A worker pushes a wheelbarrow with a force of 20N downward and to the left, as shown in the figure below. The angle the handle m

akes with the horizontal is 34°. Note that the figure is not drawn to scale. Write the force vector F in the form =F+aibj. Do not round any intermediate computations, and round the values in your answer to the nearest hundredth. f=

Answer:

The values of F will be "16.58 i + 11.18 j".

Step-by-step explanation:

The given values are:

Force, F = 20 N

Angle, Ф = 33°

The formula use in the given scenario will be:

⇒  x=a \ Cos\theta

⇒  y=a \ Sin\theta

Now,

For Force, F=ai+bj

⇒  a=F \ Cos\theta

⇒     =20 \ Cos(34^{\circ})

⇒     =20\times .829

⇒     =16.58

and,

⇒  b=F \ Sin\theta

⇒     =20 \ Sin(34^{\circ})

⇒     =20\times .55

⇒     =11.18

So that,

⇒  F=16.58 \ i+11.18 \ j

Help me solve this equation. Find f(x)-g(x)
mojhsa [17]

Answer:

- 2x³

Step-by-step explanation:

f(x) - g(x)

= x^{\frac{1}{2} } - x - (2x³ - x^{\frac{1}{2} } - x) ← distribute parenthesis by - 1

= x^{\frac{1}{2} } - x - 2x³ + x^{\frac{1}{2} } + x ← collect like terms )

= - 2x³

KiRa [710]

Answer:

Caitlyn's average is roughly 11.4.

Step-by-step explanation:

You get this by dividing 46 by 4, which gets you 11.5.

You then divide 79 by 7, that equals 11.3, rounded.

The number in-between the two numbers is 11.4.

Hope this helps!

Pls mark brainliest! ;)
