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.

Find the x intercept and y intercept x + 18 = 9y .
Natalka [10]
First you need to put it into y=mx+b format and which is 1/2x + 2 =y. The y intercept should be b in the equation y=mx +b so y=2. The x-intercept should be when y=0 and x equals a number which is x=-4. X-intercept=-4 and y-intercept=2.

First find the area of the triangle.

\sf A=\dfrac{1}{2}bh

\sf A=\dfrac{1}{2}(6)(12)

\sf A=36cm^2

ABCE is a parallelogram, this means that the area of triangle ABE is equal to the area of triangle EBC. The are of the entire trapezoid is 180 square centimeters, we already found the area of the triangle, so that leaves us with:

\sf 180-36=144

So the area of the entire parallelogram must be 144 square centimeters. So each half of the parallelogram must be equal to:

\sf 144\div 2=\boxed{\sf 72cm^2}

A and B can do a work in 3 days but A working alone takes 4 days. In what time will B do it if he works alone?
zalisa [80]

Answer:

Let B have x days work:

A + B = 3 days

1/4 + 1/x = 1/3

1/3 - 1/4 = 1/x

1/12 = 1/x

x = 1 / (1/12)

x = 12

B takes 12 days

I do not know if this is right
