Resolving horizontally .  Make  forces to the right positive 
resultant force =  70cos30-60cos60 = 60.62-60 = 0.62 lbs

resolve vertically  
resultant force =   120 sin60 - 70 sin30 = 103.92 - 35 = 68.92   lbs in downward direction

magnitude of the ressultant forsse = sqrt(68.92^2 + 0.62^2) =  68.92 lbs

direction of the force =  tan-1 (0.62 / 68.82) = 0.52 degrees east of south or  
a bearing of 
90 - 0.52  =  89.48 degrees

Find the mean, median and mode of these sets of data: a. 14,12,24,36,23 c. 2,3,4,5,30 b. 114,112,124,136,123 d. x, 2x,3x,4x,5x
prisoha [69]

Answer:

first u need to rearrange the three sets of data in ascending order

i'll just do a set here as an example

a: 12, 14, 23, 24, 36

Mean: (12+14+23+24+36)/5 = 21.8

Median: 23

Mode: 0 (as none of the datum is repetitive)

Rewriting expressions using algebraic properties doesn't change the value of the expression or the relationship it describes.
kiruha [24]

Answer:

  see attached

Step-by-step explanation:

No doubt you have examples showing the wording that is expected to be used here. We have made a guess.

power of a ratio: the numerator is raised to the power, as is the denominator. (a/b)^c = (a^c)/(b^c)

power of a product: each factor is raised to the power. (ab)^c = (a^c)(b^c)

power of a power: the powers are multiplied. (a^b)^c = a^(bc)

quotient of powers: the result when one power is divided by another is the difference of the numerator and denominator powers. (a^b)/(a^c) = a^(b-c)

_____

<em>Additional comment</em>

The order of operations tells you to simplify inside parentheses first. Doing that reduces the work somewhat.

  \left(\dfrac{-3x^3y}{x^2}\right)^4=(-3xy)^4=(-3)^4x^4y^4=81x^4y^4

The coefficient of -7x is -7, since -7 is the number being multiplied by x.

Similarly, the coefficient of 9/4y is 9/4, since it is the number being multiplied by y.
