Forces of 9 lbs and 13 lbs act at a 38º angle to each other. Find the magnitude of the resultant force and the angle that the re

fiasKO [112]

Answer: $R=20.84\ lb\quad 22.57^{\circ},15.43^{\circ}$

Step-by-step explanation:

Given

Two forces of 9 and 13 lbs acts $38^{\circ}$ angle to each other

The resultant of the two forces is given by

$\Rightarrow R=\sqrt{a^2+b^2+2ab\cos \theta}$

Insert the values

$\Rightarrow R=\sqrt{9^2+13^2+2(9)(13)\cos 38^{\circ}}\\\Rightarrow R=\sqrt{81+169+184.394}\\\Rightarrow R=\sqrt{434.394}\\\Rightarrow R=20.84\ lb$

Resultant makes an angle of

$\Rightarrow \alpha=\tan^{-1}\left( \dfrac{b\sin \theta}{a+b\cos \theta}\right)\\\\\text{Considering 9 lb force along the x-axis}\\\\\Rightarrow \alpha =\tan^{-1}\left( \dfrac{13\sin 38^{\circ}}{9+13\cos 38^{\circ}}\right)\\\\\Rightarrow \alpha =\tan^{-1}(\dfrac{8}{19.244})\\\\\Rightarrow \alpha=22.57^{\circ}$

So, the resultant makes an angle of $22.57^{\circ}$ with 9 lb force

Angle made with 13 lb force is $38^{\circ}-22.57^{\circ}=15.43^{\circ}$

he weight of a chimpanzee, y, in pounds, x months after birth is modeled by the equation y=1.5x+8. Which represents the equation

soldi70 [24.7K]

The equation that represents x when solved is $x=\frac{y-8}{1.5}$

Given the equation that expresses the weight of a chimpanzee with respect to the months of birth as:

y = 1.5x + 8

We are to express x in terms of "y"

$y = 1.5x + 8$

Subtract 8 from both sides

$y -8= 1.5x + 8-8\\y-8 = 1.5x\\Swap\\1.5x = y - 8$

Divide both sides by 1.5

$\frac{1.x}{1.5}= \frac{y-8}{1.5} \\x=\frac{y-8}{1.5} \\$

Hence the equation that represents x when solved is $x=\frac{y-8}{1.5}$

Which expression matches the verbal description below?

Ronch [10]

Answer:

Quotient = division of one number by another

$\implies \textsf{quotient of 30 and 6} = \sf \dfrac{30}{6}$

$\implies \textsf{3 subtracted from } \sf \dfrac{30}{6}=\dfrac{30}{6}-3$

The quotient of 30 and 6 can also be written as the ratio 30 : 6

Therefore, the solution is (30:6) - 3
