qudrant)$

Direction 3 $\theta_3=77 degrees$

Generally Resolving forces to X axis is mathematically given by

$\sum f_x=337cos77+331cos57+226sin35$

$\sum f_x=351.596N$

Generally Resolving forces to Y axis is mathematically given by

$\sum f_y=337sin77+331sin57+226cos35$

$\sum f_x=810.788N$

Generally the equation for Resultant force R is mathematically given by

$R=\sqrt{\sum f_x^2+\sum f_x^2}$

$R=\sqrt{351.596^2+810.788^2}$

$R=883.74N$

P/-8 + 9 > 13 pls explain i don't get it

KonstantinChe [14]

Answer:

p < -32

Step-by-step explanation:

Given: p/-8 + 9 > 13

Rewrite: $\frac{p}{-8}$ + 9 > 13

Subtract 9 from both sides: $\frac{p}{-8}$ > 4

Move the negative (it is a fraction): $\frac{-p}{8}$ > 4

Multiply both sides by 8: -p > 32

Times by -1 (-p -> -1p): p > -32

Flip the sign (multiplied by a negative): p < -32

Hope this helps, have a nice day :D
