Hey there! :)

Answer:

1124.8 J.

Step-by-step explanation:

Given:

Distance: 25 meters.

Force: 70 N.

Direction: 50° with the horizontal.

Start by calculating the magnitude of the vector:

cos (50) = |x| / 70

70 · cos (50) = |x|

Solve:

44.99 ≈ |x|

This is the magnitude. To calculate the amount of work done, simply multiply by the distance she pushed the wheelbarrow:

44.99 × 25 ≈ 1124.8 J.

HELP HELP !! & PlEASE SHOW WORK ! What would be the compound interest rate if Tom borrowed $6,000 at a 3% interest rate for

In-s [12.5K]

Answer:

Compound interest = $365.4

Step-by-step explanation:

Given:

Amount borrowed = $6,000

Rate of interest = 3%

Number of year = year

Find:

Compound interest

Computation:

A = P[1+r]ⁿ

Amount after 2 year = 6,000[1 + 3%]²

Amount after 2 year = 6,000[1 + 0.03]²

Amount after 2 year = 6,000[1.03]²

Amount after 2 year = 6,000[1.0609]

Amount after 2 year = 6,365.4

Compound interest = Amount after 2 year - Amount borrowed

Compound interest = 6,365.4 - 6,000

Compound interest = $365.4
